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

Metal roofing sheds snow and ice faster than asphalt because the smooth aluminum surface and low weight prevent the heavy accumulation that leads to ice dams. Southside Township averages about 96 cm of snow yearly, and freeze-thaw cycles occur roughly 83 days per year—conditions that crack and curl asphalt shingles. Interlock's four-way interlocking panels stay locked tight through freeze-thaw stress, and the aluminum won't split or rot from trapped moisture. You can add snow guards to control slide-off if preferred, but the roof itself won't deteriorate from the snow load like heavier materials would.

No. Aluminum expands and contracts with temperature swings, but it does so uniformly and predictably without degrading—it simply won't crack, curl, or rot the way asphalt, wood, and concrete tile do over Southside Township's roughly 83 annual freeze-thaw days. The Guardian warranty explicitly covers cracking and curling because Interlock aluminum roofs don't suffer from them. With about 96 cm of snow and 683 mm of rain per year cycling through freezing and thaw, the aluminum oxide layer self-heals any micro-scratches from ice and debris. Your roof won't weaken after the tenth winter or the twentieth.

Aluminum cannot rust because it contains no iron. Instead, a naturally occurring oxide layer instantly forms on the surface and self-heals when scratched—a permanent shield against the moisture and road salt carried on Minnesota winds. Interlock panels are made from roofing-grade 3105-H24 aluminum alloy per ASTM B209, coated with Alunar 70% PVDF fluorocarbon finish on both sides, warranted 30 years against fading and chalking. Steel roofing, by contrast, requires constant vigilance against rust perforation. In Southside Township, where you get 683 mm of rain annually plus snow melt, that distinction means your roof won't develop rust spots, stains, or structural weakness—ever.

Yes. Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph—well above the roughly 108 km/h gusts typical for Southside Township. The panels lock together so tightly that wind can't peel or lift them, and the lightweight aluminum (Shingle profile at 0.41 lb/sq ft) won't create the sail effect that heavier roofs do in strong gusts. Because the panels interlock on all four sides, pressure changes can't find an edge to exploit. You get the storm durability of a roof engineered for coastal and mountain conditions without the weight penalty.

Interlock aluminum roofing carries a UL 2218 Class 4 impact rating—the highest available—and the warranty even covers perforation from hailstones up to 1.5 inches. The aluminum's inherent hardness combined with its four-way interlock design absorbs hail impact without cracking, splitting, or losing integrity the way asphalt, wood, and tile do. Many insurers recognize this durability and offer premium discounts for metal roofs; contact your agent with the UL 2218 Class 4 rating to ask. In a region where hail is possible, you're protecting your roof from damage and potentially your wallet from claim deductibles.

Yes, absolutely—in fact, metal roofing is lighter than your existing roof. The Interlock Tile profile, which replicates the appearance of concrete or clay tile, weighs about 0.59 lb/sq ft and is roughly 96% lighter than the real thing. The Shingle profile weighs just 0.41 lb/sq ft. You can install Interlock over most existing roofs without any structural reinforcement, which saves thousands in framing upgrades. Your home already carries the weight of its current roof plus snow load (96 cm annually in Southside Township), so switching to lightweight aluminum actually reduces the cumulative stress on your frame over the life of the roof.

Very little. Interlock aluminum requires only occasional rinses to remove pollen, dust, and debris—no roof repairs, no shingle replacement, no moss treatment. Asphalt shingles need regular inspections, gutter cleaning after each season, and eventual tear-off and replacement. Wood and tile require ongoing sealing and re-grouting. The Guardian warranty is non-prorated for the original owner, covering rusting, rotting, splitting, cracking, and curling—problems that don't occur with aluminum. CALGreen verification confirms reduced maintenance burden. Over 25 or 30 years in Southside Township's climate of 683 mm rain and 96 cm snow per year, you'll spend less time and money on roof maintenance than any other material.

energy-efficient Interlock colors reflect heat rather than absorb it, with initial solar reflectance up to 0.55 and thermal emissivity of 0.84 as rated by the Cool Roof Rating Council. That means less heat transfers into your attic and living spaces, reducing air-conditioning load on hot days. Southside Township receives about 3,127 sunshine hours per year, so reflective coating performance adds up over the cooling season. The difference isn't dramatic in Minnesota summers, but combined with the roof's longevity—you won't replace it in 15 years with a different material—the energy savings compound over decades. Metal roofing won't make you forget your AC bill, but it works with your HVAC system rather than against it.

Interlock aluminum costs more upfront but is the last roof you'll install. Asphalt shingles cost less initially but need replacement every 15–20 years; over 50 years, you'll buy and install three roofs and pay for tear-off and disposal labor each time. The Guardian lifetime limited warranty—non-prorated for the original owner and transferable to the next owner for 50 years from completion—means no replacement expense on your watch. Material durability through Southside Township's 83 annual freeze-thaw cycles and roughly 96 cm of snow avoids the premature failure that shortens asphalt life. When you factor demolition, disposal, reinstallation, and the disruption, metal roofing becomes cheaper per year over the long term.

Interlock Metal Roofing has served this region since 2001, with crews trained in four-way panel interlocking and installation over existing roofs—a critical skill because improper sealing leads to leaks and warranty disputes. They understand Southside Township's drainage patterns, snow loads, and wind exposure, and can advise on snow guards, underlayment, and ventilation specifics for your home. A local installer means faster response to questions during or after installation, familiarity with building department requirements, and accountability within the community. When you invest in a 50-year roof, working with an installer who's been in the region for two decades and stands behind their work makes a real difference.

Yes. Southside Township averages about 96 cm of snow, 683 mm of rain, roughly 83 freeze–thaw days a year, with peak wind gusts near 108 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.
