history of epdm roofing

Carlisle was the first roofing company to use the dupont technology to make epdm roofing for the roofing market. They had this market to themselves untill early 1980s when colonial rubber works started making their own epdm roofing. Then firestone building products started making their own epdm roofing in the late 1980s. Even though there are many brands of roofing such as johns manville, celotex, mule-hide, centimark and others. All of the epdm roofing was manufactured by one of these three companies. Then in 1993 firestone building products bought colonial rubber works roofing division. So now there are only two manufactures of epdm roofing in the united states today. Both companies offer a quailty product that will withstand the harsh conditions often found on a roof. The only noticable difference between the two roofing membranes is that carlisle's has more visible dust on it. So it requires more cleaning. Both manufactures offer twenty year warrantys on their product. Epdm roofing is well known for it's great u.v. resistance. U.V. sunlight is one of the primiary factors in making other roofing products crack and fail. Epdm roofing is also a very user friendly product and can be installed by an individual homeowner with good instructions.
