Once I pass the California C39 exam, can I legally install roofs on commercial & residential buildings?

Passing the California C39 exam is a crucial step, but it’s not the only requirement to legally install roofs on both commercial and residential buildings. Here’s a breakdown of what you’ll need:

• C39 License: Yes, passing the C39 exam qualifies you for a C39 Roofing Contractor license, which allows working on roofing projects exceeding $500.
  
  
• Business License: You’ll also need a business license to operate legally as a roofing contractor in California. This can be obtained from your local city or county government office.

Additional Considerations for Commercial Projects:

While the C39 license covers both residential and commercial roofing, there might be additional requirements for working on commercial buildings:

• Complexity: Commercially zoned buildings may have more intricate roof designs or require specialized materials. Ensure you have the experience and expertise to handle these projects.

• Insurance: Some clients, especially for larger commercial jobs, might require you to carry additional insurance coverage beyond what’s typically required for a C39 license.

Recommendation:

• Check with your local building department to confirm any specific licensing requirements for commercial roofing projects in your area.

• Consider contacting the CSLB for clarification on commercial roofing and the C39 license.

By fulfilling these requirements and having the necessary knowledge and experience, you’ll be legally authorized to take on roofing projects for both residential and commercial buildings in California.
