Replacing old rubber roof with IB PVC roofing membrane in Lowell, MA.

In the beginning of Dec. 09 we installed a new IB PVC roof in Lowell, MA. This roof replaced an old EPDM rubber roof which was installed by a hack roofing contractor about two years ago, and was failing miserably, due to two factors: poor roofing system design on the part of EPDM roofing and horrible installation by the roofing contractor, who as I suspect had almost zero knowledge about flat roofing and rubber installation. Before I go into the IB roof installation, I wanted to talk a bit about the two above-mentioned factors contributing to rubber roof failure.

The roof actually consisted of two roof sections not connected to each other. One smaller roof in the front of this historic home, was about 100 sq. ft. in total, but its shape made using a rubber roof not feasible due to limitations / flaws of rubber roof system design. Another roof section was just over 300 sq. ft. and covered enclosed porch in the rear of the house. This section had a low slope to it (about 2 in 12 pitch) and a hip roof design. The failure of both front and rear roof sections was a result of bad installation by the roofing contractor and EPDM rubber roof shrinkage as well as seam adhesive failure.

Rubber roof failure due to EPDM flaws and limitations and faulty installation my roofing contractor:

When EPDM rubber roofing membrane is installed on a roof connected to a wall of a building, the membrane must be laid down with a flap going up the wall – in essence, the wall flashing and the roof covering must be done with one piece of material to eliminate leaks the the roof to wall connection. therefore the field sheet of roofing membrane is only held down by glue (which happens to break down after 5-7 years). While in some cases this work out fine, very often the rubber shrinks and pulls away from the wall-to-roof connection point. This results in ether detachment of wall flashing, membrane pulling away from the corner of roof to wall connection, or in some rare cases, when wall flashing is securely attached to the wall, the shrinking rubber roof may pull the wall with it – for example it can pull a brick parapet wall.

IB PVC roof is installed differently. All membrane is terminated at the roof to wall connection with heavy duty fasteners (screws r masonry anchors) and barbed plates, to hold the membrane down. A separate wall flashing is installed up the wall and 5-6″ away from the wall, covering the screws and plates, and is welded to the roof, making the wall flashing watertight. The wall flashing is attached to the wall using either an aluminum termination bar, or nailed to the wall in cases when it will later be covered by siding.

At the edges of the roof, a PVC coated drip edge is installed into pressure-treated (PT) wood nailer, using roofing screws to securely attach it to the roof deck, and to prevent wind uplift. Then the IB PVC roofing membrane sis welded to the drip edge. In case of rubber roof, the drip-edge is nailed down with smooth-shank roofing nails. This makes pull-out very easy – strong wing can pull the rubber roof off, or as in this case, the rubber shrinkage pulled the whole assembly away from the roof edge. In rare cases, rubber roofing contractor will use the roofing screws to attache the drip edge. Most of the time, roofing contractor will install drip edge right over soft insulation, with 2 or 3′ roofing nails. You can easily pull off this drip edge by hand, even if its nailed 6″ o.c., as we did on this roof.

IB flat roof installation:

Roof Insulation: The homeowners who just purchased their Lowell, MA home recently, wanted to improve insulation over the back porch, while the front roof was already insulated between the rafters. We used 24–r value, 4-inch Poly ISO insulation board on the back roof and 1/2 inch fan-fold insulation in the front. The design of the rear roof section and the short distance between the two rear windows and the roof, made us use tapered insulation to actually reduce the thickness of ISO board from 4″ to 2″ at roof to wall connection. This allowed us to properly flash the roof to the wall, though gradually reducing insulating value from 24-r down to 12-r at the wall.

Roof tear-off: To keep installation costs and land-fill waste down, while installing the roof in accordance with MA building code (which allows no more than two layers of roofing material, unless approved by structural engineer and building inspector), we removed one layer of rubber roof and the fiber board, leaving old tin roof on the front roof and rolled asphalt on the rear roof in place.

Day one – installation of smaller front roof.

First thing we had to do on the first day was to get a roofing permit from Lowell building department. Since homeowners just recently bought their house, the building department did not catch up with the assessor’s office on current owners of the property (and why would day do any extra work if they don’t get paid for it?),so it took us some time to square things out.After we got the building permit, it was placed in the appropriate spot – front window of the house. Now it was time to get to work.

The roof was installed between to snow-storm – one right after Thanksgiving and another one just a few days later. On the first day we had to shovel all the snow off the front and rear roof, and removed the rubber membrane off the front roof. We decided to leave the rubber on the rear roof until we actually had time to get to it, since it was supposed to snow and rain the day after.

Once the rubber roof was removed, we installed the perimeter wood nailer and laid down the insulation. We then installed the drip edge and sheets of IP PVC roofing membrane, which were pre-cut on the ground, to simplify installation on this already tight roof. IB membrane was welded to the PVC coated drip edge and mechanically fastened down to the roof deck with heavy duty screw and plate in-filed and along the roof to wall connection.

Roof to wall flashing: A separate roof to wall flashing was installed, and welded to the roof, and nailed to the wall and attached with aluminum termination bar along the exposed wall. Inside and outside corners were flashed with IB non-reinforced corner flashing material. which was welded to the roofing membrane.

At the end, an IB 5″ two-way air-vent was installed remove the condensation between the roofing membrane and insulation. In, installation of roof to wall flashing took as lone as the rest of roof installation. Since the roof to wall flashing was the main part of rubber roof failure and the most difficult part of this installation, we had to spend extra time, making sure this one will last a lifetime.

Day two – installation of the rear roof.

Rubber roof tear-off, insulation and IB membrane  installation all had to done in one day, so the roof would be watertight after we left job site for the night. We left all finish and detail work for last day – our main goal was to have the roof covered at the end of work day. Fortunately for us, the rubber roof came off very easily, as the glue barely held it, and drip edge was popping of like popcorn. We also removed the old fiber-board, to maximize the clearance between the window sills and the roof.

Once old rubber roof was removed, we started laying out our 4 inch high wood nailer along roof’s perimeter. We used double 2×6 PT boards with 1/2 inch strips of PT plywood in the middle – this gave us almost 4″ total thickness, to match the thickness of ISO insulation. When the wood nailer was installed, we laid down the double 2″ insulation boards along the outer perimeter of the roof. At this point we had to start the tapered insulation. We first laid down 1″ ISO board and then double sheets of 1/4″ per foot tapered ISO, to bring the total insulation thickness from 4″ to 2″ over 4 feet distance.

Once all insulation was laid out, and fastened down according to FM Global insulation fastening standards (8 fasteners per 4×8 sheet of insulation), we installed the pre-cut rolls of IB membrane, which was fastened down 12″ O.C.

First we installed a perimeter half-sheet roll, and then a full width roll, butting it against the wall. Now it was time for roof to wall flashing and termination. Our roof to wall flashing was made out of 3 pieces of 2 feet wide IB membrane to have appropriate up-the-wall flashing. After roof to wall flashing was installed and all seams welded, we installed two outside corner flashing. Now the roof was watertight, it was already dark, and time to go home.

Day three – installation of drip-edge, cover tape and cedar clapboard siding.

On the last day we installed the special order 5″ wide face drip edge which was installed over the IB membrane, and a 6″ IB cover tape was welded down to the drip edge and the roof. All joints between the 10 foot sections of the drip-edge sealed according to IB installation spec to prevent roof damage from expansion and contraction of the metal. A 2″ foil-tape was placed over the joint and a 5″ IB flashing material was welded on top. We also replaced the old cedar clapboard siding which was rotted and fell apart after we removed it to install the roof to wall flashing. Although it does not seem like a lot of work, it actually to us entire day to complete. As the last finishing touch, a 5″ two-way membrane vent was installed in the center of the roof.

Information for homeowners regarding flat roofs:

Words of caution  we strongly recommend home and building owners to avoid installing EPDM rubber roofing membrane. Besides the faulty design of this roof, there are too many shady contractors, with little or no experience, who can buy rubber roofing material at almost any roofing supply warehouse. You may be attracted to seemingly low price of EPDM rubber roofs, but be aware that low price comes with VERY low quality of workmanship, and to compensate for low prices, these contractors will use cheap rubber glue and accessories.

When you choose to go with a quality flat roofing product like IB Flat Roofs and a professional contractor, you will not be paying twice for a new flat roof and dealing wit roof leaks and finding your rubber roof installer to fix the leaks, like the one bellow:

Leaking rubber roof in Quincy, MA, installed directly over asphalt shingles:

Look at the picture above – it is a 1 year old EPDM rubber that was installed by a shady “rubber roofing specialist” contractor, who disappeared, and does not return home owner’s phone calls. They glued the rubber membrane straight to asphalt shingles roof, which you can see “telegraphing through the rubber. This roof has leaking ever since it was installed. Read more information about rubber roof materials, roofing contractors and their training in installation of rubber roofs (or lack of such training) in our rubber roofing guide for flat roof owners.

As you may know, we specialize in installation of IB roofs – premium grade PVC flat roofing membranes, with fusion hot-air welded seams which ensure permanent lap bond, and as a result, leaks-free performance. At the same time if you have a rubber roof, which is in fairly decent shape, but has developed some leaks due to lap sealant (epdm rubber glue) failure, we can repair your rubber roof fairly inexpensively, as compared to installing a new IB roof, and extend the service life of your rubber roof. Learn more about our rubber roof repair services in MA, CT and RI. We want you to know that although we repair rubber roofs, we will not install it, because for us it is an inferior roofing material with too many limitations and possibilities to develop roof leaks.

Here we will explain you how these repairs work and what you can expect, as well as show a few roof repairs in Massachusetts which have done recently. We also recommend that your read our Rubber Roofing guide, which explains the shortcomings of rubber roofs, and explains why we advise home owners to stay away from EPDM rubber roofing systems due to product limitations and overwhelming number of dishonest roofing contractors eager to install rubber roofs, without proper knowledge of this system. Instead we recommend installing IB Flat Roof – a PVC single ply flat roofing systems with hot-air welded seams which will not break down as rubber roof seams tend to do after 5-7 years.

We also want to let the flat rubber roof owners know that any rubber roof repair or installation must be performed in temperatures above 40 degrees F, as the primer / adhesives will otherwise freeze or be too cold to properly dry/tack and provide proper adhesion. Unless your roof repair is more of an emergency, we recommend postponing it until the warmer temperature sets in. If your roof repair is an emergency, special measures can be taken to keep the adhesive warm and on a sunny day the black rubber will be warmer then outside temperature, so repair can be done even on a colder day. We strongly advise you against installing a new rubber roof in general and in the winter especially. Read more info on pros and cons of winter roofing, and keep in mind that IB flat roofs can be installed in any tempereature, because they are not glued, but hot air welded.

EPDM rubber roof repair in Brookline, MA:

As  you drive on Newton St. in South Brookline, there is a big apartments complex, located right next to Exxon gas station. This apartment complex has a fairly recent Carlisle EPDM rubber roof which is about 7-10 years old (according tho property manager), but due to some ponding water, this roof has developed leaks in some spots, which the management had to repair, before small leaks escalate into bigger problems. Since EPDM rubber roofs are not warrantied for any type of ponding water (water that  stays on the flat roof for more than 48 hours after rain), I made an note for the complex management that their small leaks can turn into bigger problems if actions are not taken. However, thir ponding water problem was not as severe as in other cases, because the water was able to drain through the Roof Drains located  in different parts of the roof. Also, the skylights which are spread through-out the roof create additional potential leaks.

We’ve inspected the roof with seam probe to find obvious separated seams, and to the owner’s relief, the seams were in more or less decent shape. However the corner flashing on the roof fire exit were worn out and developed holes in them which had to be repaired. We used the peel-and stick quick-applied rubber flashing, which is an uncured rubber material and can stretch to conform to the required shape (and inside or outside corner, pipe flashing, etc.). After installed, uncured flashing material will cure under the sun’s UV rays,, while keeping its new form. Peel and stick rubber flashings are applied with the EPDM primer which ensures better adhesion and longer lasting repair.

Once the uncured flashing is installed, it is already watertight and just need to cure, and take its new permanent shape. The the edges of all flashings are also caulked with EPDM lap sealant for additional water-tightness. The uncured EPDM flashing material is installed on odd-shaped roof penetrations. If you need to flash a straight line, such as lap seam, a special EPDM rubber cover tape is used. It is also a quick-applied peel and stick materials, but already cured, and will retain its existing shape. Read on to learn how EPDM cover tape is used to re-seam a commercial roof to dramatically extend its service life.

Rubber roof repair in Boston, MA:

This is a commercial office building in Boston, which has developed leaks in different parts of seam overlaps between separate sheets of rubber membrane. The roof is a 60-mil EPDM rubber, made by Firestone, with river rock ballast to hold the membrane down. We had to shovel off all the ballast away from the seams, so we could clean and repair them.

Once the loose gravel is broomed ad shoveled off the seam joints, the seams had to be wiped clean with the EPDM rubber cleaner. You should know that many “rubber roofers” will use gasoline to clean the seams, instead of the cleaner, which costs almost twenty dollars per gallon, instead of gasoline being under $3 right now. However, rubber should not be cleaned with gasoline, as oil based products will actually break down the EPDM membrane with time. Even though gas will evaporate before it will have a chance to do any real damage, it will certainly not be beneficial to you as a roof owner if your roofing contractor washes seams down with gas. Rubber roof manufacturers strongly object to roofers using gas to clean the seams. However they can do very little to enforce this, so it is often the responsibility of of an honest roofing contractor to not use gasoline to clean the membrane, and the roof owners should also inspect the roofer while the roof is being installed, to make sure the get quality installation.

Notice in the picture above, while one roofer is cleaning and soaking the seam area with membrane cleaner, the other roof uses rough push broom to clean off the tough dirt, so that there is proper adhesion between the rubber membrane and seam tape.

Once the area is cleaned with membrane cleaner, a rubber primer is applied to the are of contact, and the let to be dried to the point of being tacky. After primer is dry, the peel and stick seam tape can be applied. The special chemical on the peel and stick tape make use of rubber glue (splice adhesive) not necessary. The primer acts as a glue and actually creates a stronger bond than the splice adhesive.

In fact, the introduction of peel and stick seam tapes and other flashing materials for rubber roofs, made the entire system a lot better than it was when only option was the splice glue, which would often fail in 5-7 years after original roof installation. With peel-and-stick roof accessories the rubber roofs now can last 10-12 or even more years, before re-seaming is required.

Once the EPDM primer is applied and allowed to dry for a few minutes, the Peel and Stick cover tape is installed and carefully rolled in using a Silicone roller, to push out any air bubbles and ensure stronger, even adhesion between the roof and a cover tape. When all tape is installed, edges are caulked with EPDM lap sealant for additional protection. Now this roof should last at least 5 more years before additional repair or replacement is required.

On commercial re-seam repair work, we can offer a bi-annual roof inspection / service contract with three years water-tightness warranty, which VERY few roofing contractors can offer. Warranty and service contract can be discussed separately, when we give you a roof repair estimate. Neither is included by default into our standard rubber roof repair service.

Rubber roof repair in Lexington, MA – chimney cracks and copper counter flashing:

A more recent, residential rubber roof repair, that was done on the roof of a “newly historic home” in Lexington, Massachusetts in November, 2009. Homeowners had a new rubber roof installed in 2002 by a New Hampshire construction company which is now out of business, and could not provide roof repair. After about seven years roof began to leak around the chimney. Prior to this leak, the original roof installer was supposed to install a lead counter flashing around the chimney. They skipped this part of roof installation, and had to come back and do it, after homeowners confronted them with the issue.

As I came to inspect the roof I noticed that there were large soft spots around the chimney corners. The lead flashing was eaten by squirrels on all four corners of the chimney, and the chimney itself had multiple cracks in the brick, mortar, and old cracks which were sealed with some type of exterior caulking, which was now failing. Other then that, to my surprise I could not find any actual leaks in the rubber roof. The design of the house, which is a butterfly roof sloped down from the center, makes this roof virtually leaks-free unless the roof  installation is a complete hack job. It was also more or less properly installed with 3″ peel-and-stick seam tape, seams overlapping in the downward direction, and single-piece pipe boots.The only part that could leak was the chimney membrane  flashing, but it was also in a very decent shape and seam-probe test shown no separations between the roof and chimney flashing.

Only after the lead flashing was removed, I found a small separation in the chimney flashing at the corner, which was eaten by squirrels. This flashing separation could potentially leak, though would be a minor contributor. I concluded that most of the leaks come through the chimney cracks, which had to be thoroughly cleaned off old caulking and wire-brushed, to allow the new sealant to properly adhere to the brick. I also recommended to replace the damaged lead counter-flashing with new Copper flashing, which would last a lot longer and squirrels would not chew it.

I started out by removing old lead flashing and cutting a continuous 1″ deep grove into the chimney, in which new copper flashing would be permanently inserted. This grove was made in the brick itself, and not into mortar joints, which are much softer and do not provide sufficient strength for the counter-flashing. Once the cuts were made and all the brick dust was cleaned out of the grove and the roof, I began cleaning out the cracks in the brick and removing old caulking.

Once all prep-work was completed, it was time to flash the only rubber material separation found around the chimney. I thoroughly cleaned the rubber membrane with rubber cleaner, applied EPDM primer and installed the peel-and-stick, uncured flashing, which covered both sides of the corner, as well as base of the corner flashing and the seam separation that I found after lead counterflashing was removed.

After all cracks were thoroughly cleaned, wire-brushed and the corner flashing was installed, I began making the new copper counter flashing. We used a 16 oz. copper sheet to cut and field bend a 12 inch wide flashing which would be inserted into the groves. The 16 oz. copper is very thick, as compared to aluminum or steel – it is almost 1/16″ thick metal. This makes it a bit difficult to work with, even though it is softer than steel.

The new copper flashing pans were first cut and bent, to properly fit around the chimney, but wer not permanently put in until all four sides of the chimney were done. The first pan was installed at the bottom of the chimney. Then the side pans overlapped the bottom pan at the corners of the chimney and than the back pan overlapped the the side pans, making it an completely watertight chimney counter flashing.

As we were installing the copper pans, we had an unexpected visitor on the roof. The visitor snuck up behind our back, and quietly climbed onto the roof. This visitor was more than unexpected, as would never imagine seeing on go to the roof. It turned out to be a neighbor’s cat which was very pretty and absolutely not afraid of us, or the noise we were making. The cat climbed up the ladder, inspected the situation, made sure we were doing good job and disappeared for a while. It later came back for a final roof inspection.

Under strict supervision of the neighbor’s cat we carried on with installation of the copper counter flashing. Once all pan were, cut, bent and tightly fitted, we removed them from the chimney and installed premium roofing caulking sealant (Solar Seal 900) which would hold the pans in place as well as make them watertight. We also sealed all the cracks in the chimney, to make sure water was neot getting through those cracks.

Once all the caulking was applied, the pans went back in, and permanently sealed with additional bead of caulking. the pans were also locked into each other to prevent separation by strong wind. The chimney ar rubber roof repair was now complete with a new, long-lasting copper flashing reglet.

Virtually, all roofing systems the industry has to offer present certain advantages of use, benefits and drawbacks. Metal roofing is not an exception and just like any other roofing system it offers benefits, and drawbacks in the parameters in which metal roofing is lacking, for instance initial cost of metal roofing is often sited as a major drawback however, it all depends on the perspective you take. We will come back to the initial cost of metal roofing investment in a bit, and analyze it in greater detail, but for now let’s focus our attention on benefits of metal roofing.

One of the greatest benefits in favor of metal roofing for residential uses is that a metal roof can outlast conventional roof by a a significant factor. One of the dimensions for measuring any given roofing system attractiveness is its longevity, which can be well over fifty years in metal roofing. Fifty years! Imagine that, that’s half a century, but you can only get such a long lasting roof, when it was installed by well trained Metal Roofing Contractors, who took their time to install metal roof correctly. It means that the installers not only followed metal roofing manufacturer’s installation requirement, but also took into account overall condition and functioning of the roof in question, and made any and all, necessary improvements, changes and adjustments with regards to roof ventilation, insulation, roof deck condition, and other factors that comprise a fine working roof.

With regards to longevity of a metal roofing system, it is important to keep in mind that not all metal roofing systems are created equal. For instance, I once had a displeasure of working with a fine looking metal shake roofing systems by Atas manufacturing, that was poorly designed, did not have a good wind uplift, lacked in terms of metal shake lock design, which compromised its reliability, and required a roofing pitch of at least 7 to 12, which indicated that the system was prone to leaking. This system was called Rumba Shakes, and I had no choice but to install it because it was specified by the client who ordered that metal roofing system. Well, We did the best we could with the Rumba Shake metal roofing system, and that roof still functions fine today, but we were quite worried about the small locks of the metal shakes during metal roofing installation.

Later on, when we received an order for an installation of another metal roof with similar metal shake design and blue color, I came to find out that manufacturer has discontinued this particular metal roofing system for reasons unknown to me…. As a result, I had to spend quite a bit of time before we finally found a manufacturer who agreed to purchase blue color aluminum coil and stamped the metal shakes for our order. Interestingly enough, the new metal roofing system was made with noticeably lesser gauge or thickness of aluminum, yet the design of its locks was far superior, which is important, because lock is critically important feature of any interlocking metal roofing system.  The new alternative metal shake roofing system was way more reliable than a similar looking, but functionally inferior rumba shake we have installed before. Take a look at the photograph I took of two shakes side by side.

You may also note, that the functionally superior shake with larger lock, also looks more like a shake and it uses less aluminum for the shake itself. Sustainably speaking, we are talking about going green in style here!

At this point, you are probably asking yourself what is the whole point of my rant about the lock mechanism features of these two metal roofing system. Well, I will tell you from the installer’s perspective, we want to do the job right the first time and never have to come back again. I am talking about reliability of a metal roofing system, and that although metal roofs are far superior to conventional roofs, they are not created equal, and when you go with a metal roof that has flaws in the design of the system or its flashing, you may well encounter unpleasant problems such as roof leaks down the road. So, this is just a little something to be aware of.

Here is the alternative metal roofing system we managed to get, picture take during installation on an IHop in Brighton, MA

Thus, we have established that not all metal roofing systems are made the same, and that as a consumer you should do the due diligence, and research metal roofing materials in question before you commit to any particular system. One of the ways to learn more about metal roofing materials and the system specific benefits is to go to a Roofing supply warehouse and ask to speak to a person in charge of metal roofing products division. You can ask them if they can recommend a good metal roofing system for your particular situation. Be sure to ask, why they think that the recommended system will work well for you. In other words, they should explain the benefits of a metal roofing system they recommend. They can also refer you to metal roofing contractors who install this particular metal roofing system. But your homework is not done here, in fact it only begins…

One, of the benefits of modern metal roofs is the wide selection of cool roof rated metal roof colors designed to reflect solar radiant heat, reducing the heat gain in your home it the summer and helping to save money on AC costs. When the night sets, in the summer, metal roof will quickly emit the heat gained back into the atmosphere, where as asphalt shingle roof will remain hot for hours.

In the winter metal roof, can help you prevent ice dam formation, and ice build up. Modern metal roofs are coated with specialty coatings that allow snow to slide off the roof virtually eliminating the ice dam formation. In places where falling snow is undesirable, a metal roof can be equipped with specialty snow guards.

I can hardly imagine ice dams forming on this sheet metal roof, that will stand for decades.

Metal Roof, can set your home apart form the rest. Did you know that when you are looking at any given house, its roof is a half of what you see. Replacing an existing mediocre looking asphalt shingle roof with a more attractive metal roof, will do wonders for the curb appeal of your home. Not only that, it will appraise the value of your property.

Metal roof that was installed correctly will help you eliminate for unnecessary roof repairs and expensive maintenance down the road. I guess it is another way that you could be saving money in the long run.

Now, you have heard the tales of incessant noise from a metal roof when it rains, right? Well, guess what that is not the case at all with modern metal roofing. I fact, they are awfully quiet, but do not get sleepy, yet!

Have you heard that saying that green proponents often use; Reduce, Reuse, Recycle! Well guess what? Metal Roofs are made from a significant proportion / content of recycled metal, and likewise can be recycled at the end of their service life, but it is going to be very long life, of course, given that you found a good metal roofing installer to do it right in every regard.

And speaking of green building and sustainability, modern metal roofs such as sheet metal roofing systems, can be outfitted with thin film solar roofing panels that can transform solar energy into electricity to power your home.

If you have question about a metal roofing system you consider, ask away in the comments and we will answer it on this roofing blog, and no self promotional posts please.

Massachusetts is our home state and here is where we install majority of our roofs (with Connecticut being in second place). In Massachusetts, roofing market is very different, depending on location, and although there are a lot more sloped roofs, not only in Mass., but in the rest of the country, we still install more Flat roofs than Metal roofs. As for geographic location of your home in Massachusetts, up north, toward the New Hampshire border, roofs are more prone to Ice Dam roof leaks and damages than houses located in the southern MA.

Although Massachusetts is not a very big state, the your location can have a dramatic effect on the amount of snow fall in the winter, and thus your chances of having Ice dams and and related roof leaks. For example on the same day, an average roof in Sharon or Norwood will have 1-2 inches of ice alone the eaves, whereas an average roof in Lowell will have 5+ inches of ice build-up. If you go further north of south away from Boston the amount of annual snow accumulation and ice dams will increase or decrease respectively.

Why do I mention Ice dams and roof leaks in the intorductory part? It’s simple – most commercial roofs are flat, and are not prone to ice dams, though they have their own list of problems that I will discuss bellow. Residential roofs on the other hand are the ones mostly affected by ice dams. These are both sloped roofs and low-slope / flat roof, and we have the best and longest lasting solutions for both - Metal Roofing for sloped roofs and IB Roof for low slope flat roofs, such as shed dormer roofs, and completely flat roofs.

Bellow we will give you a quick overview of most recent and some older roof installations that we’ve completed in Mass. Keep in mind that these are not the complete job profiles. Complete job overviews will be posted separately, as time permits us to write them. In the overviews bellow I will provide basic information about each roof, accompanied by a few pictures and short description of roof installation process and challenges we had to face.

Before we go into job reviews, here are a few additional articles you may find useful, when choosing a roof product for your home and a roofing contractor to install it:

How to prevent Ice Dams – comprehensive guide on which focuses on the root cause of Ice dams which is usually a combination of poor ventilation and and inadequate insulation in the attic space or between roof rafters. This guide will help homeowners minimize heat leaks in the attic, improve ventilation and eliminate the effects of ice dam leaks by installing a Metal Roof or an IB low-slope roofing membrane.

Low-slope roofs – Overview of common problems associated with low slope residential roof such as shed dormers or roof on most cape-style homes located in the norther MA. Common issues with such roofs include rotten roof decking / rafters and Ice-dams. Since this roofs are prone to Ice dam leaks, most of the rot damage is an effect of ice dams and although many roofing contractors will insist that using Ice and Water shield will do the trick, our experience shows that most of the time I&W fails to protect the roof even if entire roof deck is covered in Ice and Water. Therefore we believe that best solution for permanent protection of low-slope roofs and eliminating ice dams is the use of metal roof of IB flat roofing membrane in conjunction with solving ventilation/insulation issues described in the article above.

Roofs we installed in Massachusetts:

Low slope shed dormer roof in Westminster, MA

This roof we installed in early May of 2009. The house is located in heavily wooded are of central Mass, just north of mount Wachusett. Westminster, MA is located along Rt. 2, and not very far from New Hampshire border. These areas get major snow falls in the winter, together with colder temperatures than those in Boston and ice dams are a major problem in Westminster, even for high slope roofs. Low slope roofs such as the one we replaced there, are very likely to have ice dam leaks and other problems such as rotten roof deck, wet insulation, and mold.

The roof has been leaking for some time around the chimney in the center of the roof and was patched many times with tar, but rather unsuccessfully. Also, due to Ice Dams and roof leaks caused by ice formation along the roof eaves, the home owner installed heating cables to stop the Ice dam leaks. These however did not help either and after one more unsuccessful roof repair, home owner decided to get an IB roof installed.

The home owner and their cousin who is a roofer in NH, did the roof tear-off and replaced all rotten plywood decking, to reduce the cost of roof installation, while we installed the roof itself, insulation, chimney flashing, ridge vent and snow guards (snow retention system).

Note – even though before we installed IB roof, home owner’s main concern was to get ice and snow off the roof. After IB roof was installed, our concern was that due to roof’s pitch, which was about 3 in 12″, the snow and Ice would just slide off the roof in a large pile, crushing down onto deck and perch bellow it. Also there was a grill on the deck which was not movable since it was tied to a gas line.

The chimney flashing, which may seem to take not to much time, actually took about 6-7 hours to properly flash. The reason ot turned out to be so lime consuming it that it is located in the center and separates the ridge vent as well as creeping onto another side of the roof. Due to its position, size and the way IB roof is installed it not only took long to work around, but also slowed down the rest of roof installation. Because the the ridge vent buts into the chimney, we had to make sure that not only ridge vent is raised an inch off the roof level to prevent the wind-driven rain from leaking into the house, but also that it is completely tied to the roof, and flashed up the chimney. Once the chimney flashing was installed and counter flashing reglet had to bi installed as well.

All in all it took us 3 days to install this roof, though 3rd day was rather short. What really slowed us down, was the first heat wave of that spring and unrealistic number of bugs / flies / mosquitoes in this wooded / swampy area of central Mass.

Roofing membrane used: 50 mil mechanically attached IB PVC flat roofing system.

Insulation used: 1/2″ fan-fold Styrofoam insulation with clear plastic / metal facing.

Total roof square footage: Approximately 500 sq. ft.

Standing seam metal roof in Wayland, MA.

Right after the roof in Westminster was installed, we started getting ready for a big metal roofing project, which used .032 Aluminum standing seam metal roof in 1 3/4″ snap lock profile with 16″ wide pan and stiffening ribs. This roof took about two weeks to install between tear-off of old asphalt shingles, siding removal, replacement of rotten wood replacement, delays with material shipments and wrong type of flashing being delivered.

Actually one of the delays happened because our supplier ran out of Grey aluminum coil after 80 % of roofing panels were rolled out of their mobile standing seam roll-forming machine, which was based in Manchester, NH. As the supplier received more aluminum coil 3 dais later the send a different truck, from New London, CT. As that truck arrived and rolled off the first test panel, just out of curiosity I decided to compare first batch to the second one. It turned out that the machine on the New London truck was set up to be 1/8″ wider than Manchester truck. This, over the course of 23 panels gave us an extra 3″ of panel which converted to two extra panels – 1 1/2″ wide – on either side of the rear roof section and exactly 23 panels on the front. We had to send the truck back and wait for the Manchester, NH truck to deliver and roll out the same coil. Even the guys working for the supplier were not aware if this mismatch between the two machines.

In the end the Manchester truck delivered the right-width panels and we were able to finish the jobs without any more delays. The homeowner – Glenn – was also very concerned with snow and ice falling off the roof and damaging the gutters bellow, so we installed a commercial-grade double rail snow retention system to eliminate the possibility of snow falls form the roof.

We already posted a full review of this roof installation on our blog, a few months back, so if you want to know more details, read the standing seam metal roof in Wayland, MA job profile.

Rubber roof in Boston, MA.

In August of 2009 we’ve completed a rather small, but very tricky and complicated flat roof installation in Boston, on one of the traditional Boston-style homes/buildings, which you can see all alogn Mass. ave, Comm. ave as well as Blue Hills avenue, on which this house is located. It was originally a EPDM rubber roof, which had over 50 percent of seams separated due to adhesive failure. The two-tower wood design made this roof much more difficult to repair and our client – Jim – chose to eliminate the hassles of frequent roof repairs and decided to have an 80-mil IB roof installed.

Although this should have been a pretty much straight-forward roof replacement, with rubber tear-off performed first and a new IB roof installed, I sensed that it will not be an easy job. Until we opened up the roof I could not say for sure what obstacles we’re going to face, but once we did remove the rubber, we found that entire length of the masonry parapet wall was damaged by water and poor quality of brick mortar. We also found that we would have to rebuild the parapet walls much as 4 layers of brick deep.

Because a chose a careful approach to the rubber removal, by only pulling back the rubber membrane off the parapet wall, and not cutting it, we were able to do entire brick repair work and roof preparation, while having the roof watertight each night with original rubber membrane.

Once all brick repair war was complete and mortar had sufficient time to cure, we installed a 2×8 pressure treated perimeter wood nailer to which IB wall flashing and drip edge would be attached. Only on the last day did we remove the whole rubber roof, installed new insulation and laid dawn the new, mechanically attached IB PVC flat roofing membrane.

We had to come back one more time to install the new gutter and downspouts, IB two-way membrane vents and 9″ IB attic vents over specially cut holes in the roof deck. These attic vents were installed to vent out the moisture that accumulated in the small attic space when the old rubber roof was leaking. Once in place these oversize vents will eventually dry out the attic and prevent any future mold growth.

Now Jim can enjoy his watertight roof and get sun baths sitting in his beach chair on the roof of his home, and not worry about damage to membrane – he chose a very durable, commercial grade 80-mil IB roof. He will also enjoy a cooler home, due to IB cool roofing features.

Flat roof in Framingham, MA

One of the more recent roofs we’ve installed was in Framingham, MA, where we installed an IB roof on yet another shed dormer roof for Ed Kelly – a high-end remodeling contractor out of Northborough, MA. The builder had his crew remove old asphalt shingles off this roof an replace most of the old decking with new 3/4" plywood. We were there to install just the membrane and flash it 2 feet up the sloped roof.

During my conversation with Ed (builder), he told me me why he chose the seemingly more expensive IB roof over a cheaper rubber EPDM membrane. His main reason was the IB’s hot-air welded seams, and hassle free roof performance. Before, Ed would use a rubber roof on a few of his projects, end all but one of them leaked due to problems with seams, and required expensive rubber roof repair. Ed decided to end his flat roofing nightmares and constant rubber roof leaks, and went with IB roof.

The entire job took us one day to complete. The roof was ready to start, as we arrived to the job site in the morning, and before dark we packed our tools and were ready to leave, as the roof was all done. The roofing crew which did the tear off and deck replacement was putting the new asphalt shingles and aluminum fascia trim back on, as we were driving away.

Roofing material: 50 mil white IB roof, mechanically attached.

Insulation: 1/2″ fan-fold Styrofoam.

Total roof size: Approximately 450 sq. ft.

Flat roof deck in Wellesley, MA

Just before the Framingham flat roof job described above, we did another job for Ed – an 80 mil IB roof that would be a water-proofing membrane for a roof deck over a garage being built as an addition to an already huge home in a very secluded area of Wellesley.

Once again, a complete job profile for this roof deck is already on our blog, so there is no point to rewrite it here – read the Wellesley, MA  flat roof deck installation overview.

Solar flat roof in Medford, MA

This job, was actually sponsored by Cool Flat Roof (us) and IB Roof Systems, as it was a non-profit project, competing in the 2009 Solar Decathlon competition, sponsored by the US DOE. We installed an IB roof on a Boston solar home with some help from the project volunteers and Architecture students from BAC and Tufts.

Once again, we have a complete coverage of the installation of the IB flat roof and the Solar PV panels on this roof - Solar roof installation in Boston, MA.

Low slope shed dormer roof in Hingham, MA

Yet another shed dormer roof and also with major ice dams problems and leaks. This roof was just a year old when we removed the old asphalt shingled, and installed a new 50 mil IB traditions roof with asphalt shingles pattern printed onto IB white roofing membrane. This roof was completely covered with Ice & water shield which failed miserably and forced homeowner to climb up the slippery ladder all winter long, sometimes two times a day, to brake off the ace along the roof edge.

Homeowner – Paul – tried everything, from sodium-filled socks above the skylights to heating cables – nothing seemed to help, as with lack of proper ventilation and inherent limitations of asphalt shingles, his roof was still leaking, as it faced north, and sun never shined over it in the winter.

Paul wanted a permanent solution to stop roof leaks and not a single roofing contractor that Paul contacted could explain to him how they would stop the leaks or promise that their roof will work. Some even offered to  install asphalt shingles with Ice & Water shield – Really? Paul already had shingles with Ice and Water and it was not working.

Initially, Paul contacted us about getting a metal roof installed on his house, but after examining the roof, I suggested ti install IB roof instead, and residential flat roofing solution form IB  - Traditions Classic seemed to be the best option as it combined all the benefits of IB roof with the classic look of architectural asphalt shingles printed onto the membrane. After a little decision making, Paul and his wife chose to go with a seamless one piece IB roof. In this case there would be zero possibility of ice dam leaks.

All skylights now have seamless 1-piece plashing whelded to the roof, and the rodge vent is raise by an inch above the roof level to prevent wind driven water from penetrating the roof.

Now that Paul has a new IB Traditions roof, which is in effect a seamless, one piece blanket over entire roof, he and his wife won’t have to worry about roof leak and breaking ice off the roof any more.

With this, we conclude the first part of our Massachusetts job profiles list. We will update it as we have time to add more pictures and descriptions to each job, and will also add complete job profiles for each roof, when we have a chance.

Getting IB roof or a metal roof installed on your home in Massachusetts:

If your roof is leaking or you have Ice dams,and are tired of fighting with the ice, using heat cables, sodium-filled socks, raking your roof, and risking to fall of a ladder, you need to contact the low-slope roofing experts ( us ), request a free roofing price quote and schedule a roof inspection / estimate. You can also use our online roofing calculator to estimate your roof replacement cost and compare the roof prices of IB PVC membrane to Rubber roofing and Modified bitumen / Tar and gravel roofs.

Forewords: If you are a building inspector / official, please try to understand that this rant from contractors point of view… Or at least be objective and unbiased.

Pros and cons of building permits:

Why do we need building inspectors (and do we really need them)? Well, they are supposed to inspect – right? They are there to protect homeowners from shady contractors, and ensure that construction goes in accordance with state / national building codes. That’s why we also have specialty trade inspectors (electrical, plumbing, mechanical, etc). But do they really do their job? Another question – why do we need building permits? Yes, to pay the building inspector for doing his/her job – do the inspections. Yea, right!

I will purposely omit building inspectors in charge of large construction projects such as bridges, sky-scrapers, factories, etc. There is a lot more responsibility there and these inspectors are a lot more knowledgeable  than your average “Joe the building inspector”.

In my being a roofing contractor, I had to pull many permits in the last 6 years – for almost every job we did. In all this time, only once have I seen a building inspector at a job site, and he was there to harass the home-owner about the “illegal kitchen” that came with the house they just purchased. In the beginning of my construction life, I needed to get permits, but did not have sufficient / adequate insurance and in some cases did not have the Home Improvement Contractor registration in a state I was doing work. Luckily for me, I was able to get permits, and because I have dignity (I’d like to think so) I did decent work without code violations and nothing bad ever happened. I once had a “stop job” order posted at a job site, where we forgot to pull a permit. Ahh… the good old days.

When you get into serious contracting like the Metal Roofing and IB Roof installations, you can’t afford not to have proper insurances and licenses. Your clients by default expect everything to be current and you to be fully insured – both worker’s comp and general liability.  And besides, it is easier to show proof of insurance than to explain why you do not have it, or better yet to ask home owner to pull “owners permit”. It is also much easier to get a permit in 5 minutes instead of waiting 3 days and hoping that inspector is not a complete a$$ or is looking for a bribe – for some reason, I have a very strong suspicion that some building inspectors in Lynn, Revere, Malden and other surrounding towns in Massachusetts, purposely jerk contractors around, as if telling them – “give me $300 and you have your permit”. I really believe so. Or they just hate people in general. But let me get back to building inspectors.

My experience with building inspectors and permits:

I will try to be logical here, and present information in chronological order. Here is a work day of a building inspector as I see it:

In 85% of the times I walked into a building department of any city and town, building inspector is not there. Apparently they are out, doing inspections. But as I mentioned before, I had never seen and inspector on my job site, to inspect my roof. If inspector is in the office, he (I will use a “he” as all building inspectors I’ve met, were guys) will make you wait 2-5 minutes before asking you what you need. Apparently they need to feel as if they have power and are in control. After the initial coldness I did get permits, so there is nothing to complain about. But there is. And it is about how I got my permits and why do we actually need to pull them and pay for them. It is my honest belief that permits were instituted as means for towns to raise money, and biased on this assumption I’m more than happy to pay the fee. But any building inspector will tell you that permit is to pay for the inspection and enforcement on the building codes.

So I will tell you a few instances of how I got some of my permits, how horrendous the process can be for a contractor, and why so many contractors, including honest, illegal and shady ones, never pull permits. There is a provision in Mass. Building code that inspector has up to 30 days to issue the permit. We installed a Metal Roof on an IHOP restaurant in Hyannis, MA (down at the Cape Cod). When I vent to pull the permit (which was an hour drive one way) I almost got rejected, as my Worker’s Comp certificate was generic and not made out to Town of Barnstable. Fortunately, my insurance agent faxed in a copy 2 minutes before town hall closed.

As a side note, due to insurance fraud, in MA, your insurance agent cannot really give you an “all purpose” worker’s comp certificate, and the actual insurance company must print one out and mail it to you. This takes at least 3 days. Imagine a regular residential roofing company which installs a roof in one day and works 5 days a week. They have to get worker’s comp certificate for each roof, for every town they work in.

As my insurance certificate came out of fax machine, the office lady called over the building inspector to look at my paperwork (after being there for an hour and a half, he never looked a it). He asked me for HIC registration ONLY, although all commercial work required me having a CSL (construction supervisor license) and HIC implies that i do home improvement. When I offered the inspector my CSL, he said that he did not need it. Neither did he need my general liability insurance. Once he verified what he was looking for, he said: “You are all set – you can start in two weeks.” Why??? Why on earth do I have to wait two weeks??? I can loose a contract in two weeks. “Fortunately” half the roof on the restaurant was blown off by a storm wind, and it was more of an emergency roof work – this was the only reason he “allowed” us to start right away. So why do we need to wait two weeks I still don’t know. Time spent to get the permit – 4.5 hours.

Another time we did a roof in Grafton, MA. An IB low-slope roof on a residential home. Nothing fancy – a pretty straight forward roof. As I applied for the permit, I was told to firs fill out 7 different forms, pay three different departments for some ridiculous things (even the health department) and I also had to submit a SPEC for IB roof installation, including MSDS sheet (why?). They did not expect me to be back for a few days, but I was determined to either get a permit or permission to start work the same day as once again I drove pretty far to make sure every thing is ready for us to start when we planned to. I quickly ran to town library and printed about 20 pages of IB specifications describing exactly the parts of the roof we were going to do (I love IB online Quick Spec writer). When I brought back the whole package, the inspector was so surprised that he gave me an “ok” to start any time. Later, his secretary told me that he will actually read the spec. If I had know, I’d print out 200 pages, of exiting reading material.  Time spent to get the permit – 5 hours.

There are many other stories I can tell about pulling a building permit. I do want to say that not all inspectors are evil. One time we told a building inspector in Abington, MA that we did not have MA HIC – only the one from Rhode Island. He was cool enough to tell us: “get the homeowner to pull the permit”, which we did and all worked out well. I also absolutely love the Boston building department. The flow of contractors there is so heavy that they do not have time for stupid things like full spec for a small residential re-roof. They check your insurances and licenses, collect a fee and give you a permit.

Many towns in MA and CT will give you permission to start and mail you the permit. Some will make you run around as a squirrel. They will want 3 days before you can start a job. So I adopted and “evolved”.  Now I call the building department of any city or town where I’m going to work and tell them that I have a 3 hours drive to just get to their town, and if the could “please let me start the same day I apply for a permit”. This usually worked great. For example, when we installed an IB flat roof in Andover, CT – I never actually met the building inspector in person. I spoke to him on the phone – told him roof leaks and is covered with tarps (which was true) and we need to start ASAP. He gave an ok and all I had to do, was apply for the permit and provide proof of insurance and a construction license.

The second flat roof which we did in the Andover, CT – I still had to talk to him on the phone. This time he wasn’t as happy but since we already came to town, I “begged” him to let us start the job, without looking at it. Once again it was a complete tear-off and pretty straight forward, so he gave us a green light. But from now on, I have to apply for permit by mail and he wants to see my work. Next time I’m in Andover, I’ll give him a call ahead of time. Here you can see the pictures of our second roof in Andover, Connecticut and on of a roof in Westminster , MA: http://www.coolflatroof.com/flat-roofing-blog/low-slope-roofing-on-shed-dormers/

Why you should have a building permit for any construction work:

Bottom line – not all building inspectors are evil. Some are very nice, some are just bored and need things to do, and some need to feel powerful. All depends on your luck. I learned how to coexist with any building inspector, and no do everything in advance – even have my insurance agent fax over my certificates before I arrive at city hall.

Why did I write all this? Well – this is my blog and I can do it! Where else can I talk about it?

What is the point of all of this? I just had to get it out of my system after years of contractor – inspector interaction. Also my friend tried to pull a roofing permit for a VERY simple and straight forward roof – a measly 9 squares  on walkable gable roof in Malden, MA. And the inspector wants to inspect … maybe he had a bad day, but my buddy has to wait a few days until he can start. Really? So this was my inspiration.

Also, I want to make a point that many inspectors let shady contractors with fake certificates slide through or don’t even check for insurance and construction license, all-the-while they make other contractors chase their tails and waste time (and money) as if they have nothing to do. They also harass homeowners and issue stupid fines for stupid violations that should be grandfathered in. This creates situations where homeowners  and contractors knowingly do not pull permits. It also creates risk for homeowners to be left out if a shady contractor does bad job and screws them – without a permit they cannot use the Mass. Homeowner Protection Fund.

Can this be fixed? I don’t see a solution since there are too many hack inspectors and contractors out there and homeowners really need to do their due diligence – check references, call people, look at the jobs, licenses, insurance certificates, etc.

I encourage any homeowner to read my article on how to choose a roofing contractor. You should also know that it is pretty easy to “scam” the building permit process. For example, a roofing contractor must have a full roofing general liability insurance, which can easily cost $10,000+ per year, and worker’s come which runs at about 35-40% of payroll ($35-40 for every $100 you pay your guys). Many contractors will buy a siding insurance for $500-700 per year and use that certificate to pull permits.  The can also claim to be “sole proprietor” on the Worker’s Comp form when they apply for a permit and get away with not having the insurance at all – even if they have employees.

As for licenses – in Rhode Island there is no construction license at all – only a contractor registration. You can do everything with it, except for electrical, plumbing, etc. In Massachusetts, only recently have they implemented a mandatory requirement for CSL to perform roofing, siding and windows work. Before, any hack could get a roofing permit with just and HIC registration.

So once again, always do your due diligence when choosing a contractor.

As for the contractors – have your paperwork ready, do good work and, good luck guys!

PS. I’m not an angel and did not start my roofing business with $20,000 to buy all proper insurance. I did my share of getting around the permitting issue. Every one goes through it, but some remain in that stage forever. As for me – I prefer to do everything the right way or not do it at all.

As I’m writing this, the 2009 Solar Decathlon in Washington, DC is nearing its completion. Twenty teams from around the globe are competing to build the best Solar Home, judged in ten different categories, including: architecture, engineering, net metering, living comfort as well as others. This year, Massachusetts – home to some of the  greatest colleges and universities in the world – is represented by Team Boston - the joined efforts of Tufts, Boston Architecture College and a team of volunteers, all with the common goal to create green and sustainable home designs that could be readily available and affordable for actual home buyers and home builders. You can read my 2009 Solar Decathlon Review with pictures and videos I took there during Columbus Day weekend.

Cool Flat Roofs and IB Roof Systems are proud sponsors of Team Boston’s solar home.  We provided the project with IB flat roofing materials (provided by IB Roof Systems) and a professional installation, as well as last minute roof design changes, and modifications to roof penetration placement and drainage setup.

The Boston solar home construction is all finished, the Solar Decathlon competition is almost over – the houses will be disassembled and and transported to their final placements. Team Boston solar home has already found its buyer in Cape Cod, where it will be available for public tours. Building this home was a bit less glamorous, and here I will tell you about our part – the installation of a flat roof.

Roof Design:

The roof was designed to allow for house to be transported in 3 sections, and to host 3 rows of solar panels, as well as collect all rain water. The house design team had to work really hard to make all three major requirements work together. The roof and the house were separated into 3 different sections, with separating parapet wall inside and around the perimeter. To avoid roof penetrations and as a result – roof leaks, the solar PV and hot-water racking systems had to be placed on top of parapet walls – both interior and exterior.

The roof drains and all roof penetrations had to be placed so they would be away from future solar system racking steel beams. The roof itself was designed so that all water in each section, would run toward the roof drain, with an overflow scuppers as back-up drains.

We utilized the 1/4″ (1/4″ rise to 1′ run) tapered insulation system, which would go from 1″ at the lowest spot to 5″ at the highest point. The roof drains were place at the lowest points of each roof section, while all roof penetrations were moved to the highest points on the roof.

Roofing Material: Because of multiple inside corners and roof penetrations, IB Flat Roofing PVC membrane was chosen and the best roofing system for the job, as it allows for all roof flashing components to be hot-air welded together, which eliminates a possibility of roof leaks due to seam failures. Even if the roof would be damaged during the construction process (there was constant foot traffic on the roof, after we finished installing it – plumbers, electricians and Solar PV installers), it would be easy to repair – as easy as welding a patch over damaged area – a one minute repair.

IB Flat Roof Installation – Day 1

Due to scheduling and timing matters, all construction on Boston Solar Home was performed on Fridays, Saturdays and Sundays of each week. We started installing our roof on a Sunday, after 2 days of rain, and as we pulled up to the construction site at Tufts in Medford, MA, it was still drizzling, and the team members were vacuuming and pushing water off the roof. This was a challenge by itself. After pulling the tarps off the roof, there were about 4 inches of rain water trapped between parapet walls of the roof and tightly sealed moisture resistant roof decking. Water was slowly dripping inside the house, but a major part of it was still on the roof. Two holes were drilled through the roof sheeting in the overhang section, where the roof drains would soon be installed. The water quickly drained over the grass, but a third section of the roof had to be manually cleared of water with a wet vac and push-brooms.

Installing Roof Insulation: As we unloaded our tools and materials, the guys from team Boston, were finishing the roof drying process, the drizzle stopped and we were ready to start installing roof insulation – a tapered insulation system that would span between 1.5 and 5 inches. We used different thickness ISO insulation board, starting with 1″ at the bottom, and going up / leveling it off with tapered and straight insulation. All insulation was attached with heavy duty, corrosion resistant screws and plates. At the highest point the R-value of the insulation would be 30-R (6-r value per 1 inch of insulation). Additionally, there are approximately 12 inches of sprayed foam insulation between the rafters, which makes the roof of this solar home, super insulated and eliminates the weakest point in the house, and when it comes to heat loss, as most heat escapes through the roof.

Installing IB Roofing Membrane: Due to weather conditions, we had to start work late, and it was apparent that we would not finish the whole roof in one day – even with the help of about 6 architecture students from BAC, and Tom Paisley – a green builder from Middleboro, MA, who introduced me to people from Team Boston.

We were able to finish one section of the roof completely, including all the parapet wall flashing and inside corner detail, installed a temporary roof drain, as well as welded all the seams. Since the plumbing for the IB U-flow drains was not in place yet, we installed IB membrane drain liner, and fitted it into a temporary PVC pipe. On the second section of the roof, we only had time to lay down the field sheets of membrane and a drain liner, and left the parapet wall flashing and corners for next day.

IB Flat Roof Installation – Day 2

As we arrived to the job site the next morning, the sun was beaming down on us, and the temperature was nearing 95 degrees – there was not even a sign of rain from previous days.  I was so happy that the roofs we install are white and barely gain any heat form the sun – otherwise it would be near impossible to work in these weather conditions. Nevertheless, I went through at least a gallon of water that day.

Architecture students and volunteers were laying down the insulation as I jumped onto the roof, and started planning out the membrane layout, to minimize waste. Since IB Roof comes in 6 feet wide rolls, and the width of the roof sections was about 9-10 feet, there would be 2-3 feet of material I had to cut off. We would cut it in half, and use it for parapet wall flashing.

Once all insulation was in place, we could finish installing the IB Roofing membrane and welding all the seams to make the roof completely watertight. In total we had to flash 12 inside corners (and later, as we were doing the overflow drains, we had to install 6 outside corner flashings), 3 through-roof IB U-flow drains and 4 through roof penetrations: 1 for the bathroom vent and 3 others for Solar PV and Solar Hot Water hook-ups.

All seams were welded with the Swiss made Liester hot-air welding equipment which is a de facto standard in the thermoplastic roofing world. For long seams we used the Liester Triac Drive – an ultra portable semi-automatic welder which can make a life of a roofer much easier. When we need to weld a small section of a seam, the hand welders are perfect. But when it comes to longer seams, doing it by hand become, if not problematic, then very painful - literally. Hand welding can put a lot of stress on your wrists and that is why we invested heavily into automatic welding equipment.

Solar Home Roof installation video: Welding IB roof seams

One major obstacle we still had to solve was the the fact that Solar Home is built to be transportable in 3 sections. The IB roof membrane would have to be cut along the inside parapet walls, to take the house apart, and when the house is put together, it would have to be watertight, and preferably without having a roofer and hot air welding equipment on site. Although the parapet walls would be copped with aluminum parapet caps, it would not be a sufficient way to keep the house watertight and leaks free – maybe just for a short period. But the team could not afford to have roof leaks in the middle of Solar Decathlon competition or after. We had to figure out a way for the roof to be watertight not once, but every time the house is transported and put in place, without additional welding. This we took care of later, once the Solar PV and Hot Water panels rack system was installed.

We finished day two of roof installation as it was getting dark, and most architecture students had already left the job-site. Now we had to wait until the solar panels were ready to be installed.

IB Roof with Solar PV and Solar Hot Water panels – Day 3

Once the IB roof was installed and Boston Solar Home was watertight, we took a little break and concentrated on our everyday roof installation. In this time, the Team Boston was hard at work on the interior of the house as well as getting ready for the final stage of the roof installation – Solar PV and Solar Hot Water installation, which would use a Steel / Aluminum Racking systems bolted to the parapet walls.

By the time we got to the job site on the 3rd day of roof installation, the mounting racks were already in place and some Solar PV panels were also installed. We had to work around them and in some cases actually move the racking system and Solar Panels, so we could get into tight spaces.

We had to install all three IB u-flow drains (which due to their size did not fit between the solar racking system), pipe penetration flashings for exhaust pipe and solar electrical and plumbing hook-ups. We also had to install the over-flow drain scuppers and as I discussed before, we had to figure out a way for the house to be watertight after it was transported to Washington, DC fro the Solar Decathlon and to its future owners, preferably without roofer involvement.

We decided to weld a wide strip of IB membrane over parapet walls – one side would be welded while the other would remain not welded, but flipped over to the other section. This way the cut between house sections would always be watertight and with the addition of parapet caps, the wind driven water would never penetrate the roof. W also had to figure out how the “T” join of 3 house sections would work, and the overlapping joint covers were installed, each welded to its own section of the house.

As we finished installing all roof flashings, the house was all watertight and almost ready for the transportation to the Solar Village in Washington DC, for 2009 Solar Decathlon. There was still a lot of work to be done, like all the heating, interior, and other construction work, but our part was over. I did plan to volunteer some of my time to help team Boston with building this beautiful home, but as the busiest time of the roofing season rolled on, I could harly find time for my full time job. I did not see the Boston Solar Home until I actually went to DC for the Solar Decathlon, during the Columbus Day weekend.

Quick highlights of the Boston Solar Home:

• Size – approximately 800 sq. ft. Competition regulations limit solar home size to 800 sq. ft. and most contenders, except one, built their homes to maximum allotted size.
• Solar PV system size: 6.4 KW DC, with individual mini inverters to maximize electric output, and minimize shading losses.
• Wall insulation: 2 inches (13-r)  of ISO board with aluminum foil (more insulating value than regular ISO board) and 8 inches of in-wall insulation.
• Trombe wall – a liquid-filled solar thermal mass windows, that collect and store solar heat during the day and heat the house at night.
• Solar Hot Water – 5 hot water panels that provide heating and hot water for the house.

Because of size limitations, each team had to use the most efficient solar panels available on the market (not development products). This posed additional obstacles for the designers and builders, and forced the use of rack-mounting system to house solar panels. If the house was not limited to certain size, the use of IB Solar Wise PV system – the building integrated solar PV modules built by Uni-Solar, would greatly reduce the final cost of solar system and simplify the installation. IB SolarWise eliminates the need to use a rack mounting system as it is a thin-film solar system adhered to IB patented membrane – Solar Shield – which distributed the heat gain of solar panels and prevents delamination,  which is often the case when UniSolar panels are installed over rubber roofs of TPO single ply roofing systems.

It is October, and the cold weather is upon us. Now most homeowners who did not have a chance to replace their leaking roofs during spring and summer, want to get it done now – before he cold weather arrives. August, September and October are the busiest months of the year for a roofing contractor (for us at least) we get many calls and online estimate requests from homeowners looking to install a new IB Flat Roof or a Metal Roof on their home. At least 75 percent of these inquiries, mention that they would like to have a new roof installed before the winter. While we do understand your concern about having a new roof before winter weather comes, I must point out a misconception among homeowners, assuming that a roof can only be installed during the warm months. While this is partially true, due to limitations of specific roof types (technologies), for us, installing our roof systems in the winter is the same as if it was summer – just a little colder.

Which roofs can be installed in the winter and which can’t:

As mentioned before, there are certain types of roofing systems that should not be installed in the winter, and also those that can, without any compromises in quality. Let’s look at them, but first I will divided them into two logical groups - flat roofs and sloped roofs. Also lets establish that by “winter” I mean temperatures bellow 40 degrees F.

Flat Roofs:

When it comes to flat roofing, there are virtually only two systems that can be safely installed in the winter – PVC and TPO. These two are thermoplastic single ply flat roofing products which are installed using the Hot Air Welded seams instead of various types of adhesives.

In the winter, glues and adhesives will freeze, which will distort it chemical composition in one way or another, which can and will cause premature failure. This is why most, if not all liquid roofing products (be it adhesives, or liquid-applied roofs such as acrylic or urethane coatings)  should not even be stored under 40 degree F temperatures – never mind being installed in cold weather.

PVC and TPO on the other hand are attached to the deck using mechanical assembly with heavy duty screws and plates, and all seams are sealed using Hot Air welding equipment which usually operates at 800-1100 degrees F. Such high temperatures ensure that even during cold winter months, all seam welds will not be affected by the outside temperature. I do have to mention though that PVC and TPO roofs are not equal or identical. They are only similar in how they look and installed. Besides that, PVC and TPO roofs are very much different and cannot be compared directly. I encourage you to read our PVC vs. TPO roof comparison.

Following flat roof systems should not (cannot) be installed in the winter:

- Rubber Roofs (EPDM)

- Modified Bitumen (cold applied or torch applied)

- Any type of Peal-n-Stick flat roofing products, such as GAF Liberty or similar.

The three roof types listed above represent some of the most common roofing systems available on the market today, with the exception of PVC and TPO single ply membrane flat roofs. The PVC and TPO did not not make the list above since the can easily be installed in the winter without and spec violations, or quality reductions. As for the rest of these systems, they are installed using adhesives (except torch applied Mod. Bit. roof) and therefore installing them in the winter will result in leaks and potential roof blow-off.

In example of Rubber roofs, entire system is usually installed with several different adhesives (one to glue rubber to the insulation, on for seams, special seam primers and cleaners, etc.) and EVERY rubber roof manufacturer explicitly points out that their roof should not be installed in temps bellow 40 degrees. I encourage you to read the following heated discussion on Roofing.com forums about flat roofing in frigid north where many contractors, including some from New England, will insist that Rubber can be installed in the winter, by pre-warming the glue and working when the sun is out, so it would warm up the black rubber membrane, for better adhesion. I also was talking to on of the sales reps for a big rubber roof “private label” distributor, who was telling me that winter months installation should be times perfectly – all glue applied between 10 am and 2 pm, only when the sun is out, and then the seams can be done between 2 and 5 pm, provided that all glues and primers are kept warm.  My take on it is following: Rubber roof manufacturers clearly state that such roofs should not be installed in less then 40 degree temperatures. Reps will encourage their contractors to install in the winter, because the make a sales commission and contractors will install because they need to stay busy, all the while violating installation specs. The only one at a disadvantage is you – the roof owner and here is why.

Because rubber roof installers have to go through so many additional hustles to install rubber in the winter, while they still have to charge their normal rates or even less, because competition is fierce and there is not enough work to go around, they will have to cut SO many corners to stay a bit profitable. Therefore, what you get is a roof that was installed outside of manufacturers specifications, frustrated roofers installing it, and and potentially frozen adhesives and glue which will most likely result in roof leaks, and warranty claims would likely be denied. Despite the fact that PVC is far superior to the above roof types, if you still choose to have a rubber roof installed (for financial reasons for example), do not do it in the winter.

Peal and Stick roofing systems and underlayment should not be installed in the winter for obvious reasons – they will not properly stick to the roof deck or base ply, making leaks or even blow-off almost certain. Such roofs should ONLY be installed during warmer months of the year.

Sloped Roofs:

When it comes to sloped roofs, the choices are many and very few at the same time. Basically you have asphalt shingles, metal roofing, and other very rare types of roofing material which usually cost at least as much as metal roofs or more. These are Slate roofs, Tile roofs, Synthetic slate, Cedar shingle or shakes and that is about it. Since asphalt shingle is the most used typo of roofing material (merely because it is the very cheapest roof you can find) rivaled by metal roofs on the premium side, I will only consider these two types for the comparison.

Asphalt shingles can be installed in the winter, but extreme care must be taken by roofers installing it, not to bend and crack the shingle as well as not to trap moisture under the shingles. Because of the reality of winter roofing, very often both of the above are ignored by roofers, causing premature roof failures. Also, because asphalt shingle roofs are highly dependent on the proper seal between the overlapping shingles, which requires the solar heat to melt the seal strip, such roofs installed in the winter, often do not seal properly until warm weather rolls around, causing them top leak, and as a result, wood rot often develops under a brand new roof.

Another major limitation of asphalt shingles is its weakness against Ice Dams. Ice and Water (I&W) shield is the most commonly used method to prevent ice dam leaks. First of all I&W fails about 25 percent the time, and because it  also requires sun’s heat to properly adhere to the roof deck, in the winter, moisture develops between roof sheeting and underside of ice & water underlayment potentially making it useless.

Metal Roofs on the other hand can easily be installed in the winter without any compromises in quality of installation. First of all, with metal roof it is actually absolutely not necessary, as metal roof sheds water and ice, minimizing ice build up on the roof. Also the interlocking design prevents water from traveling upward. All this renders the ice & water shield useless. At the same time it prevents the proper breathing (ventilation) of the roof deck which shortens its service life. And ultimate goal is that the roof deck lasts as long as the metal roof over it, which in the case of aluminum shingles is a very long time. Therefore, unless you or the building inspector want Ice & Water to be there, I think it is best not to put it on. We use a premium breathable synthetic underlayment – GAF DeckShiled which makes the roof watertight even without a metal roof over it, and helps the wood “breath”.

Cold weather also does not affect metal roofs as they won’t crack due to “improper handling” and metal roofs are designed to allow for expansion and contraction, so the outside temperatures won’t make a difference.

As you can see, IB PVC roofs and Metal roofing systems are the best system to have installed, year round!

We constantly update these pages, adding jobs we’ve done recently and those that were done some time ago. It is a slow process as we try to describe each job in as many details, and point out certain common roofing problems and how we overcome them. Soon we will add roofs that we have completed in Rhode Island and New Hampshire, as well as more MA and CT roofing jobs.

Some Massachusetts and Connecticut roofs we’ve installed in the winter:

Flat roof in Lowell, MA – one of the most recent roofs, installed in the beginning of Dec. 2009. Here we removed old epdm rubber roof, which shrunk and pulled away from the walls and roof edges. We replaced this roof with new IB PVC flat roofing membrane, and added 4″ of ISO insulation to improve weather-tightness and energy efficiency of this home.

Flat roof in Andover, CT – this roof was installed in January 2009, right in the middle of brutal cold storm which overtook New England for almost two weeks, and temperatures reached as low as -16 degrees F. There, the homeowner, with help of his buddies, removed the old roof, and fixed the roof deck, and covered the roof with a tarp. We had to quickly come in and install a new 50-mil IB roof, right before another snow storm hit.

Metal Roof in Brighton, MA – an new aluminum shingles metal roof was installed on a roof of a very busy IHOP restaurant, while it was open for business. This large roofing project involved complete removal and replacement of old metal shingles, all plywood decking, which was mostly rotted, replacement of some rafters and installation for new GAF Deck Armor underlayment and a new metal roof. Due to many major snow storms during that winter, this project took almost two month to complete. About same time 2 years ago we also installed another metal roof on an IHOP restaurant in Hyannis, Massachusetts.

Rubber roofing (EPDM) is not the best system for flat roofs, but in some instances, it just does not work right off the bet, and when it leaks, repairing such a roof is not even an option. In late July of 2009 we began work on one such roof in Roxbury , MA – a neighborhood of Boston, located 15 minutes from downtown.

The roof was installed by an unqualified roofing contractor that apperanly never installed a rubber roof before, nor did the contractor care about quality at all, which you can judge for yourself from the photographs of the roof that we’ve provided. As you will be able to see, this particular roof, though small, required a lot of detail work which is the defining factor of weather this roof will leak or not. The roofer that installed the EPDM rubber on this roof, completely skipped the flashing part, choosing to instead caulk the corners with rubber lap sealants, and in some cases use the sealant to adhere membrane seams. As a result, most seams – even those that were glued together with rubber glue, partially or completely came apart.

In addition to a generally horrible roof installation practice used by the contractor, the home owner – Jim  - was very concerned about insulation screws being loose under the rubber roof and in some places penetrating the roof, cratering more leaks. Despite all the corner cutting and improper installation of the rubber roof, Jim had one advantage that kept his house more or less watertight, and without major roof leaks. The roof was built with a slight slope, which diverted all the water toward the through wall drain, while parapet walls kept the water from spilling over the roof edges.

Just as a side note, this house used to be a part of a larger building, which was partially demolished at some point in time. Its back wall now, used to be a separation firewall between different sections of the building. You can easily figure it out by looking a the brick on the front and back of the house. This brings up a mystery which I cannot solve: The through-wall drain is located in the back of the house where the old separation wall is now. Therefore, back when the house was bigger, all the water would flow to the adjacent section of the roof. Still it had to drain somewhere, otherwise the house would be completely flooded, and a roof could actually collapse under all that weight. I suppose there were through-roof drains which were buried / removed during one of the re-roofs and a through-wall drain was created when rear part of the building was removed. I will come back to this topic later on, when I’ll discuss the parapet walls on this house.

General roof details:

This was actually a very small roof (just over 400 sq. ft), which however took us more than 7 working days to complete. Most of this time was spent on preparation work and many repairs we had to perform, before the new 80-mil IB PVC flat roof membrane would go on. All these repairs had to be performed while maintaining roof water-tightness. Using tarps on this roof would be nearly impossible and time consuming to put up, because of the roofs shape. The roof has two round towers on the front, a “head-house” or a stairs walk out that leads to the roof in the center and parapet walls all around. In addition to all the given obstacles, to perform a quality roof installation we had to remove all siding and the door off the head house, and then put it all back together when roof was complete.

Roof installation – Day 0ne:

On the first day of roof installation was more like a test run, and we got rained out in the middle of the day. We started out the installation by removing the drip edge from the parapet walls and pulling back the rubber membrane to expose parapet walls. The reason for not just cutting rubber at the base of the roof and actually puling int back was discussed earlier – we had to keep roof watertight when we leave for the night and by maintaining a the old rubber intact, we could simply put back the flaps and attach them back to parapets, until we come back the next day. We also planned to install a 2×8 pressure treated (PT) wood nailer over the parapet walls, by attaching them with masonry anchors, and Liquid Nails adhesive (for additional rigidity). To our disappointment, over entire length of the parapet wall, the bricks were completely loose. Old mortar fell apart, damaged by age, moisture and other weather-related factors.

Between days 1 and 2 which were Friday and Monday, we went to install an IB roof that we sponsored for a Team Boston Solar Decathlon home with Solar PV roof. Since all construction on the Solar Home happened over weekend and the house needed a roof, to allow the crew to start work on the inside, we had to work all weekend to put on a new roof with a tapered insulation system.

The next day (Monday) we were back on the job site continuing work on the parapet wall repair.

As we dug deeper, it turned out that we had to replace at least 3 rows of brick mortar. We could not go any lower as that would create potentially disastrous situation with the old casted metals moldings installed on the outside of the parapets. This metal moldings were held in place by nails inserted into the brick joints. If we would remove another row of bricks, the metal would just come loose and fall to the ground in one piece. Fortunately as we dug deeper, the strength of mortar improved and we did not have to go down any more. Once the old brick was removed and old mortar, dirt / dust and other loose debris were vacuumed out, we could begin putting new mortar and bricks back. We had to wash and wire brush every brick, before it was laid back into the parapet wall. If you ask why not use new bricks – answer is very simple. The new bricks that you get from Home Depot or Lowe’s are junk. I could break on apart with my hands. Old bricks were of the exceptional quality and strength, and were solid brick (no cavities) which allowed us to securely attach masonry anchors later on in the roof installation.

Roof installation – days 2 through 5: brick work on parapet walls:

While maintaining rubber roof integrity, we replaced / repaired top 3 rows of brick parapet walls and performed all other prep work, while getting ready for the big push – complete removal of all rubber roofing and laying a new 80-mil IB PVC flat roofing system. The entire process had to be done in one day, so everything had to be ready. We removed old metal flashing, installed all wood nailer boards, membrane over parapet walls and drip edge before tearing off old rubber roof. Now the roof was ready.

At the end of day 5 we took down all th metal coping off the outside of the parapet walls. At this point it was dangerously hanging, nailed through the brick joints. One person would stand on the ground, making sure there were no pedestrians walking near the house while I was cutting the metal coping and taking it down in small sections. When all the metal was successfully removed, I was no longer worried that it may fall off on its own. Although we attached it to the rubber membrane over night with no chance of becoming loose, I still could not wait until the metal was completely removed.

Roof installation – days 6 & 7: installing IB roof and welding seams

Once everything was prepared, the actual roof installation took two days. First we laid down and mechanically attached all the membrane. All field seams were welded before any flashing work began. Once main membrane was installed we flipped down all the membrane that was already installed on parapets and welded it down to the main roof. Then the roof to wall flashing on the head house was installed, and it was now time to flash the chimney and at the same time make a new through-wall drain liner, so the water would run off the roof into the gutter which we later installed along the back wall of the house.

At the end of day 7, all roof flashing was welded together, roof attic vents and membrane vents installed, the door was put back on the roof entrance and everything was watertight. All we had to do now is to come back one more time to install the new commercial 6″ gutter and 4×3″ downspouts.

Although this roof took twice as long as originally planed, we had enough time to fix everything and get the roof ready and now it will perform flawlessly, protecting this house from water and reducing the inside temperatures in the summer, thanks to roof’s cool white surface.

Here is what Jim (the homeowner) has to say:

Hi Leo,

I’m writing to pass on my thanks. The new IB roof is a vast improvement over the poorly installed rubber one that preceded it. It was also a great idea to swap in some of the heavier IB for the main floor area. I can tell how solid and rugged it is.

I can also confirm that it’s working, believe it or not. There was a section of wall in the upstairs hallway which had gotten damp, to the point that paint had begun to peel there. I’m likely going to replace the sheet-rock at that spot anyway, to be safe. But it is now bone-dry! We’ll see how it goes, but it seems to be off to a promising start.

I much appreciate the thoroughness and quality of your worksmanship, and that of your crew.

All the Best,
Jim

This will be project profile of a flat roofing system installed over a sun-room roof in Wellesley, Massachusetts. The roof system was planned in such a way that a premium wooden deck would be installed over it, and the long-lasting water-tightness was most important aspect, and the the same time aesthetics were also important.

Waterproofing a flat roof deck:

Wellesley is know for its beautiful mansions and only the best building products (such as IB Flat roof) make their way into these homes. Having a backyard deck is a great addition to the cosiness of any home, and very often such decks are built over a sun room, garage, or other living space. Therefore, having such deck completely watertight is of utmost importance. If this flat roof deck leaks, it would be very difficult to trace a leak as a wooden deck siting on slippers over the waterproofing layer is usually built as one piece and it would require a complete dis-assembly of the deck to find and fix the roof leak.

Railing systems on flat roof decks:

Each deck must have a railing system. For aesthetic and structural reasons, it is best to install the railing posts through the roof and tie them into roof rafters, rather than attach them to the outside perimeter of the deck. However to make these through the roof posts watertight using conventional flat roofing systems such as rubber roof, is nearly impossible in the long run.

Why IB Roof is perfect waterproofing system for flat roof decks:

Because of such high demands to the roofing material to be watertight and long lasting, IB Flat Roof was chosen as the product of choice for this high end residential home in a secluded neighborhood of Wellesley, MA. While this home was going through a complete renovation, a large addition was built in the rear of the House including a beautiful sun roof, and a beautiful premium wooden deck will be built on top of an 80-mil commercial grade PVC roofing membrane.

Installation:

When the general contractor was building this garage with plans to have a deck over flat roof, one of the major concerns was to drain water off the roof and avoid any ponding water. Having a through roof drain was not very practical as the roof would be divided into 16 sections by the deck slippers and most of the water would never get to the drain. Therefore, the roof framing was built with a slight slope away from the house.  Although this could be achieved with tapered insulation, it is always better to have the framing with a slight slope, especially if there is a rubber roof which can leak and saturated insulation would settle under the wight of the roof deck.

When planning the installation of this roof, we had to take into consideration such factors as deck slippers running across the roof every 16″ O.C., eight through roof railing posts around the perimeter, and a slider door leading onto the deck. Most flat roofs that we install are mechanically attached, using heavy duty roofing screws and barbed steel plates. During the roof installation we had to make sure that all our plates and fasteners holding down the insulation and the roofing membrane, would be place between the slippers laying directly on the roof, to prevent the fastener rubbing through the IB membrane and creating a leak.

We marked the spots where the slippers would run along the wall and the drip edge, and using a chalk line, place all fasteners between the slippers. Additionally, once the roof was complete, we installed 2″ wide strips of membrane, tap-welded in place. These strips will be additional separation layer to protect the membrane from the deck slippers rubbing against it.

To make sure there are as little welds (membrane seams put together using fusion hot-air welding process) we aligned the first 6′ wide sheet of the membrane with the rail posts, pre-cut the holes in the membrane and slid the membrane over the posts. Next two sheets were aligned the same way and attached to the roof. Once in place, the membrane was welded to the custom made 3″ wide PVC coated drip edge, that was made in Bronze color. All Seams were welded across the roof, and now it was time to install roof to wall and pre-manufactured one piece post flashings.

Post flashings for deck roofs:

A quick work about these post flashings - as any other penetration flashing that is a part of IB Roof system, the postflashings are made in the controlled environment to the installer’s specs, to fit tightly around the post and eliminate potential installation errors of in-field flashing using non-reinforced flashing membrane. All we have to do with theseflashings is slide them over the past and weld the flap to the roof. That is it – the post is completely watertight. Although the pre-made post flashing costs more than just non-reinforced material, the time saved during the installation and zero chance of a leak, after a proper installation, make it a much more economical way to permanent watertight roof deck with trough roof posts.

In conclusion, I would also mention that there is an alternative to having to build a deck over flat roof – it is IB Deck-Shield, which works just like any other IB roof, but is designed to be slip and puncture resistant and allows you to walk over it just like as if it was a wooden deck.

Recently we finished installing an aluminum standing seam metal on a residential home in Wayland, Massachusetts. The roof is made of .032 Aluminum, coated with grey finish Kynar 500 coating. It is a 1.5″ snap-lock standing seam, attached with stainless steel clips and wood screws. Also, as you can see, there is a rail snow retention system which I will describe in detail bellow. It consists of cast-aluminum mounts attached to ribs of the standing seams roof and two rows stainless steel cross bars (rails) to hold snow and ice from sliding off the roof.

Originally, the homeowner was having bad problems with Ice dams and roof leaks. Originally roof had “ice belt” made of copper, but it only covered the bottom 2 feet of the roof and as we discovered later, during a roof tear-off, it was tucked under the shingles above it by only 2-3 inches. Needles to say, this copper ice-belt did not work as it was intended to and the ice dams were still creating leaks. After a while, to solve the Ice Dams, home owner installed large sheets of aluminum.

These were new and improved ice belt sheets, and Ice dams were no longer as bad of a problem. But now, after each winter storm, snow would accumulate on the roof, and as the heat from the attic (which was the original cause of Ice dams) heated and melded snow, which then re-froze, large pieces of Ice and Snow would avalanche off the roof, taking down the gutters with them. This was also a serious safety hazard for people living in the house and those visiting it in the winter. Home owner – Glenn – attempted to solve this problem by attaching improvised snow guards to the sheets of aluminum, but those came down after the next snow storm, together with Ice and Snow that accumulated on the roof.

After a few winters of cleaning snow off the roof, after each snow storm and fixing gutters after each winter season, Glenn was ready for a new roof. He was looking for a permanent, maintenance free roof that would be water tight, would not be affected by ice dams and a snow retention system that would prevent all the ice and snow from sliding off the upper portion of this gambler roof, and taking down the gutter system with it.

The roof:

As mentioned before, the new roof had to be maintenance free, resistance to ice dams, last a  very long time and to prevent snow and ice from falling off. Basically, functionality was the main concern for Glenn, yet a good curb appeal was also important. A standing seam metal roofing system system with energy efficient Cool Roof coating was chosen. Standing seam has no horizontal seams, thus a there would be no water back ups (which are a common problem related to ice dams on asphalt shingle roofs), and would would just run off the roof panels.

Stifening ribs were added to roof panels for additional rigidity and to minimize oil-canning that is common to to long standing seam panels.

Obstacles and challenges:

Although the roof is considered walkable and may seem easy from at first, there were numerous challenges we had to overcome during the installation and it is best to foresee these challenge beforehand, so they don’t pop-up unexpectedly during, and cause installation delays, and possible change orders (those unexpected charges that many contractors bring to the homeowner in the middle of the job). Despite predicting most of those obstacles during the initial roof inspection, I still missed a few minor things, which we took care of without having to have the uncomfortable “change order” conversation.

Main thing that came up during initial roof inspection was the fact that we could not install properly install roof to wall flashing around dormers, unless we pulled off the aluminum siding. At the same time we could not pull off the siding without damaging it, therefore it was decided to install new vinyl siding instead of old aluminum.

Another challenge would be the actual roof-to-wall flashing around dormers. Because of very steep slope on the lower part of the gambler roof, the angle bottom angle of roof to wall flashing was almost 140 degrees, and because of added height of 1.5″ ribs, these flashings would take a very long time to be done.

Installation of standing seam metal roof:

While we were waiting for the metal roof panels to be produced by our supplier, we had to remove old roofing shingles down to the deck. Installing a standing seam metal roof over asphalt shingles is just wrong, although some roofing contractors up in NH, ME and VT do it all the time and with steel panel too. Problem with doing that is such that shingles will punch horizontal lines in the metal roof panels, making it look ver unattractive. Second, and more serious problem is that granules in the asphalts shingles will rub against the underside of the metal panel, eventually scratching off the galvanic coating and causing the metal to rust in  multiple places. This would not be a problem for aluminum standing seam panels, but roofer that would install standing seam over shingles just don’t use aluminum as it is considerably more expensive for them and extra inventory would just sit unneeded.

Additionally, after removing the old roof down to the deck, we were able to replace any rotten wood that would otherwise be covered over with a lifetime metal roof.

Once the old asphalt shingles were removed and all rotten rood replaced, it was time for the underlayment. Underlayment is an essential part of a metal roof and also it will protect the roof, until metal roofng panels are installed. Because those are not always available to you right away – as was the case for us and we had to wait 2 weeks for panels to be made – the underlayment must keep the roof completely watertight until the metal roof installation is complete.

Because of such high requirements for the underlayment, we use exclusively and religiously the only underlayment that we find to work for us – GAF DeckArmor. It is a breathable synthetic underlayment ate is very strong, slip resistant, light-weight and make working with it a pleasure (unlike tar paper and other synthetic underlayments). Also, a very important factor for us is the breath-ability. It allows the moisture trapped between roof deck and underlayment to pass through and to run off the upper site of Deck-Armor, instead of creating rot and mold in the attic. This extends the life of wooden roof deck considerably, and is an integral component of the metal roofs we install.

Once all the prep war is done, the actual roof installation goes somewhat fast. There is a common confusion that I find among people contacting us about a metal roof. For some reason, most people thing standing seam roof is easy to install. This is actually very far from being true. Unless the roof is a straight run without any penetrations or obstacles, the standing seam roof take the longest to install with considerable waste if there are valleys and hips involved.

Because any penetration or flashing requires cutting the panel and using a z-bar, details take double the time that it would take if we were installing and aluminum metal shingles roof. Also, unless roof is relatively low pitch (3 or 4) it is nearly impossible to walk on panels and putting up staging such as roof jacks is out of the question. Fortunately this roof was low slope at the top, and bottom we were able to install off ladders – just like siding.

As I mentioned in the beginning, that falling snow and ice was on of the main issues we had to address and we had to get a heavy-duty snow retention system – the E-Rail for Berger Roofing Accessories.

Once the snow guards were in place, we could finish installing the chimney flashing, remove the fall protection systems and install ridge caps. Roof installation was complete and now the Ice Dams, rain and falling snow are not a problem any more for this residential home in the beautiful Wayland, Massachusetts.

Rubber roofing is a popular choice for low slope and flat roof construction, because relatively inexpensive, and “does not require any special training” on the part of roofing contractor, to be able to offer it to the customer and install. Do understand  that actual installation of rubber roofs is somewhat complicated and requires experience with flat roofing to install it correctly. However anyone can buy rubber roof form a roofing supplier and install it, without being certified by the manufacturer. Discover how many residential roofing contractors “learn” to install a rubber roof, nature and limitations of EPDM roofing membrane and why we recommend that you avoid putting rubber roof on your house. Since manufacturer’s certification is not required, many roofing contractors with little or zero experience in flat roofing, can and do install rubber roofs. However, without contractor’s proper installation training training and experience, such roofs begin to leak very soon after being installed. Discover the secrets of residential flat roofing market and contractors installing EPDM membrane or simply rubber roofing.

Repair yourself or hire a professional?

As a home or small business owner you should understand that to perform a repair of your rubber roof you will need to buy special supplies needed for the repair and allocate at least 3-4 hours on a sunny or at least dry day, with no rain in the next 12 hours, to allow the repaired patch or seam to cure and become watertight. Here is a list of supplies and approximate prices you can expect to pay to acquire these supplies form a commercial roofing supplier such as ABC Supply, Beacon Supply, Bradco or Harvey Building Products. Your local Home Depot or Lowe’s will not have rubber roofing so don’t waste your time there.

• Black Glue – $35-40 / Gallon
• Membrane Cleaner – $25 / Gallon
• Rubber Primer – $29 / Gallon
• 50′ x 6″ roll of peel & stick  FLASHING tape (uncured)  - $109
• 100′ x 6″ roll of  peel & stick cover tape – $179
• 100′ x 3″ roll of seam tape – $79
• 2″ silicon or steel roller – $25-45
• Tube of seam caulking (30 ln. ft. coverage) – $9.50

These supplies are ONLY sold in “contractor” quantities, and you cannot buy 10 feet of tape or 1 quart of Rubber primer. The list above is a minimum quantity you can purchase. As you can see, you will easily spend $200-300 just on supplies and you will also need a ladder and ofcourse your time (usually a weekend). Hire us to fix your rubber roof in MA, CT and RI: If you do not feel confident that you can fix your rubber roof or lack certain equipment, or do not want to purchase supplies that you will never use again, you can call us 1-888-6-Flat-Roof (888-635-2876) or fill out our online rubber roof repair request form. Here is how we charge for rubber roof repair. The service call fee is $350 and includes up-to 50-mile drive (one way) and an hour of repair work. We provide the supplies such as peel-n-stick tape and cleaners and adhesives, etc. Each additional hour is $95. Usually a small to medium repair is done in one or two hours. So for $445 (two hour of on-the roof repair work) you will have your roof professionally repaired, won’t waste your entire weekend and will not end-up with unused, unusable, non-returnable materials and supplies, while still wandering if your did the repair correctly. If you still want to do the repair yourself, keep on reading.

DIY how-to guide to repair rubber roof:

The default rubber roof installation method of 1970’s-1990’s and that of today’s shady roofing contractors looking to save every penny, instead of providing quality products and workmanship, is using Black Glue instead of peel-and-stick membrane tape. While black glue was in wide-spread use a decade ago as it was the only way to seal the rubber seams, it has been replaced by more efficient way, using seam tapes with peel and stick surface, which is activated by rubber primer, and creates a much better bond than a black glue can. This guide will describe how-to procedures to fix seams and flashing using Peel & Stick tape – both cured and uncured/flashing tape. To learn how to repair your roof using less expensive (and less reliable) black glue method, refer to our original rubber roof repair guide.

Tools you will need:

Seam probe, silicone / steel roller, scissors, clean rags, sharp utility knife, ladder to get on a roof, broom to clean loose dirt off the roof and squeejee with a body of warm water.

Finding the roof leak:

Flat roofs usually leak where there is ponding water, through the seams or near a roof penetration.

I assume that you have already purchased needed tools, accessories and membrane cleaned + primer, etc., and are now ready to  identified where the leaks are, using a probe tool or a nail. Step one – Clean the roof: Using a wide semi-soft broom, clean the roof of large pieces of debris. Use a water hose to wash other loose debris and dirt off the roof – this will help to soak the dirt and it will come off easier. Wipe the roof dry with a squeegee. Note: You do not need to wash the entire roof. Just the low spots where there is biggest chance to find a leak. You can also use soft wet cloth to soak and wipe clean the seams, so you could test them with a probe. There is a good chance that you can find a break in the seam without using a probe tool – these are usually very obvious. Step two – open up the seams: Assuming that you’ve found a leak that is coming through the seam,stick your probe in gently, making sure not to damage the rubber. Pull the seam apart about a foot in each direction from the spot suspected to leak. Make sure that there won’t be any rain coming soon, otherwise you may not have enough time to seal the roof.

If your seams are not very long – 20 0r 30 feet, it might make sense to open up entire seam and to seal it completely with seam tape, as this will greatly increase the effectiveness of your repair, rather than just doing 2-3 feet of seams.

Step three – clean the seams:

Using clean piece of cloth soaked with membrane cleaner, wipe both sides of the open seam, in and around it. Make sure u clean the edge of the seam opening. Make sure you get all the old glue off, before proceeding to the next step. Use something thin to get the cloth into the corners of two pieces of rubber membrane. Put a small block of wood inside the seam to let the cleaner dry. Once again, I will recommend to open up the entire seam to be able to better lean each side of overlapping rubber. This will allow you to get a better, continuous adhesion.

Step four – sealing the seam: If you opened the entire seam up (preferred method), brush on the rubber primer, making sure that it covers area wider that your seam tape – this will provide better adhesion, without any laps and lips. Put primer on both sides of the membrane.

If you only opened a couple of feet of seam, cut a piece of seam tape that is just about the same length as the opening. Using a paint brush, put generous amount of primer on both top and bottom lap of rubber membrane, making sure to get it all the way into the cracks of the seam.

Step 4.1 – installing seam tape:

After both sides of the seam laps are primed, starting at the end of the seam, unroll the seam tape, without removing the top paper. Try to be as straight as you can. It your tape starts to zig-zag left and right, it will create wrinkles and may pose a risk of leaks. Also your tape has to stick out from under the top lap, by about 3/8 of an inch, to ensure better adhesion. Make sure that it is not hidden under top lap, ans that also can create leaks down the road. you can use yellow chalk or special yellow pencil (sold at roofing supply warehouses) to mark the outer edge of the overlap plus 3/8″. Once you unroll the needed length of seam tape, fold over the top ply of the membrane and start removing the paper from upper side of seam tape.

If your seam tape is too short, and you need to splice two pieces of seam tape, overlap the my two inches, making sure that you prime both sides of each piece of seam tape before splicing (just the end 3-4 inches, as the res of the seam should already have primer). Once the needed length of seam tape is installed, flatten the top layer of the rubber membrane and roll it in, starting at one end and making sure not to miss a spot. Put some weight on that roller, but also don’t go too crazy. Too much rolling may make your wrist hurt.

Viola – your seam repair is complete! PS. Pictures used for this article were taken at a contractor training class on rubber roof installation, set up by Harvey Industries and RPI.

The word on the “roofing contractor street” is such that a large PVC roofing manufacturer has problems with their Roof-integrated Solar PV systems. Apparently, the way they designed and installed these solar roofs, the electrical wiring which  connects Solar PV panels to the inverter and essentially the Electric Grid, is overheating and poses serious risks of fire. Since this information is still in rumor stage, and I doubt there will be an official announcement or acknowledgment of these, I for many reasons cannot name the manufacturer, the specifics of the problems or the source. However, there is evidence that it is real. If you are a large roofing contractor in Boston, MA area or in the rest of New England, you are getting the roofing bid lists such as the Blue Book. We do not as large commercial and government roofing jobs are a little out of our league, and we get plenty of work without paying huge sums of money for these bid lists (it costs anywhere from $3000/year to get periodic updates). However, in the last 3 weeks I’ve been contacted twice by two different gentlemen from Suffolk Construction. Basically Suffolk is arguably the largest GC in Boston area with $1.57 Billion in sales in 2008, have over 800 employees and are rated #313 of America’s Largest Private Companies by Forbes.

The picture bellow, shows a Solar roof produced by IB roof systems. This roof does NOT have overheating problems, and is intended to demonstrate what Solar Roofing is.

In any case, the two gentlemen from Suffolk, asked me to bid a new job in the pipeline of roof bidding lists:  A 4,000 squares (400,000 sq. ft.) on the IRS building in Andover, MA, and also they wanted 500 KW solar PV system that would be roof integrated – essentially they were interested in out IB Solar Wise PV system which in some ways is similar to the one above, but without the wiring overheating of course The similarity is in the usage of the UniSolar Thin-Film PV laminates. Other than that, all other components of these Solar Roof systems are proprietary and are very different. So how are the two evens connected? It is my understanding that the Solar roof described above, was originally specified for this IRS roof, but because of the problems, they are looking for the one that works. Because IB SolarWise is about the only Solar Roof systems out there that does not have any problems with it, Suffolk contacted us on two occasions. Aside from the cable overheating and fire hazards, most other flat roofing manufacturers that wanted to use their roofs with UniSolar PV laminates, ran into problems of solar panels delaminating form the roofing membrane. IB Roofs took their time designing the IB SolarWise PV system, and developed a special membrane called IB Solar Shield which is designed to provide excellent adhesion between the PVC material use in IB roofs and the Butyl adhesive on the UniSolar pv laminates. This eliminates the potential of delamination that most (if not all) other roofing manufacturers are facing. The earlier version of IB SolarWise used the solar panels made by Open Energy of California. Later UniSolar panels were chosen as default integrated PV system because it allows for greater flexibility for the contractor, system designers and the customer.

Today’s IB SolarWise PV systems are made in the following way: IB takes 6×19′ Solar Shield membrane and placed 4 UniSolar 136 watt modules using a special process which insures the proper bond between two products. Then the whole IB Solar Wise module gets welded to the already installed IB Flat Roof. IB uses regular UniSolar modules with the connectors facing the outside of the module. Although this requires special housing to protect the connectors from UV rays, it eliminates the possibility of cable overheating as all wares are exposed to the air and are ventilated. This makes IB Solar Wise the best solar-integrated roofing PV system. If you are looking for more information about solar roofing in general or want to know if solar will work for you, we recommend that you read our Solar PV design & installation guide.

When a flat roof begins to leak, repairing it usually will get you about 3 months, after which it will leak again. This is especially true for roofs such as built-up tar and gravel, rolled asphalt or modified bitumen, because these roofs degrade with time, and start to leak because of material failure, seam adhesive breaking down, ponding water and in some cases, faulty roof installation. Hence, if possible, I recommend avoiding roof repair all together as it is in my opinion a waste of money in most cases.

Rubber roofs are different, and although the whole EPDM rubber roofing system is inherently flawed (IMHO) because it relies solely on adhesive (seam glue, primers, peel-and-stick tapes, etc.), the membrane itself will not break down for many years, so even if it begins to leak you can often salvage the roof by doing a roof repair, fixing the seams, installing new flashing at skylights, chimneys and other protrusions. With the recent move of EPDM roofing industry to peel and stick accessories, you can expect the seams to last at least a couple of years longer than older black glue seams.

We now offer rubber roof repair service in Massachusetts, Rhode Island & Connecticut

W understand that money can be tight and you want to get as much out of your roof as you can or maybe you do not want a new roof at all or just waiting unlit finances allow for it. Although we will never install a new rubber roof because we consider it to be inferior, we can professionally repair your existing rubber roof, at a reasonable cost and highest workmanship standards.

If you need to stop roof leaks now, and have a repair that will last, or want to get a some more time out of your rubber roof, until you are ready to have a new IB PVC roof installed, or just need a quick and inexpensive fix, we will professionally repair your rubber roof using the best materials, and will pay special attention to details, to make sure you get the best repair that will last.

If your roof is located anywhere in southern New England – Massachusetts, Connecticut or Rhode Island, we will come to you, inspect your roof and perform repairs during the first visit.

Here is how it works:

Our initial roof inspection includes looking for all the sources of leaks, identifying wet insulation, ponding water problems, rotten roof decking and most economical ways to fix your roof related problems. We will also perform a roof repair during the first visit, using only the best (yes, most expensive) rubber roof accessories such as Peel-and-Stick flashing, seam tape, Peel and Stick cover tape and will use if necessary, reinforced rubber membrane. We will not use the cheap, and outdated rubber flashings that are installed using black rubber glue (Rubber Seam Adhesive) unless it is necessary.

PLEASE NOTE: We do not want there to be any confusion about Peel-n-Stick rubber roofing accessories. Peel and Stick is better, lasts longer and costs about 3 time more than regular, non peel and stick accessories, which are installed with black rubber glue.

What we will do during our rubber roof repair visit:

• We will look for all possible sources of roof leaks – seam adhesive failures, flashing failures, ponding water, etc.
• We will perform up-to 1.5 hours of repair work using ONLY Peel and Stick flashings and accessories.
• If after 1.5 hours of roof repair work, there is more repairs to be done, we will identify problem areas to you and will give you a price to perform those repair. If agreed upon, we will continue with repair work, or will come back at your discretion.
• During roof repair, we will thoroughly clean the the area of repair using water and brush to get heavy dirt off, and then with Rubber Membrane cleaner to remove any carbon settlement and other contaminants that will prevent a proper adhesion of slashing membrane to the roof. We will not use gasoline to clean the repair area, as it is against the manufacturers requirements (although membrane cleaner costs about 10 times more than gasoline).
• We will identify thing that in our professional opinion need to be done to extend the service life of your roof, and will think of the lease expensive ways to do it.

Cost of roof repair:

The cost of initial visit, roof inspection and TWO hours of repair work is $350 if roof is located within a 50 miles form North Attleboro, MA. If your roof is located further than 50 miles from our office, we will charge an additional $50 for added travel.

Cost of additional repairs will be determined on site and you will get either verbal or written quote. If agree, we can either perform repairs while there or come back at a later time.

Warranty:

Because of variety of rubber membrane manufacturers, different age of rubber roofs and as a general industry practice, we (nor do any legit and reputable roofing contractor) do not warranty a roof repair. However, we will perform the repair service to the best of our ability, not only because we want your potential future business and value our reputation, but also as a homeowner, I personally know what it’s like to hire a bad contractor, and do not want my customers to experience it when doing business with us.

If you do  not live in MA, CT or RI, or want to try repairing your rubber roof yourself, we’ve created two detailed how-to guides:

1 – Our original Rubber roof repair guide that focuses on fixing a roof using rubber membrane adhesive (black glue).

2 – Our second EPDM rubber diy guide that is focused on using Peel-and-Stick flashing, seam tape and cover strip.

Additional information if you’re considering to fix the roof yourself:

While fixing the roof yourself may be a good choice if you are handy and want to save some money, the “save some money” part is what you need to consider.

All rubber roof accessories such as flashing tape, patches, seam tape, adhesive, membrane cleaner, rubber primer, etc., are sold in contractor quantities – usually 100 feet rolls, or 1 gallon cans, so if you need to just patch a skylight, you can easily spend 250-350 between all the tools (membrane roller, seam probe, etc.), shipping costs and so on. In the end you will be left with 95 feet of flashing material and nearly full cans of cleaner, primer and adhesive, which you won’t be able to return and probably will not need any time soon. At the same time, your firs repair has a high chance of leaking fairly soon because of lack of experience in fixing rubber roofs.

You may also purchase something that you will actually not need, or the wrong type of flashing as there so many choices. This happened to me a few time even considering that I am a roofer.

We now have a new, dedicated website that covers EPDM rubber roof repair ONLY – Massachusetts Rubber Roofing – there you will learn more about EPDM rubber roofing material, detailed DIY rubber roof repair guide, and complete EPDM roof installation how-to guide.
