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

Aluminum's smooth, hard surface sheds snow and ice far better than asphalt, and with about 120 cm of snow annually and roughly 72 freeze-thaw days per year, that matters. The four-way interlocking panels are warranted to 120 mph wind, so spring gusts won't move accumulated snow. Unlike wood shakes or slate, aluminum doesn't absorb moisture or crack from repeated freezing—the material expands and contracts uniformly, and the self-healing oxide layer means ice dams won't compromise it. Snow guards are optional if you want to manage runoff.

No. Aluminum is inherently freeze-thaw proof because it contains no iron and cannot rust or absorb water. With 72 freeze-thaw days typical in this region and roughly 544 mm of annual rainfall, traditional materials like wood, asphalt, and clay tile all suffer dimensional damage—but aluminum expands and contracts as a single unit without absorbing moisture into grain or substrate. The roofing-grade 3105-H24 aluminum alloy (ASTM B209) and the Alunar 70% PVDF coating are engineered for exactly these cycles, with no splitting or delamination.

Yes. The four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph when installed to spec—well above the typical gust speeds of about 104 km/h (65 mph) recorded here. The mechanical lock between panels means wind cannot pry them loose, and the lightweight construction (Cedar Shingle profile at 0.41 lb/sq ft) reduces leverage. Even spring storms and winter blasts won't loosen or lift properly installed panels. If you live near open terrain, snow guards can be added to manage drift without compromising wind performance.

Almost never. Interlock's Slate profile weighs just 0.41 lb/sq ft, and even the Mediterranean Tile—which replicates heavy clay tile—weighs only about 0.59 lb/sq ft. That's 96% lighter than concrete or clay tile, so existing roof framing handles it without modification. Most homes can install over their existing asphalt shingles, eliminating costly tear-off and disposal. With Burlington Township's 120 cm annual snowfall, the lightweight design still handles snow load safely because the interlocking system distributes weight evenly across the structure. A local engineer may verify your specific home, but reinforcement is rarely needed.

Yes, when measured over the roof's lifespan. Asphalt shingles last 15–25 years and require replacement once or twice in your ownership; aluminum roofs come with a lifetime limited, non-prorated material warranty for the original owner and a 50-year transferable term for the next owner—effectively the last roof you buy. In Burlington Township's climate, with 97 cm of snow and 72 freeze-thaw days yearly, asphalt deteriorates faster due to UV exposure (about 3,145 sunshine hours annually) and freeze-thaw stress. Metal roofs avoid tear-off labor, landfill fees, and repeated replacement cycles. The energy savings from energy-efficient colors (solar reflectance up to 0.55) also reduce cooling costs over time.

The Guardian lifetime limited warranty covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance for the original owner—no prorated diminishment. It transfers once to the next owner, who receives 50 years of coverage from completion date. In a climate with 97 cm of snow, 72 freeze-thaw cycles, and roughly 544 mm of rain annually, this protection is comprehensive: freeze-thaw won't crack panels, moisture won't cause rot (because aluminum absorbs zero water), and hail up to 1.5 inches is covered under the UL 2218 Class 4 impact rating. Unlike asphalt shingles, you'll never file a weather-damage claim again.

Hail won't damage an Interlock roof. The panels carry a UL 2218 Class 4 impact rating—the highest available—and the warranty explicitly covers perforation from hailstones up to 1.5 inches. That rating means the roof has been impact-tested to withstand ice balls far larger than typical Minnesota hail. Many insurers recognize metal roofing's durability and offer premium discounts; contact your agent with the UL 2218 Class 4 certification to discuss savings. With Burlington Township's severe spring and summer weather patterns, a hail-proof roof eliminates the stress of storm claims and potential deductibles.

Virtually none. Aluminum doesn't degrade, split, or rot like wood shakes or asphalt shingles. With 544 mm of rain annually, asphalt develops algae and granule loss; wood absorbs moisture and splits in freeze-thaw cycles; clay tile cracks and leaks. Aluminum is CALGreen-verified for reduced maintenance: no moss growth (it's non-porous), no UV degradation beyond the 30-year coating warranty, and no loose seams or curling edges. Occasional gutter cleaning and inspection for debris (recommended for any roof) is sufficient. The solid deck and underlayment also mean a quiet interior—no rain noise to maintain or repair.

Yes. Aluminum is approximately 95% recyclable and never ends in a landfill; when a metal roof reaches end of life, it returns to the recycling stream. Asphalt shingles, by contrast, are torn off every 15–25 years and dumped as waste—over your home's lifetime, that's multiple roof-sized landfill contributions. Burlington Township's 97 cm annual snowfall and harsh climate mean asphalt replacement cycles accelerate due to UV and freeze-thaw stress. Choosing aluminum breaks that cycle permanently: you install once and the material cycles infinitely. The lightweight design also means no heavy tear-off labor or hazardous waste transport, reducing the carbon footprint of installation itself.

Yes. The extraordinary light weight of aluminum panels—Cedar Shingle at 0.41 lb/sq ft—allows installation directly over most existing asphalt roofs without tear-off. That saves labor, disposal fees, and installation time. Your local Interlock installer, serving the region since 2001, will assess your specific roof during a consultation to confirm no structural issues exist. Installation itself typically takes 1–3 days depending on roof complexity, and the process is cleaner and quieter than traditional roofing. With Burlington Township's typical wind gusts around 21 km/h and unpredictable weather windows, a faster installation means less weather exposure and faster completion of your project.

Yes. Burlington Township averages about 97 cm of snow, 544 mm of rain, roughly 72 freeze–thaw days a year, with peak wind gusts near 104 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.
