Waterproof Membrane Roofing is a type of roofing system that is used to create a watertight covering to protect the interior of a building. In many cases, membranes are made from synthetic rubber, thermoplastic (PVC or similar material), or modified bitumen. Low slop roofs may require the use of Single-Ply Membranes to seal and create a watertight system.
