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

Interlock metal panels shed snow effectively because aluminum doesn't expand and contract the way asphalt or wood does. Arlington receives about 92 cm of snow annually and experiences roughly 78 freeze-thaw days per year—conditions that crack and curl traditional shingles. Aluminum's stable coefficient of thermal expansion means the roof maintains its integrity through repeated freezing and thawing. The four-way interlocking system also resists ice-dam forces, and you can add snow guards to any profile if desired. Your roof stays weather-tight year after year without the fatigue damage that degrades asphalt.

Aluminum cannot rust because it contains no iron. Instead, a thin oxide layer forms on the surface—and this layer heals itself when scratched. Interlock uses roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209) with a Alunar 70% PVDF fluorocarbon finish on both sides. In Arlington's 773 mm annual rainfall and variable humidity, ferrous metals corrode from the inside out; aluminum simply ages gracefully. The 30-year coating warranty protects against chalking and fading (ASTM D4214), but the base material remains immune to rust—giving you decades of protection without the maintenance burden of rust-prone steel.

No. Freeze-thaw damage happens because water enters material pores, freezes, expands, and splits the structure—a problem with concrete tile, slate, and asphalt shingles. Aluminum is non-porous and has minimal thermal expansion; the 78 freeze-thaw days Arlington experiences annually cause almost no stress to the metal itself. Interlock's four-way interlocking panels and sealant design prevent water infiltration at panel edges. Combined with ICC-ES ESR-1790 code compliance and a lifetime limited warranty covering cracking, your roof won't delaminate or fracture the way traditional materials do in Minnesota winters.

Interlock metal roofing is extraordinarily light—the Mediterranean Tile profile installs at just 0.59 lb/sq ft, about 96% lighter than concrete or clay tile. This means no structural reinforcement is needed, and you can install Interlock directly over most existing roofs. The Slate profile weighs even less. In Arlington, where wood-frame homes are common, this lightweight approach avoids expensive structural upgrades that slate, clay, or concrete tile would require. You keep your existing roof deck, save on labor and materials, and get the appearance of premium materials without the structural burden. Installation typically happens faster and costs less than a complete tear-off.

Interlock roofing is warranted to resist wind speeds up to 120 mph (193 km/h) when installed to spec. Arlington's typical daily-max winds average 23 km/h with gusts up to 103 km/h—well below that threshold. The four-way interlocking aluminum panels lock together mechanically, creating a unified system that distributes wind load across the entire roof rather than relying on fasteners alone. This design has been tested per industry standards and validated in code evaluation ESR-1790. Your roof won't lift, separate, or lose panels in the seasonal gusts and storms Arlington experiences.

Interlock metal roofing carries a UL 2218 Class 4 impact rating—the highest available—and the warranty covers perforation from hailstones up to 1.5 inches. The aluminum panels absorb hail impact without cracking, splitting, or losing their water-shedding ability. Many insurers recognize this durability and offer premium discounts for non-combustible, impact-resistant roofing. Contact your agent to confirm your rate reduction; savings often offset part of the installation cost over time. In Minnesota, where spring hail is common, this impact resistance and potential insurance benefit provide real financial peace of mind.

energy-efficient Interlock colors reflect solar heat, reducing air-conditioning demand on hot days. Select profiles (like Aged Copper Penny) achieve initial solar reflectance up to 0.55 and thermal emissivity of 0.84, and are Cool Roof Rating Council certified. Arlington receives about 3209 sunshine hours per year—more than the national average—so reflective coatings meaningfully lower summer cooling costs. Light-colored aluminum reflects heat that asphalt shingles absorb and re-radiate into your attic. Over a 50-year roof life, this energy advantage compounds significantly, especially as cooling season temperatures trend upward. Your utility bills drop, and your home stays cooler without oversizing the HVAC system.

Metal roofing needs far less maintenance than asphalt, wood, or tile. Asphalt shingles require regular inspection for deterioration, granule loss, and curling—especially after Arlington's 78 annual freeze-thaw days. Wood shakes split and rot. Tile cracks and needs resealing. Interlock aluminum panels are non-combustible, don't split or rot, and the Alunar coating is warranted for 30 years against chalking and fading. You rinse debris annually and inspect fasteners—that's it. The CALGreen-verified design acknowledges reduced maintenance burden. Your only real task is gutter cleaning, which you'd do regardless. This low-maintenance profile translates to decades of worry-free protection.

Interlock includes The Guardian—a lifetime limited, non-prorated material warranty for the original owner covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It's also transferable once: the next owner receives 50 years of coverage from completion. This is exceptional. Most asphalt shingles last 15–20 years; composite tile might reach 25–30 years in favorable climates. Interlock aluminum, manufactured since 1998 in Delta, BC and installed worldwide from coastal salt-air homes to an Antarctic research station, has demonstrated 25+ years of field performance. In Arlington's moderate climate—773 mm rain, 92 cm snow, 3209 sunshine hours—the roof easily outlasts three generations of asphalt, and the transferable warranty adds significant resale value.

Yes. Interlock aluminum is approximately 95% recyclable—at end of life, the entire roof goes back into the aluminum supply chain. Asphalt shingles, by contrast, are torn off and sent to landfills by the millions of tons annually; they don't decompose meaningfully for centuries. Over a typical home's 50–100 year lifespan, you might install three asphalt roofs and generate tons of landfill waste. One Interlock roof lasts as long as all three asphalt roofs combined and ends the tear-off cycle entirely. When your aluminum roof does eventually retire, it retains full scrap value and becomes new aircraft fuselage, automotive parts, or cladding. This closed-loop sustainability, combined with Arlington's 773 mm annual rainfall (which an Interlock roof handles without degradation), makes metal the responsible long-term choice.

Yes. Arlington averages about 92 cm of snow, 773 mm of rain, roughly 78 freeze–thaw days a year, with peak wind gusts near 103 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.
