EPDM membranes are synthetic rubber roofing materials made from ethylene, propylene, and diene monomers. They are known for their durability, flexibility, and resistance to weathering, UV radiation, and ozone. Commonly used in flat or low-slope roofs, these membranes can last over 30 years with proper maintenance. Installation of EPDM membranes is relatively straightforward, often involving adhesive or mechanical fastening methods. They are available in various thicknesses and can be black or white, with the latter reflecting sunlight to help reduce energy costs. Their lightweight nature makes them easy to transport and install, contributing to their popularity in commercial roofing applications.
