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

Interlock's four-way interlocking aluminum panels shed snow and ice efficiently because the smooth, hard surface resists ice damming — the slipperiness that prevents water pooling at the eaves. Hubertus averages about 79 freeze-thaw cycles annually, a condition that cracks asphalt shingles and wood shakes by repeatedly expanding and contracting the roof material. Aluminum's oxide layer remains flexible through these temperature swings without degrading. You can add snow guards to any profile if you prefer controlled release in heavy snow years.

Freeze-thaw damage occurs because water enters porous materials (wood, asphalt, concrete), then expands when frozen, cracking the material from inside. Aluminum doesn't absorb water — it's inherently waterproof, so freeze-thaw cycles can't crack or warp it. With about 79 freeze-thaw days per year in your region and roughly 880 mm of annual precipitation, the durability advantage compounds over decades. Interlock panels maintain their structural integrity because the material itself changes state, not the roof.

Aluminum cannot rust because it contains no iron — rust is iron oxide, and there's no iron to oxidize. Instead, aluminum develops an invisible oxide layer that self-heals when scratched or abraded, automatically re-sealing small damage. Interlock panels use roofing-grade 3105-H24 and 3003-H24 aluminum alloy per ASTM B209, coated with Alunar 70% PVDF fluorocarbon finish on both sides for extra protection in damp conditions. With Hubertus receiving about 880 mm of rain annually, corrosion resistance matters — your roof won't degrade from moisture exposure the way steel or wood does.

Interlock panels carry UL 2218 Class 4 impact rating — the highest available — and the Guardian Warranty covers perforation from hailstones up to 1.5 inches. Wisconsin experiences hail risk, and Class 4 resistance often qualifies homeowners for insurance premium reductions because repairs and replacements cost insurers far less. Check with your agent about discounts; many carriers reward non-combustible, impact-rated roofing. The hard aluminum surface distributes impact force better than asphalt or wood, reducing dent risk even in severe storms.

No structural reinforcement is necessary because Interlock panels are extraordinarily light — the Slate profile installs at about 0.41 lb per square foot, and even the heaviest Mediterranean Tile profile at 0.59 lb/sq ft is roughly 96% lighter than concrete or clay tile. This means installation over most existing roofs is possible, saving tens of thousands in labor and disposal costs. Your home's framing was designed to carry asphalt shingles and their weight; Interlock panels place minimal additional load, whether installing new or overlay.

Four-way interlocking means each panel locks to its neighbors on all four sides — left, right, top, and bottom — creating a unified system that resists uplift even in severe gusts. The warranty guarantees 120 mph wind resistance when installed to specification. Hubertus experiences typical daily-max winds around 22 km/h with gusts reaching 96 km/h; the interlock system's redundant connections handle these regularly, and the warranty covers extreme events. Individual fasteners alone can't compete with the shear strength of four continuous mechanical locks.

energy-efficient Interlock colors achieve initial solar reflectance up to 0.55 and thermal emissivity of 0.84, meaning the roof reflects sunlight rather than absorbing heat the way asphalt shingles do. Hubertus receives about 3,128 hours of sunshine per year; over a long summer or unusually warm spring, this reflectance measurably reduces attic temperature and cooling load. The Cool Roof Rating Council rating validates this performance independently. Reflective roofing cuts peak summer temperatures by 20–30°F compared to dark asphalt, lowering air-conditioning runtime and electrical bills.

Interlock panels require virtually no maintenance — no annual inspections for cracked shingles, no moss or algae treatment, no re-coating or sealing. Asphalt shingles demand inspection every 2–3 years and typically fail around year 15–20 in Wisconsin's 79 annual freeze-thaw cycles. Wood shakes split and rot from moisture and temperature swings. Aluminum doesn't degrade from weather exposure; the Alunar 70% PVDF coating is warranted 30 years against chalking and fading. Rinse debris occasionally; that's it. CALGreen verification confirms reduced maintenance compared to traditional materials.

The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance — essentially every way a roof fails. It's one-time transferable, giving the next owner 50 years of coverage from completion date. No prorating means you pay nothing at year 30 or year 50 if a covered failure occurs. In a climate with 79 freeze-thaw cycles and 880 mm annual rain, this covers the exact conditions that destroy asphalt and wood. You're buying the last roof you'll install.

Interlock Metal Roofing, the manufacturer and local installer, has served the region since 2001 and has installed panels from coastal salt-air homes to an Antarctic research station. That range of experience — extreme salt corrosion to extreme cold — means your Washington County home receives installation from installers who've solved every environmental challenge. The company manufactures in Delta, BC, since 1998, so technical support and parts availability are direct. When a local installer is also the manufacturer, accountability is built in.

Yes. Hubertus 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.
