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

Yes. Aluminum expands and contracts with temperature swings, but it doesn't crack, curl, or split the way asphalt and wood do through freeze-thaw stress. Union Grove experiences about 80 freeze-thaw days per year; aluminum's oxide layer (which forms naturally on the material) remains intact regardless of thermal cycling. The four-way interlocking panels accommodate movement without trapping ice, and the Alunar 70% PVDF coating—warranted 30 years against chalking—handles salt air and moisture better than asphalt exposed to the same freeze-thaw abuse.

Interlock's aluminum panels shed snow efficiently because the smooth, interlocking design prevents ice dams—a major problem in areas receiving about 82 cm of snow annually. The roof's extraordinarily light weight (Cedar Shingle installs at 0.41 lb/sq ft) means accumulated snow won't stress your structure the way slate or clay tile would. Snow guards are available if you want to control roof runoff. The standing seam and shake profiles are especially popular in snow-prone regions because their geometry naturally breaks up ice formation.

No. Aluminum contains no iron, so it cannot rust—period. The roofing-grade 3105-H24 aluminum alloy (ASTM B209 standard) forms a thin, self-healing oxide layer that protects the metal. When scratched or exposed, that oxide regenerates automatically. Union Grove's average of 835 mm annual rainfall and occasional salt-air transport won't corrode aluminum the way it corrodes steel. The Alunar finish applied to both sides of every panel adds a 30-year warranty barrier, making this roof impervious to the damp Midwest climate.

Yes. Interlock's four-way interlocking panels are warranted to resist wind speeds up to 120 mph. Union Grove experiences typical daily-max winds around 20 km/h with gusts reaching 99 km/h—well below that threshold. The interlocking design—where each panel hooks into its neighbors on all four sides—distributes wind load across the entire roof system rather than relying on fasteners alone. This engineering means your roof stays secure during the spring and fall storms Racine County regularly sees.

No. The Mediterranean Tile profile, for example, is about 96% lighter than concrete or clay tile, yet delivers the same aesthetic. Cedar Shingle installs at just 0.41 lb/sq ft—comparable to asphalt shingles. This means you can install Interlock over most existing roofs without structural upgrades, saving thousands on labor and framing. Interlock even installs over many single-layer asphalt roofs without tear-off, reducing waste and disruption. Your home's existing rafters handle it with ease.

Interlock achieves UL 2218 Class 4—the highest hail rating available—and the Guardian Warranty even covers perforation from hailstones up to 1.5 inches. That rating often qualifies you for homeowner's insurance discounts (check with your carrier). With about 3,094 sunshine hours and occasional severe weather in Racine County, the impact resistance is peace of mind. Class A fire classification is also available (non-combustible aluminum), which may lower premiums further and meets ICC-ES ESR-1790 code requirements.

energy-efficient colors reflect heat rather than absorbing it like asphalt does. Interlock's reflective coatings achieve initial solar reflectance up to 0.55 (Aged Copper Penny) with thermal emissivity of 0.84—meaning the roof stays cooler in the 3,094 annual sunshine hours Union Grove receives. In summer, that reduces air-conditioning load and utility bills. The Cool Roof Rating Council verified this performance, making Interlock a smart choice for energy-conscious homeowners in climates with significant warm-season sun exposure.

The Guardian Warranty provides a lifetime limited, non-prorated material guarantee for you (the original owner) covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It's transferable once to the next owner for 50 years from completion. Unlike asphalt (typically 15–20 years), Interlock is designed to outlast your ownership. Manufactured since 1998 in Delta, BC, and installed from coastal homes to Antarctic research stations, these roofs have proven durability across extreme climates far harsher than Union Grove's 80 annual freeze-thaw days.

Five profiles are available: Slate (clean, contemporary), Cedar Shingle (rustic charm), Shake (dimensional texture), Standing Seam (modern lines), and Mediterranean Tile (Old World elegance). Each replicates traditional materials in aluminum—no maintenance of actual wood or tile required. The Slate profile suits modern farmhouse designs; Cedar Shingle and Shake appeal to traditional homes; Tile works on Mediterranean or Spanish-Colonial architecture. Standing Seam complements contemporary builds. All profiles handle Union Grove's 835 mm annual rainfall and 82 cm of snow without leaking, splitting, or rotting.

They can advise on which profiles and colors work best for your home's orientation relative to the 3,094 annual sunshine hours and typical wind patterns, and they stand behind their work.

Yes. Union Grove 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.
