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

Interlock's four-way interlocking aluminum panels shed snow safely without degradation, even through Aurora's roughly 90 freeze-thaw cycles per year. Unlike asphalt shingles that crack and curl under repeated freezing, aluminum's oxide layer remains stable through endless temperature swings; it cannot absorb moisture and split like wood shakes. The panels are warranted to resist wind gusts up to 120 mph, so snow loads and ice weight combined stay well within engineered limits. Your roof emerges from winter exactly as it went in.

Aluminum contains no iron—the element that rusts—so corrosion simply cannot occur. When the aluminum surface scratches, it instantly grows a new oxide layer that protects the metal underneath. This self-healing property means freeze-thaw weathering, road salt spray, and winter moisture all leave no lasting damage. Steel roofing rusts because iron oxidizes; Interlock uses roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209) with a Alunar® 70% PVDF fluorocarbon finish on both sides, giving you permanent peace of mind through Wisconsin's 126 cm of annual snow and humid spring thaws.

No. Aluminum expands and contracts minimally compared to asphalt, wood, or stone—and it does so uniformly without cracking or warping. Aurora's roughly 90 annual freeze-thaw days cycle your roof continuously, but Interlock panels move as one piece rather than splintering like cedar shakes or crumbling like aged concrete tile. The four-way interlocking design accommodates natural movement while staying locked together. Guardian Warranty covers cracking and splitting for the life of your roof, reflecting the material's genuine durability through Wisconsin's harshest seasonal transitions.

Almost never. Interlock's aluminum panels weigh as little as 0.41 lb/sq ft for the Shingle profile and about 0.59 lb/sq ft for the Mediterranean Tile—roughly 96% lighter than concrete or clay tile. Most existing roof framing easily supports this load; no expensive structural reinforcement is required. Your home's current structure that carries asphalt shingles, wood shakes, or even existing architectural shingles can support Interlock without modification. This lightweight advantage also means installation is faster and safer, and you can often install over your existing roof rather than tear everything off first.

Interlock panels are warranted to resist wind speeds up to 120 mph when installed to specification. Aurora's typical wind gusts reach about 93 km/h (58 mph), so you have a substantial safety margin even in severe weather. The four-way interlocking design locks each panel to its neighbors on all sides, distributing wind load across the entire roof system rather than relying on fasteners alone. Class A fire rating is available for non-combustible protection. Combined with proper installation by your local Interlock installer—serving the region since 2001—this system gives you genuine security during spring and fall storm seasons.

Interlock aluminum panels carry UL 2218 Class 4 impact rating, the highest available, and the Guardian Warranty covers perforation from hailstones up to 1.5 inches. Many homeowners report insurance premium reductions after switching to a Class 4-rated metal roof, though actual discounts depend on your insurer's underwriting. Class 4 impact resistance means your roof withstands the severe hail that damages asphalt and composite shingles; aluminum's density and flexibility absorb impact without cracking. Contact your insurance agent with the product's UL listing (Intertek 33876) before installation to learn what savings may apply to your policy.

Interlock backs your roof with a lifetime limited, non-prorated material warranty for the original owner. The Guardian Warranty covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance—essentially all failure modes that would require roof replacement. If you sell your home, the warranty transfers once to the next owner for 50 years from completion, adding significant resale appeal. The Alunar® coating is separately warranted 30 years against chalking and fading. Manufactured since 1998 in Delta, BC, and installed from coastal salt-air homes to an Antarctic research station, Interlock panels have documented decades-long performance in extreme climates—a proven track record before your roof even goes up.

Unlike wood shakes that split and warp, asphalt shingles that curl and shed granules, or tile that cracks and requires frequent repair, Interlock aluminum roofing demands virtually no maintenance. Routine inspection is wise, but the panels don't need sealing, painting, or replacement of damaged units. Heavy snow (about 126 cm annually) simply slides off; gutters may need seasonal cleaning just as they would under any roof. The Alunar® fluorocarbon finish resists chalking and fading for 30 years, so color remains true even through Aurora's roughly 2,961 annual sunshine hours. Your roof simply performs year after year with minimal attention, freeing you from the upkeep that drains time and money from traditional materials.

Over a 50-year span—roughly the life of two to three asphalt roofs—Interlock metal roofing typically costs less in total because you buy it once and never again. Asphalt shingles degrade under Aurora's moisture (675 mm annual rainfall plus 126 cm snow), freeze-thaw stress, and UV exposure, requiring replacement every 15–25 years. Metal roofing eliminates the tear-off, haul-away, and reinstallation cycle. No emergency repairs from hail damage (UL 2218 Class 4 rated), no premature failure from ice damming or freeze-thaw splitting. The upfront premium dissolves when you factor in energy savings from reflective coatings and decades without replacement. For homeowners planning to stay long-term, the math strongly favors metal.

energy-efficient Interlock colors reflect solar heat rather than absorbing it like dark asphalt. Reflectance reaches up to 0.55 (on Aged Copper Penny), and emissivity is 0.84, meaning the roof re-radiates absorbed heat efficiently. On Aurora's roughly 2,961 annual sunshine hours, this cooling effect runs year-round on sunny days. Cool Roof Rating Council verification confirms performance across standard testing. Summer air-conditioning runs less frequently, cutting utility bills noticeably over months and years—a benefit that compounds with rising energy costs. Winter sun also warms your home slightly, reducing heating load. The lightweight panels install over existing roofs, so you gain energy efficiency without the waste and cost of tearing off old materials.

Yes. Aurora averages about 126 cm of snow, 675 mm of rain, roughly 90 freeze–thaw days a year, with peak wind gusts near 93 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.
