Permit Process
Project Assessment
Have a licensed roofing contractor assess your project to determine if permits are needed. They can identify structural considerations, material requirements, and code compliance issues specific to Troy's building standards.
Application Submission
Submit a permit application to Troy's building department, typically including project details, contractor information, material specifications, and structural calculations if required. Commercial projects may need additional documentation.
Plan Review
The building department reviews submitted plans for code compliance, structural integrity, and material specifications. This process ensures the roofing work meets Michigan's snow load requirements and wind resistance standards.
Permit Issuance
Once approved, the permit is issued with any specific conditions or requirements. Fees are typically based on project valuation and must be paid before work begins.
Inspections
Schedule required inspections at key stages: after roof deck preparation, during installation, and upon completion. Inspections verify proper installation, flashing details, ventilation, and code compliance.
Final Approval
After passing final inspection, the building department issues a certificate of completion or final approval, which is important for insurance purposes and future property transactions.
Compliance Tips

- ✓ Document everything - Keep copies of permits, inspection reports, contractor licenses, and material warranties for future reference and insurance purposes.
- ✓ Schedule inspections early - Book required inspections well in advance to avoid project delays, especially during peak roofing seasons in spring and fall.
- ✓ Consider weather timing - Plan roofing projects around Michigan's weather patterns, accounting for potential delays due to rain, snow, or extreme temperatures.
