TPO (Thermoplastic Olefin) roofing material is a single-ply roofing membrane made from a blend of polypropylene and ethylene-propylene rubber. It is commonly used in commercial and industrial roofing applications due to its durability, energy efficiency, and low maintenance requirements. 

TPO roofing material is available in a variety of colors and thicknesses, and can be installed using a variety of methods including mechanically fastened, fully adhered, or ballasted.

TPO roofing material is known for its resistance to UV radiation, ozone, and chemical exposure, as well as its ability to withstand extreme temperatures and weather conditions.
