GenTite Residential Roofing Systems


With the revolution of the tire industry in the early 1970s to radial tires, came the revolution of the low-slope roofing industry in the 1980s. With companies like Goodyear, Firestone and Carlisle branching into the building products market to keep their machines running came General Tire’s GenFlex Roofing Systems.

Radial tires have a longer lifespan and it was because of this that tire manufacturers were trying to find new things to produce with their equipment with all the new downtime on the machines. Eventually someone figured out that if the rubber was made into sheets and put on a roof, it made for an outstanding roofing system that now accounts for about 51 percent of commercial roofs installed in North America.

Building on that trend, GenFlex Roofing Systems has introduced its GenTite Residential Roofing Systems. This full line of commercial-grade, low-slope roofing products for the residential market provides a high-performance roof that is easy to install.

“If you go to any older home with a patio, porch, shed dormer or carport attached to the home, that is typically going to be a low slope condition,” says Dan Thomas, business development manager of GenFlex Roofing Systems.

“Low slope by definition is a difficult roof to make water tight. Shingles are not water-proof. Shingles are water shedding like fish scales and are applied in a way to shed the water off the roof. If you’re in a low-slope condition you need a water-tight system there or water will penetrate the roof.”

GenFlex Roofing Systems makes both EPDM (Ethylene Propylene Diene Monomer) and TPO (a high quality thermoplastic polyolefin) membranes. GenFlex EPDM is a high-quality rubber membrane that is resistant to tears, impacts, punctures and normal foot traffic. Normal structural movement has limited effect on its integrity. This membrane provides excellent resistance to ozone and ultraviolet light exposure.

Like EPDM, GenTite TPO roofing systems are designed for durability and to withstand extreme environmental exposure. The bonus is the reflectivity of the white membrane is proved to keep solar heat out of buildings, increasing energy savings. In some geographic regions, GenTite TPO “cool roof” systems stay 50 to 60 degrees F. cooler at peak times than traditional roofing membranes. GenFlex white TPO products meet the stringent criteria of the LEED program and California Title 24 Standards.

“The only limitation that a remodeler should be aware of is that you can’t go directly over an asphalt-based roof,” explains Thomas.
