Flat roof installation sequence and the way different components are put together can oftentimes be quite confusing. We also get many similar questions about particular aspects of how the roof detail work in different situations. To answer these questions and to demonstrate the step by step process of installing IB PVC flat roofing system, we are posting this quick roof installation guide. We welcome any questions you may have – you can ask them in the comments section at the end of this article.

Installing a flat roof (PVC single ply roofing membrane in this case) can be a pretty straight forward process, or a very confusing endeavor because each component must be installed in a particular order. Otherwise the system may not work the way it should. Of course there is an installation spec manual from IB roofs, which we always keep handy, and actually had to use once or twice. However, this manual only shows particular flashing detail or a general way of how membrane and insulation ought to be installed. It can’t possibly cover all the specifics of the roof installation that come up in the field.

Flat roof installation – mechanically attached assembly:

A reinforce PVC single ply roof allows installers a choice of installing the roof in a fully adhered assembly (sheets of membrane glued to the insulation) or a mechanically attached assembly where each sheet or roll of the roofing material is screwed to the roof deck substrate with heavy duty, corrosion resistant roofing fasteners, and barbed plates. Each roll is screwed to the roof deck on one side, and then the next roll, overlaps a row of screws, and is welded to the first roof, right next to the screws. Then the process continues in the same manner until the whole roof is covered by the membrane.

As you can see in the roof installation picture above, the narrow roll of membrane is installed around the roof perimeter and wider rolls are in place, and are ready to be installed. However, before you get to this point, there is a lot of prep work that has to be done first, and the actual membrane installation is the easy part.

Lets start looking at the prep work, and the order in which things actually happen.

Flat roof installation – prep work – insulation, wood nailer and penetration flashing.

PVC Roofing is a very durable and long lasting flat roofing material. However it should never be in direct contact with any oil and asphalt (also oil) products, and since most other roofing materials are made with oil or asphalt, we always install a protection layer between PVC membrane and either old roof or the roof deck. We usually use insulation to protect the membrane from being in contact with asphalt and also from deck fastener punctures. Roof insulation also serves its primary purpose of improving thermal insulation properties of your roof.

Before we install insulation though, we first install a perimeter wood nailer that serves as a rigid nailing base for the PVC-coated drip edge. Once wood nailer is in place, we lay out the insulation sheets and fasten them to the roof deck, using FM Global 60 or 90 mph wind rating standard – 8 or 10 plates + fasteners per 8×4 feet insulation board (although this is unnecessary, since it is a mechanically attached system). Once the wood nailer and insulation are in place, we install one or more rows of perimeter half sheet, which is a 3 foot wide roll of membrane, vs and standard 6 feet width for field rolls. The perimeter half sheet is installed to prevent wind uplift, and is fastened either 12″ o.c. or 6′ o.c. (for high wind areas).

Flat roofing – tapered insulation:

If there is a ponding water situation, the fastest and most cost-effective way to solve the ponding is to install a so called tapered insulation system, which creates slight roof pitch, which helps divert the water in a required direction and improves roof drainage.

Tapered insulation is basically the same thing as extruded PolyISO insulation with a fiberglass facing. The only difference is that tapered insulation is wider along one edge and narrower along the other. Tapered insulation system can have a roof slope ranging from 1/8″ per one foot run, to 1/2″ rise per one foot run or more. Normally we use a 1/4″ tapered insulation system which raises roof level 1″ for every 4×4′ insulation piece.

Flat roof installation – drip edge detail:

As we mentioned the perimeter half sheet is installed along roof edges, and fastened on the inside with screws and plates – what is holding the half sheet along its outer edge? Well, this is the question that homeowners often ask me. The way IB PVC roof system is designed, allows us to attach the outer edge either directly to the drip edge or run in over the roof edge by a couple of inches, nail it to the fascia board and install a drip edge metal over the membrane.

Both ways are acceptable, but most of the time we use the second method – especially in high winds area. Once the roofing material is installed and flipped down, over the edge of the roof, we install 10 foot sections of 22 ga PVC coated galvanized or stainless steel drip edge, and fasten it to the deck with the roofing screws, either 12″ or 6″ o.c. Then we weld a 5″ wide cover strip of the membrane to the roof and to the drip edge, to seal the screw holes and bake the whole detail water-tight.

Check out our video on how drip-edge metal is installed:

Once the 10-foot sections of drip-edge are installed, the joins are sealed using an aluminum tape and a PVC patch to mack the joint water-tight and protect the patch from metal expansion and contraction. After the joints are complete, the cover tape is welded to drip edge starter and the roof itself, and its now time to do the rest of the roof.

As a side note, there are many options for drip edge detail. Although the most used drip edge is the 2 or 3″ wide face, white starter, you can also choose it to be as much as 8 or more inches wide, as well as in gravel stop style (if you need to divert the water flow or prevent it from going over the edge of the roof.

Gravel stop drip edge has a 1″ bump-out, which stops water from spilling over, and makes it run down the roof – toward a drain or a gutter. Drip edge comes in two colors – white and dark bronze, and also can be painted any other color with acrylic paint. IB roofs also offers 16 oz. copper drip edge, with PVC material adhered to the flange, and can produce any style drip edge, with different angles, kick-in or kick-out face and in various widths.

Flat roof installation – field sheets, roof penetrations and roof to wall termination:

After all edge detail is complete, we install the field rolls of membrane and all penetration flashings, such as pipes, drains, HVAC / Skylight curbs, roof hatches, chimneys, etc.

IB Roof Systems produces a wide variety of flashing accessories, which allow installers to quickly and easily flash almost any roof penetration. Since all roof components are made of PVC, they are all welded together, and the use of any adhesives or glues is completely eliminated, as well as most installation errors by roof mechanics.

All curb and up-the wall flashing is installed using a two-step process. First, the roof is terminated that the wall, and then a separate piece of membrane is installed up the wall and welded to the roof.

After the flashing is installed and welded to the roof, the inside or outside corner flashing is welded to make a permanent watertight joint.

All IB flashing accessories are made of 60-mil non-reinforced flashing membrane and can stretch to perfectly adhere to any shape of a penetration on the roof. Pipe flashings and drains have a reinforced flange to be welded to the roof.

Bellow is a video demonstrating the curb flashing installation around a skylight:

As you can see in the video, the roof penetration flashing is a very clean process, and a chance of a leak is minimum to non. Unlike flashing details on a rubber roof, where a membrane cannot and should not be terminated at the base of the curb, due to high possibility of a leak caused by adhesive failure, the hot air welding process used in sealing overlaps and seams on a PVC roof, eliminates leaks, as well as membrane pull-out caused by contraction of the roofing material in cold weather.

Flat roof installation – special flashing details:

IB roof spec manual does not cover all installation details, as in the real world you often run into situations where you have to “improvise”, while your roof must still be watertight. One such example is the ridge vent detail on flat / low slope roofs such as shed dormers. While many low slope roofs are considered “flat”, they were built as sloped roofs with ridge / soffit ventilation in mind. However, many roofing contractors that install EPDM rubber roofs, block the ridge vent opening completely to prevent roof leaks.

We’ve developed a special assembly method, which allows us to still use the ridge vent, and keep the roof watertight. We run our roof up-to the ridge opening, weld additional strip of membrane, install a 2×4 wood to raise the level off the roof, flip the strip of membrane back and wrap the 2×4 with it. This prevents wind driven water from penetrating the roof, and ridge vent + ridge cap is installed on top, 2 inches up.

As you can see, IB PVC roof can be adjusted to virtually any type of flat roof, and roof penetrations. We recommend that you check out more roof installation videos on our Roofing Videos channel on YouTube.

You can see more examples of flat roof installations that we have done all over New England: Roofing in Massachusetts and roofs in Connecticut. We provide residential roofing and commercial roof installation services in all New England states. However most of our work takes place in MA, CT and RI.

Also, if you have a flat roof deck that is leaking, check out our roof deck section, to learn more about IB roof installation on flat roof decks, patios and balconies, using special slip-proof roofing material called IB DeckShield.

Roof decks leak problems and solutions:

Many homes have an outside deck / patio over a living space, and so far, the solution to waterproof such roof decks was to install a rubber membrane roof and a wooden deck on slippers over the rubber. On some older roofs, instead of a rubber roof, a Tar / Built-up roofing material is used for waterproofing. The main problem with this assembly is roof leaks, which often occur within a few years of the roof deck’s installation.

Often the seams on the roofing membrane pop open, or water starts to pool under the deck, and the only way for this water to drain is into your home. If you need to repair such a roof deck, you will have to take the deck apart completely to seal the seams or to redo the roof flashing, and then put the wooden deck back together.

Another issue is the cost of such a roof deck (even without the high costs associated with roof repairs) – the rubber roof by itself is somewhat not expensive, but when you add the cost of a pressure treated wood deck (a fiber decking, mahogany or some other premium deck is rather rare, and most people do choose to go with PT wood), your roof deck ends up costing you a small fortune. Then you also have to install and seal the railing posts.

On a rubber roof, pieces of uncured flashing must be glued to the rubber roof and the post to make the post penetration watertight, and on a Tar / BUR roof, liquid tar or roof cement is used to seal around the post. Both rubber roof flashing and tar flashing around the post will begin to fail after 5-7 years, so once again to stop the roof leaks, you will have to disassemble the deck and repair the flashing.

IB Deck Shield – the long lasting, beautiful and cost effective solution for roof decks

IB Roof Systems recognized the need for a long-lasting waterproofing membrane for roof decks, patios and balconies, and based on their excellent PVC roofing membrane, created a Deck Roofing product, which will last for decades, is easy to repair (if such need arises), and has a special, slip-resistant, beautiful surface. This makes it possible to walk on this membrane, eliminating the need for a wooden deck over the membrane, and making the whole roof seamless and watertight.

IB Deck Shield was created based on IB Roofs’ proven PVC roofing membrane, designed for flat roofs, and featuring hot air welded seams, which make membrane overlaps sealed permanently, ensuring a long-lasting watertight roof. An IB roofing membrane can withstand ponding water, and is an excellent choice for any flat roof. IB roofs also have a complete line of flashing accessories – inside and outside corner flashings, pipe flashing ranging in size from 1/4″ to over 12 inches, for extra wide exhaust pipes and furnace stacks. Because of fast and easy installation in all tight spots, any roof penetration can be flashed quickly and any installation defects are eliminated.

IB took it’s existing it’s existing PVC roof product (IB Flat Roof), and added a special surface to it, making it slip resistant, even when wet, and added a beautiful texture, which resembles small pebbles, often used as a swimming pool deck. All components of IB Deck Shield roof are color matching and will produce a uniform, great-looking final product.

IB Deck Shield roof installation:

Because an IB Deck Shield is exposed to constant foot traffic, deck furniture, outside BBQ grills, etc., it must withstand all this abuse and last for many years without any leaks. To be able to do so, an IB deck Shield is installed over a dense, moisture resistant substrate – DensDeck, which is attached to the roof deck.

Once DensDeck substrate is installed, all seams are taped and “plastered” with a special joint compound to provide a universal, smooth surface, to which the Deck Shield membrane is glued using either a water-based or solvent based adhesive (we use water based glue, as it is environmentally “safer” than a solvent based product).

When a a joint compound cures, we apply a layer of IB water-based adhesive and lay down the IB Deck Shield membrane, which was previously aligned to be wrinkle free and to have exactly a 2″ overlap with the previous sheet of membrane. Once adhesive is applied and membrane is laid down, it is mechanically fastened at all roof to wall connections, but never in field.

After a few minutes, when adhesive cures, all seams are welded and it’s time to install roof to wall flashing as well as all pre-fabbed inside / outside corners, as well as flash all post penetrations. IB Roof manufactures special post flashings, which can either be pre-welded or split, and it is the choice of a contractor which one to use.

We prefer to use split post flashings – although the split post flashing requires more welding, it is actually easier to install split flashing rather then a welded flashing, because when we order them, we specify the post size – usually 3 5/8″ x 3 5/8″ (a standard 4×4′ railing post), and a welded flashing sits pretty tight around the post so it is rather difficult to pull it all the way down.

Durability of IB DeckShield flat roof decks:

Once all DensDeck is installed, all DeckShield is glued down, seams welded and all flashings are installed, the roof is complete, and now you have a durable, completely water-tight roof deck, where you can spend nice summer days, invite your friends over for BBQ, and not worry about roof leaks any more. IB DeckShield is VERY durable, and very resistant to puncture damage. Because it is glued to the DensDeck substrate, the surface under it is very hard and most sharp objects that fall on this roof will bounce off leaving very little or no damage – we accidentally dropped sharp tin snips; they just bounced off and did not cause any damage.

Of course you want to be careful with your new roof and not drop any sharp objects purposely, but small accidents do happen, and you can be confident that IB DeckShield will withstand all normal wear and tear – foot traffic and most accidental drops, which would usually puncture a flat roof such as rubber roofs.

If your roof is damaged – in most cases it should be leaking for a long time, as the membrane is glued to the substrate and even if some water gets in, it won’t be able to spread and leak inside your home. It is also very easy to repair an IB Deck Shield roof – a small patch of color-matching membrane will be welded over the damaged area, making the repair virtually invisible, unless looked at from close distance. An IB DeckShield roof will remain weldable for decades, just like other IB Flat roofing products.

Roof deck prices – how much does IB DeckShield cost to install?

IB DeckShield is a premium flat roofing product and it is rather expensive by itself. However, when you consider the alternative of a rubber roof with a PT wooden deck over it, IB DeckShield will usually be less expensive, as PT wood deck will add a significant amount to the total roof deck cost.

Because IB DeckShield installation is rather complicated and involved, it will cost more than the flat roof prices provided by our roofing calculator. IB Deck Shield takes considerably longer to install than regular IB flat roofs, and costs a lot more than a standard 50-mil or even 80-mil IB roofing membrane. Therefore installation prices per sq. ft. of your roof deck will be higher than those of an 80 mil roof deck option (eg. flat roof deck in Wellesley, MA)

Price of IB Deck Shield installation will also depend or roof difficulty, number of roof penetrations and whether the existing roof needs to be removed. In case of a roof removal, the roof deck must be installed in sections, and sealed at the end of each work day, to prevent roof leaks from overnight rains.

IB Roof Deck prices:

A basic price to install IB DeckShield starts at $13-14 per sq. ft. (assuming that your roof deck is approximately 200-300 sq. ft., which is what most roof decks are), and includes a 1/4″ DensDeck Substrate, with all joints sealed using joint compound, and up to 5 post flashing penetrations. All other flashing and penetration details will be priced considering other aspects of your roof, and the project as a whole.

Roof tear-off will be priced in a range of $300+ per 100 sq. ft. of roof area, plus cost of the dumpster. The reason for this price structure is as follows: Roof decks are usually rather small, but the tear off greatly intensifies the installation difficulty and slows down the overall process. Also, we separate dumpster fees, as on a small roof we would still need the smallest (10 or 15 yards) dumpster which costs about $300.

To give you an example – it took us about 5 days to complete the roof in the first picture on this page, with 4-5 guys working 8-10 hours per day. The roof size there is approximately 1200 sq. ft. So assume that 4-5 guys removed and installed about 240 sq. ft. of roof in 1 day.

The pricing above is approximate and reflects a general price stricture that we use for deck roofs installation in Massachusetts and the rest of New England states (Roofs in CT, RI, NH, ME and VT).

We will price each roof deck separately, but this will provide you with pretty accurate pricing guide-lines, so you would know how much to expect to pay for an IB DeckShield roof.

As a comparison, a rubber roof would cost you $8-10 per sq. ft. plus the cost of PT wooden deck, which can range from $13-20 per sq. ft., often without the material costs.

As of June 23, 2008, we now offer our customers a choice of using Recycled on New Poly-Iso insulation.

Benefits of using recycled insulation include instant and continuous financial benefits. Since we get recycled ISO board at a discount we pass on the savings to you, and with more insulation for the same amount of money you would spend on a new ISO, you will continue to save money on your energy costs year round.

But that’s not all! Although ISO insulation is not “green” per-se, using recycled insulation is a green choice since by reducing your energy consumption, it will also reduce carbon monoxide emitted into the atmosphere. It will also not go into our nation’s land-fills, therefore it will benefit the environment.

Types of insulation we use:

By default we use a 1/2 inch fan-fold Styrofoam insulation, which is mostly used when there is already some insulation on the roof. Fan-fold insulation comes with 2-R value, so it will add some insulating value to the roof. It also acts as a separation barrier between the deck or old roofing material and IB membrane. Fanfold insulation is attached with heavy-duty screws and corrosion-resistant insulation plates. It is light-weight, features quick installation and is ideal for a roof layover. It is also the most economical option.

As an option you may choose to use a common ‘new-construction’ and complete roof replacement choice of insulation – Poly ISO board, which comes in a wide range of sizes and features high R-values from 3 to 20-R. Sizes include 1/2, 1, 1.5, 2, 2.5, 3 and 3.3 inches and R-value is calculated using 6-R per 1 inch of insulation.

If drainage is a concern, ISO insulation comes in tapered design which has different thicknesses at each end, and is used to create pitch ( slope ) on a completely flat roof. Slope is usually directed toward drains or drip edges and diverts the water flow to where it can exit the roof.

We are an Eco-Friendly, full service flat roofing company specializing in installation of Cool Roofing systems for a wide range of Residential and Commercial roofing projects. We carry all necessary General Liability and Worker’s Compensation Insurances, OSHA certifications, and are a Licensed IB Roof installer.

Our installers and roof mechanics work safely, wear all necessary safety equipment and use state of the art installation tools and equipment. We pay top wages, and provide premium workmanship and services.

While a standard labor warranty in the roofing industry (a minimum required by law) is the 2-year period, all our roof installations include a Labor warranty that matches the material warranty (i.e., 80-mil IB membrane has a 25 year material warranty, which we match with our 25-year labor warranty).

Roof consulting service:

We offer roofing consultation services which include complete analysis of your present roof condition, inspection of structural components, roof deck and roof insulation. We analyze your roof’s drainage situation, and identify whether you may need more insulation, drains / scupper, or other roof components installed to improve your roof’s performance and extend its service life. We will provide you with a complete report of what has to be done on your roof, and identify parts you may not need. We can also negotiate with your General Contractor and/or Architect on your behalf, to get you the right products/services, while including needed items, and eliminating unnecessary and costly items. This will prevent future “change orders” and up-charges from your GC / Architect / Contractor, and save you money and frustration.

Does your Commercial / Industrial / Restaurant roof leak?

• Do you have to install plastic covers or tarps to protect your expensive machinery?
• Does water damage your office computers and equipment?
• Is your product inventory being destroyed by roof leaks?
• Do you loose business space, restaurant seating, and production capacity due to your old, leaking flat roof?
• Does your black rubber or Tar & Gravel roof make the AC run continously, while it is still hot inside?

All of the above is true for these folks, and they are sick of it!

As you can see, they had to protect their VERY expensive machinery with plastic sheets just so water does not destroy it. Flat roof leaks can cause thousands of dollars in damages to equipment and merchandise alone. Consider redundant roof repairs and costs associated with future replacement rotted decking, wet insulation, and disposal of old roofing material. Add lost business productivity, equipment repair, replacement and damaged inventory. It is time to eliminate your flat roofing leaks once and for all.

The choice is simple – IB Single-ply Cool Roof

A leaky roof creates major problems for many businesses, in lost revenue, damaged equipment, and lost business space. We can help you stop those leaks once and for all with IB PVC Roof – our flat-roofing product of choice – and we will back it up with our comprehensive guaranty that you will not have any more leaks.

With Commercial warranties up to 25 years and a proven track-record of over 30 years leak-free performance, an IB roof will be saving you money on maintenance, repairs and energy costs. IB Cool roofs reflect over 90% of solar radiation and on a 90 degree day White IB roof will only go about 95 degrees. Compare that to 160-170 degrees for a black rubber ( Epdm ) roof.

IB ChemGuard – the only chemicals, oil and grease resistant roofing membrane available on the market will be the perfect choice for any restaurant or industrial manufacturing facility where chemicals may be present on the roof.

Most businesses require a lot of space to operate efficiently, and it just so happens that most commercial buildings have a flat roof. These flat roofs just leak, and there seems no end to these roof leak problems. Leaking flat roofs not only cause expensive repairs and structural damages, to the building – they can potentially halt some or all of your business’ production until leaks are fixed. Temporary loss of useful space can be more costly than the roof repair, and the damages to your production equipment may by far outweigh the cost to install a Long Lasting IB Flat Roof, which will not only remain water-tight beyond it’s warranty period, but will also save you money on the ever-rising Cooling and Heating bills. IB’s excellent ‘Cool Roof’ reflective properties can lower your AC energy consumption by as much as 20%, and with the addition of High-R insulation, it will be less expensive to heat your building.

Even ponding water is not a problem for IB Roofs.

IB Roof was created with the commercial / industrial flat roofing market in mind, and will work on the most complicated flat roof you can think of. If your flat roof has inherited water drainage problems, has devastating ponding water after every time it rains, it is no problem for IB. it comes with an explicit ‘Ponding Water Warranty’, unlike most other flat roofing systems, which will leak and whose warranty will be void if there is standing water.

IB Roofs are Eco-friendly – IB is the Green Choice!

Not only are IB roofs perfect for commercial buildings in terms of water-tightness, longevity and performance, they are also friendly for the environment. Cool roof features an IB white membrane that will reduce the CO2 and other Green-House gas emissions by reducing your energy consumption for Air Conditioning. An IB roof is also a perfect choice for creating a Green Roof or a Roof-top garden which in an Urban Environment will reduce the “heat island” effect and will increase the productivity of your office workers, as proven by multiple studies.

Another great feature of IB roofs it that they are 100% recyclable. This means 30 years from now, if you decide to get a new IB roof, the existing one will not go to our nation’s landfills. Instead, it will be recycled and reused for other PVC products such as vinyl siding, PVC pipes and conduits, etc.

When you want the looks of an Architectural Shingles and unsurpassed reliability of an IB Roof, IB Traditions gives you both!

IB Cool Flat Roof – The Best flat roofing for your Home!

An IB roof has its roots in commercial flat roofing, where the requirements and expectations of building products are much higher than in the residential market. In fact IB Roof has been chosen as the roofing choice for Hospitals, Airports and Universities through-out the country, where a leaking roof is not an option. Many of these roofs installed over 25 years ago are still performing well, without any leaks.

Ice Dam leaks and poor ventilation:

Most low sloped roofs in the northern United States have Ice Dams, which cause roof leaks and expensive roof repairs as well as cosmetic interior repairs of ceilings, walls, carpets and wooden floors. Those are the damages that you can actually see. Ice dams also create invisible structural damages which you can’t find until you open up ceilings and walls. These damages are extremely expensive to repair, as it would require to hire interior remodelers to fix structural damages, outside and inside walls, electrical systems, plumbing, etc.

Ice Dams in a nutshell: Ice dams are caused by poor attic ventilation and heat loss from the inside of your living space. Large piles of snow will accumulate on your roof after a snow storm. If your attic is improperly insulated and ventilated, the warm air escaping from your living area into the attic, will melt the snow. The water from melting snow will run down the roof and refreeze, usually along the eaves of your roof. These are Ice Dams. The more snow is melting the bigger Ice Dams you have. After some time, the ice dams become so big, that the melting water cannot travel downward anymore, so it starts to travel upward underneath the roof shingles or rolled roofing seams. As it freezes under the roof, warm air melts it, and it slowly starts to drip inside the attic, causing all of the above and below mentioned problems.

It becomes a vicious cycle were more heat loss creates more ice dams, which causes more damages to structural walls and insulation, destroying your home from the inside, increasing your energy-related expenses, and causing more heat loss, which creates bigger ice dams…

One negative effect caused by Ice dams, and which many homeowners neglect to address is the wet insulation in the attic and inside walls. When insulation gets wet, you loose insulating value, so your energy costs increase, as heat loss in the winter drives up your heating bill. The same happens in the summer with cooling. Also, mold begins to grow in the attic and inside walls, which cause and/or aggravates allergies, asthma and other respiratory illnesses.

Solution to Ice Dams problems on low-slope roofs:

IB roofing membrane is perfect way to eliminate Ice Dams on a low slope roof, as it is a seamless blanket over the entire roof. Hot air welded seams prevent water from backing up and re-freezing as is the case with shingles and rolled asphalt roofing, therefore eliminating the effects of Ice Dams. Also, Most of the snow will actually slide off the IB roof, thus there will be a minimal Ice and Snow accumulation along the eaves.

Additionally, we’ve designed a special Ridge Vent system, which we use on every low-sloped roof with ridge/soffit ventilation in place. This system prevents the wind driven water form entering your attic space through the holes in the ridge vent, while allowing the warm air to escape the attic.

Now you too can have this outstanding roof installed on your home. IB make the perfect choice for any residential flat and low-slope roof. IB roof will give you years of worry-free service, and make your home more energy efficient, as well as provide a transferable Lifetime Warranty! IB will also add beauty and usability to your home with its specialty Traditions & DeckShield membranes.

Roof deck & leaking.

Many homes in New England have a walk-on flat roof decks with living space under them, and 90 percent of these deck roofs leak, ruining your rooms. Stains on sheet-rock ceilings, popping hardwood flooring, wet carpets and rotted framing are just some of the damages that you may sustain as a result of these leaks. Destruction of personal property such as beds, book shelves, computers, TVs and other electronic equipment can also occur in cases of severe roof leaks.

All these items are very expensive to fix and even more expensive to replace. Yet you can easily solve these problems in a fairly cheap way (when compared to costs of replacing and repairs you have to incur if you let the leaks continue) with IB’s life-time roofing product. With IB Roof, you will never have to worry about roof leaks again and you could finally regain full use of your roof deck or patio.

Creating a leak-free Roof Deck with IB roofing systems

We offer two different solutions for you to permanently solve your roof deck leaks. Both ways utilize IB’s time-proven CPA membranes featuring hot-air welded seam. The main difference between the two methods is the product you choose to use, and aesthetics you desire.

Cost of flat roof decks

Why roof decks leak?

Most roof decks in existence today use a flat roofing material that were created over a century ago and were not designed for use as roofing for residential homes and living area. Another reason is original design flaw implemented by architects and/or builders, who were not qualified in flat roofing and did not have appropriate roofing technology to use.

Ponding Water leaks:

Very often you can find ponding water accumulating on these deck roofs. Majority of flat roofing system existing today cannot sustain constant ponding water and as a result water enters your house, and destroys your possessions and property.

Wood Deck and Railing leaks:

Often there is a wood deck installed on top of a flat roof or some sort of a railing system. To make these railings securely attached to the roof, builders often create roof penetration for every railing post on the roof. The only way to “seal” these penetrations for most builders, is to use roof cement or pitch-pockets – both of these methods are considered unacceptable by the National Roofing Contractors Association (NRCA). Yet most builders don’t have the appropriate products, expertise and many times, don’t care enough to make these penetrations water-tight.

This results in more leaks – usually these leaks don’t appear inside your home for years, but the hidden damages can cost thousands of dollars to fix. Water slowly enters your home and rots the beams and studs. While unnoticed for a long period of time, such leaks my sometimes result in partial or complete re-framing of your roof and/or support walls.

Leaking Flat Roof Deck

Details of roof deck construction using IB Membranes and DeckShield

IB DeckShield roof / deck assembly and installation:

DeckShield is easiest to use in new construction, however it can be easily adopted for retrofit use on existing homes. IB Deck Shield is installed as a fully-adhered application on top of Dens Deck – a fiber-cement type board that is 1/4 of an inch thick, or over plywood.

The surface for installing IB DeckShield must be clean, smooth and flat. That is why in some retrofit applications use of DeckShield may be difficult or impossible. When you have an uneven surface it is best to use the regular IB Roofing Membrane with a wooden deck over it. If you still want to use Deck Shield for a retrofit roof deck project, expect the additional costs of making your roof surface even.

DeckShield can be used for a small balcony as well as a large roof deck, and for everything in between. Hot-air welded seams make IB DeckShield a long-lasting waterproofing solution that is both eye-pleasing and safe to walk on when it is wet. Expect many compliments from your family and friends when they get to see your new roof patio with IB DeckShield.

DeckShield colors and texture:

DeckShield has a look and texture of tiny pebbles – something similar to a floor in a swimming pool. You can choose between two distinct colors – Tan and Grey – both look great and will compliment your home.

Since IB DeckShield is made from the same material as other IB membranes, it is easy to accommodate for any roof penetrations, such as a Railing System and Roof-Wall detail. This will ensure that your roof will be water-tight and you can take full advantage of your deck or patio once again, and will not have to worry about leaks. Invite your friends and family for a cookout, enjoy a cocktail, or watch the stars.

IB SolarWise roof-integrated Photo-Voltaic systems:

IB SolarWise Roofing is a Revolutionary Product combining Permanent Flat Roofing and Renewable Energy in one easy-to install, leaks-proof flat roofing solution for environment and money conscious Home and Business owners, and has a pay-off period of under 5 years*, while industry standard is 7-10 years or more.

IB SolarWise utilizes Thin Film laminate Solar PV modules produced by Uni-Solar – a US manufacturer of Solar products. Both IB Roofs and Uni-Solar have been in business for over 30 years, and combining their respective experience in Flat Roofing and Solar Photo-Voltaic gives you the highest quality, Super-Energy-Efficient product for Residential, Commercial or Industrial buildings.

SolarWise is more than just a system – it is a way to integrate two different system to work seamlessly, to be leaks free and maintain its warranty without incurring additional costs for the building owner.

IB Solar Wise helps roofing contractors and solar integrators eliminate their biggest worries – roof leaks and solar photovoltaic equipment damages by creating a seamless integration between two previously incompatible technologies.

IB SolarWise Video

Until recent availability of IB SolarWise system, solar integrators had to rely on caulking and screws to attach solar panels to the roof surface. This created leak problems for which solar integrators did not want to take responsibility. Roofing contractors were ‘terrified’ of solar equipment and its sky-high replacement cost in case of damage during roof repair. Now all these problems are eliminated by integrating solar PV components into a long-lasting IB roofing membrane, resulting in the elimination of leaks, reduced solar and roofing installation & materials costs and reduced requirement for dead-weight load on the structural components of the building.

IB SolarWise Prices

Here we will demonstrate a cost structure for a hypothetical 3 KW solar PV system installed on a roof of home or business. Do understand that this cost includes the installation of IB Roof, BIPV Solar panels, Inverter, wiring, etc., and the prices are provided “before” any Federal tax credits and State rebates for solar and other renewable energy projects.

Lets assume that our roof is an average residential roof that is 1500 sq. ft., which has a slight pitch and is positioned in a southern direction with no shading (perfect conditions for solar PV installation). Please note that slope of the roof, shading or southern exposure do not directly affect your cost for a solar system, but these conditions will affect your system’s efficiency and total electricity output. Theoretically, on a 1500 sq. ft. roof, we can install up to 7 KW of IB Solar Panels, but for the purposes of this example we will use 3 KW system mentioned before.

There is a lot of confusion about how the solar PV systems are priced – many people assume that solar is priced by Square Foot, but that is the furthest thing from the truth. Because Solar Panels from various manufacturers have different efficiency, the electricity produced by 15 sq. ft. panel from Manufacturer A can be double that produced by same size panel made by Manufacturer B. Therefore all solar PV systems are priced by their output measured by Watts DC. The average industry cost for solar PV systems that are rack-mounted and installed on an asphalt shingles roof of a residential homes range from $10 to $12 per Watt DC.

IB SolarWise PV system utilizes a thin-film Solar PV laminates produced by Uni-Solar Ovonics. These solar panels have lesser efficiency than a more common crystalline silicon panels (big aluminum boxes) per sq. ft., therefore they require more space to have a large size solar array installed. However that is rarely a concern as usually there is plenty of unused, unshaded space on the roof. Prices of IB Solar Wise PV are in the range of $13-14 per Watt DC. This is slightly more than your conventional PV panels, but it also includes a Lifetime roof, and provides a complete, water tight system, which is guaranteed not to leak, as is often the case with conventional PV systems installed on rack mounting systems, which are bolted to the roof.

The $13-14 per Watt DC figure is flexible and a lot depends on the size of the roof and the size of the solar system (number of KWatts), and in some cases can actually be on par with cost of conventional Solar systems, which do not include the roof. Each individual project will be different, so use these numbers for reference only.

Also we recommend that you read the next section of this article, discussing why you would want to have a a roof-integrated solar system installed vs. a conventional solar system.

Solar Flat Roofing: Cautionary tale with the end in mind

Foreword: This story is fictional in nature but real in substance, and definitely happened before.

A brave, responsible, and hard-working person – Jack – decides that installing a Solar PV system is not only beneficial for the environment, but is also a sound investment. So after doing the due-diligence he lines up a solar integrator to install the Solar System on his 7 years-old flat roof. The roof has no signs of leaks and Jack feels that there won’t be any problems.

The solar integrator knows his job well and completes the project in a timely manner, applying for and receiving all the available incentives for the client. the system performs well as expected, and generates the expected amount of electricity. All goes well.

3-5 years later the roof begins to leak and the building owner is faced with a dilemma. He needs to stop the leaks but the solar equipment is in the way. The roofing contractor who is supposed to fix the leak hesitates to move the solar equipment, which prevents him form fixing the roof. The only option is to remove the solar panels array completely, remove the old roof, install a new roof, and then put the solar array back.

Excluding the cost of re-roofing, as it is not related to the solar system, the hero of our story had to pay at least a dollar/watt for removal and a dollar/watt to put back the solar panels. Lets say he had a small commercial system of 10 kW or 10,000 watts. This means that he had to pay EXTRA $20,000 just to take the solar system off and put it back on, so the roofing crew could do the work.

Why was this a cautionary story with the END in mind? Very simple: Jack could avoid the extra expense of $20,000 by using a roof-integrated solar system such as IB SolarWise. Cases like this one happen all to often, and not just with flat roofs. A more common example would be an asphalt shingle roof with a solar pv system, where shingles not covered by solar panels deteriorate at normal rate and will have to be replaced about every 15 years. Lets face it: Shingles rarely last more than 15 years. Consider all the roof penetrations form the solar panels’ rack mounts and the roof lasts 12 years, after which the process described above has to accrue, unless of course you are willing to take the roof leaks.

IB SolarWise roof saves you money in FOUR ways:

1 – IB Cool White PVC roofing membrane reflects up to 90% Sun’s heat, thus your AC does not have to work as hard as if you had a black roof. Read more about benefits of IB Cool Flat Roofs.

2 – SolarWise PV modules (solar panels) generate free electricity** by converting sun-light into Electricity you can actually use, so you do not have to buy it from your utility company, or you buy a lot less than you had to before. In some cases your IB SolarWise PV system will produce MORE electricity than you expected, and you electric company will buy it from you at retail price, in states that have Net Metering laws (most states).

You will also be able to sell so called Renewable Energy Credits or RECs to give you even more money for extra electricity that you produce, thus speeding-up you pay-off period! But that is not all – there are also numerous incentives, grants and tax-rebates offered by Federal, State and local Governments, as well as your utility companies.

3 – IB Roof’s durability and proven performance ensures years of leaks-free operation of you roof as well as virtually no maintenance. As a result, you save money on flat roof and interior repair, which you will otherwise incur with other flat roofing systems, renowned for constant roof leaks.

4 – IB SolarWise PV system will save you money on the installation costs. SolarWise PV is a Building-Integrated PV (BI-PV), which means it is actually a part of the IB flat roofing system. This eliminates the need to use expensive solar panel mounts, brackets and railings that take long to install, therefore adding a lot of money to the total cost of the installation.

How IB SolarWise PV works?

IB SolarWise PV produces DC-current, which goes into an Inverter where it becomes AC-current. The inverter is connected to you home’s or building’s electric circuit and also to your meter. You use all electricity you need, while ALL excess electricity goes into the Grid. Electricity that goes into the grid is purchased from you by your utility company through Net Metering, usually at retail price.

Most of the electricity produced by the SolarWise PV system occurs in the summer, when days are longer and more sun-light is available. At the same time people will usually use a lot more electricity in the summer to run the Air Conditioning units, so depending on the “size” of your solar system, you will produce more, less or the same amount of electricity than you actually consume. However, practice shows that in the summer months, Solar systems produce more electricity then is consumed. Therefore, all excess kWh sent to the grid in the summer you will use in the winter, when a lot less of sun-light is available.

• Q: Can I install IB Solar Wise panels over EPDM Rubber (Modified Bitumen, Tar roof, etc)
• A: No. IB SolarWise PV system must be installed over IB roof. The solar panels are welded down to the IB PVC roofing membrane which acts as a water-tight barrier and a substrate for IB Solar
• Q: How much does a square foot of IB Solar PV cost?
• A: IB SolarWise PV system as well as other solar systems are not priced by the square foot, but rather by $/Watt DC. Please refer to our IB Solar PV pricing section for more details
• Q: What is the output of IB SolarWise PV module
• A: IB SolarWise PV modules come use 4 Uni-Solar thin-film laminates per module. Each Unisolar module is 136 Watts DC, so each IB SolarWise PV module is 544 Watts. You also have an option of getting modules that are 1/2 the physical and output size and are 272 watts.
• Q: How many KW of IB solar can I install on my roof?
• A: The 544 Watt IB SolarWise PV modules is 19 feet long by 6 feet wide and require 120 sq. feet of unshaded roof area. Therefore, for 1 Kilowatt of electrical output, you will need about 200 sq. feet of roof. However, since IB Solar modules come in sizes of 544 Watts, you need to calculate how many modules you want installed and how much unshaded roof area you have.

When it comes to replacing your flat roof, you need to think long-term. Getting a cheaper roof, such as EPDM Rubber, may be appealing at first, but you need to consider some factors that will affect the total price of your new roof. Here we will discuss in detail what the total roof replacement price includes, and factors affecting it.

Installation price from every roofing company also includes that company’s overhead or cost of running the business. For example, an established roofing company should be fully insured. This includes adequate Liability and Worker’s Comp Insurance. If for example you get a very low bid, consider that the bidder might not be adequately insured or have no insurance at all. If that is the case and you hire such a contractor, you will be responsible for any damages or injury claims that may occur.

Introducing IB PVC Roof – the longest lasting flat roofing system.

Over the last 30 years, IB Roofs, once a small family-owned company importer and installer of German-developed PVC flat roofing systems, has become a household name in the flat roofing industry. There is a reason for IB’s success – it is the ultimate quality of their products and unparalleled customer service. IB’s original roofs from 30 years ago are still in service and performing well, and when it comes to working with customers, IB will go out of their way yo give you the product you are looking for – be it a color of the membrane, a thickness, or special application requirements.

Quality of IB Flat Roofs:

IB Roofs has not changed the formulation of their PVC membrane since its early days in the late 1970′. Today’s IB membrane is the same great proven product that they were importing from Germany 30+ years ago. IB did not try to make the product cheaper by using less expensive components and fillers. On the contrary, IB has chosen to use the more expensive non-wicking scrim to prevent the membrane from splitting in the center due to water penetration, as is often the case with cheaper TPO roofs.

At some point, there comes a time when flat roof patches stop working and it is time for a replacement.

Here we will review flat roofing cost structure and factors affecting your price, IB Roof prices in Massachusetts and surrounding states ( CT, RI, NH, ME and VT). We’ll also reveal insights into choosing your flat roofing contractor, and what you should expect to pay for your particular roof, as well as your specific roofing product choice.

Flat Roof Replacement Cost: Residential and Commercial

Our general pricing for flat roof replacement works in the following manner:

Residential flat roofs are priced at $675 per square for a simple roof, with no existing roof removal. This includes 50-mil IB Roof membrane, 1/2 inch foam insulation with 2 r-value, perimeter pressure-treated wood nailer and half-roll membrane around the roof edges for wind-uplift prevention. Roof attachment using heavy-duty screws and barbed plates, 6 inches O.C. along the perimeter and 12 inches O.C. in-field. All required roofing parts and accessories are included.

Generally, for a 1000 sq. ft. residential home, your cost should be around $6750 for an average (simple) roof. If you would like to upgrade the membrane type or add more insulation, this will slightly increase your price. Please note: For all residential installations, all IB roofing membranes come with a lifetime residential warranty, therefore there is no need to upgrade from 50 to 80-mil product, as both will perform the same in protecting your roof from the elements and will remain water-tight throughout its life and beyond.





Commercial flat roofs are priced at $600 per square for roofs over 25 squares (2500 sq. ft.) The price difference from residential roofs is due to ‘economy-of-scale’ factors and lower per-square ‘setup’ and insurance costs.

If your commercial roof is around 50 squares you can expect a $30000 price range.

Use our interactive roof price calculator to estimate the cost of you roofing project. You can choose different roof options difficulty level, and will get ‘quotes’ for an IB roof, as well as other roofing products and approximate energy-savings derived from using an IB roof.

Please Note: All prices described above are assuming an ‘average’ roofing project and may/will change depending on your roof’s condition and scope of work required. The price may change in either direction, and will be determined on a case-by-case basis.

We are a premium roofing contractor and do not compete with other roofing companies solely on price. Our roof packages are priced accordingly to the quality, warranty and customer service we provide.

For custom colors the minimum order must be 100 squares ( This is the requirement of IB Roof Systems, and we have no control over it).

One: Roof Installation Prices

Our pricing structure is based on two direct (main) variables and a number of indirect variables that affect the total price of your roof replacement project. You can expect similar pricing methods from other roofing contractors.

First cost variable: Roof Size

The most important variable is the size of your roof. The bigger the roof, the higher the roofing cost. We base our pricing on the number of Squares, where each square is equal to 100 sq. ft. For example, if your flat roof is 1900 sq. ft. it is 19 squares.

Second cost variable: Roof difficulty

The difficulty of roof installation is the second most important variable affecting the cost of your roofing project. If you have a simple roof with a minimal number of roof penetrations (such as HVAC units, sky-lights, roof drains, through-wall scuppers, vent-pipes, posts, etc.), then your roof prices will be much less than if you had a more difficult roof with multiple roof penetrations and obstacles that require more roof flashing details. These roof penetrations require a great deal of professional manual labor and time, and slow-down the entire roof installation process.

Another factor associated with roof difficulty is the roof’s present condition, and presence of gravel and/or multiple roofing layers. These layers generally require removal and consume a lot of time because it is necessary to dispose of them. At the same time, roof removal must be performed quickly to eliminate the possibility of water penetration during the removal process.

Third cost variable: Indirect costs and material upgrades

Additionally, you can expect changes in roofing cost, depending on ease of access, roof location, and material options: As far as material options go, we offer a complete line-up of IB roofing membranes for residential and commercial installations. This includes: 50, 60 and 80-mil membranes in white and custom colors, as well as specialty membranes such as ChemGuard for restaurants, and IB Traditions (Architectural shingles pattern imprinted onto the membrane) and a Slip-proof IB DeckShield for walk-on flat-roof decks. We also offer a wide range of insulation options from 2-r fan-fold foam insulation to 20-r 3.3 inch ISO board and “tapered insulation” to create a slight roof pitch for drainage purposes.

Total Cost Concept

Consider the total installation price of the new flat roof. It will include: labor, materials, warranty and other factors. Roofing materials usually carry a manufacturer’s warranty period ranging from 5 to 25 years for commercial installation. Residential warranties will range from 5-15 years, while IB has the only Residential Lifetime Warranty in the industry. However, residential warranties are more complex, as many flat roofing manufactures will not warranty residential installations, or they fill impose certain requirements before they issue that warranty.

Any roofing job should also include a Labor warranty from the roofing contractor, and usually you can also purchase additional labor warranty from the manufacturer. IB Roofs offers an ‘NDL’ or No-Dollar-Limit labor warranty, which you can purchase as an additional ‘insurance policy’ for your roof.

Flat Roofing – thinking long-term

Most roofing contractors will warranty the water-tightness of the roof they install for the minimum period required by state law or building code. In Massachusetts for example, such minimum period is 2 years. After that, you are usually on your own. We find this especially troubling when someone chooses to install an EPDM or a black-rubber roof, which is especially popular among roofing contractors for its low materials cost. However, rubber roofs usually start to leak within 5 to 8 years after they are installed, due to failing seam adhesives. By this time your labor warranty has already expired and the cost of repair is on you – the owner.

We at CoolFlatRoof warranty our jobs for the length of the material warranty! We can do so, because we exclusively use IB PVC/CPA roofs, and we know that our roofs will NOT leak due to failing seams or other flashing detail.

Two: Overheads or Cost of doing business

Insurance Costs

It is in your best interest to hire a fully insured roofing company. However, adequate insurance coverage for a roofing company is very high: Worker’s Comp is usually 40 cents for each 1 dollar of payroll, or higher if the company had some incidents in the past. Liability Insurance is cheaper, but still it is one of the most expensive in the construction industry, due to possible damages if a contractor fails do adequately protect the building from water during or after installation.

Advertising: Market acquisition cost

Another considerable overhead for most roofing companies are the Marketing/Advertisement costs, as well as Sales-force commissions and office expenses. For many roofing companies, ‘market acquisition cost’ often range from $500 – $1500 per job. These include ‘Yellow Pages’ and news-paper ads, direct mailing, and Internet advertisement, such as Google or Yahoo Pay-Per-Click ads. As a result, you the customer, end up paying these expenses, or as we call it ‘marketing taxes’, that are not directly related to the cost of you roofing job.

We at CoolFlatRoof, do not spend any money on advertisement, except minimal expenses to run our web-site (around $100/year), so we will not charge you the ‘marketing tax’. Instead, we will provide you with the best materials, workmanship and warranty, for less.

Three: Ongoing repair and maintenance expenses

Ponding / Standing Water

While maintenance for most flat roofs is mostly due to the location of the building and surrounding conditions, one of the most frequent maintenance/repair expenses is due to ponding water. Positive drainage is preferable for any flat roof. However, the very nature of flat roof construction makes it often impossible to avoid ponding water accumulation, or it is too expensive to fix it. Ponding water can be eliminated in two ways: Installing Tapered Insulation, or creating a pitch, which is often impossible due to building design. Both are extremely expensive and will cost more than the roof itself, so eliminating ponding water is often out of budget.

While most flat roofing manufactures will void their warranty if there is presence of ponding water for periods of more than 72 hours after the rain, IB Roofs are explicitly warranted against ponding water and it is proven that an IB roof will keep your home or building dry even if you have big puddles of standing water for long periods of time!

Roof Repairs

As we mentioned above, many flat roofing systems will start to leak with-in 5 to 8 years after installation. Most roof leaks occur as a result of ponding water, failing seams, and to a lesser degree, faulty installation. Other factors affecting performance of a flat roof are weather conditions and devastating UV rays of the Sun. This is very true in the New England. We have hot summers and cold winters, and the temperature can dramatically change in matter of hours. Refer to our flat roof repair guide for more information on how roof leaks occur, and what your repair options and costs will be.

In most cases these repairs will be an out of pocket expense for you, as the usual warranty period will be long over by that time. We on the other hand will uphold our warranty after the usual 2-year period, if the leak happens. However, we do everything right the first time so there is usually no need to repair our roofs!

Four: Energy costs/savings

Cool, energy-efficient roofing form IB

Unlike most conventional roofing systems such as Epdm black-rubber, or Asphalt/Tar based BUR roofs, which attract, store and transfer solar heat, white IB Roofs reflect as much as 90% of the solar heat, and carry a Cool Roof certification! Even if you choose one of IB’s color choices, they are also certified by the Cool Roof Council, by implementing highly reflective color pigments. This will save you tremendous amounts of money in reduced HVAC costs. IB roofs act as a complete thermal barrier and increase the R-value of your roof, thus also reducing your heating expenses in the winter. By adding more insulation you will further increase the thermal qualities of your roof.

Conclusion

An IB Roof is the best choice when it comes to flat roofs. An IB Roof has the lowest Total Cost combined with unsurpassed quality and longevity. If the need to repair your IB roof ever arises, such repairs can be performed even 20 years from the day of installation, with IB’s unique Hot-Air fusion welding. It is however highly unlikely, unless there is unforeseen physical damage to the membrane. Expect not to have to repair your IB roof, ever!
An IB Roof will eliminate your ponding water problems and you will avoid expensive pitch-change. IB will also save you money every year by reducing your energy cost, and you will be covered by the Industry’s Best warranty!

If you are looking for a sustainable, long-lasting roofing product for your home or business pitched roof, the Metal Roof will be the perfect choice for you. Known for decades of leaks and corrosion free service, Aluminum metal roofs are becoming the prime choice for quality and longevity oriented home and business owners looking for a new roof. With its Cool Roof properties and permanent design, metal roofs will outlast any conventional asphalt shingles roof. Metal roofs are light-weight, and do not require any structural modifications.

Flat Roofing systems: The purpose of a flat roof or any roof for that matter is to keep your home or building safe and dry. The roof MUST protect your investment from the elements such as rain, snow, and even the sun’s heat. However, many flat roofing technologies on the market today have some major, inherent drawbacks that have origins in their design. In fact, most flat roofs fail to serve their main purpose just a few years after they are installed.

You are presented with so many choices for a flat roof and every roofing contractor will tell you their product is the best. But which one do you choose and how do you know that you are getting the best deal? Here we have summarized the most common and ‘popular’ flat roofing choices. You can be the judge and decide which is best for you.

Benefits of flat roof construction:

There is a common misconception among many home-improvement contractors and residential builders / architects that flat roofs = problems. The truth is that flat roofs are very convenient, easier to build, and cost less than pitched / sloped roofs. In some cases, a flat roof is the only way to go, for example, when you have a large size building. Building a reliable pitched roof in those cases will require extra engineering to accommodate for additional structural weight.

Flat roofs are also convenient for installing large HVAC equipment that otherwise would have to be installed on the ground. You can also use flat roof as a roof-top deck, patio or penthouse. Green roofs are also gaining popularity with environmentally conscious companies and organizations.

When you compare all the construction costs and environmental benefits, flat roofs by far surpass any sloped roof, for which the roof products of choice are oil-based asphalt shingles. These asphalt shingles end up in our land-fills every 12-15 years, and yet more and more of them are produced.

Limitations and Disadvantages of flat roofing:

Flat roofs also have a number of disadvantages. The main one is the fact that there is no slope and all the water/snow sits on the roof. While water can be taken care of with proper drainage, snow will sit on the roof until it melts. This requires the engineers / architects to implement building components with a higher structural load. Another disadvantage that haunted flat roof installations for over a century is ponding water. Until the invention of single ply membranes such as an IB roof, there was no effective and economical way to eliminate the leaks caused by ponding water. That had to be taken care of in the initial design/construction stage. Creating a slight pitch and multiple drains was required, and still ponding water caused over 75% of all flat roof leaks.

Now the ponding water problem is solved by either implementing a slight pitch to the roof – such as in ‘space metal buildings”, using tapered insulation to direct water flow toward drains and with the creation of IB PVC / CPA roofing with hot-air welded seams, ponding water is no longer a problem in small quantities. It is still necessary to have adequate drainage system, since a lot of ponding water can cause structural damages to your house or building.

Types of flat roof: Modern and Outdated roofing technologies.

Outdated (Multiple-Ply Roofs) – some are over 100 years old:

• Build-Up Roof (BUR)
• Tar & Gravel
• Bitumen (Modified Bitumen)
• Rolled Asphalt (usually a “single-ply” install, sometimes uses tar-paper as base ply)

Modern (Single-Ply Membranes)- created within last 30 years:

• IB Roof (PVC roofing) – IB PVC roofing membrane is one of the best low-slope and completely flat roofing products available, and that is precisely the reason why we only install IB roofs. With over 30 years of spotless reputation and leaks-free performance in many different climates – from Alaska’s frigid north-lands to Hawaii’s tropical paradise, IB roofs are protecting the buildings and everything inside, without a single material failure since 1978.
  
  IB roofs still feature the same chemical formula as its original design, and with hot-air welded seams, will maintain complete water-tightness over your roof.
• Epdm Rubber Roof – a widely used flat roofing material, mainly popular among contractors because of its low price and no special equipment needed to install the rubber roof. Still, rubber roofs are very prone to leaks, as the seams are glued together, and adhesive tends to break down within 5-7 years. Also in the residential roofing market (and not so much in commercial) there are too many contractors who will install rubber roofing products without proper knowledge and training. As a result, we often go to rubber roof repair service calls to fix problems caused by poor workmanship, often on fairly new roofs.
• TPO Roofing – a single ply thermoplastic roofing membrane similar to PVC roofs from a first glance. But as you start digging, you’ll find numerous problems with TPO roofs, mainly as a result of manufacturers skipping on adding important ingredients into formulation of the TPO membrane, and as a result, quietly scrapping as many as three major generations of the product.
• SFR – Sprayed Foam Roofing (not a single-ply)

Part I: Inferior and outdated flat roofing technologies

These are very common on older buildings, although many newer buildings also have these systems installed. They are rarely installed on any commercial building today. However, they continue to be produced, and many roofers still install them on residential and small commercial roofs. This is particularly due to their low cost of material, and roofers’ lack of experience with BETTER solutions. It is sad that there are some decent roofers offering such an inferior product to their customers. I often hear something along the lines of: “I’ve been doing ‘torch-down’ for 20 years, and it is the best” – very sad – so we will briefly describe them, without getting into details.

BUR / Tar & Gravel / Torch-down: Multiple-ply roof where each ‘tar-soaked’ ply is applied with a torch (yes, open flame on your roof!), or hot mopped (preheated tar transported to the roof and applied with a mop). Gravel goes on top of this ‘sandwich’ mainly as a protection layer from foot-traffic and sun’s devastating ultraviolet rays. There are many deviations from the above procedure, but they are all within a close range of similarity.

Modified Bitumen: It is also applied with a torch in a similar manner described above. It is however a different material than tar. Modified bitumen has rubber and elastomers added into the formula, so it is stronger and more flexible.

Rolled Asphalt: Similar to asphalt shingles – tar paper is saturated in asphalt, with crushed stones glued on top of it. Rolls are installed in an overlapping pattern, with cold-mop application and nails to attach it to the roof deck. Overlapping seams are sealed with tar.

Problems associated with flat roofs:

The nature of flat roofs’ problems is just that they are flat. Water does not run off the roof. Proper drainage must be in place to get rid of water accumulating on a roof. Usually older roofs are not leveled, so water puddles will appear here and there after every rain, and just sit there until it dries out. This is called standing or ponding water. Most roofing systems were not designed for ponding water. In fact, most manufacturers of the roofing systems on the market today, will void out the warranty if there is ponding water on the roof (we will get to this issue later). Other major problems for flat roofs, are penetrations such as skylights, vent or exhaust pipes, chimneys, roof hatches, drains, etc. However the biggest problem with flat roofs is the seams, because they are the most common areas where leaks occur.

Seams:

Seams exist on every flat roof (except tiny ’6×10 porch-type’ roofs, which can be covered with a single sheet of roofing membrane), and are usually put together with some sort of adhesive. After a few years the adhesive breaks due to severe weather changes (here in New England, temperature can change 25 degrees or more, in a matter of one day). Another major factor affecting seams’ adhesive is condensation, which always occurs underneath the roof covering. Condensation expands both in the winter and summer. The most dramatic expansion of condensation happens in the winter time when water freezes, expands and breaks the seam. The same happens to our roads. Think of all the potholes you drive over. Those too were caused by water freezing. In the summer water heats up and also expands. When you see bubbles on the roof surface, it is the water vapor lifting the membrane. The third major factor is actually quality of workmanship and the adhesive itself. For different roofing systems the process is different, but most of them share the same shortcoming – the need for using adhesives, be it glue, hot tar, liquid resin, etc. Adhesives are also required to flash any roof penetrations listed above, but here the workmanship is actually more of a factor than the adhesive.

Conclusion – let’s get real.

It is a shame that in the 21st century we are still using 19th century technology. Even more so, because nearly 50% of roofers in the on-line construction forums will advise you to choose a clearly inferior roof. These heavy and dirty roofs, heat up to 170 degrees and make your AC run like crazy in the summer. These very roofs start leaking prematurely and are impossible to fix. Why would some one acting in good faith actually recommend these? The answer is obvious – they don’t know any better. Fortunately there is ONE modern, technologically advanced flat roofing solution available on the market today – IB Roof. In fact, this solution has been around for a few decades now, and has a proved track record of 30 years of leak-free service!

Imagine that you no longer had to worry about your flat roof – no more leaks, no more repairs, no more headaches. IB Roof provides a solution to all known flat roofing problems.

What is IB Roof?

IB roof is a single-ply polyester-reinforced CPA/PVC membrane. IB’s original design comes from Europe, where engineers of the Post-War era were faced with massive industrial and residential re-building. They had to create a roofing product that would last a long time while minimizing energy and maintenance costs. In 1978 IB Roof Systems took the original design improved it with the latest technological know-how’s and created the ultimate roofing solution for both residential and commercial/industrial flat roofing market. In fact IB’s formulation has not changed since 1979.

IB Roofing membrane features unique design, incorporation 100% virgin PVC in its formulation as well as ’50/50 equal thicknesses’ Top/Base film laminated to polyester reinforcement scrim (notice that competition’s top film thickness does not exceed 35-40%). Top film and it’s advanced formulation, is what makes IB’s membrane long-lasting, by resisting the destructive powers of U.V. rays as well chemicals and substances that are normally present on flat roofs, and cause the degradation of the roofing material, resulting in costly leaks. We have an exceptional track record installing IB Flat roofs in Massachusetts, Rhode Island and Roofs in Connecticut with leak-free installations on commercial and residential IB flat roofs.

IB Roof Installation Video – Hot-Air Welding

How is IB different? IB’s unique installation method

All seams and flashing details of IB flat roofing system are Hot-Air welded. This process incorporates precision welding equipment designed and produced in Switzerland – the home of world’s best watches such as Rolex, Rado and others – such equipment is widely used in civil as well as US military applications.

Hot-Air welding creates a physical bond between two separate sheets of IB roofing membrane, effectively making them on piece. Unlike chemical bonding where glues and/or other types of adhesive is used, hot-air welding eliminates the possibility that seams will come apart due to adhesive de-lamination or chemical break-down.

IB gives you a peace of mind with the Best Warranty in the industry!

IB Roof Systems is so confident in their product that it is covered by a 100% non-prorated Residential Lifetime Warranty and up-to 25-years Commercial Warranty. IB roofs installed over 25 years ago are still performing leak-free, and save their owners money in repair and maintenance as well as energy costs.

What make IB Roofs so unique?

• Long-lasting, worry-free roofing
• Complete Flat Roof-System
• Energy-Efficient Cool Roof
• Designed to withstand Ponding Water
• Easy roof repair in any weather

Longevity:

IB Roofs have been in service since 1978 with zero material failure. The key to such an amazing performance is the way the overlapping seams are attached. Unlike conventional roofing systems, where adhesive is the key component as well as the major flat-roof failure factor, IB’s seams are Hot-Air welded by precision Swiss-made welding equipment. Once the seam is welded and cured (which takes about 1-2 minutes), it cannot be broken without tearing the membrane. In fact IB seams are stronger than the membrane itself. Hot-air welding ensures that seams will never come apart, thus the integrity of the roofing system is consistent through-out its life-cycle.

IB Roof: a true energy efficient Cool Flat Roof!

The ever-rising energy costs may put a big dent in your budget. Air-conditioning in the summer may be just as expensive as heating in the winter. This is where IB roof really excels with its Cool Roof qualities. IB’s white membrane reflects up to 90% of solar heat. What it means for you?

On a 85-degree day, a regular black-color flat roof such as Epdm, will heat up-to 170-degrees and will transfer that heat into your house or building. IB will only go to mere 91 degrees, saving you tons of money in direct costs as well as making a small, yet important difference for the environment, as over 45% of US’ electricity is produced by Coal-burning power plants polluting our air and causing global worming. In the winter, IB roofing membrane in conjunction with the insulation will keep your place warmer as it is a Heat barrier, so you’ll be saving money year round.

IB Roof – the only 100% integrated flat roofing system on the market.

Flat roof leaks mostly occur either at the seams or around roof penetrations such as vent pipes / drains / HVAC curbs / sky-lights, etc. Most flat roofing systems fail to address these issues appropriately, and instead rely on some sort of adhesive and flashings produced by a third party, often with questionable quality.
IB Roof is the only flat roofing systems that comes complete with all flashing detail parts manufactured in house, and giving you the quality and piece of mind.

IB provides a wide range of flashings made from the same CPA/PVC material as the as their membrane, which were designed to accommodate every possible flashing detail on the roof.

Just to list a few:

Inside and Outside corners made for HVAC curbs/sky-lights/chimneys, etc.

Through-roof drains designed for commercial, residential and restaurant application. These drains can be a simple drain-liner to sophisticated aluminum body drains with over-flaw protection and a leaf/dirt guard.
A variety of vent-pipe boot flashings that come in sizes from 1″ to well over 1 foot in diameter, to accommodate for any size of ventilation or hot-stack pipes, electric posts and other roof penetrations.
Integrated PVC Air-Vents made of industrial-grade PVC were designed by IB to provide adequate roof ventilation for mechanically attached installations.
Many more standard and specialty flashings such as Through-Wall drains, Custom Scuppers, and even PVC-coated drip edge all make IB a completely integrated flat roofing system. These flashings are all welded together right to the IB roofing membrane with hot air, effectively creating as single-piece roof blanket, which is non dependent on unreliable adhesives.

Ponding water – leading cause of flat roof leaks. Not a problem for IB Roof

Ponding water is the leading cause of leaks on the flat roofs. In MA, RI and CT, as well as other parts of the US, with the old construction methods of 20th century, there are now thousands residential and commercial flat roofs exposed to leaks. Ponding water creates puddles on your roof that have no way to be drained due to short-comings of the original design and impossibility to create new drainage methods. This standing water destroys your roof by breaking the seams, saturating the insulation , and rotting the wood decking. Once water enters inside the building, it damages the structural components, ceilings and drywall, flooring, as well as electrical system. The combined costs of internal repairs due to roof leaks, may by far exceed the cost of installing a new IB roof.

While majority of roofing systems are not warranted against ponding water that occurs for more than 72 hours, since their seams cannot be permanently sealed with adhesives, IB includes explicit Ponding Water warranty with all of its roofing membranes! IB can do so because their seams – while being the WEAKEST point of other, conventional roofing systems – are actually the STRONGEST parts of IB flat roofs, and are designed to withstand constant ponding water.

Ease of Repair: IB will not Cure, and will remain weldable for decades.

If your IB roof gets some sort of damage like a falling tree or from something sharp dropped on it 5, 10 or even 20 years after it was installed, repairing it will be a breeze. All that will have to be done is a small patch welded over damaged area – it’s that simple! IB roofing material will not cure with age, it will not become brittle. IB roof can be repaired even in the sub-zero temperatures of the winter, when other roofs may not be repaired due to adhesive freezing before it is applied. IB roofs are time-tested to remain weldable for over 20 years not only in the lab environment, but in the real life. Harrisburg School district got all their schools a new IB roof over 25 years ago. While these remain leak-free, IB tech representatives went out and tested those roofs for weld-ability. The result – it is still just as elastic as it was in 1979, and no problems re-welding them.

So if you have a mechanical damage or want to add a sky-light or an HVAC unit to your roof after it was installed, your roof will not give you any troubles.

IB specialty membranes: Residential and Commercial.

IB flat roofing membranes were originally designed and tailored for the needs of commercial flat roofing market, addressing strict reliability standards. Soon it became obvious that residential flat roofing market had to be addressed a well.

IB’s white single-ply roofing membrane is great, energy efficient roof. However sometimes, architect will specify a certain color, or building design will call for heavy roof traffic. IB addresses all you needs with their custom and specialty roofing membranes while keeping their best qualities. IB carries over 6 standard colors, as well as the ability to create over 450 different custom colors for commercial and residential applications.
