Metal Roofing in New Glarus Woods, Wisconsin — Lifetime Interlock® Aluminum Shingles Installed Locally

Interlock's four-way interlocking aluminum panels shed snow and ice efficiently because the smooth surface prevents water from pooling under ice. With about 89 cm of snow falling annually in your area and roughly 84 freeze-thaw cycles per year, the lightweight design—the Slate profile installs at just 0.41 lb/sq ft—won't stress your structure even under peak snow load. The panels remain stable through repeated freezing and thawing without cracking, splitting, or losing their interlocking seal, unlike asphalt or wood shakes that deteriorate under those exact conditions.

No. Aluminum's crystalline structure actually strengthens under repeated freeze-thaw stress—the opposite of what happens to asphalt, wood, and concrete tile. New Glarus Woods experiences about 84 freeze-thaw days annually, and that cycling is precisely where asphalt begins to crack and wood shakes split. Interlock's 3105-H24 aluminum alloy (ASTM B209) is engineered to expand and contract without fatigue. The panels won't curl, crack, or lose their interlocking grip across those 84 cycles every year.

Aluminum cannot rust because it contains no iron—the element that causes rust in steel roofing. Instead, aluminum develops a protective oxide layer that seals itself when scratched, a process called passivation. Your region receives about 781 mm of rain annually, and while moisture is present year-round, it cannot corrode aluminum. Interlock panels are coated with Alunar 70% PVDF fluorocarbon finish on both sides, warranted 30 years against chalking and fading (ASTM D4214/D2244), giving you corrosion protection that steel simply cannot match.

The four-way interlocking panel system is warranted to resist wind speeds up to 120 mph when installed to specification. New Glarus Woods experiences typical gusts reaching about 104 km/h (65 mph) annually, well within that capacity. The interlocking seams lock panels on all four sides, distributing wind load across the entire roof rather than relying on fasteners alone. That design is especially valuable during winter ice storms, where wind and ice weight combine to stress a roof's weakest points—the seams—which Interlock's design eliminates.

Many insurers offer discounts for UL 2218 Class 4 impact-rated roofing, and Interlock's panels carry that highest available rating. The warranty even covers hail perforation up to 1.5 inches. Ask your agent whether Class 4 aluminum qualifies for a discount in your policy—many companies recognize the dramatically reduced hail-claim risk compared to asphalt or composition shingles. Combined with Wisconsin's annual rainfall of about 781 mm and your region's exposure to severe weather, that impact rating may translate to savings that pay down the roof's cost over time.

The Guardian is a lifetime limited, non-prorated material warranty for the original owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance—all the failure modes that plague asphalt, wood, and tile roofs. It's transferable once to the next owner for 50 years from completion. That means you own a roof that doesn't degrade like conventional materials do across 84 annual freeze-thaw cycles or decades of Wisconsin weather. No pro-rating means a failure at year 25 is covered as fully as one at year 5.

No structural reinforcement is needed. Interlock's Slate profile weighs just 0.41 lb/sq ft, and the Mediterranean Tile—despite its traditional appearance—weighs about 0.59 lb/sq ft, making it roughly 96% lighter than concrete or clay tile. Most existing roof structures can support that weight without modification, and the panels install directly over your current roof in many cases, saving thousands on tearoff costs. That lightweight advantage is especially valuable in New Glarus Woods, where 89 cm of snow annually would compound the structural strain if you chose real slate or tile.

Aluminum requires virtually no maintenance. Unlike asphalt shingles, which crack and curl as they age, or wood shakes, which split and rot under Wisconsin's 84 annual freeze-thaw cycles, Interlock panels self-seal and don't degrade from weather exposure. The Alunar 70% PVDF coating is warranted 30 years against chalking and fading—meaning the roof maintains color and finish without sealant reapplication, power washing, or preventive treatments. Your only task is occasional gutter cleaning, the same as any roof.

Yes. Interlock's energy-efficient colors achieve initial solar reflectance up to 0.55 and thermal emissivity of 0.84, reflecting solar heat rather than absorbing it like dark asphalt absorbs Wisconsin's roughly 3089 annual sunshine hours. That reflection means less heat transfer into your attic on sunny days, reducing air-conditioning load during summer and fall. Metal roofing is Cool Roof Rating Council rated, and while Wisconsin winters are cold (mean 9.1°C annually), summer cooling savings combined with the 30-year coating warranty make the energy benefit measurable over the roof's life.

Yes—approximately 95% of Interlock's aluminum is recyclable at end of life, whereas asphalt shingles end up in landfills by the ton. A typical 2,000 sq ft asphalt tear-off generates 8+ tons of waste; Interlock's lightweight design and multi-decade lifespan mean far fewer replacements and zero landfill contribution. The aluminum is roofing-grade 3105-H24 alloy (ASTM B209), manufactured since 1998 in Delta, BC, and installed worldwide from salt-air coasts to Antarctica, proving its durability eliminates the tear-off-and-replace cycle that makes asphalt unsustainable over time.

Yes. New Glarus Woods 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.
