A TPO Roof membrane is a thermoplastic polyolefin – a single-ply roofing membrane. TPO Roofing systems are made up of a single layer of synthetics and reinforcing scrim that can be used to cover flat roofs.
TPO Membranes are highly durable. They hold up well to long term exposure for the sun’s ultraviolet light and they are even resistant to bacteria growth and dirt buildup, so it will be easy for you to keep your roof clean.
