TPO (thermoplastic polyolefin), a single-ply roofing material, is often used in commercial construction or on flat roofs. It is a roofing membrane that consists of synthetic components and a fabric-reinforcing scrim. These membranes are used as roofing materials because they provide strength and durability while maintaining flexibility. It is a great choice because it naturally reflects UV radiation while conserving energy and saving you money on utility bills.
