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

Interlock's four-way interlocking aluminum panels shed snow and ice effectively because the smooth surface and panel overlap design work together to prevent ice dams—a critical advantage in a region that receives about 98 cm of snow annually. The panels are warranted to resist wind gusts up to 120 mph, so heavy wet snow loading won't compromise the seal. Unlike asphalt, which becomes brittle in freeze-thaw cycles (Yerkes experiences roughly 81 such days per year), aluminum maintains its flexibility and doesn't crack or curl under temperature swings. Optional snow guards can be installed if you want to retain snow for insulation or manage runoff direction on lower-pitched sections.

No—aluminum actually excels in freeze-thaw environments. Unlike asphalt shingles, which become brittle and crack after 81 freeze-thaw cycles annually (Yerkes's typical count), aluminum is ductile and flexes without damage. The 3105-H24 and 3003-H24 roofing-grade alloys specified in ESR-1790 are engineered for this stress. Even when snow melts and refreezes, the metal doesn't degrade; the self-healing oxide layer protects the surface. Meanwhile, the Alunar 70% PVDF coating is warranted 30 years against chalking and fading, so seasonal temperature swings won't compromise your roof's finish or water-shedding ability.

Aluminum cannot rust because it contains no iron—the element that oxidizes and corrodes. What aluminum does is form a protective oxide layer when exposed to air, and this layer actually self-heals when scratched. Yerkes receives about 760 mm of annual rainfall, so moisture is constant, but that won't harm aluminum. The Alunar 70% PVDF fluorocarbon finish (applied to both sides of every panel) provides an extra 30-year warranty against chalking and fading per ASTM D4214. Steel roofing requires ongoing maintenance to prevent rust; aluminum simply doesn't. This corrosion immunity is why Interlock panels have been installed from coastal salt-air homes to Antarctic research stations since 1998.

Metal roofing costs more upfront than asphalt but far less over a lifetime. Asphalt typically lasts 15–20 years and requires tear-off and landfill disposal; Interlock's Guardian Warranty is lifetime limited and non-prorated for the original owner, then transferable for 50 years to the next owner. That means one installation lasts your ownership and often the next owner's. You eliminate tear-off labor and disposal costs, avoid maintenance that asphalt demands (sealing, replacing curled shingles), and never reroof. In a region with 81 annual freeze-thaw cycles, asphalt degrades faster; aluminum doesn't crack or curl. Over 40–50 years, the math strongly favors metal.

No structural reinforcement is needed. Interlock's Mediterranean Tile profile weighs only about 0.59 lb per square foot—roughly 96% lighter than concrete or clay tile—and installs over existing roofs without additional support. The Slate profile weighs approximately 0.41 lb/sq ft. Traditional asphalt shingles run about 2–3 lb/sq ft, so metal is actually lighter or comparable. This light weight also reduces labor and installation timeline. Your home's existing framing, verified by local code compliance (ICC-ES ESR-1790, reissued 2025), can safely support metal panels. This efficiency means no costly structural upgrades, faster installation, and often a retrofit directly over your current roof.

Installation timelines vary with home size and weather, but Interlock Metal Roofing, serving the region since 2001, can provide a site-specific estimate. One key advantage: Interlock panels install directly over most existing roofs because they're so light (0.41–0.59 lb/sq ft depending on profile), eliminating tear-off labor and landfill costs. In Wisconsin's typical weather—about 3,073 annual sunshine hours—scheduling is usually straightforward. Removal is always an option if the existing roof is severely damaged or if you want a fresh start. Your local installer will assess your roof's condition and recommend the best approach for your home and budget.

Yes. Interlock panels are four-way interlocked and warranted to resist wind speeds up to 120 mph when installed to specification. Yerkes experiences typical daily-max winds of about 22 km/h with gusts reaching 97 km/h—well within the roof's capacity. The interlocking design means each panel is mechanically secured to its neighbors and the substrate; wind uplift is distributed across the entire roof rather than concentrated on fasteners. This design also meets ICC-ES evaluation report ESR-1790 (IBC/IRC, reissued 2025). Even in rare severe weather, the panel-to-panel connection and low profile make metal roofing far more wind-resistant than asphalt shingles, which can lift and tear.

Interlock metal roofing earns UL 2218 Class 4 impact rating—the highest available—and the warranty even covers perforation from hailstones up to 1.5 inches. This resilience often qualifies homeowners for insurance discounts; contact your agent with the UL 2218 Class 4 rating and product specs. In Wisconsin's climate, hail risk is lower than in Great Plains states, but when it occurs, Class 4-rated metal outperforms asphalt, composition, and most tile. The aluminum's ductility allows it to absorb impact without cracking or puncturing the way brittle materials do. Combined with the lifetime limited warranty, you have both impact protection and financial peace of mind.

Interlock metal roofing is CALGreen-verified for reduced maintenance and requires far less than asphalt, wood shake, or tile. You won't seal seams, replace curled shingles, or treat for algae and moss. Aluminum doesn't rot, split, or crack in freeze-thaw cycles (Yerkes sees about 81 per year). The Alunar 70% PVDF coating is warranted 30 years against chalking and fading. Periodic inspection and gutter cleaning (same as any roof) are prudent. Unlike asphalt, which degrades visibly after 15–20 years, or wood, which requires ongoing treatment, metal simply performs. This low-maintenance profile appeals to homeowners tired of repair cycles and explains why the Guardian Warranty is transferable—the next owner inherits a roof that doesn't demand constant attention.

energy-efficient Interlock colors reflect more solar heat than asphalt absorbs, lowering cooling costs. The Aged Copper Penny finish, for example, achieves initial solar reflectance up to 0.55 and thermal emissivity of 0.84—both energy-efficiency and Cool Roof Rating Council certified. With Yerkes receiving about 3,073 annual sunshine hours, that reflectance compounds savings over time. Metal also cools faster when the sun sets, reducing the radiant heat that asphalt releases into your attic all night. While Wisconsin winters are long, the energy efficiency means no penalty in cold months; the reflective coating simply performs differently with season. Combined with proper attic ventilation, metal roofing can meaningfully lower summer AC usage.

Yes. Yerkes averages about 98 cm of snow, 760 mm of rain, roughly 81 freeze–thaw days a year, with peak wind gusts near 97 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.
