EPDM (Ethylene Propylene Diene Monomer) is a durable and reliable material that works well in extreme conditions, particularly the conditions that are found on flat roofs.
The great thing about EPDM is the fact that it is an extremely ECO-friendly material that can be applied with very little energy. Both the Government and the International Kyoto Ecology Agreement recommend EPDM rubber as the best value, sustainable eco-sound roofing. Greenpeace, the international environmental agency, put EPDM membranes at the top of their rankings of low-impact membranes in their "Building For The Future" report. This ranking was based on EPDM’s environmental sustainability due to its extended lifespan and re-usability.
EPDM membrane roofing is also ideal for green roofs where sedum plants form a top layer as EPDM will provide a waterproof rubber coating that is necessary for green roofs.
