PVC Membrane
PVC Membrane is a popular type of flat roofing material made from flexible plastic. It's like a thick, durable sheet that gets laid over a roof to keep water out. Roofers choose PVC Membrane because it's long-lasting, resistant to weather damage, and can be heat-welded at the seams to create a completely waterproof barrier. Similar materials include TPO and EPDM roofing. These materials are all part of what's called "single-ply roofing systems," which means they're installed as a single layer rather than multiple layers like traditional roofing.
