Roof Membrane

A roof membrane is a continuous waterproof layer used primarily in flat and low-slope roofing systems. It acts as the main barrier against water infiltration and is commonly made from materials such as EPDM, TPO, PVC, or modified bitumen. Roof membranes are designed to withstand ponding water, UV exposure, and temperature fluctuations. In commercial roofing applications, they provide long-term protection and energy efficiency. Proper installation is essential to prevent leaks, as seams and joints are critical weak points. Roof membranes are a key component in modern waterproof roofing systems.
