What Is TPO Roofing?

TPO (Thermoplastic Polyolefin) is one of the most advanced and reliable flat roofing materials on the market today. It’s a single-ply membrane that offers superior strength, flexibility, and energy efficiency, making it ideal for commercial buildings and other low-slope structures where proper drainage is key.

A TPO roof is heat-welded to create a watertight seal that resists leaks, standing water, and UV damage — ensuring your business stays protected year-round.
