There has been a lot of discussion on our rubber roofing page (created a while ago), with many roofing contractors defending the EPDM rubber roof as a “good and proven” system, that is widely installed. While I agree that it is widely installed, I contest the notion that it is good and proven, for many reasons, which I will outline below, with examples as proof. But first, I will outline the basic premise on which I will base my statements.
Basic Premise of this “Horrible Rubber Roofing” article
Rubber roof (EPDM) is widely installed because of its relatively low cost. It is NOT as good as many roofing contractors say it is, and the reason why I call it “horrible” is a complex, but there are two major parts to it: Continue reading →
In December 2012, we installed an IB PVC roof in a duplex-condo in Brooklyn, NY. This new roof replaced an old leaking tar roof that was over 20 years old. The roof was leaking in multiple places, around skylights, and along separation wall flashing.

The new membrane installed was a 50-mil white IB PVC roof, with hot-air welded seam overlaps. The roof was mechanically fastened to the deck, using corrosion resistant screws and barbed plates, to provide a 130 MPH wind resistance.
We flashed two existing dome skylights, one roof hatch, and about 50 lineal feet of roof to wall / separation wall, using aluminum termination bar.
Why IB PVC Roof?
Although there are cheaper alternatives for a flat roof replacement, IB Roof is the best Flat Roofing material for residential and commercial application. IB Roof is a reinforced PVC membrane that features Fusion Hot Air welded seams and flashing. Hot air welding makes ALL the difference, when it comes to sealing the seams and overlaps.
Unlike traditional roofing materials that rely on sealants to join overlaps, hot air welding creates a permanent physical bond between two sheets of membrane. This means that two pieces essentially become ONE piece. The seam will never come apart (when done correctly) and is actually stronger than the material itself!
By comparison, other flat roof materials that are sealed with bonding adhesive will be leaking in just a few short years, when adhesive (glue) begins to fail. This will result in expensive roof and interior repairs, headaches for you – the owner, and potential frame/substrate rotting and mold.

In the early fall of 2012, Cool Flat Roof installed an IB PVC roof with tapered insulation and new gutters on a beautiful contemporary new construction house in Weston, Massachusetts.
Initially, the homeowner contacted us, looking for a “rubber roof”, and I immediately explained that we do not install EPDM rubber, because it does not meet our quality standards (more on why we don’t install rubber roofs here and here).
Instead, I suggested our IB PVC flat roofing systems, with Lifetime Warranty, and hot air welded seams, that will never come apart. After receiving аn estimate from us and several other roofing companies, they chose us to install a more expensive, but a much more durable and long lasting IB roof.
Total roof size was approximately 3500 sq. ft. installed on two levels – the main upper roof, and a lower garage roof, connected to the back porch. The roof was to be installed over unprotected roofing substrate (plywood), and we had to start the roof and get it watertight fast, in lieu of prolonged, massive rains. We installed all roofing materials and welded all seams and flashing in 2 days, to protect the substrate and inside of the house from being damaged by rain water. The roof was priced based on our Flat Roofing Calculator, so there were no last minute surprises about the cost of this project.

One of the most important ways to protect your commercial property is to have a durable, long lasting roof. For flat roofs, the most trusted and time tested roofing material is a PVC roofing membrane. Known for their durability, commercial PVC roofs have been installed on restaurants, shopping centers, manufacturing plans, industrial facilities, etc. covering millions of square feet worldwide. Learn in detail about all the advantages of PVC roofing that make it an ideal roofing choice for your business.
IB PVC ROOF IS DURABLE
A PVC roofing membrane is specifically formulated to remain durable in a wide variety of conditions. To ensure optimal strength and durability, it is best to install a membrane of at least 60 mil. A PVC roof offers the following protection:
– Resistance to impact and abrasion (possible with with photovoltaic panels on the roof).
– Withstands inclement weather (rain, snow, wind, sun, hot and cold temperatures)
– High Resistance to punctures, tears, and impact.
– Tough against contamination and rooftop soiling
– Class A Fire Resistance (the membrane will resist flames rather than fuel them)
– Withstands ponding water( the membrane is impervious to moisture and leaks)
– High resistance to oil, grease,chemicals, and diluted acidic effluents
How would you like to have an extra outdoor private space in your home to relax or entertain guests? A roof deck is an ideal option that will not only be enjoyable for years to come, but will also increase the value of your home.
Whether you are thinking of constructing a new roof deck or would like to improve the one you already have, it is essential for your deck to be leak free.
There are a number of issues that cause leaks in roof decks and a number of best practices that you can follow to keep leaks at bay.
Common leak causes and other issues with roof decks
One of the common reasons why roof decks leak is ponding water that forms on the roof. Ponding water occurs for a number of reasons such as inadequate roof drainage or roofing material failures. Most flat roofing materials, such as EPDM rubber, rely on adhesives to seal the seams and flashing around penetrations. Over time these adhesives break down and cause leaks. Ponding water further exacerbates this problem by increasing the rate at which seam adhesive fails. Continue reading →
