Serving All of WisconsinA Wisconsin Roof Is Its Own Discipline
Wisconsin roofs live through freeze-thaw cycling, heavy snow load, spring ice dams, and a severe-storm season that runs from summer hail into fall wind. A roof that was fine in a milder climate cuts corners here fast -- thin ice-and-water shield coverage, weak ventilation, and under-rated fasteners are what turn into leaks and premature failure after a few Wisconsin winters.
Dukes Roofing has built its whole approach around that reality since 1996. We spec ice-dam protection to state code, balance attic ventilation for our winters, and install GAF systems that carry real manufacturer warranties. And because we field separate crews in Northeast and Southeast Wisconsin, the team that shows up already knows the housing stock and the weather in your part of the state.
Find Roofing Near You -- Northeast or Southeast Wisconsin
Dukes covers Wisconsin through two regional teams, each with its own local crews and phone line. Choose your region to see the cities we serve and the roofing realities specific to your area.
Milwaukee Metro & The Lakeshore
Waukesha County's established suburbs, the Milwaukee metro, and the Lake Michigan shoreline down to the Illinois line -- freeze-thaw, lake-driven storms, and a deep mix of historic and modern housing stock.
Green Bay & The Fox Valley
The Green Bay area and the Fox Cities corridor -- heavy Northeast Wisconsin snow, Fox Valley hail seasons, and everything from lakeside homes to fast-growing suburban builds.
The Standards We Never Cut Corners On
Wisconsin's Uniform Dwelling Code sets real requirements for how a roof has to be built here. A lot of them are exactly where a cheap job gets cheap. Here is what the code actually says -- and what we hold every Dukes installation to.
Two Layers, Then Full Tear-Off
Wisconsin caps a roof at two layers of shingles. If yours already has two, code requires a complete tear-off before a new roof -- no shingling over a third time. We tear off and inspect the deck either way.
Licensed Wisconsin Dwelling Contractor
The state requires roofers to hold DSPS Dwelling Contractor and Dwelling Contractor Qualifier credentials to pull permits on homes. Dukes is a licensed, insured Wisconsin Dwelling Contractor -- ask any roofer to prove the same.
Ice-Dam Protection At The Eaves
On low-slope sections over heated space, code (SPS 321.28) requires ice-dam protection running at least 30 inches up-slope from the edge. In Wisconsin winters this is the detail that stops leaks -- we install it, not skip it.
Rated For Snow Load & Wind
Wisconsin roofs must be built for the state's snow loads and wind speeds, with corrosion-resistant fasteners and proper flashing at valleys and chimneys. We spec wind-rated systems and balanced ventilation as standard.
Local municipalities may add their own permit thresholds -- our regional crews handle the permitting for your city.
Three Seasons Of Stress On Every Wisconsin Roof
Wherever you are in the state, a Wisconsin roof takes a beating from the same three directions. Our spec sheets are built around them.
Snow Load & Ice Dams
Heavy accumulation and freeze-thaw cycling drive ice dams that force water back up under shingles. Ice-and-water shield and balanced ventilation are the fix -- and Wisconsin code requires the shield on low slopes.
Hail & Straight-Line Wind
Summer brings severe storms statewide -- the May 2025 system dropped 2-inch-plus hail across Southeast Wisconsin, and the Fox Valley sees its own hail seasons. Class 4 impact-resistant shingles can qualify for insurance discounts.
Freeze-Thaw Cycling
Wisconsin's constant winter freeze-thaw works fasteners loose, cracks aging shingles, and finds every weak flashing detail. It is why cut-corner roofs fail here years earlier than they should.

Common Questions From Wisconsin Homeowners
Have a question we did not cover? Call the line for your region -- N.E. Wisconsin (920) 739-0728 or S.E. Wisconsin (262) 781-9150.
We serve Wisconsin through two regional teams. Our Southeast Wisconsin crews cover the Milwaukee metro, Waukesha County, and the Lake Michigan shoreline including Kenosha and Racine. Our Northeast Wisconsin crews cover the Green Bay area and the Fox Valley including Appleton and Oshkosh. If you are not sure which region you fall in, call either line and we will point you to the right team.
Wisconsin code allows a maximum of two layers of shingles. If your roof already has two layers, the old roofing has to come off completely before a new roof goes on -- you cannot shingle over a third time. Even when a second layer is technically allowed, we recommend a full tear-off so we can inspect and repair the deck and install a complete, warrantied system.
Most Wisconsin municipalities require a re-roofing permit, and the state requires roofers to hold DSPS Dwelling Contractor and Dwelling Contractor Qualifier credentials to pull permits on homes. Dukes is a licensed, insured Wisconsin Dwelling Contractor, and our regional crews handle the permitting for your city as part of the job. It is always fair to ask any roofer to show the same credentials.
Late spring through fall is the sweet spot, with early fall often ideal -- shingles seal best in moderate temperatures, and you get ahead of winter. That said, we roof year-round in Wisconsin using cold-weather techniques when needed. The bigger factor is not waiting: an aging or storm-damaged roof exposed through a Wisconsin winter can turn a simple job into interior damage.
Ice dams form when heat escaping into the attic melts snow on the upper roof, which then refreezes at the colder eaves and forces water back up under the shingles. Wisconsin code requires ice-and-water shield on low-slope sections over heated space, running at least 30 inches up from the edge. We install that shield and balance attic ventilation and insulation -- the real long-term fix -- rather than just chipping ice every winter.
Local, and permanent. Dukes Roofing has been family owned and operated since 1996 with dedicated crews in both Northeast and Southeast Wisconsin. After a big storm you will see out-of-state outfits show up, collect, and leave. We are not one of them -- our 5-year workmanship warranty only means something because we are still here to stand behind it.
