When does a California roofer need a C-39 license?

Roofing contractors are licensed by CSLB in the C-39 Roofing classification. A C-39 contractor installs products and repairs surfaces that seal, waterproof and weatherproof structures, using materials such as asphaltum, pitch, tar, felt, metal roofing systems, shakes, shingles, roof tile, slate and other membrane materials.

The contractor license law does not apply to work under $1,000 in total (labor, materials and everything else) that is casual, minor or inconsequential and does not need a building permit. The exemption is lost if the job is split up to get under $1,000, if the person advertises as a contractor, or if they employ anyone to help (B&P 7048). AB 2622, approved in September 2024, raised this limit from $500 to $1,000, and the section was amended again effective January 1, 2026.

Penalties

Contracting without a license is a misdemeanor. A first conviction can bring a fine up to $5,000, up to six months in county jail, or both. A second conviction brings a fine of the greater of $5,000 or 20 percent of the contract price, and at least 90 days in jail in most cases. Charges must be filed within four years (B&P 7028).

After a declared disaster

After a Governor-proclaimed state of emergency or a presidentially declared emergency or major disaster, unlicensed contracting for repairs or improvements to a structure damaged by that disaster can bring a fine up to $10,000, state prison time of 16 months, two years or three years, or both, or a fine up to $1,000 and county jail up to one year (B&P 7028.16). The person who used the unlicensed contractor is treated as a crime victim even if they did not know the contractor was unlicensed. (source: California Legislature)
