FAQ
Common Questions
Why CSLB Verification Matters for Roofing Projects
California law requires any contractor performing roofing work valued at $500 or more — including labor and materials — to hold an active license issued by the California Contractors State License Board (CSLB). For roofing specifically, that means a C-39 Roofing Contractor license . Hiring an unlicensed roofer isn't just risky — it's a violation of Business and Professions Code Section 7028 , and it leaves you with zero legal protection if the work fails.
A valid C-39 license tells you three critical things: the contractor passed a state trade exam, maintains an active bond of at least $25,000, and carries workers' compensation insurance for their crew. If someone working on your roof gets injured and your contractor isn't properly licensed and insured, you — the homeowner — can be held financially liable. All roofing installations must also comply with California Building Code (CBC) Section 1507 , which governs roof covering requirements, material standards, and installation methods for residential and commercial structures.
Every contractor in the NexaBuilder network has been checked against the CSLB database before they ever receive a homeowner referral. We verify license status, confirm the license classification matches your project type, and check for any disciplinary actions or complaints on file. For example, a verified contractor in our network will carry a credential formatted as CSLB License #1234567 — always confirm this number matches an active C-39 classification on the CSLB database before signing any contract.
