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

Yes—aluminum actually thrives in freeze-thaw conditions. Unlike asphalt shingles that crack and curl through about 81 freeze-thaw days per year in Waukesha County, aluminum expands and contracts uniformly without degrading. The 3105-H24 alloy won't split or become brittle. The self-healing oxide layer resists the salt and moisture that accelerate decay in wood or composite materials. You're looking at a roof that gets tougher with age in your climate, not weaker.

The four-way interlocking system locks panels together so snow and ice move as one mass—no individual panels lift or separate under the roughly 88 cm of annual snow. The design meets ICC-ES ESR-1790 load specifications for Wisconsin snow loads. Snow guards are available to control edge release. Because Interlock weighs only 0.41 to 0.59 lb/sq ft depending on profile, the total roof load stays light enough that your existing structure handles it without reinforcement, even with accumulated snow.

Aluminum cannot rust because it contains no iron—the element that oxidizes into rust. Instead, a microscopic aluminum oxide layer forms naturally and heals itself when scratched, sealing out moisture. In Lake Five's humid climate with about 775 mm of annual rain, this is a real advantage over steel roofing, which requires constant coating maintenance to prevent rust. Add the Alunar 70% PVDF fluorocarbon finish applied to both sides of every panel, warranted 30 years against fading and chalking, and you've got corrosion protection that simply outlasts asphalt.

No. Interlock panels are warranted to resist sustained winds up to 120 mph, and your typical spring gusts around Lake Five reach about 100 km/h (62 mph). The four-way interlocking system locks each panel to its neighbors on all sides, so wind has to lift the whole roof at once—it can't peel panels one by one like it can with shingles. When installed to spec by a qualified contractor, this design has performed from coastal salt-air zones to Antarctica. Your seasonal gusts are well within the design envelope.

Interlock is rated UL 2218 Class 4, the highest impact rating available, and the warranty covers perforation from hailstones up to 1.5 inches. Class 4 rating often qualifies you for insurance discounts—contact your agent with the UL listing number. In Wisconsin's climate, with about 3074 sunshine hours annually, hail events are less frequent than spring wind, but when they occur, aluminum's hardness and flexibility absorb impact better than asphalt, which cracks and loses granules. You're protected both by the material and by the warranty.

Metal roofing costs more upfront than asphalt, but it's the last roof you'll buy. Asphalt needs replacement every 15–20 years; Interlock comes with a lifetime limited, non-prorated material warranty for the original owner, transferable for 50 years to the next owner. Over 50 years, the math favors metal—you avoid three asphalt replacements, tear-off costs to landfill, and rising labor rates. Interlock's light weight (0.41–0.59 lb/sq ft) also installs over most existing roofs, saving one tear-off cost right there.

energy-efficient Interlock colors have thermal emissivity of 0.84 and solar reflectance up to 0.55, meaning they bounce heat away instead of absorbing it like asphalt. In a climate with about 3074 annual sunshine hours, this reduces air-conditioning load in summer. The Cool Roof Rating Council has rated these finishes. You won't see dramatic savings in Lake Five's cool climate, but the reflective properties help moderate attic temperatures year-round, reduce thermal stress on the coating, and contribute to the 30-year warranty against fading.

Minimal. Interlock is verified CALGreen-compliant for reduced maintenance. Unlike asphalt, you don't replace shingles or clear granules; unlike wood shakes, you don't treat for rot or insects; unlike concrete tile, you don't power-wash algae. With about 775 mm of rain annually in Waukesha County, gutters and downspouts do the work. A professional inspection every few years catches anything missed, but the coating is warranted 30 years against chalking and fading. Most owners find metal roofing is the maintenance they don't have to do.

Installation happens in phases: inspection and prep, flashing installation, panel layout and fastening, ridge and edge trim, gutter connection, and final walkthrough. If installing over an existing roof, your old layer stays put—no tear-off, no disposal cost—and the new panels fasten directly to the existing deck. Timelines vary with weather and roof complexity, but a residential project typically takes 1–3 weeks. Interlock has served the region since 2001 and knows Lake Five's building codes, snow loads, and seasonal weather windows.

Aluminum is about 95% recyclable at end of life—it retains value as scrap metal. Interlock ends the asphalt cycle: traditional shingles tear off and go to landfill every 15–20 years, a pattern that repeats for decades. A metal roof installed once means no tear-offs, no landfill disposal, and when eventually recycled, the material enters the aluminum stream again as raw stock. In a region receiving 775 mm of rain and 88 cm of snow annually, durability that lasts a lifetime rather than decades is the most sustainable choice you can make.

Yes. Lake Five averages about 88 cm of snow, 775 mm of rain, roughly 81 freeze–thaw days a year, with peak wind gusts near 100 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.
