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

Aluminum's smooth, interlocking surface sheds snow efficiently while its thermal properties help prevent ice dams—a critical advantage in a region averaging 105 cm of snow annually and experiencing about 84 freeze-thaw days per year. The panels' four-way interlock and light weight (the Slate profile at 0.41 lb/sq ft) mean no structural strain even under accumulated snow load. Unlike asphalt, which can deteriorate rapidly through repeated freeze-thaw damage, aluminum's self-healing oxide layer remains intact through countless winter cycles, maintaining its seal and performance year after year.

Maple Grove experiences roughly 84 freeze-thaw cycles annually—each one weakens asphalt shingles, causes wood to split, and stresses coatings. Roofing-grade 3105-H24 aluminum contains no iron, so it cannot rust or rot, and its oxide layer self-heals when scratched, making it fundamentally immune to freeze-thaw cracking and deterioration. The Alunar 70% PVDF fluorocarbon coating, warranted 30 years against chalking and fading per ASTM standards, protects the substrate without relying on sealants that shrink and fail in temperature swings. This combination means your roof's structural and aesthetic integrity survives decades of Wisconsin winters.

Maple Grove's typical gusts reach 99 km/h, and the four-way interlocking Interlock panels are warranted to resist sustained winds up to 120 mph (193 km/h)—far exceeding local conditions. The interlocking seams mean each panel is mechanically secured to its neighbors, eliminating the vulnerability of individual asphalt shingles that catch wind and lift. This design has proven itself from coastal British Columbia (where salt air adds corrosive stress) to Antarctic research stations. For a region averaging daily-max winds around 20 km/h with occasional stronger gusts, this redundancy delivers genuine peace of mind against wind-driven rain infiltration and blow-off.

Interlock metal roofing carries a UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty even covers perforation from hailstones up to 1.5 inches. This proven resilience has led many insurers to offer premium discounts for metal roofing. In Wisconsin's 739 mm average annual rainfall, hail events pose real risk; asphalt shingles fail from impacts that merely dent aluminum. Ask your insurance agent about discounts once you install—the combination of Class 4 impact performance and a lifetime limited, non-prorated material warranty often qualifies for meaningful savings that reduce your true cost of ownership.

Aluminum cannot rust because it contains no iron; instead, it forms a self-healing oxide layer that protects the metal beneath. In Wisconsin's 105 cm of annual snowfall and 739 mm of rain, this immunity to rust eliminates the corrosion pathway that steel panels face and that salt-treated roads accelerate. The roofing-grade 3105-H24 and 3003-H24 aluminum alloy per ASTM B209 specs, combined with Alunar 70% PVDF fluorocarbon coating on both sides, means moisture never compromises the substrate. Over a 50-year lifespan (the transferable warranty term), you avoid the rust stains, structural weakening, and eventual perforation that steel or untreated metals experience in cold, wet climates.

Yes. Interlock's Mediterranean Tile profile weighs roughly 0.59 lb/sq ft—about 96% lighter than concrete or clay tile—so no structural reinforcement is required. Many Wisconsin homes can accommodate metal tile directly over existing asphalt without any modifications. This matters because concrete tile weighs 8–10 lbs per sq ft, requiring expensive roof framing upgrades. With Maple Grove's 105 cm average annual snow load, the light weight of metal tile means the snow burden itself becomes the primary load concern, not the roofing material. You get the authentic visual appeal of traditional tile with zero structural cost—a practical advantage that asphalt, slate, or wood shake installations cannot offer.

Metal requires virtually no maintenance. Unlike asphalt shingles (which shed granules, curl, and crack after 15–20 years), metal roofing sheds water by design and resists deterioration. Unlike wood shakes (which split, rot, and harbor moss in wet climates), aluminum cannot rot or decay. Gutters should be cleared seasonally—the same duty you'd perform for any roof. No caulking, no sealant reapplication, no algae treatments. The Alunar fluorocarbon coating, with a 30-year warranty against chalking and fading, means the roof's appearance and water-shedding ability remain consistent through Maple Grove's 84 annual freeze-thaw cycles and 739 mm of rain without intervention. One roof, one installation, one lifetime.

Interlock metal roofing costs more initially but becomes the last roof you install. Asphalt shingles cost $100–150 per sq ft installed but last 15–20 years in Wisconsin's 84 annual freeze-thaw cycles—requiring two to three replacements over 50 years, plus removal and landfill fees. Metal costs $200–250 per sq ft but lasts 50+ years with a lifetime limited, non-prorated Guardian Warranty covering the original owner and one 50-year transfer to the next owner. Over 50 years, accounting for inflation, labor, and waste disposal, metal typically costs 30–50% less per year of service. Add no maintenance costs, potential insurance discounts from UL 2218 Class 4 impact rating, and energy savings from energy-efficient reflectance, and the case strengthens further.

Yes. Interlock's lightweight profiles—Slate at 0.41 lb/sq ft, Shake at 0.58, Tile at 0.59—install directly over most existing roofs without structural reinforcement. Your installer removes the old roof only if structural damage exists, if flashing or substrate is compromised, or if local code requires it. Installing over asphalt speeds the job, avoids tear-off costs and landfill fees, and retains the removed shingles' insulative value. Underlayment and closure strips ensure water-tightness. The four-way interlocking panels are fastened to the deck below, creating a unified system. Typical installation takes 2–5 days depending on roof size and pitch. This process, combined with no structural work needed, makes conversion from asphalt to metal accessible to most Wisconsin homeowners without major disruption or cost.

Aluminum is roughly 95% recyclable at end of life, while asphalt shingles are single-use waste destined for landfills. Maple Grove's 105 cm of annual snowfall and 739 mm of rain mean asphalt roofs fail after 15–20 years, requiring repeated tear-offs and disposal. A metal roof lasts 50+ years without removal, eliminating the cycle of landfill waste. When an Interlock roof eventually reaches end-of-life, the aluminum can be melted and reformed into new roofing, gutters, siding, or aircraft components—indefinite reuse. The Alunar fluorocarbon coating reduces maintenance frequency to near-zero, further lowering the roof's environmental footprint. Choosing metal means choosing one roof per generation instead of three asphalt roofs per century.

Yes. Maple Grove averages about 105 cm of snow, 739 mm of rain, roughly 84 freeze–thaw days a year, with peak wind gusts near 99 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.
