- Single-ply membranes (TPO, PVC, EPDM) cover most flat commercial roofs in Los Angeles.
- PVC is the usual choice where grease or chemicals reach the roof.
- Modified bitumen and built-up roofs handle foot traffic well and are common on older buildings.
- Metal suits buildings with enough slope and a long ownership horizon.
- Coatings can restore many existing roofs without a tear-off.
Commercial roofing systems
TPO roofing
Heat-welded, reflective single-ply membrane and one of the most common flat-roof choices in Los Angeles.
PVC roofing
Heat-welded single-ply with strong resistance to grease and chemicals, suited to restaurants and food processing.
EPDM roofing
Durable synthetic rubber membrane with a long track record on low-slope buildings.
Modified bitumen
Multi-ply asphalt-based system that handles foot traffic well, common on older commercial buildings.
Built-up roofing
Layered asphalt and gravel systems still found across Los Angeles industrial buildings.
Spray foam (SPF)
Seamless foam roofing that insulates and waterproofs, protected by a coating that needs periodic renewal.
Metal roofing
Standing seam and panel roofs for industrial and commercial buildings.
Roof coatings
Silicone and acrylic restoration over existing roofs that are still sound.
How the main systems compare
| System | Best for | Watch for |
|---|---|---|
| TPO | Warehouses, offices, multifamily; reflective roofs | Weld quality and edge details |
| PVC | Restaurants, kitchens, chemical exposure | Higher cost than TPO |
| EPDM | Low-slope roofs where heat reflection matters less | Seam tape aging; dark surface unless coated |
| Modified bitumen | Roofs with regular foot traffic | Heavier; seams and laps age in strong sun |
| Metal | Sloped roofs, long ownership | Fastener maintenance on exposed fastener panels |
Matching the system to the building
We look at roof slope, drainage, what’s venting onto the roof, foot traffic from equipment service, cool-roof requirements and how long you plan to own the building. Then we recommend a system and explain why, in writing. See LA cool roof requirements for the energy-code side.
New systems go on through commercial roof installation and replacement; existing ones are handled through repair, flat roof repair and maintenance. Not sure what’s on your roof now? A roof inspection identifies the system and its condition. We install and repair every system on this page across Los Angeles County; see our service areas, browse our commercial roofing guides, or read about our company.

Frequently asked questions
What is the most common commercial roof in Los Angeles?
Single-ply membranes like TPO are among the most common on flat commercial roofs, along with older built-up and modified bitumen roofs.
Which roofing system is best for a restaurant?
PVC is usually recommended where kitchen exhaust puts grease on the roof, because it resists grease better than many membranes.
Can an existing roof be coated instead of replaced?
Often, if it's structurally sound and the insulation is dry. An inspection determines it.
How do I know what roofing system my building has?
An inspection identifies the system, its age and condition, with a photo report.
