Washington’s diverse climate creates year-round demand for roofing professionals. From heavy rain and wind in Western Washington to snow and temperature extremes east of the Cascades, residential and commercial roofs must withstand a variety of weather conditions. Roofing contractors play an important role in installing, maintaining, repairing, and replacing these systems.

If you plan to operate a roofing business in Washington, you must understand the state’s contractor registration requirements before advertising, bidding on, or performing work. Washington does not issue a separate state roofing contractor license. Instead, construction contractors must register with the Washington State Department of Labor & Industries (L&I).

This guide explains Washington’s contractor registration requirements, application process, bond and insurance requirements, and other considerations for roofing contractors.

Who Needs to Register as a Roofing Contractor in Washington State?

Washington requires construction contractors to register with L&I before they can advertise, bid on, or perform construction work. Roofing is specifically recognized as a contractor specialty under Washington law.

Unlike some states, Washington does not establish a minimum project-dollar threshold before contractor registration is required. If you operate a roofing contracting business, you generally must register before performing contracting work.

Roofing contractors typically register as either a Specialty Contractor or a General Contractor, depending on the scope of their operations.

Washington State Roofing Contractor Registration Requirements

Washington has two primary construction contractor classifications:

Specialty Contractor: A roofing contractor that limits its operations to roofing can register under the roofing specialty. Specialty contractors may perform work only within their registered specialty and generally cannot hire subcontractors to perform other specialties.
General Contractor: A general contractor can perform multiple construction trades and may hire subcontractors in multiple specialties. A roofing business that performs work beyond the roofing specialty or intends to subcontract portions of projects may need to register as a General Contractor.

Washington defines the roofing specialty to include installing and repairing materials that create watertight and weather-resistant surfaces for roofs and decks. The scope includes roofing accessories, plywood, coping, flashing, valleys, gravel stops, roof insulation panels above roof decks, metal roofing systems, shakes, shingles, roof tile, slate, waterproofing and membrane materials, and roofing-related architectural sheet metal.

The roofing specialty does not authorize structural repairs to trusses, beams, or joists.

Eligibility and Business Requirements

To register as a construction contractor in Washington, you must establish and properly register your business before completing the contractor registration process.

Depending on your business structure, this generally includes:

Choosing your business structure and legal business name
Registering your business with the Washington State Department of Revenue and obtaining a Uniform Business Identifier (UBI)
Registering an LLC, corporation, or other applicable entity with the Washington Secretary of State
Selecting either General Contractor or Specialty Contractor registration
Selecting Roofing as your specialty if registering as a Specialty Contractor
Obtaining the required contractor surety bond or approved Assignment of Account
Purchasing the required General Liability insurance
Completing the Washington Application for Construction Contractor Registration

Each principal owner, member, partner, or corporate officer identified on the application must complete the appropriate affidavit and provide the required identifying information.

Experience and Examination Requirements

Washington does not require roofing contractors to demonstrate a specific number of years of roofing experience to obtain a standard construction contractor registration. The state also does not require a roofing trade examination as part of the registration process.

Even though no exam or specific experience requirement applies, roofing contractors must understand and comply with applicable building codes, safety requirements, manufacturer specifications, permit requirements, and other laws governing their work.

Practical training may include:

Working under experienced roofing contractors
Apprenticeship or other on-the-job training
Roofing manufacturer training and certifications
OSHA and Washington workplace safety training
Industry association education
Training in specific roofing systems and materials

Required Documentation

To register as a roofing contractor with Washington L&I, you generally need:

A completed application for Construction Contractor Registration
Your business registration and UBI number
Your contractor classification and specialty, when applicable
An original Washington Continuous Contractor Surety Bond or qualifying Assignment of Account
A Certificate of General Liability insurance meeting Washington’s minimum requirements and listing L&I as the certificate holder
Required information and notarized signatures for the business principals
The applicable contractor registration fee

Your business name must match across your Department of Revenue registration, contractor registration application, bond, and insurance documentation.

Washington State Contractor Registration Application Process

The process generally involves the following steps:

Establish your business. Choose your business structure and register the business with the appropriate Washington agencies.
Determine your contractor classification. Decide whether your roofing operation should register as a Specialty Contractor under the roofing specialty or as a General Contractor.
Obtain the required bond. Secure the appropriate Washington Continuous Contractor Surety Bond or establish an approved Assignment of Account.
Purchase General Liability insurance. Obtain General Liability coverage that meets Washington’s minimum contractor registration requirements and make sure L&I is listed as the certificate holder.
Complete the contractor registration application. Provide your business information and obtain the required notarized signatures.
Submit your application and supporting documents. Submit applications through an L&I office or by mail, per current L&I instructions.
Pay the registration fee. Pay the applicable L&I contractor registration fee.
Maintain your registration. Keep your bond and General Liability insurance active and renew your contractor registration when required.

Once registered, contractors must include their contractor registration number in advertising, estimates, bid proposals, business cards, internet advertising, and other required business communications.

Bond and Insurance Requirements

Washington requires construction contractors to maintain both a contractor surety bond and General Liability insurance as conditions of registration.

Contractor Surety Bond

Current required bond amounts are:

General Contractor: $30,000
Specialty Contractor: $15,000

Instead of purchasing a surety bond, contractors may use an approved Assignment of Account that meets L&I requirements.

General Liability Insurance

Washington contractors must maintain at least:

$200,000 in public liability coverage and $50,000 in property damage coverage; or
$250,000 combined single-limit coverage

The Certificate of General Liability Insurance must identify L&I as the certificate holder. Contractors must maintain the required insurance and bond to keep their registration active.

These are state minimums for contractor registration. Roofing contractors may need or choose higher General Liability limits based on their projects, contracts, customers, or overall business exposures.

Workers’ Compensation Requirements

Roofing contractors with covered workers generally must establish a Washington Workers’ Compensation account through L&I and report and pay premiums for those workers.

Washington’s rules regarding workers and independent contractors are strict. Simply paying someone using a Form 1099 does not automatically make that person an independent contractor for Workers’ Compensation purposes. Businesses should determine whether workers satisfy Washington’s requirements for an exemption before treating them as independent contractors.

Owner-operators and certain other individuals may qualify for exemptions depending on their circumstances.

Additional Considerations for Washington Roofing Contractors

Registration with L&I does not eliminate other requirements that may apply to individual projects.

Roofing contractors should verify:

Local building permits and inspection requirements
Applicable Washington State Building Code requirements
Workplace safety requirements
Fall protection requirements for roofing operations
Requirements involving lead or asbestos when working on certain existing structures
Any additional licensing or certification required when work extends beyond the scope of the roofing specialty

Specialty roofing contractors should also pay close attention to their registration scope. Washington’s roofing specialty does not authorize structural repair of trusses, beams, or joists. Contractors performing work outside the roofing specialty may need a different specialty registration, General Contractor registration, or other appropriate authorization.
