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

No—aluminum actually thrives through freeze-thaw cycles because it has no iron and cannot rust, even when water penetrates the oxide layer. Jackson Park experiences about 79 freeze-thaw days per year, which would crack wood shakes or degrade asphalt's bond, but aluminum's crystal structure remains stable through repeated expansion and contraction. The 3105-H24 aluminum alloy and Alunar coating work together to withstand your region's roughly 88 cm of annual snowfall and the stress that comes with it. This is why Interlock panels install successfully from coastal salt-air homes to an Antarctic research station—material science, not luck.

Metal roofing sheds snow efficiently because of its smooth, sloped panel geometry and low thermal mass—it doesn't trap heat the way asphalt does, so it's less prone to the uneven melting that creates ice dams. With about 88 cm of snow annually and typical wind gusts reaching 96 km/h, snow shedding is a real advantage; the four-way interlocking panels stay watertight even as snow shifts. You can also install snow guards in the profile of your choice—Slate, Cedar Shingle, Shake, Tile, or Standing Seam—to control release safely. The light weight (Slate installs at about 0.41 lb/sq ft) means your existing structure handles the snow load without reinforcement.

Yes. The four-way interlocking panel design is warranted to resist wind speeds up to 120 mph (193 km/h), and your region's typical gusts top out around 96 km/h. The panels lock on all four sides—not just the edges—so even strong wind can't lift or separate them. Jackson Park's mean wind is roughly 22 km/h with seasonal variations, but metal roofing built to spec handles worst-case gusts without fail. That confidence comes from the engineering: when one panel interlocks with its neighbors in all directions, the whole roof acts as one unified system rather than individual shingles that can be compromised one at a time.

The opposite is true—metal roofing is so light that it eliminates structural concerns entirely. The Interlock Tile profile, for example, weighs only about 0.59 lb/sq ft—roughly 96% lighter than concrete or clay tile. Even the Shake profile at about 0.58 lb/sq ft is lighter than asphalt shingles on most older homes. You can install Interlock metal roofing directly over your existing roof in most cases, with no structural reinforcement needed. This is especially valuable in Jackson Park, where you're already managing about 88 cm of snow annually; the lightweight aluminum means you're actually reducing the total load your rafters carry compared to tearing off old shingles and replacing them with something heavier.

Why aluminum instead of steel for a roof in Wisconsin's wet climate?

Interlock metal roofing carries a UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty even covers perforation from hailstones up to 1.5 inches. This real durability often translates to insurance discounts because underwriters recognize that impact-rated metal roofing outlasts asphalt and resists damage that would require claims. While Jackson Park's hail risk is typical for Wisconsin rather than extreme, the Class 4 rating protects you against worst-case weather and gives you peace of mind that claims won't drain your coverage. Talk to your insurance agent about your specific policy; many carriers reward Class 4 metal roofs with measurable savings.

Metal roofing can reduce cooling costs through its reflective properties. Interlock's energy-efficient colors achieve initial solar reflectance up to 0.55 (Aged Copper Penny) and thermal emissivity of 0.84, which means they reflect heat that dark asphalt absorbs and re-radiates into your home. Jackson Park receives about 3,128 sunshine hours annually, so even in a northern climate, summer heat gain matters. The Cool Roof Rating Council has rated these colors specifically for their cooling performance. While Wisconsin winters are longer than summers, a reflective roof reduces daytime solar gain year-round and works with your HVAC system to lower overall energy costs—especially if you choose a lighter profile like Slate or Cedar Shingle that maximizes exposed surface area.

Virtually none compared to asphalt, wood, or tile. Asphalt shingles require moss removal, algae treatment, and frequent inspections for granule loss and curling. Wood shakes split, rot, and need annual sealing. Tile cracks and requires re-pointing. Aluminum doesn't rot, split, curl, or lose its fire rating—it just stays metal. The Alunar coating is warranted 30 years against fading and chalking, so your roof's appearance stays stable through Jackson Park's roughly 822 mm of rain and 88 cm of snow annually. Basic maintenance means keeping gutters clear and inspecting flashing after severe weather. That's it. The Guardian Warranty covers splitting, cracking, curling, rotting, and loss of impact resistance for the original owner's lifetime—non-prorated—so your only real cost is the rare contractor visit, not constant repairs.

The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner—meaning there's no deductible that grows over time, and it covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance from day one through your entire ownership. When you sell, the warranty transfers once to the next owner for 50 years from completion, which adds real resale value. Asphalt warranties typically last 20–30 years and are heavily prorated—after year 5 or 10, you're covering most repair costs yourself. With Jackson Park's 79 annual freeze-thaw days and roughly 88 cm of snow, material durability directly affects how long you own the roof versus how often you replace it. The math is simple: a roof you never have to replace is the last roof you ever buy.

Interlock Metal Roofing has served the Milwaukee County region since 2001 and is the authorized installer for Jackson Park and surrounding communities. That 20+ year track record means the contractor understands local building codes (ICC-ES ESR-1790 compliance is verified), local climate challenges like your region's 79 freeze-thaw days and 96 km/h wind gusts, and the practical details of installing over existing roofs. When you work with the local installer, you're getting someone who knows which profiles—Slate, Cedar Shingle, Shake, Tile, or Standing Seam—perform best in your neighborhood's specific weather patterns and architectural context. They handle the entire process from inspection and permitting through installation and warranty registration, so your roof is built to the manufacturing spec that earned ESR-1790 approval and UL 2218 Class 4 rating.

Yes. Jackson Park averages about 88 cm of snow, 822 mm of rain, roughly 79 freeze–thaw days a year, with peak wind gusts near 96 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.
