From residential reroofing and repairs to large commercial roofing projects, the Golden State offers opportunities for skilled roofing contractors. The state’s varied climate—from intense sun and heat to heavy rain, snow, wind, and wildfire exposures—also makes properly installed and maintained roofing systems an important part of protecting California properties.

If you plan to operate your own roofing business, California requires contractors performing qualifying roofing work to obtain a license through the California Contractors State License Board (CSLB). Roofing contractors are licensed under the C-39 Roofing Contractor classification.

This guide explains California’s roofing contractor licensing requirements, application and examination process, experience requirements, bonding, Workers’ Compensation, and other considerations for operating a roofing business.

Who Needs a Roofing Contractor License in California?

California generally requires a contractor license when a construction project requires a building permit, uses additional workers, or involves $1,000 or more in combined labor, materials, and other project costs.

The exemption for work under $1,000 applies only when the project does not require a building permit, does not use employee labor, and costs less than $1,000. You cannot split a larger project into smaller contracts to avoid the licensing requirement.

Contractors, subcontractors, specialty contractors, and home improvement businesses must generally be appropriately licensed before submitting bids for work that requires a contractor license.

California Roofing Contractor License Requirements

California has a specific license classification for roofing contractors: the C-39 Roofing Contractor License. A C-39 Roofing Contractor installs products and repairs surfaces that seal, waterproof, and weatherproof structures. Roofing contractors may prepare surfaces and work with materials such as:

  • Asphalt and tar
  • Felt and glass fabric
  • Urethane foam
  • Metal roofing systems
  • Shakes and shingles
  • Roof tile
  • Slate
  • Other roofing, waterproofing, weatherproofing, and membrane materials

The C-39 classification applies specifically to roofing work. Contractors who perform work outside the scope of the classification may need additional CSLB classifications.

Eligibility Criteria

To qualify for a California contractor license, you must generally:

  • Be at least 18 years old
  • Have the experience and skills necessary to manage the daily activities of a construction business, including field supervision, or have a qualifying individual who meets these requirements
  • Have at least four years of qualifying experience in the C-39 Roofing classification within the 10 years immediately preceding the application
  • Document and verify the required experience
  • Pass the required CSLB examinations unless you qualify for an examination waiver
  • Complete CSLB's required asbestos open-book examination
  • Obtain the required Contractor Bond
  • Obtain Workers’ Compensation insurance
  • Satisfy all other CSLB requirements for license issuance

Experience and Education Requirements

The qualifying individual must generally have at least four years of qualifying roofing experience within the 10 years immediately preceding the application.

CSLB recognizes experience at the following levels:

  • Journey-level worker
  • Foreman
  • Supervising employee
  • Contractor
  • Other qualifying experience recognized by CSLB

Journey-level experience means you are fully qualified and experienced in the trade and can perform the work without supervision.

California does not require a college degree to obtain a C-39 license. However, qualifying education, technical training, or apprenticeship training may provide credit for up to three years of the four-year experience requirement.

Regardless of education or training credit, applicants must have at least one year of practical experience.

Required Documentation

When applying for a C-39 Roofing Contractor License, applicants generally must provide:

  • A completed Application for Original Contractor License
  • Information identifying the business entity and qualifying individual
  • Certification of the qualifying individual’s work experience
  • Supporting documentation if requested by CSLB
  • Educational or training documentation if claiming credit toward the experience requirement
  • Required application and licensing fees
  • Fingerprints when required as part of the application process
  • Proof of the required Contractor Bond
  • Proof of Workers’ Compensation insurance or qualifying self-insurance
  • Any additional documents required by CSLB for the applicant’s particular business structure

Business names, qualifier information, bond documents, and insurance documents should match the information submitted to CSLB.

California Roofing Contractor License Application Process

The licensing process generally involves the following steps:

  1. Confirm your eligibility. Make sure you or your qualifying individual has the required roofing experience.
  2. Complete the CSLB application. Submit the appropriate Application for Original Contractor License along with the required application fee and experience certification.
  3. Complete fingerprinting requirements. Applicants and other personnel identified by CSLB may be required to submit fingerprints for a criminal background check.
  4. Receive approval to test. CSLB reviews the application and determines eligibility for the required examinations.
  5. Take the required examinations. Unless you qualify for a waiver, the qualifying individual must pass the Law and Business examination and the C-39 Roofing trade examination.
  6. Complete the asbestos open-book examination. New applicants must complete CSLB's asbestos open-book examination before CSLB can issue the license.
  7. Meet bond and insurance requirements. Obtain the required contractor bond and provide proof of Workers’ Compensation coverage.
  8. Pay the initial licensing fee and satisfy any remaining requirements. After passing the examinations, CSLB will provide instructions identifying the documents and fees required before issuing the license.
  9. Receive your C-39 Roofing Contractor License. Once CSLB approves the application and you meet all issuance requirements, the board can issue the license.

Examination Requirements and Preparation

Most applicants must pass two examinations:

  • Law and Business Examination
  • C-39 Roofing Trade Examination

The Law and Business examination covers topics related to operating a contracting business in California, while the C-39 examination focuses on knowledge applicable to roofing work.

Applicants should use CSLB's current examination study guides to prepare for the tests. Roofing contractors should be familiar with roofing systems and materials, installation and repair practices, safety requirements, estimating and planning, and other areas identified in the current C-39 study guide.

Certain applicants may qualify for examination waivers based on prior licensure or other circumstances. CSLB determines whether an applicant qualifies for a waiver.

Bond and Insurance Requirements

California requires licensed contractors to meet specific bonding and insurance requirements before CSLB can issue and maintain an active license.

Contractor License Bond

  • All California contractors must have a $25,000 Contractor's Bond on file with CSLB.
  • The bond protects consumers who may be harmed by certain violations of contractor licensing law and employees who are not paid wages owed to them.
  • Depending on how the business is structured and who serves as the qualifier, you may also need an additional $25,000 Bond of Qualifying Individual.
  • California LLC contractor licenses have additional requirements, including a $100,000 LLC employee/worker bond.

Workers’ Compensation Insurance

Workers’ Compensation is especially important for California roofing contractors.

All active C-39 Roofing Contractors must maintain Workers’ Compensation insurance or an approved Certification of Self-Insurance, even if they do not have employees.

This differs from the general rule that allows many California contractors without employees to file an exemption from Workers’ Compensation requirements. A standard no-employee exemption is not available to an active C-39 Roofing Contractor.

Coverage must remain in effect to maintain an active C-39 license. Failure to maintain the required Workers’ Compensation coverage can result in license suspension.

General Liability Insurance

California does not generally require a sole owner, partnership, or corporation holding a C-39 license to maintain General Liability insurance simply as a condition of CSLB licensure. However, customers, general contractors, property owners, lenders, and individual contracts frequently require proof of coverage.

General Liability insurance can help protect a roofing business against covered claims involving third-party bodily injury and property damage arising from its operations.

California-licensed LLC contractors must meet separate CSLB Liability insurance requirements. An LLC with five or fewer personnel of record must maintain at least $1 million in liability insurance, increasing by $100,000 for each additional person, up to $5 million.

Additional Insurance Considerations for California Roofers

Roofing operations involve significant exposures, from working at heights to transporting equipment and materials between projects. In addition to required Workers’ Compensation coverage and any General Liability requirements, roofing contractors may consider:

  • Commercial Auto insurance for company-owned vehicles
  • Contractors Tools & Equipment insurance for tools and mobile equipment
  • Commercial Umbrella or Excess Liability for additional Liability limits
  • Other coverage based on the size and scope of the roofing operation

Contracts and project owners may also establish insurance limits or coverage requirements beyond California's licensing requirements.
