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

Yes—aluminum's crystalline structure actually thrives through freeze-thaw stress. Addison experiences roughly 84 freeze-thaw days per year, yet 3105-H24 aluminum alloy (ASTM B209) expands and contracts without the fatigue that degrades asphalt, wood, or ceramic. The Alunar 70% PVDF coating bonds directly to the metal and moves with it; the oxide layer never splits or peels. Over 25+ years of installations from coastal winters to Midwestern temperature swings, this material remains intact where shingles crack and curl.

The four-way interlocking aluminum panels shed snow far more readily than asphalt or wood. Addison receives roughly 96 cm of snow annually, but the low-friction metal surface—especially the Slate and Cedar Shingle profiles—allows snow to slide cleanly before it locks into place and melts. The panels themselves weigh only 0.41 lb/sq ft (Shingle profile), so even with heavy wet snow, your home's structure carries less load than traditional roofing. Optional snow guards can be installed to manage slides on steeper pitches or near walkways.

Aluminum cannot rust because it contains no iron; instead, a transparent oxide layer forms on the surface and self-heals whenever the coating is scratched. This matters enormously in Addison's climate, where 768 mm of annual rainfall and seasonal moisture create the conditions where steel roofing develops rust stains within years. The Alunar 70% PVDF finish (applied to both sides) adds 30-year protection against salt air and acid rain, but even if that coating eventually weathers, the base metal remains stable indefinitely. You'll never replace this roof due to corrosion.

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. In Wisconsin's spring and summer seasons, this resilience often qualifies homeowners for premium reductions. File your UL 2218 Class 4 rating with your insurer; many will lower your deductible or offer credits. Even in rare hail events, aluminum's dent-resistance means cosmetic damage is minimal, and structural failure is virtually impossible.

Addison experiences typical daily winds around 19 km/h with gusts reaching 102 km/h, and the four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h) when properly installed. The mechanical interlocks—not fasteners alone—transfer lateral force across the entire roof assembly. This design has proven itself in hurricane zones and along coastal ridges. In the upper Midwest's spring squalls and winter nor'easters, your roof locks down while lighter materials lift and tear.

No structural reinforcement is needed. The Interlock Mediterranean Tile profile, for example, weighs only ~0.59 lb/sq ft—about 96% lighter than concrete or clay tile—and even the heavier Shake profile comes in under 0.58 lb/sq ft. Most existing roofs can support this metal system without any framing upgrades. In fact, Interlock installs directly over your old asphalt shingles in many cases, saving tear-off labor and landfill impact. Your home's structural engineer, if consulted, will confirm: lighter is safer and faster.

Far less than asphalt, wood, or tile. The aluminum panels require no sealant reapplication, no algae treatment, and no gutter cleaning from granule debris—because there is none. Twice yearly, a gentle rinse removes dust and pollen; in salty or industrial zones, a yearly wash preserves the Alunar finish (though it's not required for durability). Addison's 3,086 annual sunshine hours work in your favor—UV exposure actually helps maintain the coating's appearance. Compare this to asphalt shingles' need for algae control and wood shakes' annual inspection, and the difference is clear.

The Guardian Warranty is a non-prorated lifetime limited warranty for the original owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance—essentially every failure mode except physical damage from accidents. For the second owner, the warranty transfers once and lasts 50 years from installation completion. This means a roof installed today will still be covered when your children sell the home. The 30-year coating warranty separately guarantees no chalking or fading per ASTM testing. Few homeowners ever buy another roof after Interlock.

Yes, substantially. Interlock's aluminum panels are roughly 95% recyclable at end-of-life, and the material never degrades into microplastics or leachate in a landfill. By contrast, a typical asphalt roof sheds millions of granules annually and ends up in a waste stream—and then you replace it again in 15-20 years. Over a 50-year ownership, you'll replace asphalt roofing multiple times, each time removing old material to the landfill. Interlock ends that cycle and qualifies as a CALGreen-verified low-maintenance material. Your roof becomes an asset, not recurring waste.

Installation typically takes 2-4 days for a standard residential home, depending on roof size and complexity. One major advantage: in most cases, Interlock installs directly over your existing asphalt shingles—no tear-off, no days of debris, no contractor trucks blocking your driveway. The old roof becomes an extra insulation and moisture barrier. If your existing roof is damaged or severely deteriorated, removal is recommended, but that's your choice. Either way, the metal panels secure with clip fasteners (not nails), and the four-way interlock means no leaks and faster installation than traditional roofing.

Yes. Addison averages about 96 cm of snow, 768 mm of rain, roughly 84 freeze–thaw days a year, with peak wind gusts near 102 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.
