Metal Roofing in Brewer’s Hill, Wisconsin — Lifetime Interlock® Aluminum Shingles Installed Locally

Yes — aluminum's oxide layer actually strengthens when exposed to freeze-thaw stress, unlike asphalt or wood that crack and curl. Brewer's Hill averages about 79 freeze-thaw days per year, where temperature swings are hardest on brittle materials. Interlock's 3105-H24 aluminum alloy is naturally ductile, flexing through those temperature shifts without permanent damage. The Alunar coating (warranted 30 years against chalking) adds another protective layer, so your roof stays intact through decades of Wisconsin's harshest seasonal transitions.

Metal roofs shed snow and ice far more effectively than asphalt because their smooth, hard surface prevents ice from bonding and allows snow to slide off naturally — especially important in Brewer's Hill, which gets about 88 cm of snow yearly. The four-way interlocking panel system keeps snow that does accumulate from entering seams. If you want snow retention for safety, Interlock's optional snow guards install easily without the structural reinforcement that would be needed for slate or concrete tile, letting you choose whether snow stays or slides.

The warranty covers wind speeds up to 120 mph, and Brewer's Hill's typical gusts reach about 96 km/h (60 mph), so you're well within the safety margin. The four-way interlocking system locks panels together in all directions, preventing uplift even during sustained wind events. That engineering is why Interlock's design holds an ICC-ES ESR-1790 evaluation for IBC/IRC code compliance — your roof won't lift or separate when Wisconsin storms hit hardest.

Aluminum cannot rust because it contains no iron — the element that oxidizes and creates rust. Instead, aluminum forms a protective oxide layer that self-heals when scratched, which is why Interlock's panels have been installed from coastal salt-air homes to an Antarctic research station. The Alunar 70% PVDF fluorocarbon finish (applied to both sides) adds 30-year durability against chalking and fading, giving you corrosion protection at multiple levels. In a climate with 822 mm of annual rain, that dual-layer defense means your roof resists moisture damage that would compromise steel or eat through asphalt shingles over time.

No — Interlock's Tile profile weighs about 0.59 lb/sq ft and is roughly 96% lighter than concrete or clay tile, so no structural reinforcement is needed. You can install it directly over most existing roofs, saving thousands in framing work. The Standing Seam and Shake profiles are even lighter at 0.41–0.58 lb/sq ft. This lightweight advantage means retrofitting a Milwaukee County home becomes a straightforward installation without the engineering or construction costs that traditional tile demands, plus you save the weight-bearing strain on your home's structure over decades.

Interlock's UL 2218 Class 4 rating — the highest impact classification available — means your roof handles hailstones up to 1.5 inches without perforation. Many insurers offer discounts for Class 4 rated roofs because the risk of damage is so low. With that documentation in hand, contact your agent about potential premium reductions or increased coverage limits. The warranty itself covers perforation from hail, so you have protection both ways: through your policy and through Interlock's Guardian warranty, giving you confidence during Brewer's Hill's severe weather season.

energy-efficient Interlock colors achieve up to 0.55 initial solar reflectance (measured for aged Copper Penny), reflecting heat that asphalt absorbs and re-radiates into your home. The thermal emissivity rating of 0.84 means the roof sheds absorbed heat effectively. Brewer's Hill receives about 3128 sunshine hours per year — enough to make that reflectance meaningful over a full summer. You won't eliminate air conditioning costs in Wisconsin's moderate climate, but the Cool Roof Rating Council certification shows these panels reduce the heat burden your cooling system must handle compared to dark asphalt.

Installation timeline depends on roof size and weather, but because Interlock panels install over most existing roofs — no costly tear-off required — the labor phase is typically faster than asphalt replacement. You avoid the landfill waste and disruption of stripping old shingles. Interlock Metal Roofing has served the region since 2001, so your local installer understands Milwaukee County's seasonal weather windows. Discuss your specific roof structure during the quote; the lightweight design (Slate at 0.41 lb/sq ft) means most homes qualify for direct overlay installation, keeping your project on schedule and budget.

Aluminum requires far less maintenance than asphalt, wood, or tile. There's no moss growth, no wood rot, no concrete cracking from freeze-thaw cycles — all common problems in Brewer's Hill's 79 annual freeze-thaw days and 822 mm of rain. The Alunar finish is warranted 30 years against chalking and fading, so recoating is unnecessary for decades. Occasional gutter cleaning and inspection after severe winds (gusts near 96 km/h) are standard maintenance for any roof. CALGreen verification confirms the reduced maintenance burden, meaning your real costs stay low over the roof's life.

The Guardian Warranty is a non-prorated lifetime limited warranty for the original owner covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance — no time caps or percentage deductions. If you sell, it transfers once to the next owner with 50 years of remaining coverage from completion date, adding significant resale appeal. That's essentially two generations of protection. The Alunar coating itself carries a separate 30-year warranty against chalking and fading. Combined with aluminum's inherent corrosion immunity, you're buying the last roof you'll install, which makes the upfront cost competitive against replacing asphalt every 15–20 years.

Yes. Brewer’s Hill 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.
