How much does a roof replacement cost in Wisconsin?
The Vanderflip Home Cost Index puts Wisconsin roof replacement at about $8,700 to $16,700 in 2026. Its midpoint is $11,900 in southern Wisconsin and $12,300 in the northern Northwoods.[4]
That is one published range, not a quote for your house.
Treat it as a frame for comparing bids.
| Figure | What it covers | Geography | Source | Date |
|---|---|---|---|---|
| $8,700 to $16,700 | Roof replacement range | Wisconsin | Vanderflip Home Cost Index[4] | 2026 |
| $11,900 midpoint | Roof replacement | Southern Wisconsin | Vanderflip Home Cost Index[4] | 2026 |
| $12,300 midpoint | Roof replacement | Northern Northwoods | Vanderflip Home Cost Index[4] | 2026 |
Other pages quote different ranges because they assume different home sizes, materials and scopes. Compare scope first, then price.
Factors that set a Wisconsin roof's price
A headline price usually assumes a single-layer tear-off with little or no decking repair. Anything beyond that shows up as an add-on.
That's why two quotes for the same house can land far apart.
| Cost driver | How it changes a quote | What to ask |
|---|---|---|
| Roof size | Measured roof area sets material and labor, not the home's square footage | "What roof measurement did you use?" |
| Tear-off layers | A second layer adds labor and disposal | "How many layers are you removing, and is disposal included?" |
| Pitch and access | Steep slopes, valleys, dormers and tight access add labor | "Did you account for valleys, dormers and attached structures?" |
| Ice and water protection | Extra membrane adds material and labor | "How many feet up from the eave does it go?" |
| Material | Asphalt, impact-resistant shingles and metal price differently | "Which product line and warranty is priced?" |
| Permit | Fees and who pulls the permit differ by city | "Is the permit fee in the quote, and who handles inspections?" |
Ice and water protection
Wisconsin winters make ice dams a real failure point. Membrane along eaves, valleys and penetrations matters.
A quote that lists it on its own line is easier to compare than one that says only "underlayment."
Decking and tear-off surprises
Rotted sheathing is hard to judge until the old shingles are off.
Get a written price per sheet for decking replacement before work starts. That way a change order won't catch you off guard.
Pro tip
Get the decking price per sheet in writing before work starts, so a change order is easy to check.
Snow loads and roof cost in Wisconsin
Wisconsin sets roof snow loads by zone: Zone 1 is 40 psf in the north and Zone 2 is 30 psf in the south.[1] The code requires roofs to be designed and built to carry the listed minimum loads.[5]
Side by side
Wisconsin roof snow load zones
Zone 1 (north)
- 40 psf minimum load
Zone 2 (south)
- 30 psf minimum load
For a re-roof, the zone matters most if the crew finds deficient decking or framing.
No cited source puts a dollar figure on the zone, so ask your roofer how a repair would be priced.
Counties clear of the line in Zone 1 include Ashland, Bayfield, Douglas, Marathon, Oneida and Vilas. Zone 2 counties include Dane, Milwaukee, Waukesha, Racine, Kenosha and La Crosse.[1]
These counties sit on the zone line: Adams, Brown, Buffalo, Clark, Door, Dunn, Eau Claire, Jackson, Juneau, Oconto, Outagamie, Pepin, Pierce, Portage, Shawano, St. Croix, Trempealeau, Waupaca, Waushara, Winnebago and Wood.[1]
Ask the county or municipal building inspector which zone your lot is in. The full list is on the snow load by county page.
Re-roof permit fees by city
It depends on the city. Estimated re-roof permit costs are $223.20 in Milwaukee and $157.00 in Madison.[4]
A quote that includes permitting in one city may leave it out in another.
Here is how some of the larger cities answer, checked October 2026:[2]
| City | Roof permit | Notes |
|---|---|---|
| Madison | Yes | Madison permits |
| Eau Claire | Yes | Inspections |
| La Crosse | Yes | La Crosse permits |
| Fond du Lac | Yes | Fond du Lac permits |
| Brookfield | Yes | Brookfield permits |
| Superior | Yes | Superior permits |
| Green Bay | No | Green Bay permits |
| Waukesha | No | Waukesha permits |
| Racine, Oshkosh, Franklin, Neenah | Depends | Check with the city |
| Milwaukee, Kenosha, Appleton | Not confirmed | Check with the city: Milwaukee, Kenosha, Appleton |
Every city, with its page link, is on the permits by city page.
The city or building inspector has the final word on your job.
Who can pull the permit
DSPS does not list a state license for roofing.[3] A contractor who pulls a building permit for a one- or two-family dwelling needs the Dwelling Contractor and Dwelling Contractor Qualifier credentials (SPS 305.31).[3]
Verify both with the DSPS credential lookup, and read more on the Dwelling Contractor license page.
Line items for a roofing quote
Ask for at least three itemized estimates and compare them line by line, not by total.
A good proposal states each of these in writing:
- The number of existing shingle layers, the tear-off method and disposal
- Ice and water membrane coverage, and how far up from the eave it runs
- Underlayment type, flashing plan and ridge ventilation
- A price per sheet for decking replacement
- Who pulls the permit, the fee, and who handles the inspection
- The contractor's Dwelling Contractor and Qualifier credential numbers
- Warranty terms, including whether labor is covered as long as the shingles
Photograph your attic and any trouble spots before work begins. That record helps if a leak or hidden repair comes up later.
