A general contractor can do roofing in California only if they hold a C-39 roofing license or work under a licensed roofer’s supervision. California law requires anyone doing roofing work to have proper licensing. This means a general contractor with just a C-10 license cannot legally install or replace roofs on their own. You need to hire a licensed roofer or a general contractor who also has a C-39 roofing license. The roofing industry is serious about this rule to protect homeowners and ensure quality work.
What License Do You Need in California?
California requires two main contractor licenses for roofing work. A C-10 general contractor license does not cover roofing. You must have a C-39 roofing license to do roof work legally.
A C-39 license means the contractor passed an exam about roofing materials, safety, and building codes. They also need insurance and bonding. According to the U.S. Bureau of Labor Statistics, there are 135,140 roofers employed in the U.S., with an average hourly wage of $26.85. California roofers earn even more, averaging $33.17 per hour or about $69,000 per year.

Why Does California Care About Roofing Licenses?
Roofing is dangerous work. According to OSHA, over 50% of all construction fall deaths involve roofers. California wants to make sure only trained professionals do this job.
Roofs protect your entire home from water and weather. A bad roof installation can lead to leaks, mold, and costly repairs. Licensed roofers know building codes and safety rules. They carry insurance in case something goes wrong. According to RubyHome, the average roof replacement cost is $9,526, with a range from $5,868 to $13,217. You want someone qualified doing work that costs this much.
What If a General Contractor Wants to Do Roofing?
A general contractor can hire a licensed C-39 roofer to do the roofing work. The general contractor acts as the project manager. They hire the roofer, schedule the work, and ensure everything meets code. This is legal and common.
The general contractor cannot do the roofing themselves without a C-39 license. Doing roofing work without a license is illegal in California. You could face fines or have to redo the work. According to the U.S. Bureau of Labor Statistics, the median annual wage for roofers is $50,030. This shows roofing is a skilled trade that requires training and certification.
How to Hire the Right Roofer in California
Always ask to see a contractor’s C-39 license before hiring. Check that their license is current and active with the California Department of Consumer Affairs. Ask for proof of liability insurance and workers’ compensation coverage.
Get multiple quotes from licensed roofers. According to RubyHome, roof installation costs range from $4 to $40 per square foot. For a 1,700 square foot roof, that means $6,800 to $68,000 depending on materials and quality. Compare prices, materials offered, and warranties. Make sure the roofer can explain the work in simple terms. A good roofer will answer all your questions and give you a written estimate.
