Ethylene propylene diene monomer (EPDM)

EPDM, which stands for Ethylene Propylene Diene Terpolymer, is a rubber roofing usually installed on residential and commercial roofs. The most common and sought-after single-layer membrane material is EPDM, also known as a rubber roof. This material is one of the first choices for commercial and residential use for roof installation.

Most of the time it is installed like a huge sticker, but it needs to be done slowly and precisely to avoid air bubbles. Else, you will face some difficulties.
