Two Reasons Deerfield Homeowners Call a Roofing Contractor

The first is storm damage. Deerfield has had confirmed hail and wind events in recent years, and after a storm like that, most homeowners are dealing with an insurance claim for the first time. Someone from our team stands on that roof right alongside the adjuster, and if what comes back doesn’t match the damage, we tell you and we tell the insurance company. That starts with a free inspection, whether or not you end up filing anything.

The second is a roof that’s simply worn out. Deerfield’s housing stock is on the newer side for this part of rural Dane County, but “newer” still means twenty, thirty, even forty years old in some cases, and that’s well within a roof’s working life. We’ll walk the roof and tell you honestly whether a roof repair covers it or you’re looking at a full roof replacement. We’re not going to push a bigger job than the one you actually need.

Hail and Wind Damage in Deerfield

Deerfield has two confirmed storm events on record worth knowing about. On June 13, 2022, hail about an inch and a half across, roughly ping-pong-ball size, was reported in the village twice within five minutes, part of a broader hail event that moved through this part of Dane and Jefferson Counties that afternoon. More recently, on the night of April 14, 2026, high winds tore the siding off a barn in Deerfield, scattering pieces on both sides of the road.

Both of those events point to the same thing: this area sees real wind and hail, not just the occasional light shower. Hail that size can bruise shingles and knock granules loose without leaving anything obvious to see from the driveway, and wind strong enough to strip siding off a barn is strong enough to lift or crease roofing material too. If either of those storms came anywhere near your home, a roof-level inspection is the only way to know for sure, and we offer that free.

Village vs. Town: Who Handles Your Deerfield Permit

Depending on which side of the line your home sits on, your roofing permit goes through a different office. The Village of Deerfield contracts its building permits and inspections out to SAFEbuilt, which holds office hours at Village Hall on Wednesdays. The Town of Deerfield handles its own permitting separately, with its own building inspector. It’s a small distinction, but it trips people up, and it’s worth confirming which jurisdiction you’re actually in before you assume the process.

Underneath either path, the same statewide rules apply. Wisconsin’s Uniform Dwelling Code requires ice and water shield on any roof slope of 4:12 or less over heated living space or an attached garage, extending at least 30 inches up-slope from the eave and 12 inches past the interior wall face, and every contractor doing this work has to hold a Dwelling Contractor certification through the state. We handle the permit through whichever office applies to your address, so you’re not the one figuring out which door to knock on.

Why That One Construction Co. Is the Right Deerfield Roofer

We’re a certified ShingleMaster contractor through CertainTeed, one of the largest names in roofing materials. That certification isn’t handed out for free. It means we’ve met a standard for installation quality that most roofing crews haven’t, and it’s why CertainTeed backs our work with warranty coverage that goes beyond what a standard install gets. We also look at a roof as part of a whole system, not a job on its own. Joe built this company after years of building homes from the ground up, so drainage, attic ventilation, and how the flashing ties into the wall behind it all get checked, not just the shingles on top. And when we’re finished, we clean up like we mean it. Plywood on the garage doors before we start, landscaping protected, a magnet pass for nails when the job wraps. Making sure it looks like we weren’t there is the standard, not a nice-to-have.
