- An active California CSLB license with a roofing (C-39) classification.

Checking a commercial roofing contractor
License
Look up the contractor on the Contractors State License Board site. Confirm the license is active, includes roofing, and shows current bond and workers’ comp status.
Insurance
Ask for certificates of liability and workers’ comp insurance issued directly by the insurer, naming you as certificate holder.
Manufacturer standing
If you want a manufacturer’s system warranty, confirm the contractor is authorized to install that system.
References
Ask for references on buildings similar to yours in size and roof type, and call them.
Scope
Compare bids line by line: system, thickness, insulation, tear-off, flashing details and warranty.
Signs to walk away
No license number on the bid
California contractors must show their license number. Missing or unverifiable means stop.
One-number bids
A single price with no line items hides what’s included and what isn’t.
One answer for every roof
A contractor who recommends the same system for every building is selling a product, not solving your problem.
Pressure and big deposits
Urgency without a clear reason, or large upfront payments, are warning signs.

Frequently asked questions
How do I check a commercial roofer's license in California?
Use the Contractors State License Board's license lookup to confirm the license is active, includes roofing, and shows current bond and workers' comp status.
Do I need a manufacturer-authorized contractor?
If you want a manufacturer's system warranty, yes. Many manufacturers only issue those warranties through contractors they authorize.
How many bids should I get for a commercial roof?
At least two or three written, line-item bids, so you can compare scope as well as price.
Are 'best roofer' lists reliable?
Often not. Many are paid placements. Verify license, insurance and references yourself.
