Metal Roofing in Kohler, Wisconsin — Lifetime Interlock® Aluminum Shingles Installed Locally

Aluminum's smooth surface naturally sheds snow rather than holding it like asphalt, reducing ice dam formation during Kohler's roughly 84 freeze-thaw days per year. Interlock's four-way interlocking panels remain structurally sound through these cycles because aluminum doesn't become brittle or develop stress fractures as temperatures swing between winter lows and spring warmth. The coating's flexibility—maintained by the Alunar 70% PVDF finish warranted 30 years against degradation—prevents cracking that leads to leaks when freeze-thaw stress occurs.

Your existing framing almost certainly needs no reinforcement. Interlock's Slate profile installs at just 0.41 lb/sq ft—roughly 96% lighter than concrete or clay tile—so it places minimal additional load on walls and foundation. Most homes built to support standard asphalt shingles can accept metal roofing without structural modification. This is especially valuable in Kohler, where installing over your existing roof avoids costly tear-off labor and disposal, letting you transition directly to a system that will outlast multiple asphalt cycles.

Aluminum cannot rust because it contains no iron; rust is the oxidation of iron exposed to moisture and oxygen. Instead, aluminum develops a microscopic oxide layer that actually protects it from corrosion. Remarkably, if this layer is scratched, it self-heals—the aluminum re-oxidizes and seals the damage naturally. With roofing-grade 3105-H24 or 3003-H24 aluminum alloy and a two-sided Alunar fluorocarbon coating, Interlock panels resist Sheboygan County's wet climate (726 mm annual rainfall) and coastal-equivalent salt-air environments indefinitely.

No. Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph when installed to specification. Kohler experiences typical gusts around 101 km/h (about 63 mph)—well below that threshold—so your roof will remain fully secured through seasonal storms and the occasional stronger event. The interlocking design distributes lateral forces across the entire panel assembly rather than relying on fasteners alone, making uplift or panel separation extremely unlikely under Wisconsin conditions.

Interlock's aluminum panels carry a UL 2218 Class 4 impact rating—the highest available—and the Guardian warranty explicitly covers perforation from hailstones up to 1.5 inches. Wisconsin hail events, while less frequent than in Great Plains states, do occur, and this rating provides complete peace of mind. Many insurers recognize the superior impact resistance of metal roofing and may lower your premium; contact your agent with the UL 2218 Class 4 specification to explore potential savings.

Interlock roofs routinely perform for 50+ years or longer. The Guardian warranty provides a lifetime limited material warranty to the original owner—non-prorated, meaning no depreciation schedule—covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It's also transferable to the next owner for 50 years from completion date. This transforms your roof from a routine maintenance expense into effectively the last roof you'll install, eliminating the asphalt replacement cycle that has dominated for decades.

Interlock metal roofing is CALGreen-verified for reduced maintenance. Unlike asphalt shingles, which deteriorate and shed granules, or clay tile, which cracks and requires individual replacement, aluminum panels require no routine maintenance—no re-coating, no sealing, no fungicide application. Kohler's 726 mm annual rainfall naturally cleans the surface. Snow and ice slide off effortlessly. Gutters need the same attention they always have, but the roof itself simply performs year after year with zero scheduled intervention.

energy-efficient Interlock colors achieve initial solar reflectance up to 0.55 and thermal emissivity of 0.84, meaning they reflect far more sun than absorb it—opposite of dark asphalt. With about 3113 sunshine hours annually across Sheboygan County, this reflective advantage compounds month after month, reducing cooling load during warm seasons. Cool Roof Rating Council certification confirms these performance metrics. In winter, you retain interior heat as effectively as any roof material. The net effect is lower energy costs throughout the year compared to asphalt, which absorbs and re-radiates solar heat into your home.

Yes. Interlock aluminum is approximately 95% recyclable and retains that value indefinitely, even at end-of-life. Asphalt shingles, by contrast, are typically torn off and landfilled—in a standard 25-year asphalt replacement cycle, your old roof becomes permanent waste. Aluminum breaks this cycle entirely: when your Interlock roof eventually requires replacement (in 50+ years), the panels retain scrap value and can be reclaimed. The lighter weight also means fewer transportation emissions during installation, and the lack of routine maintenance prevents the chemical runoff associated with wood preservatives and tile sealers.

Choosing a factory-trained local installer ensures proper four-way panel engagement, correct fastening to code-compliant standards, and direct access to service should any issues ever arise. Your warranty is backed by both the manufacturer and a company with deep community roots and a reputation built on repeat customers and referrals.

Yes. Kohler averages about 105 cm of snow, 726 mm of rain, roughly 84 freeze–thaw days a year, with peak wind gusts near 101 km/h. Interlock® aluminum roofing is wind-rated to 193+ km/h (120 mph), UL 2218 Class 4 impact-rated and Class A fire-rated, and its four-way interlocking panels shed snow and resist ice dams and freeze–thaw cracking — all backed by a lifetime limited, transferable warranty.
