TPO roofing for low-slope commercial buildings.
Overview
TPO (thermoplastic polyolefin) is a single-ply membrane widely used on low-slope commercial roofs. Seams are typically heat-welded, forming a continuous waterproof surface.
It is often chosen for its reflective surface and cost-competitive installation, but performance depends heavily on installation quality, roof design and maintenance. We help you evaluate whether it fits your building.
Reflective surface
Light-colored membranes can reduce heat absorption on the roof.
Welded seams
Heat-welded seams create a continuous membrane when properly installed.
Broad use
A common choice for flat and low-slope commercial roofs.
The problems we solve
Questions to settle before choosing TPO
Is the roof a good candidate?
Slope, drainage, existing layers and structure all influence system choice.
How will seams be handled?
Seam quality is central to membrane performance and worth discussing in detail.
What about penetrations?
Rooftop equipment, curbs and drains need careful detailing.
Who maintains it?
Even durable membranes benefit from periodic inspection.

How long does a TPO roof last?
Service life varies with installation quality, building conditions and maintenance, and it differs between manufacturers. We will not quote a number we cannot support for your specific roof.
TPO, EPDM or PVC: which is better?
There is no universal winner. The best choice depends on the building, budget, exposure and use. See our comparison guide in Resources.
Can TPO be installed over an existing roof?
Sometimes, depending on code, condition and moisture. A roof assessment determines whether that is appropriate.
