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

Interlock aluminum panels shed snow and ice effectively because they're non-porous and shed water instantly—critical in a region that receives about 98 cm of snow annually and experiences roughly 81 freeze-thaw days per year. Unlike asphalt, which absorbs moisture and degrades under repeated freezing, aluminum's oxide layer is immune to ice damage. The four-way interlocking system and your choice of profiles (Slate, Shake, Tile, or Standing Seam) all perform identically in thermal cycling. Snow guards are available if you prefer to manage snowmelt differently. This material simply doesn't crack, curl, or split as the temperature swings between seasons.

Aluminum cannot rust because it contains no iron—the element that oxidizes and creates rust. When exposed to Drake's average 760 mm of annual rainfall, aluminum develops a thin, invisible oxide layer that actually protects the metal beneath and self-heals if scratched. Steel, by contrast, will rust from the inside out, especially in humid climates with freeze-thaw stress. Our 3105-H24 and 3003-H24 aluminum alloy is ASTM B209 certified, and every panel receives a 30-year Alunar fluorocarbon finish on both sides—extra insurance in wet conditions. After 27 years of installations from coastal salt-air homes to research stations, rust simply isn't a concern.

No—freeze-thaw cycling actually works in aluminum's favor. With roughly 81 freeze-thaw days annually in Drake, your roof experiences constant contraction and expansion. Asphalt and wood absorb moisture, freeze, expand, and crack. Aluminum is non-porous and non-absorbent, so it has no water to freeze and no internal stress. The material simply contracts and expands uniformly without degradation. The Guardian Warranty explicitly covers cracking, splitting, and curling—conditions that plague asphalt in freeze-thaw zones—and it's non-prorated for the original owner's lifetime. This is the one roof you buy; it won't fail under Wisconsin's seasonal swings.

Yes. Drake's typical gusts reach 97 km/h, and Interlock panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. The four-way interlocking system locks panels together at all edges, so wind cannot lift or separate them the way it can individual shingles. This ICC-ES ESR-1790 evaluated design has been tested and proven in extreme wind events. If your home sits on high ground or in an exposed location, the panel interlock provides the security that loose-laid materials cannot match. Your insurance company may also recognize this superior wind resistance.

Yes—aluminum's featherweight is one of its greatest strengths. The Slate profile installs at just 0.41 lb/sq ft, while the Mediterranean Tile (which replicates the look of traditional clay or concrete tile) weighs approximately 0.59 lb/sq ft—about 96% lighter than the real thing. This means no structural reinforcement is needed, and in most cases, Interlock installs directly over your existing roof, avoiding the cost and landfill impact of a tear-off. In a climate like Drake with 98 cm of annual snowfall, this lightweight design means snow load is handled efficiently without straining your home's framing. Your local installer has been serving the region since 2001 and routinely completes these overlays.

Over the life of your roof, aluminum breaks the cost equation fundamentally. Asphalt shingles last 15–20 years in Drake's 3073 annual sunshine hours and 81 freeze-thaw cycles, requiring replacement two or three times in 50 years. Interlock's non-prorated Guardian Warranty covers the original owner for life and transfers once—giving the next owner 50 years from completion. You'll buy asphalt three times; you'll buy Interlock once. Add minimal maintenance, no rusting or rotting, and the transfer clause boosting resale value, and aluminum is the last roof you buy. The total cost of ownership favors metal decisively over multiple asphalt cycles.

Interlock achieves UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty covers perforation from hailstones up to 1.5 inches. Wisconsin hail events are unpredictable, but this non-combustible aluminum design has proven resilience against severe impacts that would dent or crack asphalt and puncture wood. Many insurers recognize Class 4 impact resistance and offer premium reductions for metal roofs. Contact your agent with your roof's UL rating; the savings often offset a portion of the material cost. Over a 50-year lifespan, this durability advantage compounds.

energy-efficient Interlock colors with thermal emissivity of 0.84 and solar reflectance up to 0.55 (Aged Copper Penny) reflect heat that asphalt absorbs, reducing cooling demand. Drake's mean temperature is 8.5°C, but summer peaks stress air conditioning. Cool Roof Rating Council verification confirms this reflective performance. Unlike dark asphalt, which heats to 170°F+ and radiates that into your home, metal roofing stays significantly cooler. Combined with the rigidity of a solid deck and underlayment, you gain both passive cooling benefit and the acoustic benefit of a rain-quiet roof—no disadvantages, only efficiency gains.

Far less than asphalt, wood shake, or tile. Aluminum doesn't rot, split, curl, or lose impact resistance—conditions that trigger asphalt and wood maintenance cycles. In Drake's wet climate with 760 mm annual rainfall and 98 cm snow, asphalt gutters clog and shingles degrade rapidly. Your Interlock roof sheds water instantly and requires only occasional gutter cleaning—no moss treatment, no seal-coating, no shingle replacement. CALGreen verification documents the reduced-maintenance profile. The Alunar fluorocarbon finish (30-year warranty against chalking and fading) needs no re-coating. Over 50 years, the time and money you save on maintenance compounds into thousands.

Yes. Interlock aluminum achieves Class A fire rating—non-combustible, non-contributing to flame spread—and meets ICC-ES ESR-1790 evaluation for IBC/IRC code compliance (reissued 2025). Aluminum cannot ignite, so wildfire risk, embers, and structural fire exposure are mitigated at the roof level. While Drake isn't in a high-wildfire zone like western states, fire safety still matters for home insurance and peace of mind. Many insurers offer Class A roof credits. Non-combustibility also means your roof adds zero fuel load to a house fire, protecting interior spaces longer. This is a benefit most homeowners overlook until they need it.

Yes. Drake 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.
