How to check a license in California

  1. Search using the license number, the business name, or the name of whoever qualifies the license.[1]
  2. Confirm the classification reads C-39, the roofing classification, rather than relying on a general "B" license for a single-trade roof job.[2]
  3. Check that workers' compensation is shown on file; C-39 roofers must carry it whether or not they have employees.[2]
  4. Review the license's status and any disciplinary history displayed on the same result page.[1]

Warning signs

  • A license status that reads inactive, revoked, or suspended, or a business name that doesn't match your bid.[1]
  • No pocket license or photo ID offered when someone arrives to give you a bid in person.[3]
  • A deposit bigger than the state's own cap, the smaller of a tenth of the job's price or $1,000, without a bond on record to explain the extra.[4]
  • Pressure to waive or rush past your three-day right to cancel after signing.[4]

Rules that protect you

  • California requires a $25,000 bond for a C-39 license, on top of mandatory workers' compensation coverage for every C-39 roofer.[2]
  • Any roofing job with combined labor and materials of $500 or more requires a C-39-licensed contractor by law.[2]
  • A written contract is required for home improvement work over $500, with a right to cancel within three days of signing.[4]

Before you let anyone on your {city} roof

  1. Does the name on the bid match the name on the license exactly?
  2. Is the license active, and when does it expire?
  3. Does the company have a local address, or only a cell phone number and an out-of-state plate?
  4. Did they contact you first, unprompted, right after a storm?
  5. Are they asking for full payment, cash only, or a deposit before any paperwork is signed?
  6. Will they give you a written, itemized estimate before you commit to anything?
