EPDM (short for ethylene propylene diene terpolymer) is a synthetic rubber, single ply roofing membrane used for covering low-slope roofs. It is a thermoset material, which means once it cures after installation it cannot be reheated and softened to accommodate for shrinkage.
EPDM roofing membrane is a popular choice for both new construction and re-roofing, with an estimated 20 billion square feet of it covering the roofs of commercial buildings throughout the US. Installation is much easier than built-up roofing systems, and there are no fumes or odors.
How long does an EPDM roof last?
The service life of a properly installed EPDM roof varies depending on environmental conditions, drainage, foot traffic and, of course, the quality of installation. On average, the EDPM roofs we install in southern Wisconsin have a service life of 25 years.
Characteristics of EPDM Roofing:
- Lower cost than any other roofing system
- Ease of installation, no fumes or odors
- Weighs less than other single ply membranes
- Available in rolls as large as 50’ x 200’ for fewer seams
- Requires regular maintenance and will need to be re-seamed after 5 to 7 years
- The black color absorbs UV light, which shrinks the membrane and makes it brittle—decreasing service life
- Protective walk paths are needed to protect against punctures caused by stepping on any sharp object
- Not eco-friendly due to oil-based byproducts used in manufacturing it
