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

Aluminum metal roofing sheds snow faster than asphalt because its smooth, slick surface doesn't grip like shingles do, reducing ice-dam risk during Farmington's typical 84 freeze-thaw cycles per year. The lightweight panels—the Shingle at just 0.41 lb/sq ft—mean your home's structure doesn't bear the accumulated weight that slate or concrete tile would. Four-way interlocking keeps panels secure even when snow shifts, and the aluminum oxide layer remains intact through repeated thaw-refrost cycles. Over 105 cm of annual snow, that durability matters season after season.

Aluminum cannot rust because it contains no iron—the metal that oxidizes into rust. Instead, aluminum develops a microscopic oxide layer that actually protects it. When scratched, this layer self-heals automatically, sealing the bare metal underneath. Our roofing-grade 3105-H24 and 3003-H24 alloy (ASTM B209) is paired with Alunar 70% PVDF fluorocarbon coating on both sides, warranted for 30 years against chalking and fading. In Farmington, where you get about 726 mm of rain annually, that dual-layer defense keeps the roof looking and performing like new for decades.

Yes—the Interlock Mediterranean Tile profile weighs about 0.59 lb/sq ft, roughly 96% lighter than concrete or clay tile, so no structural reinforcement is needed. You can install it directly over most existing roofs, saving thousands in framing work. Concrete tile alone can demand substantial engineering upgrades. Because aluminum is so light, installation is faster and labor costs stay lower. The trade-off is zero: you get the architectural appeal of traditional tile without the engineering headache or the structural load that would otherwise require costly bracing.

Interlock's four-way interlocking aluminum panels are warranted to resist sustained winds up to 120 mph and handle the gusts that regularly reach 101 km/h in Farmington. Each panel locks to its neighbors on all four sides, distributing wind load across the entire roof rather than relying on fasteners alone. The system earned ICC-ES evaluation ESR-1790 for wind performance under IBC/IRC codes. During spring and fall storms—when wind gusts spike—that mechanical interlock is far more reliable than nail-and-shingle or even single-lock standing-seam designs.

Interlock metal roofing carries a UL 2218 Class 4 impact rating—the highest available—and the warranty covers perforation from hailstones up to 1.5 inches. Class 4 impact performance often qualifies homeowners for insurance discounts because the roof proves it won't fail under the hail events that routinely damage asphalt. That non-combustible aluminum also qualifies for Class A fire rating, another underwriter incentive. Check with your insurer, but many Farmington homeowners see rate reductions that offset roofing costs over time.

In Farmington's ~3113 annual sunshine hours, reflective roofing colors save real money on cooling. energy-efficient Interlock colors deliver thermal emissivity of 0.84 and solar reflectance up to 0.55—meaning they bounce heat away rather than absorbing it like dark asphalt does. Cool Roof Rating Council verification confirms the performance. Lighter colors won't eliminate AC costs, but they reduce peak roof temperature by 20–30°F on sunny days, lowering cooling loads especially during summer. Paired with aluminum's conductivity, you're looking at measurable energy savings across the roof's 50-year lifecycle.

The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner—covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance with no depreciation over time. It transfers once to the next owner, who receives 50 years of coverage from completion. Because aluminum doesn't rot, split, or curl, and the Alunar coating is warranted 30 years against fading, you're insured across the entire lifecycle. That one-time transfer also boosts resale appeal; buyers see a genuine 50-year safety net, not a prorated promise that weakens year by year.

Aluminum metal roofing requires virtually no maintenance—no algae treatments, no missing-shingle repairs, no cracked-tile replacements. Asphalt shingles degrade under Farmington's 84 annual freeze-thaw cycles and need patching every few years; wood shakes split and curl; concrete tile cracks. Interlock aluminum simply sits there, shedding 726 mm of rain and 105 cm of snow without degrading. The Alunar coating resists chalking and fading across 30 years, so color stays true. Your only task is the occasional gutter clean—same as any roof—making this the last-roof-you-buy in terms of active upkeep.

Yes, Interlock's lightweight panels install directly over most existing roofs without tear-off—saving landfill waste and labor costs. Installation timeline depends on roof size and complexity, but the interlock system's modular design speeds fastening compared to standing-seam or shingle nail-down. Our local installer, Interlock Metal Roofing, has served the region since 2001 and can assess your specific roof during a consultation. By installing over existing material rather than stripping it, you avoid weeks of debris management and reduce total project time, letting you move from estimate to protection in days rather than months.

Aluminum roofing is approximately 95% recyclable—at end of life, the panels go to metal recycling facilities and become new products indefinitely. Asphalt shingles, by contrast, are shredded and buried in landfills by the million tons yearly, creating a one-way waste stream. Over 50 years, a typical Farmington home might replace asphalt four times; Interlock installs once and never enters a landfill. The manufacturing footprint per year of roof life is far smaller. If you care about waste reduction and circular material use, aluminum eliminates the tear-off-and-dump cycle that defines asphalt maintenance.

Yes. Farmington 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.
