Flat roofs don't drain like sloped roofs. Water sits instead of running off. That fundamental difference means flat roofing requires specialized materials, installation methods, and drainage solutions. Best Roofers Near Me | Phoenix installs and repairs TPO, PVC, EPDM, and modified bitumen flat roofing systems throughout Phoenix.

Modified bitumen is our recommendation for residential flat roofs and high-traffic commercial applications. Two-ply torch-applied SBS system with a granulated cap sheet handles foot traffic, thermal cycling, and AZ UV exposure. It's the toughest flat roof membrane for everyday abuse.

Flat roof leaks usually happen at penetrations, seams, or flashing details, not in the middle of the membrane. We locate the source with electronic leak detection or flood testing, repair it properly, and address the root cause. If the membrane is shot, we recommend replacement, not a band-aid.

Flat Roofing FAQ

TPO is more energy-efficient (reflective white) and has stronger seam welds. EPDM is proven over 50+ years and typically costs less. Both are solid choices. We recommend TPO for energy savings and EPDM for budget-conscious projects.

It depends on the application. TPO is great for energy efficiency. PVC resists grease and chemicals. EPDM is proven and affordable. Modified bitumen handles foot traffic well. We recommend based on your building's specific needs and budget.

A roof coating is a liquid-applied membrane, usually silicone or acrylic. That extends the life of an existing flat roof by 10-15 years. It works when the existing membrane and insulation are in reasonable shape. We core sample and moisture test to determine if your roof qualifies.

Flat roofing in Phoenix runs $5-$12 per square foot depending on the membrane type, insulation requirements, and drainage design. TPO and EPDM are mid-range, PVC is higher, and coatings are the most affordable for qualifying roofs.

Yes. Semi-annual inspections checking seams, flashings, drains, and membrane condition prevent small issues from becoming expensive repairs. Drain clearing is especially important. Clogged drains cause ponding that damages the membrane.
