How to check a license in California
- Search using the license number, the business name, or the name of whoever qualifies the license.[1]
- Confirm the classification reads C-39, the roofing classification, rather than relying on a general "B" license for a single-trade roof job.[2]
- Check that workers' compensation is shown on file; C-39 roofers must carry it whether or not they have employees.[2]
- Review the license's status and any disciplinary history displayed on the same result page.[1]

Warning signs
- A license status that reads inactive, revoked, or suspended, or a business name that doesn't match your bid.[1]
- No pocket license or photo ID offered when someone arrives to give you a bid in person.[3]
- A deposit bigger than the state's own cap, the smaller of a tenth of the job's price or $1,000, without a bond on record to explain the extra.[4]
- Pressure to waive or rush past your three-day right to cancel after signing.[4]
Rules that protect you
- California requires a $25,000 bond for a C-39 license, on top of mandatory workers' compensation coverage for every C-39 roofer.[2]
- Any roofing job with combined labor and materials of $500 or more requires a C-39-licensed contractor by law.[2]
- A written contract is required for home improvement work over $500, with a right to cancel within three days of signing.[4]
