EPDM

In Plain English

A durable rubber roofing membrane used on flat or low-slope roofs — the black rubber roof common on commercial buildings.

Definition

Ethylene propylene diene terpolymer — a durable synthetic rubber membrane used as a single-ply roofing material for low-slope applications. EPDM is available in black or white, in thicknesses from 45 to 90 mils, and can be installed using ballasted, mechanically attached, or fully adhered methods. It is valued for its long service life, flexibility in cold temperatures, and resistance to UV radiation.

Example

The 60-mil fully-adhered EPDM system was specified for the school addition to match the existing roofing material and minimize maintenance.
