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

Aluminum sheds snow and ice far better than asphalt because its smooth, hard surface prevents adhesion; Rowland averages about 95 cm of snow annually and roughly 79 freeze-thaw days, conditions that crack and curl asphalt shingles over time. Interlock panels are manufactured to withstand these cycles without splitting or curling—properties explicitly covered in The Guardian warranty. Four-way interlocking seams also prevent water infiltration during the thaw phases that plague traditional roofs in your climate.

No. Interlock roofs use roofing-grade 3105-H24 and 3003-H24 aluminum alloy, which contains no iron and therefore cannot rust. When aluminum scratches, its oxide layer self-heals automatically. The Alunar 70% PVDF fluorocarbon finish—applied to both sides of every panel and warranted 30 years against chalking—provides an additional barrier against Minnesota's roughly 796 mm of annual precipitation and salt used on roads. This two-layer defense makes aluminum fundamentally more durable than steel roofing in northern climates.

No structural reinforcement is required. The Interlock Mediterranean Tile profile weighs roughly 0.59 lb/sq ft—about 96% lighter than concrete or clay tile—so it installs directly over most existing roofs without load concerns. Even the heavier Shake profile at approximately 0.58 lb/sq ft is negligible compared to traditional tile. This weight advantage means you avoid tens of thousands in structural upgrades, and installation can proceed faster because your home's framing already supports the load.

Yes, with confidence. Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. Rowland's typical gusts reach about 94 km/h, well within the rated capacity. The interlocking design—not fasteners alone—distributes lateral forces across the entire roof system, meaning even severe spring and autumn storms pose no risk to panel retention or integrity.

Interlock achieves the highest hail rating available: UL 2218 Class 4 impact resistance. The warranty explicitly covers perforation from hailstones up to 1.5 inches. The non-combustible aluminum and robust panel construction often qualify homeowners for insurance premium discounts that offset installation cost over the roof's life. Combined with Minnesota's hail exposure and your 79 annual freeze-thaw cycles, impact durability protects both your home and your long-term insurance expenses.

The Guardian is a lifetime limited, non-prorated material warranty for the original owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance—conditions common to Minnesota's severe weather. It transfers once to the next owner for 50 years from completion, protecting future resale value. No other roofing material matches this coverage depth: asphalt typically lasts 15–20 years; metal roofs from Interlock are designed and warrantied for the life of the home.

Installation timelines vary by roof size and existing conditions, but Interlock's lightweight panels—at 0.41 to 0.59 lb/sq ft depending on profile—install faster than tile or slate. A major advantage in Rowland's climate: metal roofing can be installed over your existing asphalt roof, eliminating tear-off labor and disposal cost, and speeding project completion before winter weather arrives. The local Interlock installer, serving the region since 2001, can provide a precise timeline during your consultation.

energy-efficient Interlock colors achieve solar reflectance up to 0.55 with thermal emissivity of 0.84, meaning they reflect heat that dark asphalt absorbs. In Rowland's approximately 3,128 annual sunshine hours, reflective metal panels reduce heat transfer into the attic, lowering air-conditioning demand in summer. The Cool Roof Rating Council rating quantifies this benefit. Over a 50-year lifespan, energy savings compound while asphalt absorbs and re-radiates heat every sunny day.

Interlock aluminum is approximately 95% recyclable, ending the cycle of tearing off asphalt shingles and sending them to landfill every 15–20 years. Over Rowland's ~796 mm annual rainfall, your roof sheds water without degrading, shedding no particles into storm systems. A single Interlock installation replaces 3–4 asphalt roofs over 50+ years, eliminating four roofing tear-offs and their associated waste and emissions. The material's longevity transforms roofing from a consumable into a durable asset.
