80 Tornado Warnings in 20 Years: Dane County's Storm Record
Between 2005 and 2025, the National Weather Service issued 80 tornado warnings for Dane County, and 21 tornadoes touched down in the county over that same stretch. The strongest of them came in 2005, the same year the weather service counted 16 tornadoes across southern Wisconsin in a single outbreak on August 18.
Tornadoes get the headlines, but they’re only part of what Dane County roofs deal with. Straight-line wind lifts shingle tabs and peels back ridge caps. Hail bruises shingles and knocks the granules loose, and that kind of damage usually can’t be seen from the ground. Then winter brings months of snow load and ice building up at the eaves.
The April 14, 2026 Hailstorm Hit Dane County
On April 14, 2026, supercells developed over southern Wisconsin, and the National Weather Service reported giant hail over Dane County, with stones up to softball size in parts of the Madison area. Storm reports logged a 4-inch hailstone east of Maple Bluff and repeated reports of baseball-sized hail around Madison that evening.
Hail that size can crack a shingle outright, but plenty of the damage from a storm like this is quieter: bruised mats, lost granules, and dented flashing that can start leaking well after the storm has passed. If your roof wasn’t inspected after April 14, it’s worth having someone look before the next winter sets in.
Two Reasons Dane County Homeowners Call a Roofing Contractor
Most calls we get come down to one of two situations.
The first is storm damage. After hail or high wind, the question is whether the damage is real and whether it’s covered. We start with a free inspection, document what we find, and if a claim makes sense, we work it with your insurance company from the adjuster’s visit to the final invoice. Sometimes the honest answer is a small roof repair, and we’ll tell you that too.
The second is age. Curling shingles, bare spots, a leak around a chimney or vent: these show up on roofs that are simply reaching the end of their life. A free inspection tells you whether you’re looking at a repair that buys a few more years or a full roof replacement, and what each one involves.
A County of Newer Homes and Established Neighborhoods
Dane County has about 265,000 housing units, and roughly 58% of them are owner-occupied. The median home was built in 1986, and more homes went up in the 2000s than in any other decade. That mix shows up on the roof: many houses from the 2000s may still have their original shingles and are getting close to a first replacement, while homes in the county’s older neighborhoods can already be on their second or third roof.
The median value of an owner-occupied home in the county is about $366,000. On a house worth that much, a roof replacement is a big decision, and it deserves a real inspection and a straight answer before any money changes hands.
One Roofing Code Countywide, Many Permit Offices
Wisconsin’s Uniform Dwelling Code is the statewide code for one- and two-family homes, and a reroof on a home it regulates has to meet its roofing rules. Its ice-dam rule, SPS 321.28(4), covers shingled roofs with a slope of 4:12 or less over heated living space or an attached garage. On those roofs, the ice-dam protection has to run at least 30 inches up the slope from the roof edge and at least 12 inches past the inside face of the exterior wall. A contractor who pulls the building permit also needs a Dwelling Contractor certification from the state.
Permits are a different story. Reroof permits are handled locally, and the details change from one community to the next: some use in-house inspectors, some contract inspections to outside firms, and a few add local rules that go beyond the state code. We check what applies to your address and pull the permit as part of the job.
Why That One Construction Co. Is the Right Dane County Roofer
We hold every inspection to a 50% rule. Insurance companies treat a roof as a total loss when half of it is damaged, and we use that same line for our own recommendation. If a storm hit one side of your house and the rest of the roof is sound, we’ll recommend a repair, even though a replacement would be a bigger job for us.
About 80% of our work is insurance claims, and we keep dedicated claims staff in-house. Working with insurance companies is what they do every day. They meet adjusters, push back on estimates that leave damage out, and stay with a claim through reinspections. Most claims close in around 30 days. Contested ones take longer, and we’ll tell you that at the start.
When the work’s done, the property should look the way it did before we arrived. Garage doors get boarded before tear-off, landscaping gets covered, and we run magnets over the yard and driveway for nails. Making sure it looks like we weren’t there is the standard on every job.
