Permit Requirements in Green Bay
Know when you need a permit to ensure your project is legal and safe
General Rules
In Green Bay, roofing permits are generally required when the work involves structural changes, full tear-offs, or major repairs that affect the roof's load-bearing capacity. Most full roof replacements require a permit regardless of the material being used. The city typically reviews these permits to ensure compliance with the Wisconsin Uniform Building Code and local amendments.
Permits are often required for:
- Complete roof replacements
- Structural modifications, including changes to roof trusses, rafters, or decking
- Installing a different type of roofing material than what currently exists
- Adding skylights, dormers, or roof penetrations
- Work that alters the roof's slope or drainage patterns
When Permits Are Required
Full roof replacements – Whether asphalt shingles, metal, tile, or flat roofing, a complete tear-off and replacement typically requires a permit in Green Bay.
Structural repairs – If decking, rafters, or trusses need replacement or reinforcement, a permit is usually required.
Material changes – Switching from asphalt to metal, or from shingles to tile, often triggers a permit review because of weight load and structural considerations.
New roof installations – Adding a roof to a new structure or an addition always requires a permit as part of the larger building permit process.
Commercial roofing – Commercial and multi-family roofing projects almost always require permits due to fire rating, insulation, and structural requirements under the Wisconsin Commercial Building Code.
Common Exemptions
Minor repairs – Replacing a few shingles or patching a small leak typically does not require a permit, as long as the underlying structure is not affected.
Reroofing with same material – In some cases, overlaying a new layer of asphalt shingles over an existing layer (where allowed by code) may not require a permit, though many local authorities still recommend one.
Routine maintenance – Cleaning gutters, applying sealant around vents, or replacing ridge caps as part of regular upkeep usually does not require a permit.
Note: Even if a permit is not required, all work must still comply with applicable building codes. When in doubt, it's always best to check with the local building department.

Permit Process
Determine if a permit is needed
Review the scope of your roofing project against local requirements. Contact the Green Bay building inspection department or visit their office to discuss your specific project. Having detailed plans or a contractor's scope of work ready will help you get a clear answer.
Prepare your application
Gather the necessary documentation, which typically includes a detailed description of the work, roof plans or diagrams, material specifications, and structural load calculations if relevant. For commercial projects, engineered drawings may be required. Many applications can be submitted online or in person.
Submit the permit application
File your completed application along with any required fees. Fees are generally based on the estimated project value or square footage. Be prepared for a review period where the building department checks your plans against local codes and ordinances.
Schedule inspections
After a permit is issued, inspections are typically required at key stages of the project. Common roofing inspection points include the decking inspection (before new roofing is installed), rough-in inspection for any structural work, and a final inspection upon completion. Your contractor should coordinate these with the building department.
Receive final approval
Once all inspections pass and the work is complete, the building department will issue a final approval or certificate of completion. This document is important for property records and may be required when selling the home or filing insurance claims.
Compliance Tips
- ✓ Hire a licensed contractor – Work with a roofer who is familiar with Green Bay's permit process and building codes. Licensed contractors typically handle permit applications on your behalf and schedule required inspections.
- ✓ Don't skip the permit for cost savings – While it may seem easier to avoid the permit process, unpermitted work can lead to fines, stop-work orders, and complications when selling your property.
- ✓ Keep records of all approvals – Save copies of your permit, inspection reports, and final certificate of completion. These documents are valuable for insurance purposes and future property transactions.
- ✓ Plan for weather delays – Green Bay's climate means roofing season is often limited. Factor in potential permit review times and inspection scheduling when planning your project timeline.
- ✓ Verify contractor insurance and licensing – Ensure your roofing contractor carries proper liability insurance and workers' compensation coverage. This protects you if accidents occur during the project.
- ✓ Ask about energy code compliance – Wisconsin's energy code may require specific insulation values or ventilation standards for new roofing. Make sure your contractor accounts for these requirements in the permit application.
Special Considerations
HOA Rules
If your property is located within a homeowners association (HOA) in Green Bay or the surrounding area, be aware that HOA covenants, conditions, and restrictions (CC&Rs) may have additional requirements beyond city permits. Many HOAs have specific rules about roofing materials, colors, and installation methods. Obtain written HOA approval before applying for your building permit to avoid conflicts or rework later.
Zoning
Green Bay's zoning ordinances may affect your roofing project, particularly regarding height restrictions, setbacks, and stormwater management. If your roof replacement involves structural changes that alter the building's height or shape, a zoning review may be required. Commercial properties should also check for parking or signage impacts if the roof work affects building use. Always verify that your project complies with the applicable zoning district requirements.
Historic Properties
Properties located in Green Bay's historic districts, such as the Astor neighborhood or Broadway Historic District, may face additional permitting requirements. The city's Historic Preservation Commission (HPC) often reviews exterior changes to ensure they are consistent with the district's character. Roofing material choices, colors, and even installation methods may need HPC approval before a building permit can be issued. Work done without this approval could result in fines or a requirement to undo the changes.
