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

Aluminum panels shed snow effectively because they're smooth and slippery — ice and wet snow don't bond to the surface the way they do to asphalt. Wilson averages about 107 cm of snow annually and around 86 freeze-thaw days per year, which causes asphalt to crack and curl. Interlock's four-way interlocking panels resist wind uplift even when loaded with snow, and aluminum's non-porous oxide layer won't degrade from repeated freezing and thawing. Snow guards are available if you want to control snow slide, giving you full control over your roof's behavior in winter.

No — aluminum cannot rust because it contains no iron. Instead, it forms a microscopic oxide layer that self-heals when scratched, protecting the material underneath. Wisconsin's average of 795 mm of annual rainfall and variable humidity won't corrode aluminum the way they corrode steel. Interlock uses roofing-grade 3105-H24 and 3003-H24 aluminum alloy, coated on both sides with Alunar 70% PVDF fluorocarbon finish (30-year warranty against fading). This dual-sided protection is especially important in damp climates — the underside resists moisture exposure as thoroughly as the top.

Freeze-thaw cycling — Wilson experiences about 86 freeze-thaw days yearly — cracks asphalt shingles, splits wood shake, and shatters concrete tile because these materials absorb moisture, expand when frozen, and contract when thawed. Aluminum is non-porous and doesn't absorb water, so it won't crack or deteriorate from repeated temperature swings. The material's flexibility also absorbs expansion and contraction without damage. Over a roof's 30–50 year service life, this immunity to freeze-thaw becomes the dominant advantage: other materials fail and need replacement; Interlock keeps working.

Yes — Interlock is warranted to resist wind speeds up to 120 mph when installed to specification. Sheboygan County's typical daily-maximum winds are about 18 km/h, with gusts reaching 93 km/h, well within that rating. The four-way interlocking aluminum panels lock together mechanically, so high wind can't lift or separate them. The ICC-ES evaluation report (ESR-1790) confirms the system meets IBC/IRC building codes for wind resistance. For a region where spring and fall bring variable wind, this structural rigidity eliminates the risk of blow-offs and leaks that plague traditional shingles.

Interlock achieves UL 2218 Class 4 impact rating — the highest classification available — and the Guardian Warranty covers perforation even from hailstones up to 1.5 inches. Class 4 rated roofing often qualifies for homeowner insurance discounts because hail damage claims drop dramatically. Wisconsin's average 107 cm annual snow suggests variable spring weather with hail risk. Because aluminum panels don't dent, crack, or lose integrity under impact the way asphalt or wood do, your insurance company views the roof as lower-risk. Contact your insurer about discounts; many offer 10–25% reductions for Class 4 impact-rated systems.

No reinforcement needed — Interlock's lightweight aluminum is the key advantage. The Slate profile installs at just 0.41 lb/sq ft, the Mediterranean Tile at 0.59 lb/sq ft — about 96% lighter than concrete or clay tile. Your home's structure already carries the weight of existing asphalt shingles, plus snow (Wilson averages 107 cm annually). Interlock metal weighs far less than snow load alone. The system installs directly over most existing roofs, so your framing carries less total load after installation, not more. This eliminates $5,000–$15,000+ in reinforcement costs that traditional tile would demand.

Virtually none — Interlock requires no more upkeep than asphalt shingles and far less than wood or clay tile. The non-porous aluminum resists moss, algae, and mildew growth even in Wisconsin's 795 mm annual rainfall. Wood shake splits and curls, requiring annual inspection and repair. Asphalt granules erode into gutters, necessitating frequent cleaning. Aluminum panels don't degrade, crack, or shed debris. The CALGreen-verified system is rated for reduced maintenance. A simple gutter cleaning once per year is sufficient. Over 50 years, you'll spend hours maintaining an asphalt roof; Interlock demands almost no intervention.

The Guardian Warranty is a non-prorated, lifetime limited material warranty for the original owner — covering rust, rot, splitting, cracking, curling, and loss of impact resistance. It transfers once to the next owner, who receives 50 years of coverage from completion. No other roof offers this structure: asphalt warranties are 20–30 years and heavily prorated; wood and tile warranties cap out at 30–50 years and degrade each year. If you plan to stay in your Wilson home long-term, you'll never replace this roof. If you sell, the warranty becomes a genuine selling point — the new owner inherits half a century of peace of mind.

Yes — energy-efficient Interlock colors reflect solar heat instead of absorbing it. The Aged Copper Penny profile has initial solar reflectance up to 0.55 and thermal emissivity of 0.84, meaning it rejects heat that dark asphalt absorbs and re-radiates into your home. Wisconsin receives about 3,061 sunshine hours annually. On sunny 25–30°C summer days, a reflective metal roof reduces attic temperature by 10–20°C compared to asphalt, cutting air-conditioning load and costs. The Cool Roof Rating Council rating confirms the performance. You won't feel the savings on every day, but over a summer season — and over decades — reflective coating pays for itself in energy alone.

Installation typically takes 2–5 days depending on roof size and complexity. A major advantage: Interlock installs directly over existing asphalt or wood shingles — no tear-off required. Because the system weighs only 0.41–0.59 lb/sq ft (compared to 2–4 lb/sq ft for asphalt), your home's structure handles the addition. You avoid debris, labor, and landfill costs associated with tearing off the old roof. The solid deck plus underlayment makes the system acoustically quiet in rain — indistinguishable from asphalt. Interlock Metal Roofing has served the Sheboygan County region since 2001 and can walk you through the timeline and process for your specific home.

Yes. Wilson averages about 107 cm of snow, 795 mm of rain, roughly 86 freeze–thaw days a year, with peak wind gusts near 93 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.
