California requires roofers to carry a C-39 roofing-contractor license from the Contractors State License Board (CSLB). A company not appearing with a license here isn’t proof it’s unlicensed - some jurisdictions don’t publish - so verify directly, and always confirm liability and workers’ comp insurance before work starts.

9 of the 21 roofers we track in San Francisco hold at least one manufacturer certification (GAF, Owens Corning, CertainTeed, TAMKO, IKO, Malarkey). The most common here is GAF, held by 7 companies - versus 46% certified across California. Certification means the manufacturer vetted the contractor and lets them back your roof with stronger, longer material-and-labor warranties. Not required to install a roof, but a real signal of training and standing.
