Janesville Premium Roofing provides professional roof leak repair in Janesville, WI for residential and commercial properties across south central Wisconsin. A leak repair in Janesville is unregulated work on every house in the city, whatever year it went up. SPS 320.05 puts repairs and maintenance outside the Uniform Dwelling Code entirely. That is not a loophole somebody found. It is the deliberate design of the code.
Which means the written scope is the only thing standing between you and whatever the last crew felt like doing. There is no permit, no inspection and no state standard for a repair. We have opened flashings on houses in the Old Fourth Ward and found four generations of roofing cement stacked up, each layer applied because it was faster than pulling shingles. Cement is not a repair. It is a way to postpone one.
Our repair reports name the failure instead of describing the symptom. Backed-out fasteners on a wind-lifted course. A step flashing lapped the wrong way where the roof meets a wall. A closed valley cut through the shingle above the metal. A plumbing boot whose rubber collar split at year twelve, which is what rubber collars do. Each one has a different fix and a different price.
We also date the repair against the house. On a post-1980 roof we bring the patch back to SPS 321.28, because the roof it is joining was built to that section and mixing standards inside one assembly is how the next leak starts. On a pre-1980 roof we match what is actually up there, which is frequently lighter than the modern rule. Mixed standards inside one roof plane always fail at the seam between them.
Honest math: a repair is worth doing when the rest of the roof still has real life left. If shingles are curling at the corners across three slopes, granules are stacking in the gutter and the field feels soft underfoot, a six-hundred-dollar patch buys you one season and costs you a season of interior damage. We will say that on the ladder, not afterward.
Everything gets photographed, marked on a slope diagram, and left with you. If the roof gets replaced in four years the next crew knows exactly where the deck was cut and what went back in. On a pre-code house that single sheet of paper is worth more than the repair itself, because nothing else on record describes what is under there. We suggest keeping it with the deed and the furnace paperwork.
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 roof leak repair
The difference between roof leak repair that lasts and roof leak repair 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.

If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
