How to Start a Roofing Business in Washington: L&I Roofing Specialty Registration, $15,000 Bond and the No-Structural-Repair Limit

If you search for a washington roofing license, you will find plenty of pages promising one. Here is the direct answer: Washington does not issue a separate roofing license. Roofing is an L&I specialty registration that you add to your contractor registration. It works like a license in practice, because you cannot legally advertise or perform roofing work without it. It also comes with a $15,000 surety bond, $250,000 combined single limit insurance, and a scope limit that excludes structural repair.

This guide walks through the formation sequence for a roofing company in Washington, in the order most owners find easiest to manage. It covers the state paperwork, the L&I registration, the bond and insurance, workers' compensation, and the local and safety requirements that come after.

What You Need Before You Start

Gather these items before you open any state portal. Most of the delays in this process come from missing information, not from the agencies themselves.

• Government-issued photo ID and your Social Security number, or a federal EIN if you plan to form an LLC or corporation
• Two or three business name options, each checked against the Secretary of State business search
• A physical street address in Washington for your registered agent (PO boxes and private mailbox addresses are not accepted)
• An email address for your registered agent
• A surety bond quote for $15,000
• An insurance quote showing $250,000 combined single limit coverage
• A list of the roofing work you plan to perform, including whether any of it involves structural framing
• A debit or credit card for state fees

Step 1: Choose Your Business Structure

Your structure determines which state filings you owe. Sole proprietors and general partnerships do not file with the Secretary of State. If you operate under a name other than your own legal name, you still register the trade name through the Department of Revenue, as covered in Step 3.

Most roofing owners who want liability separation from their personal assets choose an LLC or a corporation. Both are formed through the Corporations and Charities Filing System (CCFS). Washington has no corporate income tax and no personal income tax on wages. Instead, nearly every business pays the state business and occupation (B&O) tax, a gross receipts tax with no deduction for labor or materials. Many cities levy their own B&O tax on top of the state tax. The structure choice has tax and liability consequences, so talk with an attorney or CPA before you file.

Step 2: Form Your LLC or Corporation Through CCFS

If you choose an LLC, the formation document is a Certificate of Formation with Initial Report. A corporation files Articles of Incorporation with Initial Report. The current filing fee for either is $180, and both are filed online through CCFS at ccfs.sos.wa.gov.

Naming rules matter. An LLC name must include Limited Liability Company, Limited Liability Co., L.L.C., or LLC, under RCW 23.95.305. The name must be distinguishable from every other business name on record with the Secretary of State. It also cannot contain words such as bank, banking, banker, trust, or cooperative, or certain combinations of building, savings, loan, home, association and society. Check availability with the Secretary of State business search before you commit to a name.

Three cost options apply at this stage:

• Name reservation: $30, which holds a name for 180 days while you finish your paperwork.
• Expedited service: $100 per business entity, generally processed within three business days, available online at checkout or by mail with the envelope marked EXPEDITE.
• Same-day service: The fee schedule lists same-day service at $150 per entity. The Corporations Division currently charges front-counter same-day transactions received before 3:30 p.m. at the $100 expedited rate, and says it will give 30 days notice on its website before implementing the $150 fee. Confirm the current rate before you pay.

Every business must also name a registered agent in Washington under RCW 23.95.415. The agent can be commercial or noncommercial, must consent to serve, must provide an email address, and must have a physical street address in Washington. There is no fee to change the registered agent or registered office later.

Step 3: Register With the Business Licensing Service

The Washington Department of Revenue runs a statewide Business License Application through its Business Licensing Service (BLS). It issues your 9-digit Unified Business Identifier (UBI) and handles state and city endorsements in one filing. For a roofing company, you should expect to need it. A business license is required if you need city, county, or state endorsements, operate under a name other than your full legal name, plan to hire employees within 90 days, sell anything subject to sales tax, expect gross income of $12,000 per year or more, or owe any tax or fee to the Department of Revenue.

Corporations, LLCs, LLPs, and partnerships must file with the Secretary of State before submitting the Business License Application. Sole proprietors can apply directly.

Current costs and timing:

• Processing fee: $50 to open a business, plus separate endorsement fees. Confirm endorsement amounts for your city before you apply.
• Processing time: Online applications take about 10 business days, and 2 to 3 weeks longer when city or state endorsements need approval. Mailed applications can take up to six weeks.
• Trade names: $5 for each trade name registered, plus the BLS processing fee. Adding a trade name to an existing business carries a $10 processing fee. Trade names are registered with the Department of Revenue, not the Secretary of State or your county. Register at dor.wa.gov.

Apply through the Department of Revenue business license page. Also ask BLS how sales tax applies to the invoices you plan to issue. The state base sales tax rate is 6.5%, but how it applies to roofing labor and materials is a question to confirm with the Department of Revenue.

Step 4: Register as a Contractor With L&I and Add the Roofing Specialty

This is the step that matters most for roofers. The Department of Labor and Industries (L&I) registers contractors, and roofing is one of its specialty registrations. Washington's contractor statute, RCW 18.27.010, names installing or repairing roofing in its definition of a contractor. That is why advertising roofing work without registration is a gross misdemeanor under RCW 18.27.010 and 18.27.020.

The roofing specialty covers installing and repairing roofing and weatherproofing material for roofs and decks, including roofing-related architectural sheet metal. It does not cover structural repair of trusses, beams, or joists. Siding is a separate specialty.

The L&I contractor registration application fee is $150.20 for a two-year registration, and roofing is one of the specialties defined in WAC 296-200A-016(44). Confirm the current amount at lni.wa.gov before you budget.

Treat the advertising rule as a hard line. Do not list roofing on your website, truck signs, social media profiles, bids, or business cards until your registration is active.

Step 5: Post the $15,000 Contractor Bond

Roofing requires a $15,000 surety bond. You buy it from a surety company or a bond agency, and the surety files it with L&I as part of your registration. The bond protects customers and others who suffer losses from your work, subject to the bond's terms.

A bond is not insurance for you. If the surety pays a claim, you must repay the surety. Premiums vary with your personal credit, business history, and experience, so get at least two or three quotes. Ask each agent whether the quote is for the exact $15,000 bond L&I requires for the roofing specialty.

Step 6: Buy $250,000 Combined Single Limit Insurance

L&I requires contractors to carry general liability insurance of either $250,000 combined single limit or $200,000 public liability plus $50,000 property damage. A combined single limit means one dollar cap per occurrence that applies to bodily injury and property damage together. A single fall from a roof or a damaged neighbor's property can use up that limit quickly, so ask your broker how the policy handles multiple claims.

Request a certificate of insurance that shows the $250,000 combined single limit. You will need that certificate for your L&I file. Confirm the current insurance requirement with L&I before you buy, because the requirement is set by the agency.

Step 7: Set Up Workers' Compensation Through the L&I State Fund

Workers' compensation in Washington runs through the L&I state fund. Premiums are set by risk class and by the hours your workers record, which makes roofing one of the higher-cost classes. Ask L&I for your roofing class rate before you set prices, because the rate directly affects your bids.

Track hours carefully from the first day you hire anyone. Underreported hours create audit problems, and payroll reporting errors are expensive to correct. If you hire employees, also register with the Employment Security Department for unemployment insurance, and confirm the timing and requirements directly with ESD.

Step 8: Understand the No-Structural-Repair Limit

The roofing specialty stops at the roof system. You can replace shingles, underlayment, flashing, roof decks, and roofing-related architectural sheet metal. You cannot perform structural repair of trusses, beams, or joists under this specialty.

This limit causes real problems on jobs. A common scenario is a re-roof where the crew finds rotted rafters or a sagging truss. Stop, document the condition with photos, and tell the customer in writing before doing any framing work. Structural work may require a different registration or a registered general contractor. Confirm with L&I which registration covers the work before you agree to it in a contract.

Step 9: Plan for Lead-Safe Requirements on Pre-1978 Homes

If your roofing work involves homes built before 1978, you need Department of Commerce lead-safe firm certification. The certification costs $25 and lasts five years, under WAC 365-230-260 and 365-230-360. Get it before you bid on pre-1978 jobs, and ask your crew leads to confirm the lead-safe work practices required for the job.

Step 10: Meet Safety Standards and Local Requirements

Fall protection is the core safety issue in roofing. L&I's Division of Occupational Safety and Health (DOSH) enforces its construction safety standards in chapter 296-155 WAC. Write a site-specific fall protection plan, train your crew, and keep records. Inspectors look at these first.

Local requirements add another layer. Washington has 39 counties and 281 incorporated places, which means each city or county sets its own rules. About 54 cities levy their own B&O tax, and the Department of Revenue does not administer those local taxes. Check with the building department in each city or county where you plan to work about roofing permits and any local business requirements. Permit fees vary by jurisdiction, so confirm them locally.

Step 11: Calendar Your Recurring Deadlines

Missing a recurring deadline can cost more than the original filing. Set reminders for each of these:

• Annual report: $70, due by the last day of the month in which your LLC or corporation was originally formed or registered, every year. You can file up to 180 days early. A late filing carries a delinquency fee, bringing the total to $95.
• L&I registration fee: $150.20 for two years. Confirm the renewal date when you register.
• Bond and insurance: Renew both before expiration. A lapse can halt your registration.
• Registered agent: Keep your agent's contact information current and confirm the agent is still willing to serve.

Common Mistakes to Avoid

• Searching for a roofing license. There is no separate roofing license. Look for the L&I specialty registration instead, and ask L&I to confirm your status.
• Advertising before registration. Unregistered advertising is a gross misdemeanor under RCW 18.27.010 and 18.27.020.
• Assuming roofing covers siding or framing. Siding is a separate specialty, and structural repair of trusses, beams, or joists is outside the roofing scope.
• Using a PO box for the registered agent. Washington does not accept PO boxes or private mailbox addresses.
• Skipping the trade name registration. If you operate under a name other than your legal name, register it with the Department of Revenue, at $5 per trade name plus the processing fee.
• Forgetting city B&O taxes. The state tax is only part of your gross receipts obligation in many cities.
• Bidding pre-1978 jobs without lead-safe certification. Get the $25 certification before the first bid.
• Underreporting hours to L&I. Workers' compensation premiums depend on accurate hours, and errors surface at audit.

What Results to Expect

Completing these steps may help you operate legally and bid on roofing work with the paperwork in place. Many owners find that the registration, bond, and insurance make their company easier to trust with commercial and property management clients, who often ask for proof of registration before they sign. Results depend on your market, your pricing, your crew, and the quality of your work, so treat the registration as a foundation rather than a guarantee of new business.

On timing, the BLS and Secretary of State processing estimates in this guide are current, but L&I processing times and bond approval times vary. Ask each agency for its current timeline before you set a start date.

Next Steps

Start with the name check and the Secretary of State filing, then move to BLS and L&I. Keep a folder with receipts, certificates, and confirmation numbers for every filing. Helpful resources include:

• Washington Secretary of State, Corporations and Charities Division
• Washington State Department of Revenue
• Washington Department of Labor and Industries
• Washington Small Business Development Center, which offers free or low-cost business advising
• SBA Seattle District Office

Because roofing businesses carry real liability and tax exposure, talk with a qualified Washington attorney about your entity choice and contracts, and with a CPA about B&O, sales tax, and payroll obligations.
