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

Metal roofing sheds snow and ice more effectively than asphalt because the smooth, hard surface and thermal reflectance prevent ice dams—critical in your region's 105 cm annual snowfall. Interlock's four-way interlocking panels stay structurally sound under snow weight, and because aluminum weighs only 0.41–0.59 lb/sq ft (the Mediterranean Tile profile is 96% lighter than concrete tile), no reinforcement is needed. With about 84 freeze-thaw days per year, this light weight combined with aluminum's non-corrosive oxide layer means the roof won't degrade as freeze cycles stress the material like they do asphalt or wood shingles.

No—aluminum roofing is immune to the damage freeze-thaw cycling causes to asphalt, wood, and clay. Your area experiences roughly 84 freeze-thaw days annually with average temperatures near 8.5°C, creating constant expansion-contraction stress that degrades traditional materials. Aluminum's crystalline structure accommodates thermal movement without splitting or curling, and the material contains no moisture-absorbing core like asphalt or wood. The Alunar 70% PVDF coating is warranted 30 years against cracking, and the lifetime limited Guardian Warranty explicitly covers cracking and curling—conditions you'd expect to claim on asphalt within 15–20 years.

Aluminum cannot rust because it contains no iron; instead, it naturally develops a thin, self-healing oxide layer that protects it from further corrosion even when scratched. Steel roofing, by contrast, requires protective coatings and eventually rusts through, especially in climates with 726 mm of annual rainfall and gusty conditions like yours. Interlock uses roofing-grade 3105-H24 and 3003-H24 aluminum (ASTM B209) with Alunar 70% PVDF coating applied to both panel sides—extra safeguarding in salt air and wet climates. This dual-layer protection means your roof resists the moisture and freeze-thaw stress that trigger rust in steel.

Yes—Interlock metal roofing is warranted to resist wind speeds up to 120 mph when installed to specification, well above your region's typical daily-max winds of 20 km/h and recorded gusts near 101 km/h. The four-way interlocking panel design locks each sheet to its neighbors on all sides, creating a unified roof system that distributes wind load across the entire assembly rather than letting individual panels lift or tear like shingles do. The ICC-ES evaluation report ESR-1790 (reissued 2025) confirms compliance with IBC/IRC wind standards, so your roof will perform reliably through the seasonal storms that challenge traditional roofing.

Interlock metal roofing carries the highest impact rating available—UL 2218 Class 4—and the warranty even covers perforation from hailstones up to 1.5 inches. This rating reflects the material's exceptional hardness and energy absorption, making hail damage extremely unlikely. Many insurers recognize this durability and offer premium discounts for metal roofing, though discounts vary by policy and carrier; contact your agent to confirm eligibility. Because metal roofs eliminate the frequent claim cycle asphalt roofs generate (weather damage, algae, granule loss), insurers see lower long-term risk, which translates into real savings for you over the 50+ year lifespan.

Yes—energy-efficient Interlock colors reflect solar heat rather than absorb it, with initial solar reflectance up to 0.55 and thermal emissivity of 0.84, meaning the roof bounces sunlight away and radiates absorbed heat efficiently. In Sheboygan Falls, where you average about 3113 sunshine hours per year, this reflectance reduces the cooling load on your home, lowering summer air-conditioning costs compared to dark asphalt. The Cool Roof Rating Council certification quantifies this performance, and over a 50-year roof life, the energy savings compound—particularly if you select one of the lighter energy-efficiency colors. Metal roofing isn't just about winter durability; it's a year-round energy tool.

Metal roofing requires virtually no maintenance beyond occasional gutter cleaning, whereas asphalt demands regular inspection, algae removal, and eventual granule replacement every 15–20 years. Interlock's aluminum surface doesn't degrade, split, curl, or attract moss like asphalt does in Wisconsin's 726 mm annual rainfall and damp climate. The Alunar coating is CALGreen-verified for reduced maintenance, and the non-porous aluminum surface sheds moisture instantly rather than absorbing it and rotting like wood or asphalt. With roughly 84 freeze-thaw cycles per year stressing traditional materials, you'll notice the difference: asphalt deteriorates visibly; metal stays silent and structurally sound for decades.

Yes—because Interlock panels weigh only 0.41–0.59 lb/sq ft, they install directly over most existing roofs without structural reinforcement, saving you 30–50% on tear-off labor and landfill costs. The installation process typically takes 3–5 days depending on roof complexity and size; the installer fastens panels to the existing deck, ensures proper drainage, and seals all penetrations. Interlock Metal Roofing has served the region since 2001 and can assess your specific roof and advise whether a tear-off is preferable for warranty or structural reasons. The overlay approach is faster, cheaper, and keeps old shingles out of the waste stream—a real advantage for a permanent roof.

Metal roofing is approximately 95% recyclable and requires no tear-off at end of life; at 50+ years, your roof becomes a valuable aluminum commodity rather than landfill waste. Asphalt shingles are replaced every 15–20 years in Wisconsin's challenging climate (726 mm rain, 105 cm snow, 84 freeze-thaw days per year), each replacement sending 8–10 tons per 1000 sq ft to landfills. Interlock aluminum is manufactured in Delta, BC, and installed globally—meaning the supply chain is optimized and the product's environmental footprint per year of service is far lower than asphalt. Choosing metal ends the asphalt tear-off-to-landfill cycle and invests in a permanent structure that holds recyclable value for generations.

Interlock offers the Guardian Warranty—a lifetime limited, non-prorated material warranty for the original owner covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. That means no prorated deductibles; the roof is simply repaired or replaced at no cost during your ownership. The warranty is one-time transferable to the next owner for 50 years from completion, adding significant resale value and peace of mind. This guarantee is backed by a company manufacturing aluminum roofing since 1998, with installations from coastal salt-air homes to an Antarctic research station—proven durability across every climate. For a Sheboygan Falls home expecting 50+ years of weather stress, this lifetime coverage is the difference between a renewable roof and a renewable promise.

Yes. Sheboygan Falls 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.
