522 Roofing Companies in California: Public Records & Data

In California, roofing contractors must be licensed through the Contractors State License Board (CSLB). Roofing work falls under the C-39 Roofing classification, which requires applicants to demonstrate at least four years of journeyman-level experience in the trade within the past ten years. To obtain a license, applicants must pass two written examinations: a trade-specific law and business exam and a C-39 roofing trade exam. The application fee is currently $450, and applicants must also provide a contractor's bond of $25,000, which is required by state law to protect consumers from incomplete or defective work.

Once licensed, contractors must maintain active workers' compensation insurance if they have employees, and they must renew their license every two years. The renewal fee is approximately $450. Contractors operating as a sole owner with no employees may qualify for a workers' compensation exemption. The CSLB also requires licensees to keep their bond and any required insurance current throughout the life of the license, and failure to do so can result in automatic license suspension. All licensed contractors receive a license number that must be displayed on all contracts, advertisements, and vehicles used for business.

Beyond state licensing, some California cities and counties impose additional local business license requirements and permits for roofing work. For example, jurisdictions such as Los Angeles and San Francisco may require separate business tax registration certificates and building permits for roofing projects above a certain value. Contractors should check with the local building department in each jurisdiction where they plan to work to ensure full compliance with local regulations in addition to the statewide CSLB requirements.
