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

Aluminum's smooth, hard surface sheds snow more readily than asphalt, reducing ice-dam formation during Shorewood's typical 88 cm annual snowfall and 79 freeze-thaw cycles per year. Interlock's four-way interlocking panels lock snow loads in place rather than allowing creep; snow guards can be added if desired. The material's light weight (Cedar Shingle at 0.41 lb/sq ft) means no structural reinforcement is needed even where snow accumulates, and the non-porous aluminum doesn't absorb meltwater that refreezes in freeze-thaw cycles.

No — aluminum's crystalline structure withstands freeze-thaw cycling indefinitely because it contains no iron and cannot rust or rot. The Alunar fluorocarbon coating on both sides protects the substrate, while the self-healing oxide layer seals microscopic scratches that cold weather might otherwise exploit. Over Shorewood's 79 annual freeze-thaw days and 88 cm of seasonal snowmelt, this immunity to moisture damage is a decisive advantage over wood shakes, asphalt (which cracks when frozen), or steel roofing.

Yes — Interlock roofing is warranted to resist wind speeds up to 120 mph when installed to specification. Shorewood experiences typical gusts around 96 km/h (60 mph), well within that limit. The four-way interlocking panel system locks each piece to its neighbors horizontally and vertically, distributing uplift forces across the entire roof rather than relying on fasteners alone. This panel-to-panel grip, combined with proper fastening to the deck, provides the redundancy needed for coastal and inland storm exposure.

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. Aluminum's density and hardness resist denting better than asphalt or wood, and many insurers recognize Class 4 ratings with premium reductions. In Shorewood's hail-prone spring and early-summer season, this durability may lower your annual costs and eliminate the need for roof replacement after severe storm damage.

Aluminum cannot rust because it contains no iron. Instead, it forms a thin, self-healing oxide layer that seals the surface and actually protects it from further oxidation. When scratched or cut during installation in Shorewood—where annual rainfall reaches 822 mm—this oxide spontaneously reforms within hours. Steel roofing, by contrast, requires protective coatings that eventually fail. For a 25+ year roof life here, aluminum's material immunity to rust eliminates the slow degradation and eventual perforation that shortens steel roofing lifespans.

Metal roofing costs more upfront but lasts 50+ years versus asphalt's 15–20 years, meaning you'll replace asphalt 2–3 times during one aluminum roof's life. Interlock's Guardian Warranty is lifetime limited and non-prorated for the original owner, with one transfer to the next owner for 50 years total—eliminating surprise repair costs. Over 50 years in Shorewood's climate of 822 mm rain, 88 cm snow, and 79 freeze-thaw cycles, the total cost (material + labor + maintenance) per year tilts decisively toward metal, plus you stop the asphalt tear-off-to-landfill cycle.

The Guardian Warranty is lifetime limited for the original owner—non-prorated, meaning no reduction over time—and covers rusting (impossible with aluminum), rotting, splitting, cracking, curling, and loss of impact resistance. It's one-time transferable to the next owner, extending protection for 50 years from completion. The Alunar coating itself is separately warranted 30 years against chalking and fading per ASTM D4214/D2244 standards. In Shorewood's damp climate with 3,128 annual sunshine hours and frequent freeze-thaw stress, this coverage means major repairs or color fading are the builder's responsibility, not yours.

energy-efficient Interlock colors reflect solar heat rather than absorb it, with initial solar reflectance up to 0.55 and thermal emissivity of 0.84. This reduces heat transmission into the attic, lowering cooling demand on hot days. While Shorewood averages a cool 9.4°C year-round and 3,128 sunshine hours annually (less than southern climates), reflective coatings still lower peak summer temperatures and reduce air-conditioning cycles. Cool Roof Rating Council certification confirms this benefit in writing for potential energy rebates or credits.

Minimal maintenance. Unlike wood shakes (which rot and split in Shorewood's 79 annual freeze-thaw cycles), asphalt (which cracks and curls), or ceramic tile (which requires mortar repointing), aluminum roofing is inert and non-porous. It sheds debris naturally, resists moss and algae growth, and requires no sealing, staining, or regular inspection. Gutters need cleaning from 88 cm of annual snowmelt and 822 mm of rain, but the roofing itself is maintenance-free. The Alunar coating warranty covers fading and chalking for 30 years, so color preservation is guaranteed.

Interlock Metal Roofing has served the Milwaukee County region since 2001, delivering the same factory-backed product that's been manufactured in Delta, BC since 1998 and installed from coastal salt-air homes to Antarctic research stations. Local installation ensures proper fastening, panel alignment, and four-way interlocking—critical to achieving the 120 mph wind warranty and Class 4 hail rating. When you call a regional installer familiar with Shorewood's snow, wind gusts near 96 km/h, and freeze-thaw cycling, you get expertise that remote contractors cannot match.

Yes. Shorewood averages about 88 cm of snow, 822 mm of rain, roughly 79 freeze–thaw days a year, with peak wind gusts near 96 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.
