Janesville Premium Roofing provides professional gutters & downspouts in Janesville, WI for residential and commercial properties across south central Wisconsin. The Uniform Dwelling Code has essentially nothing to say about gutters. SPS 321.28 requires that roofs be designed and constructed to assure drainage of water and that fasteners be corrosion resistant, and that is where it stops, on both sides of the 1980 line.
That is worth knowing because it explains the market. No inspector checks a gutter on any house in this city whatever year it went up, so gutter work is the first line trimmed out of a competing bid and the last thing anybody documents. Undersized, under-hung and under-sloped gutter is the most common defect we find, and it is nobody's violation. It is the one part of a roof system where nobody is watching at all.
So we spec it in writing. Six-inch seamless aluminum K-style in .032 gauge on most Janesville houses instead of the five-inch standard, hidden hangers screwed into the fascia at 24 inches on center rather than driven spikes, and 3x4 downspouts in place of 2x3. The larger outlet is the single change that matters most on a steep roof. Water leaves a roof faster than most people expect, and the outlet is the bottleneck.
Six-inch is not always right. On a small ranch with a shallow pitch and short runs, five-inch handles the water perfectly well and costs less, and we will quote it that way and explain why. Selling the bigger profile to a house that does not need it is easy, and it is also exactly why people stop trusting roofers. Right-sizing costs us margin and it keeps us working here.
The part that fails first around here is not the gutter at all. It is the discharge. A downspout dumping at the foundation of a 1920s Janesville house with a stone or early block basement wall does far more damage than a little overflow ever will, and extensions or a buried drain line are cheap next to a wet basement. Fix the discharge before you spend anything on the gutter above it.
Gutter guards get an honest answer too. Under a mature silver maple they earn their keep. On an open lot with nothing overhanging the roof they mostly reduce the flow rate and give you a reason to stop looking. We install several types and we will tell you when the right answer is to skip them and clean twice a year. Nobody sells a maintenance habit, which is part of why guards sell so well.
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 gutters & downspouts
The difference between gutters & downspouts that lasts and gutters & downspouts 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.
