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.

Roofing demand in San Leandro is driven less by storms than by wildfire exposure, heat aging, and Title 24 cool-roof rules. Class A fire-rated assemblies and cool-roof-compliant materials are the priority in most jurisdictions. Of the 1 companies we track, 1 hold a manufacturer certification for these systems.

1 of the 1 roofers we track in San Leandro hold at least one manufacturer certification (GAF, Owens Corning, CertainTeed, TAMKO, IKO, Malarkey). 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.

We show any recorded violation - citation, severity, and penalty - on each profile. A clean record isn’t a guarantee, but repeated serious violations are a real red flag.
