EPDM Membrane Roof Components
EPDM (ethylene propylene diene monomer) is a synthetic rubber membrane with elastic properties
commonly used to cover low-slope roofs on both residential homes and commercial structures. Its
manufacturing includes the use of cross-linked polymers (custom-designed molecules that bond at
the atomic level) to greatly increase elasticity, strength, and durability. EPDM is a single-ply roofing
system, as opposed to a built-up membrane consisting of multiple layers bonded together.
