EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber that has a high degree of ozone and UV resistance, remains flexible in low temperature and does not structurally breakdown in high temperatures. Its resistance to water absorption allows the material to be installed in low slope applications where ponding water cannot be eliminated. Its resistance to high heat makes it the roof material of choice when a high insulation R-value is incorporated into the roof assembly.
EPDM contains no organic matter and will not decay when exposed to moisture from roof leaks or condensation.
EPDM membranes vary in thickness: .045mil, .060mil and .090mil.
In the past, a high reliance on seam adhesives was the weakest component of an EPDM roof system and was responsible for many roof failures. Present day advancements in seam tape technology and the use of semi cured EPDM flashings have fully resolved the past problems associated with seam adhesive failures.
Westcoast is proud to be an approved applicator for both Firestone and Carlyle, two of the leading manufacturers in the North American EPDM roofing market. Our workers undergo mandatory ongoing training and skill development in order to stay current with manufacturers specifications and industry standards.
