EPDM (Ethylene Propylene Diene Monomer) rubber is one of the leading types of single-ply roofing membrane and I thought for this reason I would talk a bit about it in this week’s blog. The usual use for EPDM rubber is on flat or low-slope roofs.
Most rubber roofs are black, but it does come in white to reflect the sun. White EPDM rubber membrane roofing costs a little more than black. This roof system can be mechanically attached or fully adhered and comes in reinforced and non-reinforced. There is also a less common ballasted roof system. Reinforced is used for mechanically attached, and non-reinforced is used for fully-adhered systems. Ask your roofer which one makes the most sense for your roof.
The EPDM rubber sheets come in rolls from five feet up to 50 feet wide. The sheets wider than 10 feet are for fully-adhering only, in most cases. Because covering a roof requires more than one sheet, there are seams in a rubber roof. These seams are primed and an inseam tape is installed to make them water tight. A roofer must be skilled and take extra care in properly seaming the sheets and installing rubber roof flashings.
Rubber roofs should last from 15 to 30 years. Your roofer should provide a workmanship warranty too.
