Flat Roofing | East Bay Roofers

Flat and low-slope roofing systems require specialized membrane installation to achieve a watertight seal across the entire surface. We install TPO (thermoplastic polyolefin), EPDM (ethylene propylene diene monomer), PVC membrane, modified bitumen, and built-up roof systems — selecting the right membrane for your building's needs, climate, and budget.

5 Key Highlights — Flat Roofing

Flat and low-slope roofing systems require specialized membrane installation to achieve a watertight seal across the entire surface
Installation begins with rigid insulation boards over the roof deck, providing thermal performance and a smooth substrate
The membrane is rolled out and adhered with adhesive, heat-welded at seams (TPO and PVC), or torch-applied (modified bitumen)
Every parapet wall, drain, pipe penetration, and HVAC curb gets custom-fabricated flashing
For built-up roofs, we mop or spread alternating layers of bituminous felt and asphalt to build a multi-ply waterproof system

Signs You Need Flat Roofing

Visible damage or deterioration — any signs of wear, cracking, or aging in your roofing system warrant a professional flat roofing assessment
Recurring problems — if the same issue keeps coming back after temporary fixes, it is time for a proper flat roofing solution
Age of existing system — older systems past their expected service life often cost more to maintain than to address with professional flat roofing
Water intrusion or leaks — any active moisture penetration requires prompt attention to prevent structural damage and mold growth
Failed previous repair — work that was done incorrectly or has deteriorated needs professional flat roofing to fix the root cause
