TPO Roofing in Los Angeles
TPO is one of the most common flat-roof systems on Los Angeles commercial buildings: a reflective, heat-welded single-ply membrane that handles strong sun well. We install, repair and replace TPO roofs on warehouses, retail and multifamily buildings across Los Angeles County.

- A single-ply thermoplastic membrane, usually white or light-colored.
- Seams are heat-welded, creating a continuous waterproof surface.
- Reflective surfaces reduce heat gain and can help meet cool-roof requirements.
- Installed fully adhered, mechanically attached or, less often, ballasted.
- Membrane thickness and manufacturer warranty options vary by project.
Strengths and trade-offs
Reflective
White TPO reflects sunlight, which helps keep buildings cooler and can support cool-roof compliance. See LA cool roof requirements.
Welded seams
Heat-welded seams are typically stronger than taped or glued seams.
Cost-effective
TPO is often among the more economical single-ply options for large roofs.
Workmanship-sensitive
Weld quality and detailing at edges and penetrations decide how well it performs, so installation matters as much as the membrane.
Choosing between them
| TPO | PVC | |
|---|---|---|
| Seams | Heat-welded | Heat-welded |
| Chemical and grease resistance | Good | Strong; often chosen for restaurants |
| Relative cost | Typically lower | Typically higher |
| Typical use | Warehouses, offices, multifamily | Restaurants, food processing, chemical exposure |
See PVC roofing for restaurant and grease-exposure roofs.
Install, repair, replace
We install new TPO roofs as part of commercial roof installation and replacement, and repair existing TPO through flat roof repair. If your TPO roof is aging but the insulation is dry, a coating may extend its life. Compare every system on our roofing systems page.

Frequently asked questions
How long does a TPO roof last?
It depends on membrane thickness, installation quality, sun exposure and maintenance. Ask for the manufacturer's warranty terms for the specific product.
Is TPO good for Los Angeles?
Yes, for many buildings. Its reflective surface handles strong sun well and can help meet cool-roof requirements.
Can TPO be repaired?
Yes. Punctures and open seams are typically repaired with hot-air welded TPO patches.
What's the difference between TPO and PVC?
Both are heat-welded single-ply membranes. PVC resists grease and chemicals better and usually costs more.
