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

Interlock's four-way interlocking aluminum panels shed snow and ice efficiently because the smooth surface creates less friction than asphalt, and the lightweight design (Slate at 0.41 lb/sq ft) means no structural reinforcement is needed despite Lake Church's average 105 cm annual snowfall. The panels are warranted to 120 mph wind speeds, so spring wind-driven snow and ice movement won't compromise the seal. Unlike asphalt or wood shingles, aluminum won't absorb meltwater, preventing the freeze-thaw damage that occurs during your area's typical 84 freeze-thaw cycles per year.

Aluminum has no iron content, so it cannot rust or corrode as moisture cycles through freeze-thaw—a critical advantage in Sheboygan County where you experience about 84 freeze-thaw days annually. The material's oxide layer self-heals when scratched, meaning micro-damage from ice expansion or contraction won't initiate rust like it would in steel. Over a 30-year roof life in your climate with 726 mm of rain and repeated temperature swings, this corrosion immunity eliminates the hidden rot and structural damage that eventually force early replacement of asphalt, wood, or traditional tile.

Yes—Interlock's four-way interlocking panels are warranted to resist winds up to 120 mph, which far exceeds Lake Church's typical peak gusts of 101 km/h (63 mph). The mechanical four-way interlock system means each panel is locked to its neighbors on all sides, distributing wind load across the entire roof rather than relying on fasteners alone. In a region where daily-max winds average 20 km/h and occasional spring storms can gust higher, this engineered redundancy gives you the security that asphalt shingles—which rely on adhesive and fasteners—simply cannot match.

The upfront cost of Interlock metal roofing is higher than asphalt, but over the roof's lifetime it becomes your last roof purchase. With asphalt shingles lasting 15–20 years in Wisconsin's climate, you'll replace them two or three times over 50 years; Interlock carries a lifetime limited material warranty for the original owner, plus a 50-year transferable term for the next owner. In Lake Church's 726 mm annual rainfall and 84 freeze-thaw cycles, asphalt degrades faster, leading to repairs, potential water intrusion, and eventual replacement. One Interlock roof eliminates the tear-off, labor, and landfill costs of multiple asphalt cycles.

Interlock Metal Roofing achieves UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty even covers perforation from hailstones up to 1.5 inches. Many insurers recognize this non-combustible, impact-resistant construction and offer discounts on premiums or deductibles. While discounts vary by carrier and policy, the combination of Class A fire rating availability, proven hail resistance, and 120 mph wind durability makes aluminum roofing a lower-risk proposition than asphalt. Contact your insurer with the ICC-ES ESR-1790 evaluation report and UL listing 33876 to explore available savings.

Aluminum cannot rust because it contains no iron—the element that oxidizes and corrodes in steel. Instead, aluminum forms a protective oxide layer that is self-healing; when scratched or exposed by weather, the layer reforms automatically. This is why Interlock has been installed from coastal salt-air homes to an Antarctic research station since 1998. In Lake Church, where humidity, 726 mm annual rain, and 105 cm snow create constant moisture exposure, this iron-free composition means no hidden rust damage, no structural decay, and no surprise collapses from internal corrosion like older steel or wood-based roofs experience.

Interlock aluminum requires far less maintenance than asphalt, wood, or tile. There are no shingles to curl, crack, or lose; no wood to split or rot; no tile to break. The Alunar fluorocarbon finish is warranted 30 years against chalking and fading, so repainting is rarely necessary. Occasional gutter cleaning and debris removal (as with any roof) are sufficient. Over Lake Church's 84 annual freeze-thaw cycles and with 105 cm of snow, asphalt shingles require constant inspection for damage, wood shingles demand sealing and repair, and tile needs broken-piece replacement. One roof inspection per year keeps Interlock performing; the other materials demand year-round vigilance.

Interlock carries The Guardian—a lifetime limited, non-prorated material warranty for the original owner covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. This warranty transfers once to the next owner for 50 years from completion. In a climate with 105 cm annual snow and 726 mm rain, no other residential roofing material offers this combination of protection and longevity. Asphalt lasts 15–20 years, wood 20–30 years, and traditional tile 40–70 years but requires constant maintenance and repair. Interlock's warranty reflects its true lifespan: a single roof for the life of your ownership and well beyond.

No structural reinforcement is needed. Interlock's Mediterranean Tile profile is about 96% lighter than concrete or clay tile, and the Slate weighs just 0.41 lb/sq ft—so light that it installs over most existing roofs without requiring framing upgrades. This is a major advantage in regions like Lake Church where the combination of 105 cm annual snow and existing roof loads creates structural stress. Installing over your current asphalt roof eliminates the cost, mess, and timeline of a complete tear-off, and the added insulation value from the air gap improves energy performance in a climate averaging about 3113 sunshine hours per year.

Yes. Interlock Metal Roofing has served the Lake Church and Sheboygan County region since 2001, bringing over two decades of experience installing Interlock panels in Wisconsin's demanding freeze-thaw, heavy-snow climate. They understand local building codes, the ICC-ES ESR-1790 compliance requirements, and how to optimize installation for 105 cm annual snowfall, 84 freeze-thaw days, and gusts to 101 km/h. Working with an established local installer means faster service, warranty support from someone who knows the regional weather challenges, and the confidence that your roof is installed to specification in conditions that demand precision.

Yes. Lake Church averages about 105 cm of snow, 726 mm of rain, roughly 84 freeze–thaw days a year, with peak wind gusts near 101 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.
