EPDM, or Ethylene Propylene Diene Monomer, is a rubber membrane material used for flat roof applications, including porches and low pitch dormers. As recent Maine winters have demonstrated, snow and ice buildup can wreak havoc on low pitch roofs with asphalt shingles, even when ice and water shield underlayment products are installed. Low roof pitch keeps snow and ice trapped, causing ice dams. Horch Roofing recommends EPDM rubber application below a 3/12 pitch. By installing EPDM rubber roofing you won’t have to worry about leaks or damages to your low pitch roof again.

EPDM rubber roofing is a single-ply membrane that lays flat on the roof’s surface. Rubber-based roofing prevents water from seeping through the surface. The EPDM rubber sheets come in rolls from five feet up to 50 feet wide. Because covering a roof requires multiple sheets, there are seams in an EPDM rubber roof. These seams are primed and an inseam tape is installed to make them watertight.

An EPDM roof can last from 15, all the way up to 30 years. Part of this longevity is due to the fact that rubber roofing is strong and flexible and can expand or shrink with the roof as the outdoor temperature changes, unlike shingles, which can split, crack or loosen as a roof expands.
