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

Yes—Interlock's four-way interlocking aluminum panels are engineered to shed snow and resist ice damming in climates like Edgewood's, where you'll see about 88 cm of snow annually. The lightweight design (the Slate profile weighs just 0.41 lb/sq ft) means snow doesn't compress into ice the way it does on heavier asphalt, and the smooth interlocked seams prevent water from pooling during the 81 freeze-thaw cycles your region experiences each year. Optional snow guards are available if you prefer controlled shedding. The panels expand and contract with temperature swings without cracking or curling—aluminum's natural flexibility handles Wisconsin winters reliably.

Aluminum actually thrives in freeze-thaw conditions because it expands and contracts uniformly without degrading. Your area experiences roughly 81 freeze-thaw days per year, which would cause wood shakes to split and asphalt to crack—but aluminum panels remain intact through those stress cycles. The material itself contains no organic components that absorb water and rupture when frozen. Interlock's roofing-grade 3105-H24 aluminum alloy (ASTM B209) and Alunar 70% PVDF coating (warranted 30 years against cracking under ASTM D4214) are specifically rated for exactly this kind of climatic wear. The Guardian lifetime limited warranty covers cracking, so freeze-thaw durability is not a future worry.

Aluminum cannot rust because it contains no iron—rust only forms when iron oxidizes. What aluminum develops instead is a transparent, self-healing oxide layer that actually protects the material beneath. In Edgewood's humid climate with about 775 mm of annual rainfall, that oxide layer continuously repairs itself when scratched or weathered, meaning the roof doesn't degrade over decades the way steel roofing does. Steel roofs require paint or coatings to prevent rust; aluminum's protection is intrinsic. Interlock adds further durability with a Alunar 70% PVDF fluorocarbon finish applied to both sides of every panel, giving you a 30-year warranty against corrosion in addition to the material's inherent non-rusting properties.

Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. Edgewood's typical gusts reach about 100 km/h, well within that range. The interlocking design means each panel is mechanically secured to its neighbors, creating a unified system that resists uplift and lateral forces far better than overlapped asphalt shingles, which can peel during seasonal wind events. This isn't just marketing—the engineering is validated by ICC-ES evaluation report ESR-1790 (reissued 2025 for IBC/IRC compliance). During the spring and autumn storms your region experiences, that interlocked grip gives you confidence your roof will stay in place.

Interlock aluminum roofing carries a UL 2218 Class 4 impact rating—the highest available—and the warranty even covers perforation from hailstones up to 1.5 inches. Class 4 is the benchmark insurers use when evaluating impact resistance, and many homeowners in hail-prone regions see premium reductions when they install a Class 4-rated roof. Edgewood's climate doesn't feature extreme hail events, but the durability is built in. Contact your insurer with the UL 2218 Class 4 rating; some carriers offer discounts because the roof's impact resistance reduces claim likelihood. The material's light weight also means impact forces dissipate differently than on heavy slate or tile, giving you genuine protection without the structural burden.

The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner—meaning no gradual reduction in coverage over time. It covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance for as long as you own the home. The warranty is transferable once, giving the next owner 50 years from completion date, which significantly boosts resale appeal in Edgewood's market. The Alunar coating alone carries a separate 30-year warranty against chalking and fading (measured per ASTM standards), so even the finish is protected well beyond the typical asphalt roof's 15-20 year lifespan. Paired with aluminum's inherent resistance to freeze-thaw cycles and the 88 cm of annual snow your region receives, this warranty reflects a product engineered to last generations, not decades.

Interlock metal roofing needs virtually no maintenance—no annual inspections for cracked or curled shingles, no wood treatments, no algae removal. Asphalt roofs in Edgewood's climate (775 mm rain, 88 cm snow, 81 freeze-thaw cycles per year) degrade rapidly from UV exposure during 3074 sunshine hours annually, requiring frequent repairs. Wood shakes split during freeze-thaw cycles and rot in moisture. Aluminum simply weathers in place without degradation. Leaves may collect in gutters, as they do with any roof, but the roofing surface itself doesn't require pressure washing, re-coating, or seasonal repair. The CALGreen certification recognizes this reduced-maintenance durability. Over a 50-year lifespan, that elimination of maintenance visits and repairs—plus the absence of tear-off and landfill costs—compounds into genuine savings.

Yes. Interlock aluminum roofing is extraordinarily light—the Mediterranean Tile profile weighs just 0.59 lb/sq ft, making it roughly 96% lighter than concrete or clay tile. This means no structural reinforcement is required, and the roof can install directly over your existing shingles in most cases, eliminating expensive tear-off and disposal costs. Edgewood homeowners often face the choice: tear off asphalt (landfill waste), reinforce the structure to support traditional tile, or choose aluminum that installs cleanly over existing material. The light weight also reduces stress during Edgewood's heavy snow events—about 88 cm per year—since the roof itself doesn't add burden to your framing. The ICC-ES evaluation (ESR-1790) confirms installation over existing roofs is code-compliant.

Interlock's energy-efficient colors are rated with thermal emissivity of 0.84 and solar reflectance up to 0.55 (Aged Copper Penny), meaning they reflect heat rather than absorb it—unlike asphalt, which stores solar energy. In Edgewood, where you enjoy about 3074 annual sunshine hours, that reflectance reduces cooling demand on hot days, lowering air conditioning costs over summer months. The Cool Roof Rating Council certification validates this performance. During your region's 81 freeze-thaw cycles, that same reflectivity prevents excessive thermal cycling that degrades asphalt shingles. The energy savings aren't dramatic in a Wisconsin climate, but they're real and measurable—particularly in spring and early fall when cooling is occasional but effective.

Interlock Metal Roofing has served the Edgewood and greater Kenosha County region since 2001, bringing over two decades of local installation experience to your project. A local installer means faster response times, familiarity with Wisconsin's specific climate challenges (88 cm of snow, 81 freeze-thaw days, gusts to 100 km/h), and accountability within the community. They understand the drainage patterns, building codes, and seasonal constraints unique to your area—details that matter when timing an installation around Edgewood's weather. You're working with professionals who've installed hundreds of Interlock roofs through Wisconsin winters and can answer site-specific questions about your home's orientation, existing structure, and local wind exposure.

Yes. Edgewood 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.
