Frequently Asked Questions
Do I need a permit to replace my roof in Wisconsin?
Yes, most Wisconsin municipalities require a roofing permit for full roof replacement. This applies to both tear-off-and-replace jobs and overlay (second layer) installations. Permit fees typically range from $75 to $500. Some cities may not require a permit for minor repairs under 100 square feet, but always check with your local building department.
Can I put new shingles over old ones in Wisconsin?
Wisconsin's Uniform Dwelling Code allows a maximum of two layers of asphalt shingles on residential buildings. If you already have one layer, you can overlay a second layer. If you already have two layers, a complete tear-off is required before installing new shingles. This is a statewide rule and cannot be overridden by local municipalities.
Do I need a licensed contractor to replace my roof in Wisconsin?
Homeowners can replace the roof on their own owner-occupied single-family home without a contractor license. However, the contractor performing the work on any other property must have a Dwelling Contractor Qualifier (DCQ) certification from DSPS. Many municipalities also require roofing contractors to show proof of insurance when pulling the permit.
