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

Yes—aluminum is built for exactly this. West Bend sees about 84 freeze-thaw days per year, where water enters cracks in asphalt, freezes, expands, and splits the shingle. Aluminum panels don't absorb moisture, so ice can't degrade them from within. The four-way interlocking design keeps water moving off the roof fast. Our coating is warranted 30 years against cracking and splitting—conditions that end asphalt roofs in 15-20 years here.

Interlock's aluminum panels shed snow efficiently because the smooth, low-friction surface lets it slide before compacting into ice. West Bend averages about 105 cm of snow annually. The four-way interlocking design means water runs underneath the panels and exits at the eave, preventing the ice-dam backup that rots asphalt roofs and wood fascia. The Slate, Cedar Shingle, and Shake profiles all handle Wisconsin snow loads without structural reinforcement—they're light enough that no framing upgrades are needed.

Aluminum cannot rust because it contains no iron—the element that oxidizes and stains. Instead, aluminum develops a microscopically thin oxide layer that actually protects the metal underneath; if scratched, it self-heals in air. Your West Bend roof faces about 726 mm of rain and moisture from 84 freeze-thaw days yearly, but aluminum stays intact. Steel roofing, by contrast, rusts through in 20-30 years. Interlock's roofing-grade 3105-H24 aluminum alloy meets ASTM B209 and carries a lifetime limited warranty against rusting.

West Bend's typical gusts reach 101 km/h, and Interlock's four-way interlocking panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. The panels lock together on all four sides—not just the top—so wind pressure cannot lift or separate them. Asphalt shingles, meanwhile, are nailed at two points and fail in sustained gusts above 60 mph. Over 20+ years, that's a real difference in West Bend's storm season.

No structural reinforcement is required. Interlock's aluminum Tile profile installs at roughly 0.59 lb/sq ft—about 96% lighter than concrete or clay tile—and the Slate at just 0.41 lb/sq ft. Most homes can install these profiles directly over an existing asphalt roof without framing upgrades. Your West Bend home already supports the weight; metal roofing simply replaces the shingles on top. This means lower installation costs and faster work compared to a tile roof, which would demand new structural support.

Interlock aluminum 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 is the same standard insurance companies use to offer premium discounts on impact-resistant roofing. In West Bend's climate, where hail can strike 3-4 times per year, that protection matters. Many insurers will reduce your premium 15-25% for Class 4 metal roofing. Check with your agent, but the durability often pays for itself in reduced claims and lower rates over the roof's life.

Yes, if you choose an energy-efficient color. Interlock offers profiles in reflective finishes with solar reflectance up to 0.55 (Aged Copper Penny) and thermal emissivity of 0.84, rated by the Cool Roof Rating Council. These colors reflect heat that asphalt absorbs and re-radiates into your attic. West Bend gets about 3113 sunshine hours per year—enough that summer heat gain matters. energy-efficiency coatings typically cut cooling load by 10-15%, which translates to $100-200 per year savings on air conditioning in a typical home.

Very little. Aluminum doesn't split, crack, curl, or lose granules the way asphalt does over West Bend's 84 freeze-thaw days and 105 cm of annual snow. The Alunar 70% PVDF fluorocarbon finish is warranted 30 years against chalking and fading (ASTM D4214/D2244 measured), so you don't repaint. Twice-yearly gutter cleaning keeps debris out of your drainage, and that's standard for any roof. The lifetime limited warranty covers the material itself—no prorated deductibles—so repairs are minimal and inexpensive if they ever occur.

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. It's one-time transferable, giving the next owner 50 years of coverage from completion—a real selling point if you move. Most asphalt shingles carry 20-30 year warranties with steep prorations after year 10. Because aluminum won't degrade the way organic materials do over West Bend's 84 freeze-thaw cycles and heavy snow loads, Interlock backs the roof for its actual lifespan, not an arbitrary term.
