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

Yes—aluminum actually thrives in freeze-thaw conditions because it has no iron and cannot rust. Paris averages about 80 freeze-thaw days per year, which would cause wood to split and asphalt to crack, but aluminum's oxide layer self-heals when scratched and expands and contracts without permanent damage. The 3105-H24 aluminum alloy (ASTM B209) is rated for exactly these temperature swings, and the two-sided Alunar® 70% PVDF coating protects against corrosion for 30 years. You're installing a material that gets stronger with age in this climate, not weaker.

Metal roofing sheds snow faster than asphalt because its smooth surface and tight seams don't trap moisture—critical in a region that sees about 82 cm of snow annually. The four-way interlocking panels bond so tightly that ice damming risk drops dramatically; water runs freely to gutters instead of refreezing at the eaves. You can add snow guards if you want controlled shedding for safety. The weight advantage matters too: Interlock's Slate profile installs at only 0.41 lb/sq ft, so snow load isn't a structural concern the way it is with traditional slate or tile, and installation often goes over your existing roof without reinforcement.

Aluminum cannot rust because it contains no iron—the element that oxidizes and deteriorates in humid climates like Wisconsin's. Instead, aluminum forms a microscopically thin oxide layer that actually protects the metal underneath; if that layer is scratched, it self-heals in air. Combined with Alunar® two-sided PVDF coating (applied to both panel faces for extra salt-air and moisture protection), your Interlock roof is engineered to resist the moisture and humidity that corrodes steel, copper, and asphalt over Paris's ~835 mm of annual rainfall. This is why Interlock has been installed from coastal salt-air homes to Antarctic research stations since 1998 without rust claims.

Interlock's four-way interlocking panels are warranted to resist wind speeds up to 120 mph when installed to specification—well above Paris's typical wind gusts of about 99 km/h. The panels lock on all four sides, creating a unified system that prevents uplift and flutter; wind doesn't peel or separate them the way it can tear asphalt shingles. This redundant interlocking design is why the UL 2218 hail test (which includes high-wind stress) rated these panels at Class 4, the highest impact rating available. You're not just fastening shingles; you're installing a cohesive architectural shell.

Many insurers offer discounts for UL 2218 Class 4 roofing because impact resistance reduces claim frequency. Interlock's aluminum panels are rated Class 4—the highest available—and the Guardian Warranty even covers perforation from hailstones up to 1.5 inches, meaning your material is protected even if your insurer doesn't offer a discount. You'll want to contact your agent with the ESR-1790 ICC evaluation and UL 2218 rating to ask about your specific policy. Combined with wind resistance to 120 mph and a lifetime limited, non-prorated warranty, this roof is built to survive what Wisconsin's severe weather throws at it.

The math is straightforward: asphalt requires replacement every 15–20 years; Interlock is a one-time roof purchase. Over 50 years, you'd replace asphalt 2–3 times—removing and landfilling tons of material each time. Interlock's Guardian Warranty is lifetime limited and non-prorated for the original owner, with a 50-year transferable term for the next owner, covering rusting, rotting, splitting, and impact loss. You also skip the cycle of tear-offs, debris, labor costs, and roof access fees. The lighter weight (0.41–0.59 lb/sq ft depending on profile) often eliminates structural reinforcement costs that slate or tile demand. Initial cost is higher; lifetime cost is lower.

Metal roofing maintenance is minimal—occasional gutter cleaning and visual inspection. Unlike asphalt, which cracks, curls, and loses granules in freeze-thaw cycles (80 per year in Paris), aluminum does not degrade from moisture or temperature swings; the Alunar® coating is warranted 30 years against chalking and fading. Unlike wood shake or cedar shingles, there's no splitting, rotting, or moss growth to manage. CALGreen verification confirms reduced maintenance burden. You avoid the costly repairs and partial replacements that asphalt roofs require mid-life. Gutters handle ~835 mm of annual rainfall efficiently because the metal surface sheds water cleanly and seams remain tight—no pooling or leak pathways to monitor.

Interlock offers five profiles—Slate, Cedar Shingle, Shake, Mediterranean Tile, and Standing Seam—each replicating traditional architectural materials in aluminum. The Slate and Shingle profiles capture texture and dimension; the Tile profile delivers the curved aesthetic of clay or concrete (at ~96% lighter weight with no structural reinforcement needed). Standing Seam suits modern or industrial aesthetics. Because the material is aluminum, not a composite or painted steel, the look doesn't fade or weather differently over time—the Alunar® two-sided coating holds color and sheen for 30 years. You choose the visual profile that fits your home and neighborhood, knowing the durability won't match the appearance.

No, usually not. Interlock's extraordinary light weight is a major structural advantage. The Mediterranean Tile profile—which visually replicates heavy clay or concrete tile—installs at only 0.59 lb/sq ft, about 96% lighter than the actual tile it mimics. The Slate profile is even lighter at 0.41 lb/sq ft. This means installation often proceeds directly over your existing asphalt roof without expensive reinforcement, trusses, or structural upgrades. Steel or concrete tile would demand costly engineering and structural work; aluminum eliminates that burden. Lighter weight also reduces seismic load and wind-induced stress on the home's frame, a benefit in any climate but especially valuable in older Wisconsin homes with original framing.

Yes. Interlock Metal Roofing has been serving the Paris and Kenosha County region since 2001, bringing two decades of installation experience to this area's specific weather conditions—annual rainfall of about 835 mm, approximately 82 cm of snow, gusts to 99 km/h, and 80 freeze-thaw days per year. A local installer understands Wisconsin building codes (ICC-ES ESR-1790 compliance), local contractor networks for permitting, and the seasonal timing that works best for installation in this climate. You're not relying on a regional or national contractor unfamiliar with how freeze-thaw and lake-effect snow patterns affect Kenosha County homes.

Yes. Paris 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. 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.
