Roofing Contractor License in California: What Homeowners Must Know
California has some of the most detailed contractor licensing requirements in the country — but they only protect you if you verify them before signing. Here is what the law requires, what it means in practice, and exactly how to check any roofer before they touch your home.
What License Does a Roofer Need in California?
California requires a C-39 Roofing Contractor license for any roofing work exceeding $500 in combined labor and materials. The C-39 is issued by the California Contractors State License Board (CSLB) and requires:
- Passing a C-39 trade examination
- Passing a California law and business examination
- Proof of active workers' compensation insurance
- A surety bond of at least $25,000
- Four years of verifiable journeyman-level experience
The CSLB maintains public records on every licensed contractor. Rescue Roofer holds C-39 license St. Lic #1137524, issued 1993 and continuously active.
How to Verify a License
Go to cslb.ca.gov and use the "Check a License" tool. You can search by business name or license number. The result shows:
- Current license status (Active, Suspended, Expired)
- License classifications held
- Bond and insurance status
- Any disciplinary actions, citations, or complaints
Always verify before signing — never accept a license number verbally without checking it yourself.
What Can Go Wrong With an Unlicensed Roofer
You may be liable for injuries
If an unlicensed contractor is injured on your property and does not carry workers' compensation insurance — which licensed contractors are required to — you may be held liable for their medical costs as the property owner.
Work without permits cannot be legalized retroactively
Roof replacements require permits in every Orange County city. Work done without a permit must be disclosed when you sell. If the unpermitted work is discovered during escrow, you may be required to have it redone — at your cost — to obtain sign-off.
No legal recourse if work fails
California law limits your recovery from unlicensed contractors. If the roof leaks after they leave and you cannot reach them — a common pattern with storm-chaser crews — you have limited options. Licensed contractors are bonded, insured, and subject to CSLB discipline.
The Right Questions to Ask
Before any contractor starts work, ask for the C-39 license number, verify it at cslb.ca.gov, and request a Certificate of Insurance showing both general liability and workers' compensation coverage. Then read our guide on all 7 questions to ask before you sign.
