Short for thermoplastic polyolefin, TPO is a single-ply roofing membrane that offers excellent performance at a cost-effective price. Heat-welded seams provide superior strength. TPO's longterm heat, UV, and natural fungal resistance, plus flexibility without need for plasticizers also make TPO a reliable low-slope roofing system.
In the 20+ years that TPO has been in the field, it’s become one the most popular products used for low-slope roofing. Over 1 billion square feet are installed annually, making up over 50% of single-ply roofs being installed today.
