EPDM is a service offered by Arcamm Roofing, Insulation & Eavestrough within Toronto and surrounding areas.
EPDM, or ethylene propylene diene terpolymer, is a very durable synthetic rubber roof membrane used widely in low slope structures in the U.S. and around the world. Its main ingredients, propylene and ethylene, are derived from natural gas and oil. EPDM is available within both white and black, and is sold at a wide variety of widths, which range from 7.5’ – 50’, and in a couple of thicknesses, 45 and 60 mils. It may be either installed fully adhered, ballasted, or mechanically attached, with the roofing system seams sealed with liquid adhesives or uniquely formulated tape.
What EPDM looks like
Black EPDM will have a smooth surface like natural gray slate and doesn’t have surface granules which eventually can be lost on additional materials. Also, white EPDM has a smooth surface, yet is white. It’ll combine the high performance standards of EPDM of a traditional nature with an extremely reflective, eco-friendly surface made to slash energy expenses. As appropriately used, typically in hot climates, white EPDM may decrease AC costs without having to sacrifice durability of a roofing system.
What’s the expected longevity of an EPDM membrane?
With a multitude of EPDM installations that exceed four decades of exposure in the industry under a variety of climatic conditions, none of the tested material has displayed alarming indications of degradation. Although it’d be hard to predict, research has shown aged EPDM membrane as possessing a possible life expectancy of five decades.
