TPO is a single-ply thermoplastic membrane whose seams are heat-welded into one continuous, watertight surface. Its bright, reflective finish lowers cooling costs in warm climates, and it combines strong UV resistance with flexibility and a competitive price — one of the most popular choices for commercial and industrial flat roofs.
FAQ — TPO flat roofing
What makes TPO different?
Heat-welded thermoplastic seams and a reflective surface often used for cool-roof performance on commercial flats.
Is TPO good for warehouses?
Frequently yes — large areas benefit from welded seams and competitive installed cost when the design fits.
How are TPO seams waterproofed?
Seams are heat-welded into a continuous membrane — workmanship and detailing at penetrations are critical.
TPO vs EPDM — which should I pick?
Depends on climate goals, substrate and maintenance. We compare both on-site rather than pushing one system.

Description
Thermoplastic polyolefin (TPO) is a highly preferred roofing system in the commercial sector and is also often used for residential roofs. It is widely recognized for its exceptional resistance to ultraviolet (UV) rays, making it a durable choice. Its versatility allows it to be used in both new construction and roof renovation projects.
One of the key advantages of TPO is that, on a roof in good condition, it can be mechanically fixed with screws and plates or glued directly to the surface. This eliminates the need for complete stripping, making TPO an economical choice for many projects.
In addition, TPO is favored for its recyclability and color variety. Lighter colors such as white and light gray are particularly beneficial because they reflect more sunlight, reducing heat transfer into the building. This not only increases the building's energy efficiency, but also supports environmental sustainability goals, resulting in long-term cost savings.
