Flat roofing is what separates experienced contractors from general roofers. The materials are different, the installation methods are different, and the failure points are different. Duarte Roofing & Maintenance has been installing flat roofs in Duarte for 16 years. We know what works and what doesn't in CA's climate.

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 CA UV exposure. It's the toughest flat roof membrane for everyday abuse.

Our Flat Roofing Process

1

Free Evaluation

We inspect the membrane surface, seam integrity, flashing condition, penetration seals, drain function, and overall drainage pattern. Core samples reveal whether the existing insulation is dry or waterlogged. Full findings provided in a written report.

2

System Recommendation

Your proposal includes membrane type, insulation R-value, drainage design, and warranty coverage. If multiple options make sense, we price all of them so you can compare and choose what fits your budget and goals.

3

Membrane Installation

Flat roof installation requires specialized equipment and training. Our crew uses calibrated hot-air welders for TPO and PVC, torching equipment for modified bitumen, and proper adhesive systems for EPDM. Every seam, flashing, and penetration detail gets individual attention.

4

Warranty & Drainage Test

After installation, we verify drainage by checking water flow to all drain points. No ponding. Every seam tested. Manufacturer warranty registered, 15-20 year coverage depending on system and build-up.

Flat Roofing FAQ

Flat roofing in Duarte 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.

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.
