EPDM (ethylene propylene diene terpolymer) is a highly durable material used in low-slope roofing applications. Its two primary components, ethylene and propylene, are derived from oil and natural gas. Sold in black and white, the rubber material is sold in rolls in a range of widths, allowing great customization of your EPDM single-ply membrane roofing project.
Advantages of EPDM Roofs
One of the most cost-effective roof material options (about $1.50 per square foot)
- Lightweight material allows for easy installation
- When maintained properly, can last for up to 50 years
- Easy to repair if leaks or other damage occurs
Installation of EPDM Roofs
EPDM is one of the easiest and most flexible roofing materials to install. EPDM can be fully adhered to the top of your structure, sitting directly on top of the roofing insulation. EPDM can also be ballasted with wood, metal, or stone reinforcements for greater durability and strength. Seams between sections of EPDM material are closed with liquid adhesive chemicals or special roofing tape to create a weatherproof seal.
Disadvantages of EPDM Roofs
- Installation becomes more challenging on roofs with protrusions (chimneys, lanterns, vents, etc.)
- Because of the relatively thin material, EPDM can be punctured by falling tree branches or foot traffic
- Since EPDM has only been common for about 40 years, finding a qualified technician can be challenging
