Permit Process
Project Assessment
Determine the scope of your roofing project and whether it requires permits. For commercial projects, this often involves architectural drawings and engineering calculations. Residential projects may need detailed material specifications and contractor information.
Application Submission
Submit permit applications to the appropriate Mendon building department. Applications typically require project details, contractor licensing information, insurance certificates, and sometimes property surveys or site plans.
Plan Review
Building officials review submitted plans for code compliance. This includes checking structural calculations, material specifications, wind load requirements, and fire ratings. Commercial projects often undergo more extensive review than residential ones.
Permit Issuance
Once approved, permits are issued with specific conditions and inspection requirements. Fees are typically based on project value or square footage. Permits must be posted visibly at the job site throughout construction.
Inspections
Schedule required inspections at key project milestones. Common roofing inspections include: deck inspection before underlayment, underlayment inspection before shingles, and final inspection upon completion. Commercial projects may require additional specialized inspections.
Final Approval
After passing all inspections, the building department issues a certificate of completion or final approval. This document is important for insurance purposes, property transfers, and warranty validation.
Compliance Tips
- ✓ Verify contractor credentials - Ensure your roofing contractor is properly licensed in Michigan and carries adequate insurance for roofing work
- ✓ Check material specifications - Confirm roofing materials meet Michigan's climate requirements for wind resistance, ice dam protection, and thermal performance
- ✓ Document everything - Keep copies of permits, inspection reports, warranties, and contractor agreements for future reference
- ✓ Schedule inspections early - Building departments often have limited inspection availability, so plan inspections well in advance of project milestones
- ✓ Consider weather delays - Michigan's climate can affect roofing schedules; build extra time into your project timeline for weather-related permit extensions
- ✓ Review warranty requirements - Many roofing material warranties require proper permitting and inspection documentation to remain valid
Special Considerations

Many Mendon neighborhoods have Homeowners Associations with architectural review committees. HOA approval is often required before obtaining city permits.
HOAs may have specific requirements for roofing materials, colors, and installation methods that go beyond city codes. Some associations restrict certain roofing types or require uniform appearance throughout the neighborhood.
Zoning
Zoning regulations in Mendon can affect roofing projects, especially for commercial properties. Setback requirements, height restrictions, and accessory structure rules may impact roof design.
Commercial properties may need to consider parking requirements, stormwater management, and accessibility standards that affect roof design and drainage systems.
Historic Properties
Mendon has several historic properties and districts with additional preservation requirements. Historic district properties often face stricter review processes for roofing work.
