How to check a roofer is really local to Washington

A real local roofer has a street address in Washington you can find on a map, a local phone number, a Washington Department of Labor & Industries (L&I) registration you can look up in a minute, a BBB profile under the same legal name, finished jobs in towns near you, and a written contract that names the company doing the work. Eight checks, about ten minutes.

Why it matters

Some roofing websites aren't roofing companies. They collect your details and sell the lead to whoever will pay for it, sometimes to a contractor you have never heard of, sometimes to one from another state. The site looks local; the company behind it may not be. Ten minutes of checking before you book a visit tells you who you are actually dealing with.

1. Find a real street address in Washington

A local company can tell you where its office is. Look for a street address in Washington, not just a list of cities it "serves", and look the address up on a map. A website with only a toll-free number and a contact form, and no street address, is a reason to ask more questions.

2. Look at the phone number

A roofer working in your area will usually answer on a local number. A toll-free number on its own doesn't mean anything is wrong, but it doesn't tell you where the company is. The area codes to expect:

Seattle: 206
Tacoma and south King County: 253
Bellevue, the Eastside and Everett: 425
The rest of western Washington, from Bellingham and the islands to Olympia, Kitsap and Vancouver: 360
564 is an overlay on all four western Washington codes
Eastern Washington, including Klickitat County: 509

3. Look up the L&I registration

Washington requires construction contractors to register with the Department of Labor & Industries (L&I) and to be bonded and insured: a $30,000 bond for a general contractor or $15,000 for a specialty contractor (since July 1, 2024), and liability insurance. L&I's "Verify a Contractor" lookup shows whether a registration is active, the workers' comp account, safety violations and lawsuits against the bond.

Search the legal name on the quote, not the website name, and check that the registration is active and how long it has been. Washington's new Homeowner Recovery Fund, for court judgments ordered after July 1, 2026, can pay owner-occupants of a home of four or fewer units up to $25,000, depending on available funds, but only when the contractor was registered with L&I. Condominiums are excluded.

4. Oregon and Idaho, briefly

Oregon requires contractors to hold a current license from the Construction Contractors Board; check it on the CCB's license search. Idaho requires contractors to register with the Division of Occupational and Professional Licenses (DOPL) for construction jobs over $2,000. A company that works across state lines should hold each state's license or registration, not just one.

5. Check the company's BBB profile

Search the legal name on bbb.org. A real profile shows the business address, how long the company has been in business, and any complaints and how they were answered. Match the address and legal name to the quote.

6. Ask where their recent jobs are, on a map

A company with a real install record near you can name the towns, show you photos of finished roofs close to your house, and put you in touch with past customers. Stock photos, and reviews with no town attached, tell you nothing.

7. Get it in writing, from the company that does the work

The quote, the contract and the warranty should all name the same legal company, the one that installs the roof, and the contract should carry its L&I registration number. Read the warranty's exclusions before you sign. On Washington residential work:

Get a written contract with the scope, materials, price and payment schedule, as L&I advises
For work of $1,000 or more on a home of four or fewer units, the contractor must give you a disclosure statement before work starts (RCW 18.27.114)
The disclosure explains the contractor's registration and bond, your right to withhold retainage, and how unpaid suppliers or subcontractors can lien your property
Get at least three written bids and compare them carefully, as L&I advises

Questions, answered

How can I tell if a roofing website is a real local company?

Look for a street address in Washington you can find on a map, a local phone number, a L&I registration you can look up, a BBB profile under the same legal name, and finished jobs in towns near you. A lead-generation site usually can't show all five.

Do roofers need a license in Washington?

Yes. Washington requires construction contractors to register with the Department of Labor & Industries (L&I) and to be bonded and insured: a $30,000 bond for a general contractor or $15,000 for a specialty contractor (since July 1, 2024), and liability insurance. L&I's "Verify a Contractor" lookup shows whether a registration is active, the workers' comp account, safety violations and lawsuits against the bond.

How do I check a Washington contractor's registration?

Search the legal name or registration number on L&I's "Verify a Contractor, Tradesperson or Business" lookup. It shows whether the registration is active, the workers' comp account, safety violations and lawsuits against the bond.

What paperwork should a Washington roofer give me?

A written contract, and for residential work of $1,000 or more on a home of four or fewer units, a disclosure statement before work starts (RCW 18.27.114) explaining the contractor's registration and bond, retainage, and lien rights.
