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

Aluminum sheds snow efficiently because its smooth, hard surface and four-way interlocking panels create no purchase for ice dams—unlike asphalt, which traps moisture. Bassett experiences about 80 freeze-thaw days per year, and aluminum's non-corrosive properties mean repeated cycling won't degrade the material or the Alunar 70% PVDF coating (warranted 30 years). The metal expands and contracts predictably; fasteners and seams stay tight. Snow load calculations follow ICC-ES ESR-1790, so structural capacity is verified for your region's snow depth.

Interlock uses 3105-H24 and 3003-H24 aluminum alloy—metals that contain no iron, so rust chemically cannot form. Instead, aluminum develops a microscopically thin oxide layer that self-heals when scratched, protecting the metal beneath indefinitely. Bassett receives about 835 mm of rain annually, yet this moisture actually strengthens the oxide barrier rather than corroding it. The Alunar 70% PVDF fluorocarbon coating (both sides) adds a second defense, especially critical in freeze-thaw climates where water penetration accelerates failure in ferrous metals.

No structural reinforcement is needed. Interlock's Cedar Shingle weighs just 0.41 lb/sq ft, the Mediterranean Tile only 0.59 lb/sq ft—about 96% lighter than concrete or clay tile. This light weight means installation typically proceeds over your existing asphalt roof without adding load to rafters or walls. Even in Bassett's snow season (82 cm average), the combined weight of roof and typical snow load remains well within residential framing design. The Guardian Warranty covers the material itself, and ICC-ES ESR-1790 confirms code compliance for your region.

Yes. Interlock panels are warranted to resist wind speeds up to 120 mph (193 km/h), and Bassett's typical gusts average around 99 km/h—well within that rating. The four-way interlocking design locks adjacent panels on all sides, distributing wind forces across the entire roof rather than concentrating stress at fasteners. This redundancy is why the system performs in coastal salt-air installations and remote research stations. Installation to specification is key; a professional contractor ensures fastening pattern and underlayment meet the warranty standard.

Aluminum's atomic structure resists the cracking and degradation that plague asphalt, wood, and concrete through repeated freeze-thaw stress. Unlike asphalt, which becomes brittle in cold and embrittlement worsens with each cycle, aluminum maintains ductility across temperature extremes. Bassett's 80 annual freeze-thaw days and mean temperature of 9.9°C mean your roof experiences significant seasonal stress; aluminum's material properties prevent the micro-fractures that lead to leaks. The Alunar fluorocarbon coating (30-year warranty against chalking and fading per ASTM standards) doesn't degrade from UV exposure during those 3,094 annual sunshine hours either.

Interlock metal roofing achieves UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty covers perforation from hailstones up to 1.5 inches. This rating qualifies many homeowners for insurance premium reductions; contact your agent with the UL 2218 certification for a quote. In Bassett's climate, hail risk is present but less frequent than in plains states, yet the Class 4 rating provides peace of mind. The aluminum's non-combustible nature (Class A fire rating available) may unlock additional discounts, making the roof's cost competitive with asphalt over a 30-50 year horizon.

energy-efficient Interlock colors reflect heat with initial solar reflectance up to 0.55 and thermal emissivity of 0.84, cooling roof surface temperatures significantly compared to dark asphalt. Across Bassett's 3,094 sunshine hours per year, reflective coatings reduce heat absorbed into the attic, lowering air-conditioning load. Cool Roof Rating Council certification backs this performance. Summer cooling savings vary by home insulation and AC use, but the reflective advantage compounds over decades. Combined with aluminum's non-corrosive durability (no degradation reducing reflectance), you maintain energy efficiency throughout the roof's 50+ year life.

Interlock requires far less maintenance than asphalt, wood, or traditional tile. No algae grows on aluminum, no moss colonizes the surface, and seasonal debris (leaves, twigs) sheds naturally due to the smooth, hard finish. You'll inspect gutters and trim—standard for any roof—but the panels themselves don't require sealing, staining, or granule replacement. Bassett's 835 mm annual rainfall keeps the roof clean naturally. The four-way interlocking design eliminates exposed fasteners that corrode and loosen in freeze-thaw climates (80 cycles per year), whereas asphalt and wood roofs degrade fasteners steadily, requiring costly repairs.

Interlock's Guardian Warranty offers a lifetime limited, non-prorated material warranty for the original owner, transferable to the next owner for 50 years from completion. Over a 50-year horizon, this eliminates the asphalt replacement cycle (15-20 year lifespan, repeated tear-offs to landfill). Metal costs more upfront but outlasts asphalt by 2-3x, and the one-time installation avoids the labor and disruption of reroof cycles. Add the 30-year coating warranty (Alunar PVDF, ASTM tested), energy efficiency gains across 3,094 annual sunshine hours, and potential insurance discounts from UL 2218 Class 4 rating, and the total cost of ownership favors metal by mid-life.

Aluminum is about 95% recyclable at end-of-life, whereas asphalt shingles are landfilled by the millions of tons annually. Interlock's lightweight design (0.41-0.59 lb/sq ft) requires less material per home and installs over existing roofs, eliminating tear-off waste. Manufactured in Delta, BC, since 1998, the panels contain recycled aluminum content and are fully recyclable into future products. Bassett's 80 freeze-thaw days and 835 mm rain per year mean asphalt roofs here fail faster, driving more frequent replacements and landfill contributions. Choosing aluminum breaks this cycle—one installation, no repeat disposal, and eventual rebirth as aircraft components, automotive parts, or new roofing.

Yes. Bassett 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.
