EPDM’s application methods (ballasted, fully adhered and mechanically attached) allow the membrane to be installed on slopes with positive drainage up to and including vertical applications for fully adhered systems. Good roofing practice always includes provisions for proper drainage for any type of roof system and in most cases, is dictated by local building codes. Because EPDM remains stable over a wide range of temperatures, it allows for year-round installation in all climates.
Many roofing contractors have crews with extensive experience installing EPDM. In an effort to ease installation, EPDM manufacturers continue to implement ergonomic solutions, such as the creation of adhesive application equipment.
