Commercial Roofing Systems Anderson Installs

Anderson Roofing installs multiple low-slope systems suited to San Francisco's commercial building stock. Flat and low-slope rooftops, common on warehouses along Cesar Chavez Street, mixed-use buildings in the Mission District, and office blocks in SoMa, face persistent fog-cycle moisture, salt-laden Bay air, and steady coastal winds. Choosing the right system from the start matters for any commercial roof installation in San Francisco, CA.


Built-Up Roofing (BUR): Anderson installs 4- and 5-ply built-up roofs using hot asphalt. A gravel surface finish can achieve a Class A fire rating required under the San Francisco Building Code. BUR systems may deliver 20 to 25 years of service life.


Modified Bitumen: Anderson applies modified bitumen using hot asphalt rather than torch application, which helps avoid the need for a separate San Francisco Fire Department operational permit.


Single-Ply Membrane: Reflective single-ply options can satisfy California Title 24 cool roof requirements for commercial low-slope roofs in San Francisco (Climate Zone 3). Compliance requires a product rated by the Cool Roof Rating Council (CRRC) with the CRRC product ID noted on the SFDBI permit application.


Metal Roofing and Sheet Metal: Corrosion-resistant metal systems suit the Bay Area's coastal environment and are a core Anderson specialty. Custom sheet metal work, flashing, gutters, and downspouts can be integrated as part of a full installation.

What Does the SFDBI Permit Process Look Like for a Commercial Roof?

San Francisco requires a permit from the Department of Building Inspection (SFDBI) before commercial roof installation begins. The steps typically follow this path:


1. Finalize project scope and select materials meeting the San Francisco Building Code and Title 24 energy standards.

2. Submit a permit application to SFDBI, including occupancy classification, construction type, roof slope, proposed materials, project valuation, and the CRRC product ID if required.

3. Obtain any additional permits, such as an SFFD operational permit if a torch-applied system is involved.

4. Begin installation only after all permits are issued.

5. Schedule and pass the final SFDBI inspection to close the permit and confirm code compliance.


Anderson has operated from the same San Francisco location since 1965 and carries the C-39 roofing contractor license required to apply for SFDBI permits directly, helping owners avoid costly delays from non-compliant materials or missing documentation.
