EPDM = ethylene propylene diene monomer. An elastomeric polymer, EPDM is classified as a flexible membrane roofing product. It is one of the key products that caused a revolution in commercial and residential roofing industry materials when it was introduced over the forty years ago.
EPDM is Classified as a "Thermoset”
Because it is typically cured, or vulcanized. This means that the polymer's molecular structure is "set" as a result of heating during the manufacturing process. Uncured EPDM membranes are sometimes used for flashings; but this material is not as effective as it will will eventually cure as it naturally ages under the exposure to UV light and heat.
Cooler, Cleaner & Easier to Install
Early in the flexible membrane market explosion, owners and contractors both recognized EPDM roofing as a much cooler, cleaner and easier product to install than the built-up roofs (hot tar or asphalt) to which they were accustomed. With minimal financial investment, they were able to obtain all the tools and equipment needed to properly install an EPDM roof. Another great benefit of the EPDM roof system is that they are low maintenance, with easy repair options and a low annualized cost. The application does require skilled preparation and application in order for the system to be solid. As demand for flexible membrane systems grew quickly, many contractors assembled crews that specialized in the installation of EPDM membranes to take advantage of the it’s surging popularity.
Two EPDM Application Systems
EPDM membranes may be installed with two types of system applications. The most common and popular installation of EPDM mechanically attaches the membrane using screws and attachment strips. They may also be fully adhered to rigid insulation board or an appropriate structural deck with water or solvent-based adhesives. Both systems eliminates the weight of other recover systems. The mechanically fastened system is widely preferred because it is lightweight and easy to install. Both systems are very attractive, smooth and clean in their final appearance.
