Metal Roofing in Wexford, Wisconsin — Lifetime Interlock® Aluminum Shingles Installed Locally

Metal roofs shed snow efficiently because the smooth, hard surface resists adhesion better than asphalt shingles do. With roughly 98 cm of snow per year and about 81 freeze-thaw cycles annually in Wexford, this matters: snow that partially melts and refreezes on asphalt creates damming ice; on aluminum, it slides off rather than bonding. The Interlock system's four-way interlocking panels also eliminate gaps where water can pool and re-freeze, eliminating ice-dam formation. Add snow guards if your roof pitch points toward a walkway or property line.

No. Aluminum expands and contracts with temperature swings, but it does this predictably and without degradation. With about 81 freeze-thaw days per year, Wexford is harsh on materials that crack or become brittle—asphalt, concrete, and wood all suffer. Aluminum's oxide layer self-heals when scratched, so even if the surface marks, it doesn't rust or absorb moisture. The Alunar 70% PVDF finish (warranted 30 years against chalking and fading) protects the underlying metal, and the four-way interlocking panel design accommodates micro-movement without compromising the weathertight seal.

Aluminum cannot rust because it contains no iron; steel does, and iron oxidizes into rust wherever moisture reaches it. Wexford averages about 760 mm of rain per year—enough to keep steel constantly vulnerable. Interlock uses roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209) with Alunar 70% PVDF finish applied to both sides of the panel, providing two layers of defense. Even if the coating is scratched, aluminum develops a thin, self-healing oxide layer that protects against further corrosion. Steel roofs require constant touch-up paint and eventual replacement; aluminum gets stronger as it ages.

Yes. Wexford sees typical daily winds around 22 km/h with gusts approaching 97 km/h, and Interlock's system handles that. The four-way interlocking panels lock together mechanically—each panel hooks into its neighbors on all four sides—so wind cannot peel up individual shingles the way it lifts asphalt tabs. The system is warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. That 2.5× safety margin above local gust speeds means your roof won't just survive Wisconsin storms; it'll outlast the fasteners on your gutters and the shingles on your neighbor's house.

No structural work needed. Interlock's Mediterranean Tile profile weighs only about 0.59 lb/sq ft, making it roughly 96% lighter than concrete or clay tile. That means it installs directly over most existing roofs without any frame upgrades. A concrete tile roof adds thousands of pounds that require additional framing; an Interlock tile roof is so light you can typically leave the old roof in place as additional underlayment. Wexford homes built before modern load-rating standards are especially well-suited to this: you get the tile look and durability without the cost and disruption of structural reinforcement.

Interlock achieves UL 2218 Class 4 impact rating—the highest available. The warranty even covers perforation from hailstones up to 1.5 inches. Class 4 impact resistance often qualifies homeowners for insurance discounts (typically 10–20%, depending on your carrier), so the material often pays for itself partly through premium savings. Some insurers recognize that aluminum roofs suffer less damage than asphalt in severe weather, especially across Wisconsin's spring and summer storms. Contact your agent with the UL 2218 certification number; they can quote your specific discount before you commit.

Yes, if you choose an energy-efficient color. Interlock offers energy-efficient finishes with thermal emissivity up to 0.84 and initial solar reflectance as high as 0.55 (Aged Copper Penny profile). These colors reflect heat that asphalt absorbs, so your attic and upper floors stay cooler on sunny days. Wexford enjoys about 3,073 sunshine hours per year, and even though Wisconsin summers are mild compared to the South, every degree of cooling reduces air-conditioning run time. Cool Roof Rating Council certification confirms the reflectance data. Pair an energy-efficiency finish with your metal roof's naturally low thermal mass, and you'll see measurable savings during hot spells.

Almost none. Asphalt requires moss removal, tab re-sealing, and gutter cleaning after every windstorm. Wood shake needs regular staining, fungicide treatment, and individual shake replacement. Aluminum? Rinse it with a garden hose once or twice yearly to clear dust and pollen. That's it. The Alunar 70% PVDF finish (30-year warranty) resists chalking and fading, so you don't repaint or seal it. Over Wexford's roughly 760 mm of annual rain, a metal roof self-cleans; water sheets off, carrying debris with it. The Guardian warranty doesn't require annual inspections or maintenance approvals, unlike some roofs. You save time, money, and ladder climbs for 50+ years.

Yes, if you stay in the house 20+ years or plan to sell within that window. Metal roofing costs more initially, but asphalt requires complete tear-off and replacement every 15–20 years; each cycle adds disposal costs and labor. One Interlock roof, warranted lifetime for the original owner (and transferable to the next owner for 50 years from completion), outlasts three or four asphalt roofs. Factor in zero maintenance costs, no emergency repairs from wind or hail damage, potential insurance discounts, and energy savings on summer cooling, and the math flips: you spend less total money over your ownership period. First cost is higher; total cost of ownership is lower. That's why this is called the last roof you'll buy.

The Guardian is a NON-prorated lifetime limited material warranty for the original owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. That's the stuff that ends other roofs. It's transferable once to the next owner, who gets 50 years of coverage from the completion date—so a roof installed today gives your buyer a half-century of warranty protection. The aluminum cannot rust (no iron in the alloy), the finish carries a separate 30-year chalking/fading warranty (ASTM D4214/D2244), and the ICC-ES evaluation (ESR-1790, reissued 2025) confirms the system meets or exceeds building codes. Combined with the four-way interlocking design and light weight, this warranty reflects genuine durability, not marketing.

Yes. Wexford averages about 98 cm of snow, 760 mm of rain, roughly 81 freeze–thaw days a year, with peak wind gusts near 97 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.
