STATE LICENSE
RequiredContractors State License Board (CSLB)
Roofing is licensed as C-39 through the Contractors State License Board. The scope is written around function: installing products and repairing surfaces that seal, waterproof and weatherproof structures, using asphaltum, pitch, tar, felt, glass fabric, urethane foam, metal roofing systems, flax, shakes, shingles, roof tile, slate or any other roofing, waterproofing, weatherproofing or membrane material.
Two things make C-39 the strictest of the twelve trades. First, workers' compensation: since January 1, 2013 a C-39 licensee cannot file a no-employee exemption, and if the certificate is missing the registrar removes the C-39 classification from the license rather than suspending the whole thing. Second, asbestos: any asbestos-related work covering 100 square feet or more requires a C-22 classification or a passed asbestos certification exam — though the statute carves out asbestos bituminous and resinous materials, which is precisely the built-up roofing case.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Roofing licensure is exclusively state — no California city or county issues a roofing trade license. Local building departments issue the reroof permit and must collect the B&P § 7031.5 statement of license number or exemption basis. Many jurisdictions layer on their own roof-covering fire-rating requirements through local amendments to the California Building Standards Code, and cities levy business tax certificates on the contracting business.
The local offices section below names the exact permit desk for every California county on file.
Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of September 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
Roofing carries among the highest workers' compensation classification rates in California, and C-39 licensees cannot avoid it by working solo. Budget the premium, not the $650 in state fees, as the barrier to entry.
Under B&P § 7125(f), a license that is active and includes C-39 loses the C-39 classification when the workers' compensation certificate is missing — the rest of the license survives. If you then work with employees and no coverage, the whole license suspends.
B&P § 7058.5(a) expressly says no asbestos certification exam is required for contractors installing, maintaining or repairing asbestos bituminous or resinous materials — the classic built-up and asphalt roofing case. Other asbestos-containing roofing materials over 100 square feet still trigger the requirement.

Statutory consequences with their citations — not estimates, not “commonly cited” guesses.
A misdemeanor. First conviction up to $5,000 and/or six months in county jail; the second carries a fine of 20% of the contract price, minimum $5,000, plus at least 90 days in jail.
An unlicensed roofer has no right to compensation and the customer may recover every dollar paid, no matter the quality of the work.
Willful or deliberate disregard of the workers' compensation insurance laws is itself cause for disciplinary action against the license, on top of the automatic loss of the C-39 classification.
Inside city limits, the city office listed here issues the permit; the county office serves unincorporated areas. Every office links to its official page.
