Permit Process
Project Review & Documentation
Start by gathering project details, including roof measurements, material specifications, and contractor information. For commercial projects, architectural drawings may be required. Review Seattle's specific requirements for roofing materials and installation methods.
Permit Application Submission
Submit your permit application through SDCI's online portal or in person. Include contractor licensing information, project details, and any required drawings. For complex projects, pre-application meetings may be recommended.
Plan Review & Approval
SDCI reviews your application for compliance with building codes, energy standards, and zoning requirements. This process typically involves checking structural calculations, material specifications, and installation methods.
Permit Issuance & Fees
Once approved, pay the permit fees based on project valuation and scope. The permit will include inspection requirements and any special conditions for your roofing project.
Inspections During Work
Schedule required inspections at key stages: after roof deck preparation, during installation, and upon completion. Inspections verify proper installation, flashing details, and compliance with approved plans.
Final Inspection & Documentation
After completion, schedule a final inspection. Once passed, you'll receive documentation showing your roof meets Seattle's building standards. Keep this for property records and future sales.
Compliance Tips
- ✓ Verify contractor licensing - Ensure your roofing contractor holds current Washington State contractor registration and Seattle business license
- ✓ Check material approvals - Some roofing materials require specific approval for Seattle's climate conditions
- ✓ Document everything - Keep records of permits, inspections, and manufacturer warranties for future reference
- ✓ Consider weather timing - Schedule roofing work during Seattle's drier months to avoid weather-related delays
- ✓ Review warranty requirements - Some manufacturer warranties require permitted, inspected installations
- ✓ Plan for inspections - Coordinate inspection timing with your contractor to avoid work stoppages
Special Considerations
HOA Rules
Many Seattle neighborhoods have Homeowners Associations with specific roofing requirements. HOAs may restrict certain materials, colors, or installation methods.
Always check HOA covenants before starting work. Some associations require architectural review committee approval in addition to city permits. Failure to comply can result in fines or required modifications.
Zoning
Seattle's zoning codes affect roofing projects through:
- Height restrictions that limit roof modifications
- Setback requirements for roof overhangs
- Green building standards for commercial properties
- Stormwater management requirements for large roof areas
- Solar access regulations in some zones
Historic Properties
Seattle has numerous historic districts and landmark properties with strict preservation requirements. In these areas:

- Additional documentation and approvals are typically required
