Metal roofing is an excellent choice for quality-minded homeowners, because a metal roof is virtually the only lifetime roofing system that is light-weight, long-lasting, and most of all – affordable. If you compare prices of a metal roof to slate or clay tile prices, you will realize that an average metal roof will cost you only about one third the price of natural slate, while it will look the same or better, and last at least as long.

Beautiful, Durable and Long Lasting Metal Roofing – best roofing material for steep slope roofs!

There are many styles of metal roofs and many choices for roofing materials – your choices range from galvanized steel / aluminum metal roofs, to premium metals such as zinc, copper and stainless steel roofing. You can choose between a “standard” vertical panel (standing seam) metal roof, or a metal roof made to look like either cedar shingles, shakes, natural slate, or flat and barrel tile.

You will also get a wide range of colors to choose from. The result will be such that you will get the look you want with the price you can afford, and the long-lasting performance of metal roofing.

Metal roofing – premium roofing material at down to earth prices:

There is much confusion about the prices of metal roofs, as there is a wide range of metal roof styles and materials to choose form, with some costing a lot more than others. In this metal roofing prices guide, we will show you how much you should expect to pay for different metal roofing systems, and how the choice of metal roofing materials will affect your roofing cost. But before we jump into roof pricing for each type of metal roofs, let me clarify one thing: metal roofs are pricey as compared to asphalt shingles roofs, but keep in mind that metal roof is a lifetime roofing material and so should be compared to its counter-parts in the roofing market – other lifetime roofs, such as natural slate, clay Spanish tiles, concrete tiles, and lately, synthetic slate roofing.

How would you like to have an extra outdoor private space in your home to relax or entertain guests? A roof deck is an ideal option that will not only be enjoyable for years to come, but will also increase the value of your home.

Whether you are thinking of constructing a new roof deck or would like to improve the one you already have, it is essential for your deck to be leak free.

There are a number of issues that cause leaks in roof decks and a number of best practices that you can follow to keep leaks at bay.

Common leak causes and other issues with roof decks

One of the common reasons why roof decks leak is ponding water that forms on the roof. Ponding water occurs for a number of reasons such as inadequate roof drainage or roofing material failures. Most flat roofing materials, such as EPDM rubber, rely on adhesives to seal the seams and flashing around penetrations. Over time these adhesives break down and cause leaks. Ponding water further exacerbates this problem by increasing the rate at which seam adhesive fails. Read the rest of this entry »

Update – Oct 26, 2011: Exactly 2 years after the initial Sarnafil PVC Roof repair (read details below) I went back to that roof. This time there were 17 new holes in the roof. I repaired it once again with IB PVC flat roofing material. Check out the full review of this latest PVC roof repair in Needham MA, as well a overview of a DuraLast PVC roof that we repaired on a 22-story apartment complex in Cambridge MA.

Update 2: a Trocal roof repair also reviewed below – section of that roof has completely shattered over past winter, and we had replaced it with IB PVC Flat Roof in the spring of 2011.

Check out the video of this new PVC Roof repair:

Original PVC Roof repair article

PVC roofing is one of the longest lasting flat roof membrane systems, and most PVC roofs installed, will last in excess of 25-30 years. PVC roofing utilizes Hot-Air welding of the seams, which allows the roof to remain watertight for many years, as there is no adhesive to fail ( as is the case with EPDM rubber roofing ). Still, even PVC roofs can leak. Sometimes because of poor installation, and sometimes because of physical damage to the roofing membrane. You may have heard about the Trocal PVC roof failures, which was the only major case of PVC roof failures (below we will explain how Trocal roofs failed).

In this article we will discuss and demonstrate the PVC roof leaks and repair procedure, based on two recent repairs we have done. First, please note that even if your PVC roof leaks – you should not be too worried – PVC roofs are rather easy to repair, and you will rarely need to replace your entire roof.

What makes PVC roofing so “awesome”?

Awesome is a strong word to describe a roofing material, and yet that is what I think of PVC roofing. Although PVC is not the most durable (strong) flat roof, with hot air welded seams, you can install PVC on almost any roof, even if there is ponding water. Another great feature of PVC roofing (IB flat roof in this case, as PVC roofs from other manufacturers may not perform the same as IB roofs), is the fact that even after 30 years on the roof, the material is still flexible, and you can easily weld new material (such as a patch, or a flashing) to it. Also I should mention that most PVC membranes are compatible with each other, though if you use PVC materials from different manufacturers, or unapproved installer, you will probably void your warranty. At the same time, most TPO roofing membranes (which are similar to PVC roofs) will loose elasticity, and ability to be welded in as little as five years after installation.

Trocal PVC Roof Repair – West Hartford, CT – winter 2010.

As promised – a quick look into why Trocal PVC roofs failed on a massive scale, forcing the company to be sold to another large roofing materials manufacturer.

Trocal PVC roofing was one of the first commercially available PVC roofs in the US, and they worked great at first. But they had one major drawback – they were unreinforced (today, most PVC membranes are reinforced with polyester scrim sitting between the top and bottom ply of the membrane). When the ambient temperatures were below freezing, a Trocal roof could crack or shatter if you simply stepped on it, especially if it was really cold. Later, all PVC manufacturers switched to reinforced membrane, and some would add special chemicals to increase the elasticity of the membrane. Today, unreinforced PVC membrane is used only for flashing accessories such as inside / outside corners, pipe flashing, etc.

The repair of Trocal PVC Roof:

This Trocal roof sustained damage from a falling tree branch in December of 2009, and cracked along the edge. Although the roof was over 20 years old, it was still fully weldable and we were able to repair it with new IB PVC roofing membrane in Jan. 2010. We removed the damaged section of the roof, cleaned the surface with MEK solution, installed new PVC coated IB Drip Edge metal, and welded 50-mil white IB roofing membrane. The repair was performed in a 25 degrees outside temperature, so we had to take special care not to damage the rest of the original roof.

The term “green” has become very popular during the last decade and consequently overused, misused and abused. Anything and everything can be called “green” today. To make money and to attract environmentally-conscious customers, people will call themselves and their products “green”, even when it is just a blatant lie to confuse uneducated consumers. Being a roofing contractor, I will concentrate on roofing products and services. For example, many asphalt shingles manufacturers now offer “cool” and “green”  shingle products – to me it’s just a shameless tactic to sell the same NOT-GREEN crap that is painted A different color (usually some shade of white). Excuse me, but asphalts shingles are not green, period! TheY are made with asphalt, can’t be recycled and end up in landfills in 10-15 years.

Since the term green is very vague and can be interpreted in many ways, I’ll offer my vision of “green” – a green roofing contractor to be exact, which describes the way I think and try to operate our roofing business. I want to mention that when I say “green roofing contractor”, it has nothing to do with with a roofing contractor installing green roofs or roof-top gardens. To me a contractor installing roof-top vegetation is a highly-specialized landscaping company, but not a roofing contractor (unless they also install the actual flat roofing membrane to waterproof the building).

What is a “green” roofing contractor?

In my mind a green roofing contractor is a company that works hard to help protect environment and reduce its energy consumption and green-house gas production or carbon footprint. Sure, almost any company will have a carbon-footprint as it’s nearly impossible to be carbon-neutral, but there are many ways to achieve a much lower carbon footprint. Read the rest of this entry »

Foreword: If you are a building inspector / official, please try to understand that this rant is from a contractors point of view… Or at least try to 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 of doing 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 time 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 career as a contractor, 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 where 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 a home owner to pull “an owners permit”. It is also much easier to get a permit in 5 minutes instead of waiting 3 days and hoping that the 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 will have your permit”. I really believe so. Or they just hate people in general. But let me get back to building inspectors. Read the rest of this entry »

It is WINTER, 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 the 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 it is in the summer – just a little colder.

Basically, it is the best time for homeowners to have their roof installed during winter, as you will get the best roof prices, as well as a choice of the best roofing contractors, as work is limited and contractors compete for work and lower their prices to get the job. However, be aware that some roofs can’t or should not be installed in the winter – read bellow to find out what you should know about winter roofing, and which roofing materials should not be installed in the cold weather.

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 divide them into two categories - 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.

Rubber roofing is a popular choice for low slope and flat roof construction, because it is relatively inexpensive, and “does not require any special training” on the part of a roofing contractor to install it. Do understand that the actual installation of a rubber roof is somewhat complicated and requires experience with flat roofing if it is to be done correctly. However, anyone can buy a rubber roof from 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 a rubber roof on your house. Since a 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 a contractor’s proper installation training and experience, such roofs begin to leak very soon after being installed. Discover the secrets of the residential flat roofing market and how contractors installing EPDM membranes, or simply rubber roofing.

Repair a rubber roof 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 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 from 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. Read the rest of this entry »

Discover a permanent solution to low-slope roof leaks on shed dormers and other flat roofs.

Many homes in New England have shed dormers, which are build to use otherwise unusable space in the attic, and greatly expand square footage of the home, without huge expenses of building an addition. However, the way these shed dormers are built, requires them to have a very low sloped roof, at times almost flat. These roofs are the first to leak, as conventional roofing material cannot stand up to the Ice Dams build up and wind driven rain water, penetrating the roof between the seams in shingles and rolled roofing products.

The problem with shed dormer roofs is that often asphalt shingles or rolled roofing materials are used, and the seams on such roofs are held together with adhesives – usually tar that melts under the sun’s heat and seals the seam. When asphalt shingle is used in such roof assembly, the joints between the shingles and the overlaps between them are an easy way for water to penetrate the roof. In the winter, moisture between shingles freezes, expands and breaks the seal. At this point, the roof leaks constantly, and no matter how many patch jobs you do, it will still leak. Also, a low slope on the roof greatly shortens the life of the shingles. Not to mention that when shingles are installed on a pitch of less than 3 in 12″, the warranty is immediately void on them.

While many roofing contractors will try to convince you that with the use of Ice & Water shield such as Grace (considered by many to be one of the best I/W shield products),  will make your roof water-tight and leaks free, the real life experience shows that even on a steeper slope such as 3 or even 4 in 12, the  roof still leaks, and Ice dams find its way inside your house.

A metal roof could be used to solve the constant roof leaks and ice dams on such low slope roofs, but in this particular case (the picture above), the pitch of the roof is too low for even a standing seam metal roof to work, and the best solution in this case would be an IB Flat and Low-slope roofing membrane. Besides, standing seam would cost double of what an IB flat roof cost would be.

Another solution commonly used by residential roofing contractors is the rolled asphalt roofing, or simply rolled roofing. Please bear in mind that most flat roofing systems come in rolls, but each type has it’s own trade name, such as Tar & Gravel, Rubber roofing, etc., and rolled roofing usually refers to a fiberglass membrane saturated in asphalt and asphalt, and coated with stone granules – very similar to asphalt shingles. Learn more about different types of flat roofing materials. Rolled asphalt was a popular choice for DIY roofing projects and many residential roofing contractors would use it, as it was fairly easy to install and easy to buy from a local roofing warehouse, without any special training involved. Unfortunately, these roofs only last about five years, and often begin leaking even sooner, causing expensive to repair structural damages, such as those shown in the picture below. Because the seams of rolled asphalt roofing are sealed with roof cement and fastened with roofing nails right though the membrane, the condensation below and the ice above the rolled asphalt quickly break the seal and the roof begins to leak. Patching such a roof will temporarily stop the leak, but it will actually create more damages as in the meantime you allow water more time to destroy the roof decking and rafters.

We recommend to homeowners with a flat or low-slope roofs to avoid the cheap alternatives which may last you 5 years, and will cost much more the next time you have to replace it, as additional repairs of rotten wood replacement and tear-off / disposal fees add on to the total price tag. Instead, choosing a lifetime IB roof system will make your roof last for decades of leaks free performance and will reduce your cooling costs, as its Cool Roof surface will reflect almost 90% of the solar heat. You will also be eligible to receive up-to $1500 tax credit for installing an Energy Star rated Cool Roof, making your final price almost the same as that of a cheap leaky alternative.

Benefits of installing an IB Roof are many, but here are some of them:

• IB Roofing membrane is a fully watertight system, utilizing hot-air fusion welded seams, which insures a permanent bond between the sheets, flashing and even the drip edge.
• There is no glues or adhesives involved in the installation, as is the case with EPDM rubber roofs. Rubber roofs use splice tape or black glue to keep the seams together, and after just a short period of time the adhesives break down, and the roof begins to leak.
• IB Roof is a complete roofing system with all the components made out of PVC / CPA material, which are welded right to the membrane, ensuring permanent water-tightness. There is a flashing for every possible roof penetration, such as in-roof drains, inside and outside corners, air vents, pipe boots, etc.

• IB Roofing membrane does not cure over time, and remains weldable even 25 years after installation. What does this mean for you? If there is ever a mechanical damage to the roof, such as falling tree branches or accidental cuts, the roof is easily fixed by just welding a patch to the damaged area. No need for special cleaners or glue. Just wipe the dust off and weld.

As an additional benefit to the environment and to your wallet, an IB roof will outlast 2, 3 or even more conventional roofs, which would otherwise have to be dumped in a landfill. As a certified IB Roof Systems Installer, we can install and IB roof for you in any part of Massachusetts, Connecticut & Rhode Island, as well as in southern ME, NH and VT.

We have not updated our roof project profiles in a while, but now since we started using a blog it has become much easier. This is one of the first in a series of projects we’ve completed in the last 12 months, that never made it to our website. We start this series with a flat roof in Connecticut.

I will try to objectively describe the roof problems that our customers had, and what we did to eliminate the roof leaks, as well as give them peace of mind that their IB Cool Roof will protect their home or building, and provide our customers real money savings on the ever-rising energy costs.

Roofing problems and our roof installation in the words of the homeowner:

In December of 2008 my wife and I awoke to a dripping sound in our master bedroom. Much to our dismay the drip quickly became a steady stream of water as we were experiencing a rain storm that totaled 4″. We placed buckets under the stream to mitigate the damages. The next morning I opened up the Sheetrock ceiling which was sagging down. Upon opening the ceiling I could see that all of the insulation and plywood was wet. As I moved across the room I found that it wasn’t just that area that was leaking, but several places. Our flat roof measures 20′ x 34′ and has a 1 pitch covered with 5 year old roll roofing. We tarped the roof and called a water damage restoration company to come in and dry us out. Unfortunately, MOLD was discovered growing on the underside of plywood decking, framing, and Sheetrock. An industrial hygienist was hired to do testing and determine the mold spore levels. We ended up have to demolish the entire area and have the mold professionally re-mediated. The insurance company did not like to hear about mold. Their limit on coverage was $10,000.00 and we were facing $24,000.00 in damages!
This is a very small amount when you see how much it can cost to remove mold. Insurance companies also will not pay to repair your roof. Especially a flat one. They will only cover the resulting interior damage. I was frustrated with the extent of damages that occurred all from what appeared to be a little leak. Often times, by the time water comes through your Sheetrock it is too late and you have lots of mold and wood damage waiting for you. After settling with the insurance company I began to research possible ideas to make sure this never happens again. I investigated the idea of raising the roof pitch, which proved to be very expensive. Next I looked into flat roof systems such as rubber. I found that the seams end up leaking after a while. Not to mention the fact that it is ugly, and retains heat making the inside of your home hotter in the summer. I also looked into metal but no one could install it on such a low pitch and guarantee me that it won’t leak. Finally, I found Leo’s website talking about the IB Roof system. I was amazed by the fact that this product provided a lifetime guarantee for the product and labor. I also loved the fact that it is attractive looking and reflects the hot sun keeping my home cooler in the summer. As an added bonus, in the future I can add IB solar panels to my IB Roof and generate my own electricity. I’m told that in some places the cost for IB Roof may be a bit more than the alternatives. However, for me the cost of the IB Roof was actually less than my quotes to go with a rubber roof. Therefore, it was a no brainier. Leo and his crew were on my job-site within just a few days after our initial contact. It was impressive to see how the construction was preformed and you can really see the quality of the product. Leo and his crew were very respectful of our home and they kept the property clean. I have already recommended Leo and IB Roofing to a few people that I know have up coming flat roof projects. If you are considering a flat roof project you can’t go wrong with Leo and IB Roofing. Do it once, stay green, and enjoy!

Alex from Andover, CT

Roof problems, causes of leaks, and installation of a new IB Roof.

When I first met with Alex, the roof had an expensive, heavy-duty tarp on it and about 5 inches of snow. Although it was the time of a very cold arctic air front in New England, it was actually good for Alex’s roof as cold temperatures kept the snow from melting for a couple of weeks.

“
Flat roof covered with tarp to prevent more leaks

Alex planned to tear-off the existing rolled asphalt roofing with the help of his friends over the weekend and, put the tarp back on, until we would come to install our roof. All went as planned, but it snowed the day after Alex and his friends removed the old roof, and replaced rotten plywood decking and fixed some rafters. On Monday morning snow melted and the roof began to leak again. The heavy-duty tarp turned out to be damaged in few spots, and the roof was virtually unprotected.

We had to adjust our work schedule to quickly come out and make Alex’s roof watertight, to prevent any more water damages and additional repair expenses. Fortunately, the weather was dry for a few days, and on Wednesday we came to install our roof. Once on the roof, we found that there were numerous causes of leaks. The major contributing factor was due to roof rafters caving in, and creating a cavity for water to puddle on the roof.

It is known among roofing professionals that standing water causes the majority of flat roof leaks. Standing / ponding water easily breaks the bond between roof laps, and enters the house, destroying insulation along the way. If left unattended, or unnoticed, these leaks will create thousands of dollars worth of damages, as well as pose a health risk – mold causes and/or aggravates allergies, asthma and other respiratory illnesses.

My evaluation is that most water damages occurred were water ponded on the roof. Other leaks occurred due to Ice Dams, where ice slowly “traveled” between the seams, and melted under the rolled asphalt, causing slow, but steady rot of plywood decking and mold. Although Alex’s roof is not completely flat, Ice dams are known to affect roofs that are completely non-walkable, so this very low pitch roof was an easy “prey”.

Roof Installation:

We use IB PVC roofs exclusively, because in my opinion it is not only the best flat roofing product on the US market, but it creates a completely watertight blanket over the entire roof. With IB, I can look customers straight into their eyes and honestly say: “My roof will not leak!”

New IB flat roof

The reason why IB is such a great roofing system is the hot-air fusion welded seams. Once we weld two sheets of IB roofing membrane, a permanent bond is created, eliminating the possibility of water penetrations. Additionally, IB manufactures all the flashing components, which speeds up the installation process, and minimizes installation error.

Alex’s flat roof is actually an addition and was added as a shed dormer to a pitched roof. When this roof was constructed, builders put in a soffit / ridge ventilation system, which is always a good idea to have for wood roof frame / deck. However, a ridge vent can create many leaks problems, as it is very easy for water to be blown in by wind past the vent, and into the attic.

Normally, roofing contractors would just cover the ridge vent completely to eliminate leaks, but this would take away the ventilation, causing the plywood deck to dry out, de-laminate and slowly “dry-rot”.

We have created a custom design ridge vent assembly for low-slope roofs and shed dormers, where the vent sits two inches above roof level, eliminating the possibility of wind driven water entering the roof. Although the installation of such assembly is tedious and consumes a lot of time, it is the right was to go to maintain proper ventilation and to preserve the roof deck.

Ridge vent assembly for IB flat roof eliminates wind driven water leaks.

As sou can see from the picture, ridge vent sits on top of a 2×4 wood, which is completely wrapped with IB membrane to create a water-tight barrier, and prevent leaks through the ridge opening.

Conclusion:

Overall, it was a straight forward installation which took 2 days to complete.

Special thanks to Alex for providing us with delicious hot chocolate, which made our work easier and warmer during these cold January days.
