How to check a license in Washington

  1. Search by business name, registration number, or Washington UBI number.[1]
  2. Confirm the registration reads active and that roofing is the listed specialty, since a specialty registration only covers the trade named on it.[2]
  3. Check that a current bond is on file. Washington raised the specialty contractor bond to $15,000 in July 2024.[3]
  4. If the crew includes employees, confirm an active workers' compensation account in the same result.[4]

Warning signs

  • No written Notice to Customer handed over before a $1,000-plus job starts on a small residential property (four units or under).[5]
  • A registration that reads suspended, expired, or recently reinstated after a bond cancellation.[6]
  • Reluctance to give you the registration number so you can look it up yourself.
  • A discount that disappears if you don't sign during the same visit, or a demand for cash only.

Rules that protect you

  • Roofing is registered as one of dozens of specialty trades in Washington, and a specialty contractor can't hire subcontractors outside that trade.[2]
  • State law requires a written Notice to Customer before the crew starts on any $1,000-plus job at a small residential property of four units or under.[5]
  • The building permit itself comes from the local city or county, separate from L&I's contractor registration.[7]
