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

Interlock's four-way interlocking aluminum panels are engineered to support significant snow accumulation without sagging or leaking. With Franconia Township averaging about 92 cm of snow annually and experiencing roughly 83 freeze-thaw cycles per year, a metal roof's smooth, hard surface naturally sheds snow and ice rather than trapping it like asphalt. The panels lock together so tightly that ice dams cannot form underneath. Snow guards are available if you want additional retention for aesthetic or safety reasons. Aluminum's non-corrosive properties mean freeze-thaw cycling—which degrades asphalt and wood—does not damage it.

Asphalt absorbs water; when it freezes and thaws 83 times per year in Franconia Township, water expands inside the shingle, causing cracks and deterioration. Aluminum is non-porous and its oxide layer self-heals when scratched, so water cannot penetrate or damage it. The Alunar 70% PVDF fluorocarbon coating—warranted 30 years against chalking and fading—creates a protective shell on both sides of the panel. After 83 annual freeze-thaw cycles over decades, your metal roof looks unchanged while asphalt shingles are curling, splitting, and failing. This is why Interlock carries a lifetime limited warranty for the original owner.

Yes. Interlock's four-way interlocking panels are warranted to resist wind speeds up to 120 mph, which far exceeds the typical gusts of about 100 km/h (62 mph) common in Chisago County. The locking mechanism prevents panels from lifting, separating, or rattling during storms. Installed to specification over a solid deck, the system acts as one unit rather than thousands of independent shingles. This engineering is verified in ICC-ES evaluation report ESR-1790 and has been proven by installations spanning from coastal salt-air environments to extreme-weather research stations. Your insurance company may recognize this superior wind resistance.

Aluminum cannot rust because it contains no iron. When exposed to air, aluminum forms a thin oxide layer that actually protects the metal beneath; if scratched, this layer self-heals. The Alunar 70% PVDF fluorocarbon finish is applied to both sides of every Interlock panel—extra important in Minnesota's 778 mm annual rainfall and variable humidity. Steel roofing, by contrast, rusts from the inside out once the coating is breached, leading to staining, perforation, and structural failure. Interlock's material (3105-H24 and 3003-H24 roofing-grade aluminum per ASTM B209) plus its dual-sided coating means no rust-related repairs or replacement over the life of the roof.

No structural reinforcement is needed. Interlock's Slate profile installs at just 0.41 lb/sq ft, the Shake at 0.58 lb/sq ft, and the Mediterranean Tile at 0.59 lb/sq ft—about 96% lighter than actual clay or concrete tile. Most Minnesota homes are already overbuilt to handle snow loads of 92 cm annually, so a metal roof actually reduces the weight burden on your frame and foundation compared to traditional materials. You can install Interlock over most existing asphalt roofs without removing them, saving thousands in labor and landfill fees. Lightweight aluminum also means faster installation and less structural stress over the roof's 50+ year lifespan.

Interlock metal roofing carries a UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty covers perforation from hailstones up to 1.5 inches. Class 4 is rare and signals exceptional durability. Many insurance companies offer discounts on metal roofs because their impact resistance reduces claim frequency. In Minnesota's thunderstorm seasons, this protection matters. If hail does occur, the non-combustible aluminum and its Alunar coating are unaffected by the impact itself; there is no rust or water intrusion from the dent. Your insurer may recognize the reduced risk profile and adjust your premium accordingly—a benefit not available with asphalt.

Metal roofing costs more initially but is the last roof you will install. Asphalt shingles last 15–20 years in Minnesota's climate; you will replace them 2–3 times over 50+ years. Interlock's lifetime limited warranty for the original owner eliminates future replacement costs and labor. The Alunar coating is warranted 30 years against fading and chalking, meaning no repainting. Add in lower maintenance, no moss/algae treatment, and transferable 50-year coverage for the next owner (boosting resale value), and the total cost of ownership is lower than asphalt. Energy-efficient energy-efficient colors also reduce cooling costs in summer. Over a 50-year timeline, metal roofing saves money.

Virtually none. Unlike asphalt, which requires moss and algae treatment, periodic re-sealing, and nail-popping repairs, Interlock aluminum is maintenance-free per CALGreen verification. Rain (about 778 mm per year) and snow naturally clean it. No coating touch-ups, no wood rot risk, no rust inspections. The only routine task is clearing debris from gutters and ensuring snow guards function if installed. Compare this to wood shakes, which need staining and splitting repair, or clay tiles, which crack and re-grout over time. The Alunar 70% PVDF finish resists Minnesota's 3113 annual sunshine hours and freeze-thaw cycling without degradation, so your roof performs year after year with zero intervention.

Yes. Interlock offers five profiles: Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile. Each replicates the authentic texture and shadow lines of high-end materials while delivering the durability of aluminum. The Slate profile matches the clean geometry of natural slate; the Cedar Shingle and Shake profiles feature weathered wood grain and random coursing; the Mediterranean Tile has barrel-tile curves and Spanish-roof character; Standing Seam is modern and streamlined. All are available in multiple colors to suit your home's architecture. You get the premium aesthetic without the fragility—slate shatters in freeze-thaw, shake splits and rots, tiles crack. Aluminum is indestructible and instantly transforms your home's curb appeal.

Yes. Interlock aluminum is approximately 95% recyclable and breaks the asphalt tear-off cycle. When you replace an asphalt roof, the old shingles go to a landfill where they persist for decades. Metal roofing eliminates this waste stream entirely. At end of life (50+ years from now), your Interlock roof can be recycled into new aluminum products. The manufacturing process in Delta, BC is optimized for minimal waste. Additionally, energy-efficient Interlock colors reflect heat with initial solar reflectance up to 0.55 and thermal emissivity of 0.84, reducing cooling energy in summer and lowering carbon emissions. Over its lifetime, one metal roof prevents multiple asphalt roofs from entering landfills while reducing home energy consumption.

Yes. Franconia Township averages about 92 cm of snow, 778 mm of rain, roughly 83 freeze–thaw days a year, with peak wind gusts near 100 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.
