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

Metal roofs shed snow and ice more readily than asphalt because aluminum conducts and radiates heat differently, and the smooth interlocking seams create no lip for snow to catch. Oakwood Knolls receives about 98 cm of snow annually with roughly 81 freeze-thaw days per year, which makes the self-healing oxide layer on Interlock's 3105-H24 aluminum especially valuable—it won't crack or embrittle as traditional materials do under repeated freeze cycles. You can add snow guards if you prefer to retain snow for insulation or control runoff direction.

When water infiltrates wood or asphalt shingles and freezes (a regular occurrence on Oakwood Knolls' 81 freeze-thaw days per year), it expands and cracks the material from inside. Aluminum doesn't absorb water and won't rot, split, or curl under those cycles. The ICC-ES ESR-1790 evaluation confirms Interlock's four-way interlocking panels resist this stress, and the Alunar 70% PVDF coating (warranted 30 years) protects against chalking and fading even when ice and salt are present. You eliminate the annual inspection worries that come with wood-based or asphalt roofs.

No—aluminum cannot rust because it contains no iron. When exposed to air and moisture (Oakwood Knolls averages 760 mm of rain yearly), aluminum forms a transparent oxide layer that self-heals when scratched, providing permanent protection. Interlock roofing uses roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209) and applies the Alunar fluorocarbon finish to both panel sides, which is especially critical in humid climates where corrosion risk is highest. You'll never face the rust staining or structural decay that can plague steel or galvanized roofs.

Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph, well above the gusts (about 97 km/h) recorded in Oakwood Knolls. The interlocking design locks each panel to its neighbors on all four sides, distributing wind load across the entire roof rather than relying on fasteners alone. This is verified in the ESR-1790 evaluation for IBC/IRC compliance, ensuring your roof meets Wisconsin building code requirements. High-wind events won't leave you with missing panels or leaks.

Hail impact resistance is measurable and insurable. Interlock metal roofing carries the highest impact rating available—UL 2218 Class 4—and the Guardian warranty even covers perforation from hailstones up to 1.5 inches. Many insurers recognize this and may offer premium discounts on homeowners policies because aluminum's rigidity and density mean it rarely dents or punctures, unlike asphalt or wood shingles. Contact your agent to ask about savings; the documentation of Class 4 rating often opens that conversation.

Yes, and the weight savings are dramatic. Interlock's Slate profile weighs only about 0.41 lb/sq ft, the Shake about 0.58 lb/sq ft, and the Tile about 0.59 lb/sq ft—roughly 96% lighter than concrete or clay tile. This means no structural reinforcement is needed, and the roof typically installs directly over your existing shingles without costly framing upgrades. The light weight actually reduces structural stress and helps older homes in Oakwood Knolls avoid settling or sagging issues that heavier materials can cause. Interlock has been installed from coastal homes to an Antarctic research station, proving the system performs under extreme conditions.

Interlock offers the Guardian Warranty—a lifetime limited, non-prorated material warranty for the original owner that covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance. That's one warranty the next owner can transfer once, extending coverage 50 years from completion. Manufactured since 1998 in Delta, BC, and installed worldwide (from salt-air coasts to Antarctica), Interlock aluminum roofs typically outlast three asphalt roofs. With about 3,073 sunshine hours annually in Oakwood Knolls, the 30-year Alunar coating warranty protects against fading and chalking under consistent UV exposure.

Upfront, metal costs more; over the roof's life, the math shifts dramatically. You'll replace asphalt shingles at least once (often twice) while your metal roof remains sound. Factor in the Guardian Warranty's non-prorated coverage, zero maintenance versus annual asphalt inspections, no seasonal repairs from 81 freeze-thaw days per year, and the potential for insurance discounts (Class 4 hail rating), and metal typically costs less over 40+ years. Many homeowners view it as their last roof—one purchase instead of a cycle of replacements and repairs.

energy-efficient Interlock colors with initial solar reflectance up to 0.55 and thermal emissivity of 0.84 reflect summer heat that asphalt absorbs and traps. While Oakwood Knolls averages 3,073 sunshine hours per year and a cool mean temperature of 8.5°C, summer days still demand air conditioning. A reflective metal roof reduces the temperature spike in your attic and can lower cooling run-time and costs. The Cool Roof Rating Council confirms the benefit, and you'll see the difference most clearly on clear, sunny days—which happen frequently throughout the Wisconsin year.

Interlock aluminum requires minimal maintenance: occasional leaf gutter cleaning and a rinse in salty air (if applicable). Unlike asphalt shingles, which degrade under Oakwood Knolls' 81 annual freeze-thaw cycles and need sealing or repairs, aluminum won't crack, curl, or lose granules. Unlike wood shake, it won't split or rot. Unlike tile, it won't break or require mortar repair. The CALGreen verification confirms reduced maintenance compared to traditional materials. Most homeowners inspect twice yearly (spring and fall) and find nothing to repair—that peace of mind is worth a great deal.

Yes. Oakwood Knolls averages about 98 cm of snow, 760 mm of rain, roughly 81 freeze–thaw days a year, with peak wind gusts near 97 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.
