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

Metal roofs excel in heavy snow because aluminum's smooth surface naturally sheds snow loads before they accumulate dangerously. With about 92 cm of snow annually in Kelso Township, paired with roughly 78 freeze-thaw cycles each year, this matters. Interlock's four-way interlocking panels and optional snow guards keep snow from avalanching while the material's light weight—the Shingle profile weighs just 0.41 lb/sq ft—means your existing structure handles the load without reinforcement. The panels' design also interrupts ice dam formation by allowing proper drainage.

No. Aluminum's oxide layer actually protects it from freeze-thaw damage that degrades asphalt and wood shingles. Kelso Township experiences about 78 freeze-thaw days annually, a real stress test for roofing materials. Aluminum contains no iron, so it cannot rust or absorb moisture that causes cracking when frozen. The Alunar 70% PVDF coating is warranted 30 years against chalking and fading per ASTM D4214, and it's applied to both sides of every panel for extra defense in Minnesota's cycling winters.

Yes—Interlock panels are warranted to resist wind speeds up to 120 mph when installed to spec, well above Kelso Township's typical gusts of 103 km/h (about 64 mph). The four-way interlocking design means panels lock on all sides, distributing wind load across the entire roof system rather than concentrating stress on fasteners. This engineering addresses Minnesota's spring and fall wind season directly. Installation to specification is key, which is why working with an experienced local installer since 2001 matters for this region's climate.

Interlock achieves UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty even covers perforation from hailstones up to 1.5 inches. Class 4 resistance often qualifies homeowners for insurance discounts in hail-prone regions. The aluminum alloy (3105-H24 / 3003-H24, ASTM B209) is engineered specifically for impact durability. Ask your insurer about discounts; many recognize that metal roofing dramatically reduces hail-related claims. For Kelso Township properties, this translates to both peace of mind and potential savings over your roof's lifetime.

Aluminum contains no iron—the element that rusts—so it's chemically impossible for an aluminum roof to rust, period. When aluminum is scratched, it forms a new oxide layer automatically, healing the damage. Steel roofing lacks this self-healing property; scratches expose iron to moisture and rust begins. In Minnesota's 773 mm annual rainfall and 92 cm of snow, constant moisture exposure is the norm. Interlock's 3105-H24 and 3003-H24 aluminum alloy, bonded with Alunar coating on both panel sides, means decades of moisture won't compromise structural integrity the way rust compromises steel.

Almost certainly not. Interlock's Mediterranean Tile profile weighs only about 0.59 lb/sq ft—roughly 96% lighter than traditional concrete or clay tile—while the Cedar Shingle installs at 0.41 lb/sq ft. Most homes' existing framing easily carries this load. The real advantage: because metal roofs are so light, Interlock installs directly over most existing roofs without tear-off, saving thousands in labor and eliminating the landfill impact of old shingles. Your existing structure absorbs the weight of the new roof plus underlayment without reinforcement, letting you keep what's underneath and extend your home's durability immediately.

Metal roofing costs more upfront but becomes the last roof you buy. Asphalt shingles fail in 15–25 years; Interlock's Guardian Warranty is lifetime limited for the original owner, one-time transferable to the next owner for 50 years from completion. Over a 50-year period, you'll replace asphalt 2–3 times while maintaining one metal roof. Factor in asphalt's vulnerability to Minnesota's 78 annual freeze-thaw cycles, 773 mm rain, and 103 km/h gusts—all accelerate asphalt degradation—and metal's economics shift decisively. The transferable warranty also protects resale value in Kelso Township's market.

Interlock metal roofing requires virtually no maintenance—no algae treatment, no moss removal, no shingle replacement. Asphalt shingles degrade continuously under Minnesota's 78 freeze-thaw cycles annually and require regular inspection and spot repair. Wood shingles need regular treatment and split apart in freeze-thaw conditions. Aluminum won't rot, curl, crack, or split. The CALGreen-verified design reduces maintenance to occasional gutters cleaning. Over 50 years, this means no emergency repairs from freeze-thaw damage, no chemical treatments, no premature replacement. Your roof works silently while you focus on other priorities.

Interlock aluminum roofing achieves Class A fire classification—non-combustible—the highest fire rating available. This matters in wildfire-prone regions and increasingly for homeowners insurance and property resale. Aluminum cannot burn; it's already oxidized. The ICC-ES evaluation report ESR-1790 (reissued 2025) confirms compliance with IBC/IRC building codes, including fire performance standards. While Kelso Township's climate poses less wildfire risk than Western states, a Class A roof strengthens your home's overall resilience and may qualify you for insurance benefits.

Yes. Interlock aluminum is approximately 95% recyclable; at end of life, your roof becomes feedstock for new aluminum products indefinitely. Asphalt shingles are not recyclable and occupy landfills for centuries. Over Kelso Township's climate cycle, one asphalt roof typically ends up in a landfill by 2035, another by 2055. Your Interlock roof, installed today, will still be protecting your home in 2074 and beyond—and when eventually replaced, it returns to the aluminum supply chain. This closed-loop lifecycle eliminates the tear-off-to-landfill pattern entirely.

Yes. Kelso Township 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.
