How to Verify a Roofing Contractor (C39) in California

California requires all contractors performing roofing work valued at $500+ to hold a valid CSLB C39 license. Of the 5,678 licensed roofing contractors in the state, 95% currently hold active licenses and 9.8% have at least one federal compliance record.

Manual vetting takes 45+ minutes per contractor and routinely misses violations in databases most people don't know to check. SiteVetter runs CSLB status, SAM.gov debarment, DOL wage violations, OSHA safety citations, and EPA environmental records in seconds—creating a timestamped compliance artifact.
