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

Yes—aluminum's smooth, interlocking surface sheds snow and ice far more effectively than asphalt, which traps moisture and promotes ice damming in your freeze-thaw cycle of about 81 days per year. Genesee receives roughly 88 cm of snow annually, and the four-way interlocking panels create a unified plane that prevents snow from bonding to the substrate the way it does on shingles. Snow guards can be added if you want controlled shedding. The lightweight design—just 0.41 lb/sq ft for the Shingle profile—means no structural stress from accumulated snow load, and the material's durability through repeated freeze-thaw actually improves with age rather than deteriorating like asphalt.

Aluminum cannot rust because it contains no iron—the element that oxidizes and corrodes. Instead, aluminum naturally forms a thin oxide layer that self-heals when scratched, providing permanent protection without maintenance. This is especially important in Genesee, where you experience about 775 mm of annual rainfall and moisture exposure. Steel roofing requires protective coatings that eventually wear away; aluminum's protection is built into the material itself. The Alunar 70% PVDF fluorocarbon finish on both sides adds a 30-year warranty against chalking and fading, but even if that coating wore away completely, the aluminum substrate would remain sound. This lifetime durability is why the Guardian Warranty covers corrosion for the original owner with no time limit.

The Guardian Warranty is a lifetime limited, non-prorated material warranty for you as the original owner—it covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance with no time cap. If you sell your home, the warranty transfers to the next owner for 50 years from completion, a significant selling point. Unlike prorated warranties that fade year by year, you're protected equally in year 5 and year 50. Given Genesee's demanding climate—about 88 cm of snow, 81 freeze-thaw cycles annually, and wind gusts reaching 100 km/h—this non-prorated protection means costly repairs or premature replacement simply don't happen. You're buying your last roof, and that certainty has real financial and peace-of-mind value.

No. Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification—far beyond Genesee's typical gusts of about 100 km/h. The interlocking design means each panel is mechanically locked to its neighbors on all four sides, creating a unified system rather than individual shingles that can lift. Genesee experiences regular gusts that would stress asphalt shingles, but the metal roof only gets stronger as wind pressure increases, pulling the panels tighter together. Installation over a solid deck with proper fastening—standard practice here—ensures your roof will outlast any storm typical to Waukesha County. Insurance companies often recognize this durability and may offer premium reductions.

Aluminum excels in freeze-thaw environments because it expands and contracts uniformly without cracking, splitting, or becoming brittle—properties that make wood and asphalt shingles fail in your climate. Genesee averages about 81 freeze-thaw days per year, and aluminum's non-porous structure means water doesn't penetrate and expand inside the material during freezing. The roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209 certified) was designed for exactly these conditions and has been installed since 1998 in climates from coastal salt air to Antarctica. Asphalt becomes brittle when temperatures drop repeatedly, leading to cracking and curling; wood absorbs moisture and splits. Aluminum simply cycles through temperature changes without degradation, which is why the material warranty makes no distinction between freeze-thaw damage and other claims.

Yes, if you choose an energy-efficient color. Interlock offers reflective finishes with solar reflectance up to 0.55 and thermal emissivity of 0.84, rated by the Cool Roof Rating Council. These colors bounce heat away rather than absorbing it the way dark asphalt does, reducing roof surface temperature by 20–30°F on sunny days. Genesee receives about 3,074 sunshine hours per year, so this reflection matters through summer. The energy savings vary by color, roof pitch, and insulation, but energy-efficiency-certified metal roofs are proven to lower cooling energy use—and in Wisconsin, that's meaningful during your warmest months. Unlike asphalt, which darkens over time and absorbs more heat, the coating is warranted 30 years against fading, so reflectance stays consistent.

Metal roofing is actually more hail-resistant than asphalt, and Interlock's aluminum carries UL 2218 Class 4 impact rating—the highest available—with warranty coverage even for perforation from hailstones up to 1.5 inches. Class 4 is the same rating that protects luxury vehicles and skylights, so you can expect minimal or no damage from typical Wisconsin hail. Many insurers recognize this durability and offer premium discounts for impact-rated metal roofing, potentially recouping part of your roof cost over time. Asphalt shingles take damage from much smaller hail and often require claims. Ask your agent about discounts when you install; having the UL 2218 Class 4 rating in your paperwork makes the conversation straightforward.

Yes. The extraordinary light weight of aluminum—about 0.41 to 0.59 lb/sq ft depending on profile—means installation over most existing roofs requires no structural reinforcement. Your home's framing was designed to carry asphalt shingles plus snow load (Genesee gets roughly 88 cm annually), and aluminum is a fraction of that weight, so no upgrades are needed. Interlock Metal Roofing, serving the region since 2001, handles this process routinely. Pros: faster installation, no tearoff labor or landfill fees. The installer will inspect your existing deck for damage, repair as needed, add underlayment and solid deck where required, and install the new roof. Tearoff is an option if your existing shingles are severely damaged or if you prefer a fresh substrate—your local installer will advise based on your roof's condition.

Virtually none beyond occasional inspection. Aluminum does not rust, rot, split, crack, or curl—it has no organic material that deteriorates. Asphalt shingles require gutter cleaning and inspection for loose or missing pieces every couple years; wood shakes need treatment and repair; tile requires reseating. Your metal roof will not need roofing repairs. Debris may collect in valleys (as with any roof), so clearing leaves and branches keeps gutters flowing, but this is routine home maintenance, not roof maintenance. The Alunar fluorocarbon finish is warranted 30 years against chalking and fading, so even the coating lasts longer than most asphalt roofs. Genesee's 775 mm annual rainfall and 100 km/h wind gusts cannot degrade aluminum the way they break down asphalt over 15–20 years. You trade zero maintenance for a roof that outlives every other choice.

Interlock offers five authentic profiles: Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile. Each replicates the real thing with dimensional shadow lines and texture, so a Slate metal roof looks like slate, a Cedar Shingle like cedar, and so on. You choose the look you want—classic, rustic, or elegant—and get aluminum's performance underneath. All profiles are available in multiple colors (Aged Copper Penny, charcoal, forest green, etc.) to match your home's style and Genesee's neighborhood character. Because aluminum is lightweight—the Tile profile is about 96% lighter than concrete or clay tile—you can install it over your existing roof without reinforcement, regardless of which style you choose. Homeowners often pick a profile based on what suits their home's architecture, then let the durability and low maintenance win them over.

Yes. Genesee averages about 88 cm of snow, 775 mm of rain, roughly 81 freeze–thaw days a year, with peak wind gusts near 100 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.
