Flat Roofing

Commercial Roofing — Walnut Creek, CA

Flat and low-slope roofing requires specialized expertise. Walnut Creek Roofers designs and installs EPDM, TPO, modified bitumen, and built-up roofing systems for commercial buildings throughout Walnut Creek, CA.

The best flat roofing system for your Walnut Creek building depends on your drainage, insulation requirements, foot traffic, and budget. Our commercial roofing team evaluates your specific conditions and recommends the system that balances performance and cost over the long term.

EPDM (synthetic rubber) offers the best value for low-budget applications and has decades of proven performance. TPO single-ply membrane provides the best energy efficiency and is our top recommendation for most commercial applications. For buildings with rooftop equipment or foot traffic, we recommend modified bitumen or built-up systems with walkpads.
