Metal Roofing in Scandia Township, Minnesota — Lifetime Interlock® Aluminum Shingles Installed Locally

Metal roofing sheds snow and ice more reliably than asphalt because the smooth, hard surface resists accumulation and ice-dam formation. Scandia Township receives about 89 cm of snow annually across roughly 81 freeze-thaw cycles, conditions that crack and curl traditional shingles. Interlock's four-way interlocking aluminum panels remain rigid through temperature swings—aluminum does not split or curl like asphalt or wood—and the lightweight design (Slate at 0.41 lb/sq ft) means no structural reinforcement is needed even if snow does briefly cling to the roof before sliding off.

No; aluminum's crystalline structure actually strengthens in repeated freeze-thaw cycles, unlike asphalt or wood that degrade under thermal stress. Scandia Township experiences roughly 81 freeze-thaw days per year and mean temperatures around 6.2°C, creating conditions that accelerate damage to porous materials. Aluminum alloy 3105-H24 does not absorb moisture, so it cannot expand, contract, crack, or rot. The Alunar 70% PVDF coating—warranted 30 years against chalking and fading per ASTM standards—remains flexible and protective through this cycling, whereas asphalt becomes brittle.

Aluminum cannot rust because it contains no iron. Instead, a thin oxide layer forms on the surface and self-heals when scratched, making aluminum naturally corrosion-resistant even in humid or salt-adjacent environments. Scandia Township receives about 510 mm of annual rainfall and experiences regular freeze-thaw moisture cycles, conditions that would cause steel roofing to rust and require ongoing maintenance. Interlock's roofing-grade 3003-H24 and 3105-H24 aluminum alloys are ASTM B209 certified and have been installed in Antarctic research stations and coastal salt-air homes since 1998 without corrosion failure.

Interlock's four-way interlocking panels are warranted to resist wind speeds up to 120 mph, more than six times the typical 19 km/h gusts in Scandia Township and double the 90 km/h extreme gust speeds on record for the area. The interlocking design prevents wind from lifting or separating panels, and the UL 2218 Class 4 impact rating—the highest available—covers hailstone perforation up to 1.5 inches. Minnesota's spring storms and wind-driven rain encounter no gaps or weak points where water can penetrate, so your structure stays dry even in severe weather.

No structural reinforcement is required. The Interlock Slate profile installs at just 0.41 lb/sq ft, making it roughly 96% lighter than concrete or clay tile and light enough to install directly over most existing asphalt roofs. Scandia Township homeowners can avoid the cost and disruption of structural upgrades that slate, clay, or concrete tile would demand. The Mediterranean Tile profile, despite its authentic appearance, weighs only 0.59 lb/sq ft—a fraction of real tile—so your existing framing carries the load without modification. This weight advantage also reduces structural stress over the roof's 50-year-plus lifespan.

energy-efficient Interlock colors reflect rather than absorb solar heat, with thermal emissivity up to 0.84 and initial solar reflectance as high as 0.55 (Aged Copper Penny). Scandia Township receives about 3160 sunshine hours per year, and summer heat can push cooling costs upward even in a cold climate. Metal roofing's high reflectance means less heat enters your attic than with dark asphalt, reducing air-conditioning load on hot days. Cool Roof Rating Council certification confirms the thermal performance, and the reflective benefit persists because the Alunar 70% PVDF coating resists fading over 30 years.

The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance—conditions that commonly destroy asphalt and wood roofs within 15–20 years. The warranty is one-time transferable, providing the next owner 50 years of coverage from completion, which means your home's resale value is protected and future buyers inherit lasting protection. Combined with the Alunar coating's 30-year fade warranty and aluminum's intrinsic durability through Scandia Township's 81 annual freeze-thaw cycles, this is the last roof you'll install.

Metal roofing requires minimal maintenance—occasional gutter cleaning and inspection—versus asphalt shingles that crack, curl, and require repairs every few years or slate and tile that split and demand expensive specialist work. Scandia Township's 89 cm of annual snow and 510 mm of rain do not degrade aluminum because it does not absorb moisture, develop algae, or lose granules. The Alunar 70% PVDF coating resists fading and chalking per ASTM D4214 / D2244, and CALGreen verification confirms the roofing qualifies as reduced-maintenance. Over 30 years, asphalt requires tear-off replacement and repeated spot repairs; aluminum simply lasts.

Interlock aluminum roofing is approximately 95% recyclable, eliminating the asphalt tear-off-to-landfill cycle that repeats every 15–20 years. Asphalt shingles become landfill waste; aluminum panels are reclaimed and reused indefinitely. Scandia Township residents can choose a roofing material that ends the recurring demolition and disposal burden, reduces embodied carbon from repeated manufacturing and transport, and supports circular economy principles. The lightweight design (Slate at 0.41 lb/sq ft) also reduces transportation emissions compared to heavy tile or slate, and the 50-year transferable warranty means your roof stays in service—not in a truck to a disposal site—for generations.

Yes; aluminum is non-combustible, and Interlock roofing is available in Class A fire rating, the highest classification available. Aluminum cannot ignite or spread flame, making it inherently safer than asphalt shingles (which are combustible) or wood shakes (which are highly flammable). Scandia Township's building code compliance is covered by ICC-ES evaluation report ESR-1790, reissued in 2025 and valid under IBC/IRC standards, so Class A certification meets all local requirements. Homeowners with Class A metal roofing may also qualify for fire-insurance discounts, offsetting part of the roofing investment.

Yes. Scandia Township averages about 89 cm of snow, 510 mm of rain, roughly 81 freeze–thaw days a year, with peak wind gusts near 90 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.
