State registration

Washington Roofing License Requirements

Washington requires REGISTRATION with L&I, not licensure, and there is no exam and no dollar threshold — every contractor must register before advertising or performing work. A roofer registers as a SPECIALTY contractor (roofing being a single trade) unless the business runs more than one trade on a job, which triggers general contractor registration. The practical requirements are the surety bond ($15,000 specialty / $30,000 general), liability insurance of $200,000/$50,000 or $250,000 CSL, and the $150.20 registration fee. Consumers verify contractors at L&I's 'Verify a Contractor, Tradesperson or Business' tool.

Do roofers need a license in Washington?

Registration, not a license — Washington keeps a state register of roofers

The state keeps a public list and collects a filing — usually with a bond and proof of insurance — but does not test competence the way a licence does.

The rule in detail

State-level requirement: State registration
Licensing authority: Washington State Department of Labor & Industries (L&I), Contractor Registration
Class covering roofing: Specialty contractor registration for roofing (a single trade). A GENERAL contractor registration is required instead where the business uses more than one building trade or craft on a single job, project, or building permit — RCW 18.27.010.
Dollar threshold: No dollar threshold. RCW 18.27.020 states plainly that 'Every contractor shall register with the department' — registration is required regardless of project value.
Statute or rule: RCW ch. 18.27 (Registration of Contractors); definitions of general vs. specialty contractor at RCW 18.27.010; registration mandate at RCW 18.27.020.
Bond: Continuous surety bond: $30,000 for general contractors, $15,000 for specialty contractors. (These amounts rose on July 1, 2024 from $12,000 and $6,000.) The bond is purchased from a surety company, not from L&I, and must carry the exact business name.
Insurance: General liability of either $200,000 public liability plus $50,000 property damage, or $250,000 combined single limit. L&I must be named as certificate holder.
Reciprocity: No published reciprocity arrangement for roofing.

Local licensing and permits in Washington

L&I registration is a statewide baseline, not a competency licence — there is no roofing exam. Cities and counties still issue building permits for roofing and check the L&I registration number on permit applications; many cities (Seattle among them) also require a local business licence. The registration number must appear on all advertising, business cards, estimates, bid proposals, vehicles and internet ads. Some trades regulated separately by L&I — electrical, plumbing, elevators, asbestos, boilers, mobile-home installation — carry additional education, exam and licensing requirements beyond contractor registration.

Permitting is a separate system from licensing, and it is almost always local. In Washington, as nearly everywhere in the United States, a full roof replacement is treated by the adopted building code as work requiring a permit and a final inspection, while small repairs are often exempt below a threshold the local code sets. The building department for the city or county where the house sits is the only body that can tell you which side of that line your job falls on.

The two questions are not the same question

Licensing asks whether this contractor is permitted to sell roofing work in Washington. Permitting asks whether this specific job on this specific building may proceed. A contractor can be perfectly licensed and still be doing unpermitted work, and an unpermitted roof tends to surface at a sale, at a claim, or at a warranty dispute — years later, when it is expensive.

If you are hiring a roofer in Washington

●Check the credential at the source. Search the Washington public register for the exact legal entity that will sign your contract — not the salesperson, and not the name painted on the truck.
●Ask for certificates of insurance directly from the insurer or agent. General liability and workers’ compensation both matter, and roofing carries some of the highest comp premiums of any trade — which is exactly why some operators go without. An injury on an uninsured crew can find its way to your policy.
●Confirm who is pulling the permit. It should be the contractor, in their own name. An invitation to pull it yourself as the homeowner moves the code liability onto you, and is often a sign the contractor cannot pull it.
●Get the scope in writing before any deposit changes hands. Tear-off versus overlay, decking replacement priced per sheet, underlayment and ice-and-water coverage, ventilation, flashing, and who hauls the debris. Most roofing disputes are scope disputes wearing a different hat.
●Be careful after a storm. Door-knocking crews follow hail. Before signing anything that assigns your insurance benefits or commits you to a contractor contingent on a claim being approved, read it twice and check the cancellation terms.

If you are a roofing contractor working in Washington

Washington holds a state-level requirement, so the first question is whether your work sits inside the classification described above and, where a dollar figure applies, whether the contract value crosses it. Thresholds are normally written against the total value of the contract or the project rather than an individual invoice, so splitting a job into pieces to stay underneath is the specific evasion those statutes exist to catch.

Two consequences of getting this wrong are worth knowing regardless of the state. Contracting without a required credential is commonly a misdemeanour offence, and in most states an unlicensed contractor cannot enforce the contract or file a mechanic’s lien — so an unpaid job simply stays unpaid, with no legal route to collect. Confirm your position with the board before you bid, not after.

Note on this entry

Bond amounts, insurance minimums, the $150.20 fee and the registration-not-licence framing were confirmed on lni.wa.gov; the general/specialty split and the absence of any dollar threshold were confirmed against RCW 18.27.010 and RCW 18.27.020 on app.leg.wa.gov. Reciprocity was not addressed on the pages reviewed and is left null rather than asserted.

Checked August 2026. Licensing rules change — dollar thresholds get raised, boards get reorganised, and statutes get amended mid-session. This page is a research summary, not legal advice, and it is not the authority on anything.
