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

Metal roofs shed snow and ice more effectively than asphalt because the smooth, hard surface prevents water from refreezing at the eaves—the core cause of ice dams. Interlock's four-way interlocking aluminum panels are warranted to resist wind gusts up to 120 mph, which easily handles Ashton's typical maximum gusts near 104 km/h even when snow load adds lateral stress. The panels' light weight (the Cedar Shingle profile installs at just 0.41 lb/sq ft) means snow never overloads your structure the way slate or concrete tile would. Optional snow guards can be installed if you prefer controlled snow release rather than full shedding.

Yes—aluminum is inherently immune to freeze-thaw damage because it contains no iron and cannot rust or rot. Ashton experiences about 84 freeze-thaw days per year, which destroys asphalt (allowing water penetration and expansion) and wood shakes (splitting and curling). Interlock panels are manufactured from roofing-grade 3105-H24 / 3003-H24 aluminum alloy (ASTM B209), and their Alunar 70% PVDF fluorocarbon coating is applied to both sides, protecting against the moisture cycling that degrades traditional materials. After 25+ years of installations from coastal salt-air climates to Antarctic research stations, this design has proven durable in extreme wet-cold environments.

Aluminum cannot rust because it contains no iron—the element that oxidizes and corrodes. Ashton receives about 781 mm of rain annually, creating persistent moisture conditions that would cause steel roofing to rust within years, but Interlock's aluminum develops a self-healing oxide layer that actually protects the metal underneath. Even if the coating is scratched, the aluminum's natural chemistry repairs the exposed surface. The Alunar 70% PVDF fluorocarbon finish applied to both panel sides adds 30 years of warranty coverage against chalking and fading, but the core material remains corrosion-proof regardless of rain, snow, or freeze cycles.

Interlock offers a lifetime limited, non-prorated material warranty for the original owner—the only roof warranty that doesn't diminish over time. It covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance. The warranty is one-time transferable to the next owner, providing 50 years of coverage from completion, which protects your home's resale appeal. The coating itself carries a 30-year warranty against fading and chalking (measured by ASTM D4214 / D2244 standards). With Ashton's 84 annual freeze-thaw days putting stress on traditional roofs, a non-prorated lifetime warranty means your investment is protected against the exact failure modes that plague asphalt and wood in this climate.

Interlock panels carry 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 rating means the panels can withstand repeated impacts from 2-inch steel balls dropped from 20 feet, simulating severe hail. Many insurers offer discounts on premiums for Class 4-rated roofs because claims are rare. Wisconsin hail events can be intense, and while Ashton's climate data doesn't highlight hail as routine, the impact resistance becomes valuable insurance against sudden damage—plus it eliminates the risk of punctures that would allow water infiltration during the 89 cm of snow melt each spring.

Interlock panels are warranted to resist sustained wind speeds up to 120 mph (193 km/h) when installed to specification, which far exceeds Ashton's recorded maximum gusts near 104 km/h. The four-way interlocking design means each panel locks to its neighbors on all sides—the wind doesn't catch a loose edge. This engineering is verified under ICC-ES evaluation report ESR-1790 (the current IBC/IRC standard, reissued in 2025). Unlike asphalt shingles, which can lift and tear from wind, or standing-seam steel, which relies on exposed fasteners, Interlock's mechanical interlock distributes wind load across the entire roof plane, protecting against Wisconsin's spring and fall gust patterns.

Yes—Interlock's aluminum is extraordinarily light. The Mediterranean Tile profile, for example, weighs about 0.59 lb/sq ft, making it roughly 96% lighter than concrete or clay tile. This weight advantage means most homes can support a new Interlock roof directly over an existing asphalt roof without structural reinforcement, saving thousands in framing upgrades. Ashton experiences about 120 cm of snow annually, but because Interlock is so light, the snow load stress on your frame actually decreases compared to the original roof. Compare that to slate or genuine tile, which require engineering consultation and sometimes steel support beams. Interlock delivers architectural beauty with minimal structural demand.

Interlock metal roofs require virtually no maintenance—no granule replacement, no moss treatment, no wood sealing. Asphalt shingles degrade under Ashton's 781 mm annual rainfall and 84 freeze-thaw days, demanding gutter cleaning and frequent inspections. Wood shakes split and curl from freeze-thaw cycling and must be chemically treated to prevent rot. Interlock's aluminum and fluorocarbon coating are inert; rain washes them clean. The CALGreen standard has verified Interlock for reduced maintenance requirements. Over a 50-year lifespan, asphalt requires re-roofing twice; wood requires constant care; Interlock requires occasional gutter cleaning and a hose-down if debris accumulates. No repairs, no recoating—just a roof that works.

Most residential installations complete in 2–4 days depending on roof complexity and weather. Because Interlock panels are lightweight and four-way interlocking, installation is faster than slate, tile, or standing seam. You can install directly over your existing asphalt roof without tear-off, which saves days and eliminates disposal costs—critical in Ashton's freeze-thaw climate where old asphalt often has ice or moisture trapped underneath. The local Interlock installer has served the region since 2001 and knows Wisconsin weather windows well: spring (after snow melt) and fall (before freeze cycles) are ideal, though installation happens year-round. The installer can discuss your specific timeline and seasonal considerations when you request a site visit.

Interlock aluminum is approximately 95% recyclable, ending the asphalt tear-off-to-landfill cycle that generates millions of tons of waste annually. When your roof eventually reaches end-of-life, the panels are returned to aluminum mills and become new products—automotive parts, beverage cans, building components. Asphalt shingles are landfilled for decades because they're difficult to recycle. With Ashton's heavy rainfall (781 mm per year) and seasonal snowmelt, water infiltration into landfilled asphalt leaches binders and oils into soil. Interlock's non-combustible aluminum (Class A fire rating available) and durable coating mean one installation lasts your lifetime and into the next owner's—eliminating the environmental cost of repeated replacements. Manufactured since 1998 in Delta, BC, and installed globally, the material's low-impact profile is proven at scale.

Yes. Ashton averages about 89 cm of snow, 781 mm of rain, roughly 84 freeze–thaw days a year, with peak wind gusts near 104 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.
