Permit Process
Project Assessment
Begin by evaluating your roofing project scope. Determine if structural changes, material changes, or complete replacement is planned. This assessment helps identify which permits may be needed and what documentation to prepare.
Document Preparation
Gather necessary documents including property surveys, site plans, roofing material specifications, manufacturer installation guidelines, and contractor information. For commercial projects, architectural drawings and engineering calculations may be required.
Application Submission
Submit permit applications to the appropriate Cornelius or Washington County building department. Applications typically require project details, contractor licensing information, and payment of applicable fees based on project valuation.
Plan Review
Building officials review submitted plans for code compliance. This process ensures roofing materials, installation methods, and structural elements meet Oregon building code requirements for wind resistance, fire ratings, and durability.
Permit Issuance
Once approved, permits are issued with specific conditions and inspection requirements. Keep permits visible at the job site and ensure all work follows approved plans and specifications.
Inspections
Schedule required inspections at key project milestones. Typical roofing inspections include decking preparation, underlayment installation, final material installation, and ventilation systems. All inspections must pass before work is considered complete.
Compliance Tips
- ✓ Verify contractor licensing - Ensure roofing contractors hold valid Oregon Construction Contractors Board (CCB) licenses and appropriate bonding.
- ✓ Check material certifications - Use roofing materials with proper UL listings, fire ratings, and wind resistance certifications for Oregon climate conditions.
- ✓ Maintain proper documentation - Keep all permits, inspection reports, and manufacturer warranties organized for future reference and potential resale.
- ✓ Schedule inspections promptly - Don't wait until project completion to schedule required inspections; coordinate with your contractor throughout the process.
- ✓ Consider energy efficiency - Oregon building codes increasingly emphasize energy efficiency; discuss insulation and ventilation upgrades during roofing projects.
- ✓ Review insurance requirements - Some insurance policies require permits for covered repairs; confirm requirements with your provider before starting work.
Special Considerations
HOA Rules
Many Cornelius neighborhoods have Homeowners Associations with architectural review committees. HOA approval is often required before obtaining city permits.
HOAs may restrict roofing material types, colors, and installation methods. Some associations require specific shingle brands or colors to maintain neighborhood aesthetics. Always check HOA covenants before planning roofing work.

- Height restrictions may limit roof pitch changes
- Setback requirements affect roof overhangs and eaves
- Commercial properties have additional fire rating requirements
- Multi-family buildings require specific egress and safety considerations
- Environmental zones may have stormwater management requirements
