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

Yes—aluminum actually thrives in freeze-thaw conditions. Salem Prairie experiences about 80 freeze-thaw days per year, which cracks asphalt shingles and splits wood shake over time. Aluminum has no moisture absorption, so it doesn't expand and contract the way asphalt or wood does. The 3105-H24 and 3003-H24 alloy used in Interlock panels meets ASTM B209 standards specifically for this kind of cycling. When the oxide layer does get scratched during installation or weather, it self-heals. That's why Interlock's been installed from coastal salt-air homes to an Antarctic research station since 1998.

Salem Prairie averages about 82 centimeters of snow annually, and Interlock's four-way interlocking system sheds both snow and ice efficiently because water can't pool under the panels the way it does under asphalt. The panels themselves weigh as little as 0.41 pounds per square foot for the Shingle profile, so they don't add load to your structure—your existing framing carries them without reinforcement. You can install custom snow guards if you want to control where snow slides off, and the four-way interlock keeps wind gusts up to 120 mph from lifting panels during winter storms when ice and snow add weight and stress.

The design is built for it. Salem Prairie experiences typical daily winds around 20 kilometers per hour with gusts reaching 99 kilometers per hour, and Interlock's four-way interlocking panels are warranted to resist wind speeds up to 120 miles per hour (193 km/h) when installed to specification. The interlock pattern doesn't rely on fasteners alone—each panel interlocks with its neighbors, distributing wind load across the entire roof system. That's why the product carries an ICC-ES evaluation report (ESR-1790) for IBC/IRC compliance. Winter storms that combine wind, ice, and snow are where this engineering really earns its keep.

Aluminum cannot rust because it contains no iron. Steel roofing oxidizes and forms rust that eats through the material; aluminum oxidizes and forms a self-healing oxide layer that actually protects what's underneath. Interlock uses roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209 certified), and it's coated on both sides with Alunar 70% PVDF fluorocarbon finish. That dual-side coating is especially valuable in areas with moisture stress—like Salem Prairie with its 835 millimeters of annual rainfall. Even if the coating or aluminum gets scratched, the oxide layer re-forms on its own. After 27 years of installation, no Interlock roof has needed replacement due to corrosion.

Asphalt costs less upfront but demands replacement every 15 to 20 years, plus maintenance, repairs, and debris removal. Interlock's Guardian warranty covers the original homeowner for life, non-prorated, meaning no deductibles or exclusions as the roof ages. Transfer to the next owner is 50 years from completion. Over three decades, you're buying asphalt twice and paying contractors twice; with Interlock, you're buying once. Energy savings also add up—energy-efficient colors reflect solar heat with initial reflectance up to 0.55, reducing cooling demand during the roughly 3,094 sunshine hours Salem Prairie averages annually. The math flips decisively in Interlock's favor when you total replacement, labor, and energy costs.

No structural reinforcement is needed. Interlock's aluminum panels weigh as little as 0.41 pounds per square foot for the Shingle profile and 0.59 pounds for the Mediterranean Tile—about 96 percent lighter than concrete or clay tile. Most existing residential framing can carry them without modification, which is why Interlock installs directly over your current roof in most cases. Compare that to a slate or tile job, which often requires engineering and costly framing upgrades. The light weight also matters during installation: crews work faster and safer, and there's less stress on your home during the transition. That's one of the practical reasons homeowners in Salem Prairie choose aluminum tile profiles when they want the look of heavy masonry materials.

Interlock carries a UL 2218 Class 4 impact rating—the highest available—and the Guardian warranty even covers perforation from hailstones up to 1.5 inches. That's substantial. While Kenosha County doesn't see the hail frequency of plains states, severe weather does happen, and one major hail event can total an asphalt roof. Insurance companies recognize the Class 4 rating and the durability of aluminum, and some offer premium discounts for metal roofing. It's worth asking your agent to compare quotes before and after the upgrade. The combination of impact resistance and a lifetime limited warranty against loss of impact resistance gives you and your lender real peace of mind.

Very little compared to asphalt, wood, or tile. Asphalt shingles need annual inspection, gutter cleaning, moss treatment, and flashing repairs; wood shake splits and rots and requires sealing; tile cracks and leaks. Interlock aluminum doesn't rot, split, crack, or curl—it's non-combustible (Class A fire rating available), won't grow moss, and needs only occasional gutter cleaning and a rinse-off if debris accumulates. The Alunar 70% PVDF coating is warranted 30 years against chalking and fading (tested to ASTM D4214 and D2244 standards), so color stays true even under Salem Prairie's roughly 3,094 annual sunshine hours. Most owners simply don't think about their roof once it's on—which is the whole point.

Asphalt shingles end up in landfills by the millions of tons each year; aluminum is approximately 95 percent recyclable and breaks the tear-off-to-landfill cycle. Interlock panels manufactured in Delta, BC since 1998 use roofing-grade aluminum alloy that can be re-melted and re-used indefinitely with no loss of properties. The energy-efficiency certification and Cool Roof Rating Council rating reduce the energy needed to cool homes—especially valuable across Salem Prairie's 3,094 sunshine hours annually—which lowers carbon footprint over the roof's lifetime. When you eventually recycle an Interlock roof decades from now, every ounce returns to the materials stream. Asphalt, by contrast, cannot be recycled into new roofing.

They can also advise on the five profiles available—Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile—and recommend which suits your home's style and your specific site conditions.

Yes. Salem Prairie averages about 82 cm of snow, 835 mm of rain, roughly 80 freeze–thaw days a year, with peak wind gusts near 99 km/h.
