Initial Consultation
Start by discussing your roofing project with a licensed contractor familiar with Dennison's building codes. They can help determine if permits are needed and what documentation will be required.

Submit a permit application to the local building department. This typically includes project details, contractor information, property details, and plans showing the scope of work.
Plan Review
Building officials review your application and plans to ensure compliance with local codes, zoning regulations, and structural requirements. This process may involve multiple departments.
Permit Issuance
Once approved, you'll receive the permit and can begin work. The permit must be displayed at the job site and inspections will be scheduled at key project milestones.
Inspections
Required inspections typically include: roof deck preparation, underlayment installation, final roofing installation, and sometimes intermediate inspections for complex projects.

Special Considerations
HOA Rules
If your property is part of a Homeowners Association, additional approvals may be required beyond city permits. HOAs often have architectural review committees that must approve roofing materials, colors, and installation methods.
Check your HOA covenants before starting any roofing work, as they may have stricter requirements than city codes regarding material types, colors, or installation timelines.
Zoning
Zoning regulations may affect roofing projects, particularly for commercial properties or multi-family buildings. Considerations include:
- Height restrictions and setbacks
- Drainage requirements affecting neighboring properties
- Commercial roofing material requirements
- Fire separation requirements for attached structures
Verify zoning compliance before finalizing your roofing plans.
Historic Properties
Properties in historic districts or designated historic homes may face additional restrictions. Historic preservation guidelines often require specific materials, installation methods, or approval processes.
For historic properties in Dennison or Goodhue County, consult with preservation authorities early in your planning process to understand any special requirements.
