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

Yes—Interlock's four-way interlocking aluminum panels are engineered to shed snow and ice safely without damage. Thomson receives about 120 cm of snow annually, and your metal roof won't absorb moisture or weaken under freeze-thaw cycling like asphalt does. The smooth, hard surface allows snow to slide away naturally, reducing ice-dam formation. Unlike wood or slate, aluminum won't crack, split, or deteriorate during the region's roughly 84 freeze-thaw days per year. Snow guards are available if you want extra control over where snow exits. This durability—combined with a 120 mph wind warranty—means your roof performs consistently through Minnesota winters.

Aluminum's material science makes it uniquely resistant to freeze-thaw damage. Unlike asphalt (which becomes brittle in cold, soft in heat) or wood (which splits and checks), aluminum is non-porous and won't absorb water that expands when frozen. The 3105-H24 aluminum alloy holds its structural integrity through repeated 0°C crossings—Thomson averages about 84 such days annually. The Alunar 70% PVDF coating, warranted for 30 years against chalking and fading, also protects the metal underneath from thermal stress. You get a roof that actually strengthens in its bond to the panel rather than weakening, year after year.

Interlock metal roofing holds a UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty covers perforation from hailstones up to 1.5 inches. That durability often qualifies you for insurance discounts; contact your agent with the UL rating and ICC-ES evaluation report (ESR-1790). Minnesota hail events are real, and while Thomson's climate data doesn't isolate hail frequency, Class 4 impact resistance gives you concrete protection asphalt cannot match. Metal panels flex and recover rather than cracking or puncturing, so your roof maintains its integrity. Many insurers recognize this and reward you for choosing a non-degrading material.

Absolutely. Interlock panels are warranted to resist winds up to 120 mph when installed to specification—far exceeding Thomson's typical wind-gust speeds of around 98 km/h. The four-way interlocking design means each panel locks tightly to its neighbors, distributing wind load across the entire roof rather than stressing individual fasteners. Unlike asphalt shingles (which lift and tear) or loose tile, metal panels move as a unified system. This matters in a region where gusts are unpredictable; your roof won't degrade or require re-fastening after seasonal storms. The ICC-ES evaluation (ESR-1790) certifies this performance under IBC/IRC code.

You almost certainly need no structural reinforcement. Interlock's aluminum is extraordinarily light: the Slate profile installs at about 0.41 lb per square foot, and even the Mediterranean Tile—which replicates heavy clay or concrete—weighs roughly 0.59 lb/sq ft, about 96% lighter than real tile. Most existing roofs can handle this with no additional bracing. The real benefit: you can install Interlock directly over your current asphalt or wood shingles without tearing off the old material, saving labor and eliminating landfill waste. This overlay capability, combined with the weight advantage, makes metal roofing practical for almost every home in Thomson without expensive structural work.

Metal roofing requires far less maintenance than asphalt, wood, or tile. There's no cracking, curling, rotting, or splitting—the Guardian Warranty covers all of those against defect for the original owner's lifetime. You won't replace shingles after hail, recoat or re-stain wood shakes, or clean crumbling grout. Twice yearly, clear leaves and debris from gutters and valleys; in Thomson's 643 mm annual rainfall, good drainage matters. The Alunar 70% PVDF finish is rated for 30 years without fading or chalking, so no repainting needed. Compare that to asphalt (sealed or replaced every 5–10 years) or wood (stained every few years): metal is genuinely low-touch.

Metal roofing typically costs more initially than asphalt but becomes the last roof you buy. A standard asphalt roof lasts 15–20 years and requires replacement, removal, and landfill disposal each time. Interlock comes with a lifetime limited, non-prorated material warranty for the original owner and a 50-year transferable term for the next owner—meaning it easily outlasts two or three asphalt replacements. Factor in the savings: no tear-off labor, no landfill fees, no re-roofing every two decades, no maintenance costs for coating or repair. In Thomson's freeze-thaw climate (roughly 84 cycles yearly), asphalt degrades faster than in mild regions. Over 40 years, the total-cost-of-ownership favors metal decisively.

Yes, especially if you choose an energy-efficient color. Interlock's reflective coatings achieve initial solar reflectance up to 0.55 (Aged Copper Penny) and thermal emissivity of 0.84, rated by the Cool Roof Rating Council. In summer, when Thomson receives roughly 3025 sunshine hours yearly, these reflective colors bounce heat away rather than absorbing it as asphalt does. That directly reduces air-conditioning load, lowering your energy bill and peak-hour strain on the grid. The effect is most dramatic on south and west-facing roofs. In a climate with real winter (120 cm of snow), you still benefit in the warmer months, and reflective metal keeps heat from degrading your attic insulation year-round.

Installation timeline depends on roof size and complexity, but metal panels typically install faster than asphalt or wood because they're lightweight, pre-manufactured, and four-way interlocking (no overlapping seams to seal individually). Many residential roofs finish in 2–5 days. The real time-saver: Interlock installs directly over your existing roof in most cases. You skip the tear-off, haul-away, and debris-management labor that asphalt replacement requires—eliminating a full day or more of disruption and landfill impact. Our local installer, Interlock Metal Roofing, has served this region since 2001 and will walk you through the timeline for your specific home. Call for a site evaluation and accurate schedule.

The Guardian Warranty is a lifetime limited, non-prorated material warranty covering the original owner against rusting, rotting, splitting, cracking, curling, and loss of impact resistance—defects inherent to the product. Unlike prorated warranties (where coverage shrinks over time), this doesn't diminish with age. It's one-time transferable, giving the next owner 50 years of protection from the completion date. That's real peace of mind: you're not left stranded 20 years in if a panel fails, and your home's resale appeal includes a decades-long warranty for the buyer. Combined with the aluminum's proven track record since 1998—from coastal salt-air homes to an Antarctic research station—you have genuine assurance the roof will outlast your mortgage.

Yes. Thomson averages about 120 cm of snow, 643 mm of rain, roughly 84 freeze–thaw days a year, with peak wind gusts near 98 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.
