Janesville Premium Roofing provides professional metal roofing in Janesville, WI for residential and commercial properties across south central Wisconsin. Metal is the one roof covering where the manufacturer's printed instructions become the rule, on both sides of the 1980 line. SPS 321.28 sends other roof coverings to the manufacturer's installation instructions or a nationally recognized standard, and then stops offering specifics of its own.
That is more consequential than it sounds. With asphalt the code hands you fastener counts and head laps. With standing seam it hands you a document written by the panel maker: clip spacing, panel gauge, substrate requirements, closure details at ridge and eave. Whoever installs it is agreeing to that document, and most quotes never acknowledge that it exists. We have watched panels installed at clip spacings the maker never published, on houses where nobody checked.
Ours attaches it. We name the panel profile, the gauge, the clip type and spacing, and the underlayment the manufacturer requires beneath it, which is usually a high-temperature synthetic rather than felt. On a post-1980 Janesville house that paperwork is the enforceable standard. On a pre-1980 house it is the only standard in the room. If we cannot produce the instruction sheet for the panel we are proposing, you should not buy the roof from us.
Whether you can go over the existing shingles is decided by the same section. No new covering over a base that is water-soaked or deteriorated, none over wood shake, slate, clay, cement or asbestos-cement tile, and none where two or more applications are already down. We check that before anything else, because it changes the bid more than the panel choice does. That check takes ten minutes and saves arguments later.
Here is where we talk people out of things. On a pre-1980 house with wavy board sheathing, exposed-fastener corrugated panel is a mistake. The panel telegraphs every cupped board, the fastener gaskets sit at odd angles and start weeping around year eight, and you end up with a roof that looks worse at ten years than the asphalt it replaced. We have taken enough of them back off to be firm about it.
Standing seam over a flattened or re-decked surface is a different product entirely, with concealed clips that let the panel move and no exposed rubber to age out. It runs roughly two to three times an asphalt reroof. On a house you intend to keep twenty-five years that arithmetic works. On a five-year hold it plainly does not. We will run both numbers and let the years you plan to stay decide it.
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 metal roofing
The difference between metal roofing that lasts and metal 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.
The standards behind metal roofing
Quality here is not a matter of opinion — it is written down. The metal roofing work we do in Janesville follows published industry standards: NRCA publishes the Roofing Manual, the industry's reference for details and slope minimums, and Asphalt Roofing Manufacturers Association sets the shingle application and ventilation guidance the warranties reference. If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
