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

Aluminum's smooth, hard surface sheds snow and ice better than asphalt because it has no texture for water to grip during the roughly 79 freeze-thaw days per year that Hennepl County experiences. The four-way interlocking panels stay seated even as snow builds up, and the lightweight design—Interlock Slate installs at just 0.41 lb/sq ft—means your existing framing handles the load easily. With about 95 cm of annual snowfall and frequent thaw-refreeze cycles, that self-healing aluminum oxide layer resists the salt and moisture penetration that degrades conventional roofing.

Yes. Interlock panels are warranted to resist wind up to 120 mph, and the four-way interlocking design means each panel locks to its neighbors, distributing lateral force across the entire roof. Hennepin County's typical gusts reach about 94 km/h, well below that threshold. The warranty applies when installation follows specification, so the engineered connection is what matters—not the material's inherent strength. Winter storms here pose no unusual risk to a properly installed system.

Aluminum contains no iron, so it cannot rust chemically. Instead, it forms a transparent oxide layer that self-heals when scratched—a property that's especially valuable in Minnesota's wet climate of roughly 800 mm of rain per year. Steel roofing, by contrast, requires paint or coatings to prevent rust, and those break down. Here, the Alunar 70% PVDF fluorocarbon finish protects both sides of the panel and is warranted 30 years against chalking and fading, but the aluminum itself is your backup protection if the coating ever chips.

No. Aluminum's crystalline structure doesn't weaken when water enters micro-voids and freezes the way wood shingles or asphalt fibers do. With about 79 freeze-thaw days annually in Hennepin County and roughly 95 cm of snow, your roof faces intense cycling, but aluminum panels won't split, curl, or lose their structural integrity. The coating system is engineered to expand and contract with temperature swings, so repeated freeze-thaw actually proves aluminum's durability advantage over materials that become brittle or delaminate after years of this stress.

Interlock panels carry a UL 2218 Class 4 impact rating—the highest available—and the warranty even covers perforation from hailstones up to 1.5 inches. That certification matters to insurers. Many homeowners qualify for premium discounts when they install a rated metal roof, though you'll want to check with your agent because discount policies vary by carrier and location. Minnesota hail events are possible, and aluminum's non-combustible strength gives you measurable protection most asphalt roofs simply don't offer.

The Guardian Warranty is lifetime limited and non-prorated for the original owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It's also one-time transferable, giving the next owner 50 years of coverage from completion. Because aluminum doesn't rot and the PVDF coating is warrantied 30 years against fading, you're looking at a roof that easily outlasts two asphalt lifecycles. In Maple Plain's climate—roughly 3,100 sunshine hours per year plus freeze-thaw stress—that durability buys you genuine peace of mind.

When you calculate the total cost over the life of the roof, aluminum wins. Asphalt shingles need replacement every 15–25 years in Minnesota's wet, freeze-thaw climate; metal roofing covers the full lifespan of your home. Interlock panels don't degrade from the 800 mm of annual rainfall or 79 freeze-thaw days that age asphalt. You avoid the recurring costs of tear-off and disposal, plus metal roofs qualify for some tax credits and insurance discounts. The lifetime warranty, non-prorated for the original owner, means this is the last roof you buy.

No reinforcement needed. The Shake profile weighs just 0.58 lb/sq ft and the Mediterranean Tile profile about 0.59 lb/sq ft—roughly 96% lighter than concrete or clay tile. Most existing residential framing handles that weight easily, so Interlock installs over your current roof without structural work. That lightweight advantage means faster installation, lower labor costs, and no engineering delays. In a region with about 95 cm of annual snowfall, the light load also leaves your structural capacity as a buffer against heavy snow accumulation.

Interlock manufactures five profiles: Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile. Each replicates the texture and shadow line of its namesake material, so they deliver visual authenticity at the curb. The Slate profile suits modern and colonial aesthetics, Cedar Shingle reads traditional, Shake bridges rustic and contemporary, Tile works with Mediterranean or Southwestern homes, and Standing Seam suits clean-lined designs. All profiles carry the same non-combustible aluminum durability and Class 4 impact rating, so your aesthetic choice doesn't compromise protection.

Interlock Metal Roofing has served the region since 2001, bringing over two decades of local experience to Hennepin County installations. That tenure matters: the installer understands Minnesota's freeze-thaw cycles, snow loads of about 95 cm annually, and the wind gusts up to 94 km/h that require precise installation to meet the 120 mph warranty. Their familiarity with local building codes, permitting, and the quirks of retrofitting existing roofs means faster timelines and fewer surprises. When you call, you're working with people who've installed hundreds of systems in conditions exactly like yours.

Yes. Maple Plain averages about 95 cm of snow, 796 mm of rain, roughly 79 freeze–thaw days a year, with peak wind gusts near 94 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.
