1. Verify Washington State Roofing License

In Washington, all roofing contractors are required to be registered with the Washington State Department of Labor & Industries (L&I). This ensures the contractor meets state standards for business practices and safety compliance.

Before signing any contract, ask for your roofer’s Washington State Contractor License number and verify it on the L&I Contractor Lookup. A valid license not only confirms the contractor’s legitimacy but also helps protect you from unqualified or fraudulent operators.

Axiom D7 is fully licensed, bonded, and insured in the state of Washington — giving our clients peace of mind that every project meets regulatory and safety standards.

 

2. Confirm Insurance and Bonding

Commercial roofing projects often involve significant costs, materials, and equipment. Proper insurance coverage protects both the property owner and the contractor in case of accidents or property damage.

You should always verify that your roofing contractor carries:

• General Liability Insurance (to protect your property)
• Workers’ Compensation Insurance (to cover employees on-site)
• Bonding (to safeguard against incomplete or substandard work)

At Axiom D7, we maintain comprehensive insurance and bonding on every project — because your protection is as important as your roof’s durability.

 

3. Ask for Local Referrals and Project References

A reputable commercial roofer should have a solid track record of successful projects in the Seattle area. Ask for a list of past clients or local references — ideally for buildings similar to yours in size or type.

When reviewing referrals:

• Check for long-term client relationships.
• Ask about project timelines, workmanship quality, and communication.
• Look for reviews that mention performance in Seattle’s rainy climate.

Axiom D7 has earned trust across the Seattle business community by delivering durable, weather-resistant roofing systems tailored to local conditions. From flat roofs on industrial buildings to multi-story waterproofing solutions, our expertise speaks through our satisfied clients.

 

4. Evaluate Experience with Commercial Roofing Systems

Not all roofing contractors specialize in commercial properties. Commercial roofs require different materials, installation techniques, and maintenance strategies than residential systems.

Ensure your contractor has experience with:

• Flat and low-slope roofs
• TPO, PVC, and EPDM membranes
• Roof coatings and waterproofing systems
• Preventive maintenance programs

At Axiom D7, we focus exclusively on commercial roofing — offering full-service installation, repair, and maintenance for businesses throughout the Seattle area. Our team understands how to maximize roof performance and longevity under Seattle’s wet, windy, and unpredictable weather patterns.

 

5. Review Warranties and Maintenance Options

A professional roofing contractor will stand behind their work. Make sure your roofer provides both a manufacturer’s warranty on materials and a workmanship warranty on installation.

Axiom D7 offers ongoing roof maintenance programs to extend the lifespan of your system and help you avoid costly repairs. Our proactive inspections ensure your roof stays watertight and compliant with warranty terms year-round.
