License records for Palo Alto

0 of Palo Alto's roofing licenses were issued within the past 24 months.

A recent license isn't a warning sign on its own, but it's worth asking a newer Palo Alto company how long its crew has actually worked in roofing.

Either way, check the Palo Alto number yourself rather than taking a business card's word for it.

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

  • No pocket license or photo ID offered when someone arrives to give you a bid in person.[3]

  • Pressure to waive or rush past your three-day right to cancel after signing.[4]

Rules that protect you

  • 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]
