Janesville Premium Roofing provides professional wind damage roofing in Janesville, WI for residential and commercial properties across south central Wisconsin. Wind rarely takes a roof that was fastened properly. In Janesville the difference usually comes down to two numbers written into SPS 321.28, and to whether the house sits on the side of the 1980 line where those numbers were legally binding on the installer.
The section calls for at least four fasteners per strip shingle, or two per interlocking shingle, unless the manufacturer specifies otherwise, plus a head lap of at least two inches. It also requires self-sealing shingles to carry a sealant bond of at least 1.5 pounds per 3.75 inches of shingle width at 32 degrees. Those are the specifications a shingle relies on to stay put. None of them are difficult to meet. They are just easy to skip.
Pre-1980 roofs in this city were routinely hung with three nails, and often with those nails driven above the sealing strip where they hold very little. That was perfectly legal, because the code did not reach the house. It is also the most common single reason a 1960s Janesville roof loses courses along the west rake while the neighbor's 1997 roof does not. Nobody was cheating anyone. There was simply no rule to break.
So our wind repairs start at the fastener line rather than at the bare spot. We lift the course above the gap and look at where the nails actually landed. If they sit high, the whole slope is on borrowed time and patching the hole is money spent on a symptom. We will tell you that even when it costs us the small job in front of us.
Field repairs get hand-sealed. In cool weather a replacement shingle will not activate its own sealant strip for weeks, so we set it with dabs of asphalt roof cement at the manufacturer's spacing instead of trusting the sun to do it. Skipping that step is why so many wind patches in this county blow off again inside the first month.
Where a roof is otherwise sound we replace courses and move on. Where the fastening pattern is wrong across whole planes we quote the reroof honestly and let you decide. On a pre-code house that decision belongs entirely to you, because no authority is ever going to force it, and you should at least be making it with the real numbers. The numbers are on the roof and we will show them to you.
Our licensed and insured team brings the right materials and equipment to every job — No. 15 asphalt-impregnated felt underlayment, ASTM D4869 Type I underlayment felt, ring-shank nails set into 1x6 board sheathing, No. 28 gauge open-valley sheet metal, 50-pound roll roofing in closed valleys, step flashing and masonry chimney crickets — and backs the work with a written workmanship warranty. We serve Janesville and nearby communities including Beloit, Edgerton, Milton, Evansville.

Materials, equipment and how we do wind damage roofing
The difference between wind damage roofing that lasts and wind damage roofing that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with No. 15 asphalt-impregnated felt underlayment, ASTM D4869 Type I underlayment felt, ring-shank nails set into 1x6 board sheathing, No. 28 gauge open-valley sheet metal, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Janesville job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in south central Wisconsin means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Janesville Chooses Janesville Premium Roofing
- ✓We pull the assessor's construction year before we price a roof, because June 1, 1980 decides whether the state code governs your reroof or your contract has to.
- ✓Our estimates name specifications rather than adjectives: No. 15 felt or a labeled ASTM D226 Type I synthetic, four fasteners per strip shingle, a two-inch head lap.
- ✓We count existing layers by lifting shingles at the rake and a valley, and the count goes in writing before anything is sent to your insurance carrier.
- ✓We go in the attic on every inspection. Fastener rust, valley staining and packed eaves show on the underside of the sheathing long before they show on top.
