Two Reasons Madison Homeowners Call a Roofing Contractor

Most calls come down to one of two situations. The first is storm damage. Hail doesn’t always leave a mark you can see from the ground, and after a bad storm, a homeowner is usually dealing with an insurance claim they’ve never navigated before. We meet the adjuster on-site, handle the estimate, and push back if the claim comes in short. It starts with a free inspection so you know what you’re actually working with before anything gets filed.

The second is a roof that’s simply reached the end of its life. Madison’s homes span everything from century-old bungalows near the isthmus to newer construction on the edges of the city, and a lot of homeowners are making their first roofing decision without knowing what a fair recommendation even looks like. We’ll tell you if a section can be repaired instead of replaced. That’s not the answer that makes us the most money, but it’s the one we give. A free inspection is where that conversation starts too.

The April 2026 Hailstorm That Hit Madison's East Side

On April 14, 2026, Madison’s East Side took a direct hit from one of the largest hail events reported anywhere in Wisconsin that day. The National Weather Service documented roughly two dozen reports of hail two inches or larger in a line running through the city, and one stone near the East Side measured four inches across, the largest confirmed anywhere in the state. Hundreds of cars and homes were damaged. One auto body shop in the Atwood neighborhood alone took in more than 70 vehicles in a single day. The scale of the damage was enough that the Wisconsin Department of Agriculture, Trade and Consumer Protection issued a public warning about storm-chasing contractors moving into the area after the event.

Madison has seen severe weather before this. NWS storm surveys have confirmed tornado touchdowns within city limits, including one on the East Side in October 2017 and an EF1 in the Marquette neighborhood in June 2014. For homes near Lake Mendota or Lake Monona specifically, storms moving in over open water can build speed before they reach the shoreline, which is worth keeping in mind if your property sits close to either lake.

If you haven’t had your roof looked at since the April storm, hail damage is often invisible from the ground. Granule loss, bruised shingles, and bent flashing only show up on a roof-level inspection. That’s the inspection we offer, free, whether or not you end up filing a claim.

Contractor Licensing and Permits in Madison

Madison is one of the few cities in this state where a homeowner can legally pull their own roofing permit and do the work themselves, provided they pass the same inspections a licensed contractor would. It’s a real option here. It’s also exactly why it matters who you hire when you don’t take that route yourself. Wisconsin requires roofing contractors working on one- and two-family homes to hold a Dwelling Contractor certification through the state’s Department of Safety and Professional Services, and after a storm this size, a lot of unlicensed and out-of-town crews show up looking for quick work. We’re certified, we’re local, and we’re not going anywhere once the job is done.

The City of Madison’s Building Inspection Division locally administers the Wisconsin Uniform Dwelling Code, which sets the ice and water shield requirement that applies statewide: on any roof slope of 4:12 or less over heated living space or an attached garage, a self-adhering membrane has to extend at least 30 inches up-slope from the eave and 12 inches past the interior wall face. We handle the permit and the inspections that go with it as part of the job, so it’s one less thing you have to manage yourself.

Why That One Construction Co. Is the Right Madison Roofer

We’re independently owned, with no private equity behind us and no outside investors telling us how to run a job. That matters more than it sounds like it should. A lot of the roofing industry has been bought up by investment firms in the last few years, and a good number of the people on our crew came from companies that got acquired that way. We built this company to run the opposite direction, especially in a market like Madison right now, where a major storm draws in contractors who won’t be around next year.

About 80% of what we do is insurance work, so we’ve been through this process hundreds of times. We have staff whose only job is talking to insurance companies every day. We meet the adjuster on-site, handle the estimate, and if a claim comes in underpaid, we push back on it. You still have to be involved at a few points because some things legally have to come from you, but we carry as much of that process as we can.

And when the job is done, we don’t leave a mess behind. Plywood goes up on the garage doors before we start, landscaping gets protected, and we run a magnet pass for nails when we’re finished. Making sure it looks like we weren’t there is the standard, not a nice-to-have.
