143 Roofing Companies in Washington: Public Records & Data

In Washington State, roofing contractors must register with the Department of Labor and Industries under the Contractor Registration program. All contractors performing work valued at $500 or more must be registered as either a general contractor or specialty contractor. Roofing companies typically register as specialty contractors. To register, applicants must obtain a surety bond of $6,000 for specialty contractors, secure general liability insurance with a minimum of $50,000 in coverage, and pay a registration fee. The registration must be renewed every two years, and contractors must maintain active bonding and insurance throughout the registration period.

Washington does not require a statewide trade examination specifically for roofing contractors, which distinguishes it from many other states. However, contractors must have a valid Unified Business Identifier (UBI) number from the Washington Secretary of State and must comply with all applicable state business licensing requirements. Workers must also be covered under the contractor's workers' compensation policy through the Department of Labor and Industries, or the contractor must verify that workers are properly classified as independent contractors meeting strict criteria.

Beyond state registration, some cities and counties in Washington impose additional local business license requirements. For example, cities such as Seattle and Bellevue may require separate municipal business licenses and may have additional insurance or bonding thresholds. Contractors should verify local requirements in each jurisdiction where they intend to work. Failure to maintain proper registration can result in fines, stop-work orders, and prohibition from bidding on projects. Homeowners are encouraged to verify a contractor's registration status through the Department of Labor and Industries online lookup tool before hiring.
