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 if you are looking for a long lasting, durable, leak free, energy efficient and low maintenance roofing membrane, an IB PVC Roof is the best choice.

IB is a premium product and costs more than most other flat roofing materials. Here we review flat roofing cost structure and, IB Roof prices and packages that we offer in Massachusetts and surrounding states ( CT, RI, NH, ME and VT).

Flat Roof Replacement Cost: Residential and Commercial

At some point, there comes a time when flat roof patches stop working and it needs to be replaced. Installation price from every roofing company also includes that company’s overhead or cost of running the business. 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.

Flat Roofing Insulation

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, you will contribute to the reduction of carbon monoxide emitted into the atmosphere. Moreover, by using recycled insulation, you save space in our nation’s landfills, another invaluable benefit to 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.

Another option you have is 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.

Green Roofs – Benefits, Design and Cost

The concept of green roofs, or roof-top gardens that create healthier cities is great, and fortunately it is not just for enthusiasts. However, despite their many benefits to the environment and homeowners, green roofs still face many obstacles in becoming main-stream. Some of those obstacles are technical and, some (the most important ones) have to do with the price tag associated with a green roof.

Green Roofs carry numerous benefits from reducing the heat-island effect and extending a roof's life span, to creating a great aesthetic feel, which enhances productivity of office workers, and ultimately creates a healthier city.

We will review green roofs, not only from the Eco-friendly perspective, but also from a roofer’s point of view, as it is the roofer that makes green roofs work. We’ll also discuss recent technological breakthroughs in the green roofing industry, which have to do with simplifying design, installation, and greatly reducing costs.

Cost of Green Roofs

Green roofs are expensive – no doubt about that. The Main reason being the relative difficulty of building and maintaining a green roof, while making sure the water-proofing membrane is intact, and performs for its specified life-period. Another reason is that all the components of a green roof (of which there are many) are expensive, and only a handful of suppliers offer them. Green Roof vegetation is also a concern, as these plants must be able to survive in a limited amount of soil and if a drought hits, these plants might not survive. It may also be necessary to set up some kind of a sprinkler system to maintain the required moisture level.

When all is set and done, a green roof will create a beautiful roof-top-garden and should significantly increase, if not double the life of your roofing membrane, as it protects the roof from the sun and the elements. A green roof will also make your building a lot cooler, as it absorbs most of solar heat.

Technical (installation) issues

To reap all these benefits of a green roof, it is of the utmost importance to use the best available flat roofing membrane, such as 80-mil IB Roof and to have a quality installation performed by a certified flat roofing installer. Just imagine that your new green roof is installed, and some time later it begins to leak – now you have to disassemble it: remove the vegetation and soil, moisture retainers and water-flow base, while the leak may not even be where you think it is. That is why from the installation perspective everything must be installed to the highest standard; all seams must be checked and double checked in order to ensure a leak-free, functioning roof.

IB Roof and GreenRoofBlocks

IB Roof and Green Roofing Blocks create a perfect combination for a long lasting, easy to maintain and inexpensive green roof.

To make the installation and maintenance of a green roof as simple and inexpensive as possible, we chose to combine our IB PVC roofing products with a simple, modular approach of Green Roof Blocks. These green roof sections come in 2×2′ aluminum boxes with specially formulated light-weight soil. Green Roof Blocks offer a quick installation, ease of roof repair – if there is ever a need to do some roof maintenance, all you need to do is to simply lift up the sections where you suspect the leak may be. Green Roof block is also the most cost-effective green roof you can find. Vegetation can be planted and grown before the roof is installed, or right on the roof-top.

Our Customer’s Comments:

CoolFlatRoof installed an IB roof on a flat section of my house. They did an excellent job. I had problems for years with leaks and would hire someone to repair it, but after awhile it would leak again. It had never leaked since Leo and Alex put this excellent roof on my house. It also seems to be more insulated: warmer in the winter and cooler in the summer. Thanks guys. I recommend you to everyone who mentions a roofing problem. – Jack from Providence, RI

Residential Flat Roofing – Forget About Your Roof Leaking With IB Roofs




  • Does your low-slope roof leak due to Ice Dams problems? Does your ridge vent leak, or did you have to completely remove the ridge vent to stop leaks? Poor ventilation and attic insulation is causing your ice dams, but now you can solve this problem efficiently and economically.
  • An IB PVC Membrane is a solution that will keep your home, probably your biggest investment, watertight and ice dams free for decades to come!

Residential IB Cool Roof in Wallingford, Connecticut. This 80-mil grey roof perfectly blends with the house, keeps the water out, and homeowners happy. No more patching or repairs, no more worries!

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 hiring 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 cause 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.

IB Membrane Solves Ice Dams Problems

An IB membrane is a 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 from entering your attic space through the holes in the ridge vent, while allowing the warm air to escape the attic. Check out our special Low-Slope roof ridge vent assembly, which improves your attic ventilation and eliminates leaks!

Leaking Roof Decks – Why they leak and how to fix problems:

Many homes in New England have 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 leaks.

Most roof decks leak because they are typically made of flat roofing materials, that were created over a century ago, and were not designed for use as roofing for residential homes and living areas.

Another reason is the original design flaw implemented by architects and/or builders, who have no experience in flat roofing, and do not have appropriate roofing technology to use.

Avoid conventional flat roof materials – they will leak!

A properly waterproofed deck should never need repairs or replacements. Even with a floating wood deck on top, you should never have to do maintenance or deal with leaks.

This CANNOT be accomplished with rubber roofing (EPDM), becuase rubber is a GLUED system. Glue breaks down with time, and even faster, when you add water to it.

However, using IB / PVC Cool Flat roofing membrane, you can waterproof your deck and forget about!

Here is what a well done roof deck looks like:

What causes flat roof decks to leak

Ponding Water Leaks

Very often you can find ponding water accumulating on these deck roofs. The majority of flat roofing systems 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 penetrations 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 may sometimes result in partial or complete re-framing of your roof and/or support walls.



Creating a leak-free Roof Deck with IB roofing systems

Damages caused by leaks are very expensive to fix. Yet, you can easily solve this problem 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 an IB Roof, you will never have to worry about leaks again and you could finally regain full use of your roof deck or patio.

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

Assembly Type 1:IB DeckShield

A fully integrated waterproofing membrane system designed for use on walk-out roof decks. DeckShield is highly slip-resistant, and not only complies with, but also exceeds ADA (Americans with Disabilities Act) requirements. 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.

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, invite your friends and family for a cookout, enjoy a cocktail, or watch the stars.

IB DeckShield Roof / Deck Assembly and Installation

DeckShield is easiest to install on new construction homes. 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.

Rubber Roofing (EPDM) – Pros and Cons of Using Rubber Flat Roofs

Rubber roofing (EPDM single ply membranes) is the most common flat roofing system in New England (MA, CT, NH, RI, etc.) and the rest of US flat roofing marker. Most people refer to a flat roof as a “rubber roof”.

The main reason for such popularity of rubber roofs is the lower initial price tag. However, rubber roofs have many inherent problems.

These problems cannot be solved by technology, because of their design, as well as issues with unprofessional contractors claiming to be “rubber roofing pros“.

However, you can do the repair yourself, saving hundreds of dollars, and avoiding shady, unqualified contractors. Here is how to do it:

Homeowners with flat roof homes often find themselves in a situation where their roof starts to leak rather unexpectedly – i.e. only after a few years since it was installed.

This for the most part happens to homes that have a rubber roof on them. While most flat roofs will only last 10-15 years, older systems such as Tar & Gravel, BUR (built-up) and in some cases Modified bitumen roofs.

These roof types are usually installed by roofing contractors that are somewhat specialized in their field of work – these are “the old-timers”, or former union guys that decided to try their luck working for themselves, and they actually went through special training and have years of experience.

The problem is that roofing systems they install do not last long for many reasons outside the scope of this article. By contrast, most rubber roofs are installed and repaired by roofers that have no special knowledge or training, they take on EPDM roofing jobs, because they are seemingly easy, inexpensive to install and require no special expensive equipment.

If you have a leaking rubber roof in Massachusetts, Connecticut or Rhode Island we can give you a roofing price quote to replace your roof with our flat roofing material of choice – a new, lifetime PVC Flat roof manufactured by IB Roof Systems. We can also repair your rubber roof at a relatively low cost, using only the best materials that rubber systems have, and extend the life of your roof by a few years. One example of such materials are peel-and-stick flashing and seam tapes. We do not use black rubber glue as it is outdated, and leaks much faster.

Why Are Rubber Roofs So Popular?

Rubber roofs (EPDM) are the most used flat roofing products in the US / Canadian commercial roofing market. They we first put in service over 40 years ago, and since gained popularity among roofing contractors and their customers. The reason for such success lies in the condition of the flat roofing market at that time and the available alternatives.



Back in 1960’s oil was still very cheap, it was more than a decade before the oil crisis of the 70’s and there wasn’t that much demand for oil. The oil refining process was far from being efficient and the industry was looking to get rid of many by-products of the oil refining process.

At the same time, the flat roofing industry was the same as at the turn of the 19th century, and the most common product to use on a flat roof was either a BUR (built-up roofing, using multiple layers of tar paper, saturated in hot tar or hot asphalt) or Tar & Gravel roofing, which was essentially a BUR roof with gravel added for additional protection. Flat roofing technology has not changed for 100 years and contractors needed a new, easier to install and cleaner product, hence, EPDM rubber roofing system was born.

EPDM consists mainly of oil based by-products with some modifiers and stabilizers added to extend its service life. Rubber roofing was cheap to produce, easier to install than conventional (BUR) roofs, did not require any special equipment to put it down and the membrane could potentially last for decades, as it was UV stable and did not break down when exposed to the weather.

Because rubber roofing was cheap, quick to install, and offered a potentially long service life, and with lack of any opposition from better roofing products, it quickly became the king of flat roofing and the pioneer of the single-ply flat roofing market.

PART 2: Avoid using “roofing pros” who do not specialize in flat roofs:

Below we will explain that one of the major problems with rubber roofs is the poor workmanship of roofing contractors who install and repair them. We will demonstrate how many roofers are “trained” in installation of EPDM single ply roofing systems, as well as results of their work (our Horrible Rubber Roofs series).

The Truth About Residential Flat Roofing Market and Contractors

Rubber Roof Contractors: It is unfortunate, but most residential flat roofs are installed by roofing contractors that specialize in asphalt shingles. Since they can easily purchase rubber roofing materials from their roofing supply warehouse, and are not required to be certified installers, nor do they need any special training or equipment, they will often undertake such projects to keep their crews busy.

These are just some roof inspections that we did in the summer / fall of 2011. Look – even commercial roofs are not immune to hack roofers and faulty materials (like rubber roofing), but in residential, this is much more common.

Contractors’ Lack of Knowledge and Lack of Training

To get a quality rubber roof installed, it usually has to be done by a commercial roofing company that specializes in flat roofing. However, it is often the policy of such companies not to work with residential customers, for which there are many reasons. These contractors work with large commercial and institutional customers, employ union workers who are trained roof mechanics, specializing in their particular niche. For example, a commercial roofing contractor will have separate crews doing metal roofing or slate – these guys are “roofers”, and yet another crew doing flat roofing ONLY – these are “roof mechanics”.

A residential roofing contractor usually employs just roofers, who are good at what they do all day long – install asphalt shingle roofs, and often do not have a clue about how flat roofs work. When they get a potential client with a flat roof, they go to their supplier, ask what supplier has for flat roof, and the salesman at the supply warehouse TEACHES the roofer how to install EPDM rubber. This is not creative fiction or a product of my imagination – I see this happening nearly every time, when I come in to the supply store to get something.

“Trained rubber roofing installers”: If you are lucky, you may get a roofer that has received some sort of training about rubber roof installation. For example, one of my suppliers, provides installation training programs for their roofing contractors who install only asphalt shingles. The idea behind such training seminars is to increase awareness and solicit sales of more roofing products. A manufacturer technician provides a sample installation on a 8×8 feet demo stand.

Below is an example of such “hands-on rubber roofing training”.

epdm rubber roof installation

As you can see, the roofers just sit around the demo stand while the MFG Installation technician shows them what to do. The whole demonstration took about an hour and a half, and covered thing like installing flat roofing insulation (ISO), adhering rubber to the ISO board, flashing a sky-light / chimney penetration with un-cured flashing material, installing the membrane up the vertical wall, cleaning & priming seams and installing seam tape, installing drip edge and a tape to seal the drip edge fasteners, and installing termination bar. In the same 1.5 hours we’ve also “learned” how to correctly apply yellow glue – membrane adhesive, seam primer – seam & flashing glue and how to install these systems in the winter, while violating manufacturer’s installation specs.

rubber roofing

Out of 25 or so roofing contractors present, there were about 15 or so questions particular to the installation details. 7 of them were asked by me! Bear in mind that I already knew how to install a rubber roof and attended the event to talk to my salesman, representatives of the metal roofing manufacturer and for free refreshments ūüôā



In any case, each one of those 25 or so roofing contractors, willing to learn a new, and very complicated roofing system, asked an average of 0.3 questions about this system.

Rubber Roofs for Residential Customers: It was clear that my supplier and the roofing representatives were selling to Residential Roofing Contractors. Not once did they mention roof-top HVAC units, roof hatches, elevator shafts, gas/electrical pipes, roof drains, etc. They did however insist that the rubber is a good choice for a low slope shed dormer (without mentioning the poor low slope roof ventilation and ice dam prevention associated with shed dormers). They also mentioned that rubber is a good choice for a flat roof decks and patios.

Single-Ply Flat Roofing Membranes – PVC, TPO & EPDM Rubber Roofs




In our overview of Flat Roofing Technologies: Part I РBUR, Tar & Gravel and Modified Bitumen, we discussed the older and in many ways inefficient types of flat roofs, that are not only outdated by today’s standards, but also have a short life cycle expectancy. Moreover, they pose numerous obstacles when it comes to repair, as discussed in our Flat Roof Repair guide.

In Part II, we will take a look at the newer, more advanced roofing technologies, and explore the advantages and disadvantages of each single-ply roofing technology commonly used today.

What is single-ply flat roofing?

There is a lot of confusion about single ply membrane roofing. Many people think that any ‘single ply’ is the answer to their¬†flat roofing problems. This however is far from being the truth. In reality, single-ply roofing membranes have only one thing in¬†common – that is: they are single ply, or just one layer of membrane that is a waterproofing barrier. The similarity stops there.



Membrane formulation, or the components a membrane is made of, marks the biggest difference between different single-ply products. Single ply membranes come in various widths, ranging from 6 to over 18 feet. In theory, the wider the membrane is, the less overlapping seam you have, thus reducing the possibility of leaks. The reality is different however, and most commonly used membranes do not exceed 10 feet in width.

The most crucial aspect to the reliability and longevity of single ply roofs is the method of attaching overlapping seams together. That is where 99% of flat roof leaks occur. Therefore, having permanently attached seams is the most important factor in the longevity of a flat roof installation. We will discuss it in more detail as we review different single ply roofing technologies.

Single-ply Membrane Installation Methods

Single ply membranes are installed either as fully adhered or mechanically attached systems, depending on each roof’s condition, installer’s preferences, and other factors. Underneath the membrane, there is usually a separation barrier¬†and/or some sort of insulation board. Most common insulation is ISO or EPS foam board. Both types have an R-value ranging from¬†4-R to 6-R per 1 inch of insulation thickness.

Mechanically attached IB CPA/PVC Membrane on a roof of residential house in  Providence, RI.

Mechanically attached IB roof with hot-air welded seams, ensures that your roof will  be leak free for many years to come, and high wind uplift will not cause damage to your building.Mechanically attached installation uses heavy duty screws and barbed plates to hold the membrane down tightly, and is not affected by possible ISO de-lamination. The membrane is attached using 12″ O.C. pattern with perimeter sheets attached 6″ O.C. This ensures that even the hurricane-type wind will not tear off your roof. Mechanically attached installation method does not require the use of heavy and expensive ballast, and is a preferred choice, if your building is located in a high-wind area, such as along the coast line or on a high hill.

Fully adhered single ply membranes are glued to the fiberglass sheet, laminated to both sides of the ISO insulation, which is in turn attached to the roof deck. While quick and simple, the fully adhered method has one serious disadvantage. If condensation forms underneath a roofing membrane, which often happens and may be caused by improper ventilation of the roof deck, it will ‘de-laminate’ the ISO board and/or adhesive that is holding membrane in place. If the membrane becomes loose, it is prone to wind blow-off, which will leave your roof unprotected. Results of such blow-off will be catastrophic not only to your roof, but to the entire building. While this is rarely the case, it is still a possibility – a gamble you might not want to take.

More common problems with fully-adhered single-ply flat roofing systems (Mostly EPDM rubber) are defects in glue/adhesive application that cause bubbles, badly glued seams and as a result, a very unpleasant view and more often then not, roof leaks. The image bellow demonstrates a defective EPDM rubber application.

Find out more information on why you should avoid installing EPDM rubber roofing on you home and how residential roofing contractors are trained to install rubber roofs.

Three most common single-ply roofing systems

Today, when it comes to flat roof replacement, single ply roofing is the top choice. More and more contractors are switching from old systems, such as BUR, Asphalt, and Tar & Gravel to single-ply membranes, which are easier, safer and faster to install. Single ply roofing installation does not require torching, used in Modified Bitumen installation, and therefore there is no fire hazard/possibility to burn down your home / business.

There are 3 most-used single ply membrane systems present on the market today: PVC/CPA, EPDM rubber and TPO. Bellow, we provide a brief summary of each of these systems.

PVC (CPA) Roofing

  • PVC – Polyvinyl Chloride – a thermoplastic membrane, utilizing a reinforcement scrim between the two plies of equal thickness (IB roof only). Top ply contains Cool Roof pigments, UV stabilizers, and other components to extend the life of the membrane. Bottom ply contains PVC ingredients to provide consistent weld of top and bottom plies and fillers.¬†Material Warranty Period: Up to 25 years Commercial / Lifetime Residential. PVC life expectancy: 30+ years. The reason for PVC’s superior durability and longevity are the seams, which are hot air welded and as a result will be impervious to leaks and will never come apart.
  • Special Notes: For a complete overview of IB flat roofing products for residential, commercial and restaurant use, as well as installation method and roofing accessories refer to our IB Roof products page.
  • Learn more about IB’s outstanding single ply flat roofing membrane, its advantages, and many choices for Residential,¬†Commercial and Restaurant use.

TPO Roofing

  • TPO – Thermo Plastic Olefin – a thermoplastic membrane utilizing a reinforcement scrim between the two plies. 35/65 % thickness for top & bottom ply respectively. Top ply contains Cool Roof pigments, UV stabilizers, and other components to extend the life of the membrane. Bottom ply contains TPO ingredients to provide consistent weld of top and bottom plies and fillers. Note that the top ply is about half the thickness of the bottom ply. Yet, the top ply is the one that makes the roof long-lasting. IB PVC has a 50/50 or equal thickness of top/bottom ply.
  • Material Warranty Period: Up to 20 years Commercial / None for Residential. TPO roof system life expectancy – 7 to 20* years. Like PVC roofs, TPO systems also use the hot air welded seams technology to make the roof durable and leak free. However, problems with the membrane formulation, are a source of many issues. You should know that there is not a single TPO installation in existence in the USA, that was produced in North America and is older than about 15 years. Therefore it is unknown how long a TPO system will perform without any leaks*.
  • Special Notes: * TPO roof systems are under continuous development by numerous manufacturers, who constantly change the TPO formulation to achieve the lowest cost with acceptable performance. While it is understandable that businesses always look to save money and to reduce costs, this ongoing TPO development process is being conducted, often at the expense of the roof owner. A TPO roof from the same manufacturer will most likely NOT be the same as the one produced a few years before or after. Also, the quality of different batches of TPO membranes may be questionable, as some TPO producers release the product to the end user without getting the UL and similar approvals/certification, as the formulation changes too often. Refer to our comparison article of PVC vs. TPO to find out more about the TPO problems / short-comings.

EPDM Rubber

  • EPDM Rubber – Ethylene Propylene Diene Monomer – a rubber-like black membrane, usually non-reinforced. Most common application method is a fully adhered (glued down) membrane with glued seams / flashings.
  • Material Warranty Period: Up to 40 years Commercial / None Residential. EPDM roof system life expectancy – 10 to 15 years. Although the material warranty goes up to 40 years for a 90-mil Epdm from some manufacturers, it does not cover the seams. Failing seams are the main cause of EPDM roof leaks, followed by ponding water, for which EPDM has no warranty either.
  • Special Notes: EPDM is the least expensive single ply roofing type and requires no special equipment to install it (unlike PVC and TPO which require hot-air welding equipment) and thus is the first choice for contractors entering the flat roofing market and asphalt shingle roofers, who ‘install rubber here and there’. Although many commercial roofing companies also use EPDM, they usually do not perform Residential installations so many times a home owner deals with a Part-Time flat roofing company.

Badly installed Rubber Roof:

EPDM roof bubbles - what happens when a wrong adhesive is combined with wrong roofing membrane and a wrong installation method.
Please note that there are many manufacturers of all three types of roofing, and each has their own formulation / manufacturing process / warranty conditions and periods, etc. Therefore we only provide a general summary for each of those roof types. Also, since our specialty is installation of IB roofs, when we use the term PVC or CPA we refer to IB PVC Roofs (CPA or Co-Polymer Alloy is the way IB Roof Systems refers to its PVC product. IB membranes are 100% ‘compatible’ with other PVC products).

IB Solar Wise - building integrated PV systems that seamlessly installs with IB single-ply flat roofing membranes with no roof penetrations. Generate free electricity, and have your Solar PV system pay for itself in under 5 years!


IB SolarWise Video

Until recently, 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 a home or a 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 the 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 not the case. 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, watertight 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 roof-integrated solar system installed vs. a conventional solar system.

Installation of solar roofing


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 a 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 Jack 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 from 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 an 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 too 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 a 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 from the solar panels’ rack mounts and the roof lasts 12 years, after which the repair process described above has to take place, unless of course you are willing to take the 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 РSolarWise PV modules (solar panels) generate free electricity** by converting sunlight 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 your pay-off period! But that is not all Рthere 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 your 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, notorious for constant roof leaks.

4 РIB 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 does IB SolarWise PV work?

IB SolarWise PV produces a DC-current, which goes into an Inverter where it becomes an AC-current. The inverter is connected to you¬†home’s or building’s electric circuit and also to your meter. You use all the 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 sunlight 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 than is consumed. Therefore,¬†all excess kWh sent to the grid in the summer you will use in the winter, when a lot less sunlight is available.

Frequently Asked Questions

This section is designed to cover the topics that you are most interested in, and always ask us about.

  • 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 an 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.
