Licensed Roofer in Washington State: How to Verify Before You Hire

Washington State requires all roofing contractors to register with the Department of Labor & Industries (L&I) before performing roofing work. Unlike some states that issue trade-specific roofing licenses, Washington uses a contractor registration system — but do not let the word "registration" fool you. Working without it is a gross misdemeanor carrying fines up to $5,000. With over 120,000 registered contractors in the state, the L&I database is your primary verification tool.

This guide explains how Washington State's contractor registration system works for roofers, how to look up any roofing contractor at lni.wa.gov, and what bond and insurance requirements apply.

Does Washington State require roofers to be licensed?

Washington State requires roofing contractors to be registered with L&I rather than holding a separate trade-specific license. The contractor registration is mandatory for any contractor performing roofing work for compensation, regardless of project size. The registration must be current and active at the time work is performed. There is no exemption for small roofing jobs or repairs.

Washington's system distinguishes between "general" and "specialty" contractor registrations. Roofing companies typically register as specialty contractors under the roofing trade. The L&I registration database shows the registration type, bond status, and insurance status for every registered contractor — all of which you can verify for free before hiring.

Where do I verify a roofer's registration in Washington State?

Verify any Washington roofing contractor through L&I's free contractor lookup at lni.wa.gov. The tool is called "Verify a Contractor, Electrician or Plumber." You can search by business name or registration number and see the registration status, expiration date, bond information, and liability insurance status. All of this is displayed in one screen, making it one of the more user-friendly state databases.

When reviewing the record, confirm four things: the registration status is "Active," the expiration date is current, the surety bond is listed as active, and the liability insurance is on file. L&I tracks all three simultaneously, so a single lookup tells you whether the contractor meets all basic requirements.

What bond is required for a Washington roofing contractor?

Washington State requires general contractors to carry a $12,000 surety bond as part of their L&I registration. Specialty contractors, including roofing-only companies, must carry a $6,000 bond. These bonds are verified through the L&I database and must be active at the time of any roofing work. The bond protects homeowners if a contractor causes property damage or fails to complete a contracted job.

The bond appears directly in the L&I contractor lookup results. If the bond shows as expired or missing, the contractor is not in compliance with Washington State law and should not be hired. This is not a technicality — an expired bond means there is no financial backstop if something goes wrong with the job.

What insurance is required for a Washington roofing contractor?

Washington State requires registered contractors to carry public liability and property damage insurance as a condition of registration. The L&I database shows whether this insurance is on file and current. Roofing contractors should also carry workers' compensation coverage — Washington State has one of the most robust workers' comp systems in the country, administered through L&I itself rather than private insurers.

For roofing work, workers' comp coverage is especially important. Roofing consistently ranks among the most dangerous trades. If a worker falls on your property without coverage, you could face civil liability. Washington's L&I workers' comp system covers most employees, but confirm the contractor has their account current before work starts.

What are the penalties for unregistered roofing work in Washington?

Performing contractor work without a valid L&I registration in Washington State is a gross misdemeanor punishable by fines up to $5,000. This applies to any roofing contractor who works without current registration, an expired registration, or a suspended registration. Washington takes this seriously — the state maintains a list of contractors with stop-work orders and actively enforces the registration requirement through field inspections.

For homeowners, the practical risks are substantial. Unregistered roofers cannot pull permits for work that requires them. Washington requires building permits for most full roof replacements, and local jurisdictions handle permit enforcement. Unpermitted roofing work can fail a home inspection during a sale, void manufacturer warranties on new roofing materials, and create problems with homeowner's insurance claims related to the roof.

What roofing work requires a permit in Washington State?

In Washington, most full roof replacements require a building permit from the local jurisdiction. Minor repairs — patching a few shingles, sealing a flashing joint — typically do not. The threshold varies by city and county, but any significant replacement of roofing materials on more than a small area generally triggers the permit requirement. Your contractor should know whether a permit is needed and should include the permit process as part of the job.

A registered Washington roofing contractor will be familiar with local permit requirements and will include permit fees in their estimate. If a contractor tells you no permit is needed for a full replacement, get written confirmation from your local building department before proceeding.

What should I ask a Washington roofer before hiring?

Ask for the contractor's L&I registration number. Then look it up at lni.wa.gov to confirm the registration is active, the bond is current, and liability insurance is on file. Ask whether the job requires a permit and who will pull it. Request a certificate of workers' compensation coverage. Any reputable Washington roofing contractor will answer these questions immediately — this is standard operating procedure for any registered professional.
