A brief history of EPDM roofing

Carlisle was the first roofing company to use the DuPont technology to make EPDM rubber roofing for the roofing market. They had this market to themselves until early 1980s when Colonial Rubber Works started making their own version of EPDM roofing. In the late 1980s,  Firestone Building Products started making their own version EPDM roofing. Even though there are many brands of rubber roofing such as Johns Manville, Celotex, Mule-Hide, Centimark and others, all of the EPDM roofing was manufactured by one of the three previously mentioned companies. Then in 1993 Firestone Building Products bought Colonial Rubber Works roofing division. This left only two manufactures of EPDM rubber roofing in the United States.  Presently these are still the only two manufactures of EPDM in the U.S.. Both companies offer a quality product that will withstand the harsh conditions often found on a roof. The only noticeable difference between the two roofing membranes is that Carlisle's product has more visible dust on its surface. So it requires more cleaning. Both manufactures offer a twenty year warranty on their product. EPDM roofing is well known for it's great U.V. resistance. U.V. rays from sunlight is one of the primary factor in making other roofing products crack and fail. EPDM roofing is also a very user friendly product and it can be installed by a homeowner with just a few basic instructions.
