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

Aluminum's slippery surface naturally sheds snow and ice better than asphalt, reducing ice dam buildup during Burke's typical 89 cm annual snowfall and 84 freeze-thaw days. The four-way interlocking panels stay watertight through repeated expansion and contraction—aluminum expands less than steel and doesn't crack or split. Interlock's lightweight design (0.41–0.59 lb/sq ft) means no structural upgrades, and you can add snow guards if desired. The material's durability through extreme temperature swings has been proven in installations from coastal zones to Antarctica.

Aluminum is non-porous and doesn't absorb water, so ice formation inside the material—the main culprit in freeze-thaw failure—never happens. With about 84 freeze-thaw cycles per year in Burke and roughly 781 mm of rain, water simply runs off rather than lodging in the substrate. Steel rusts when moisture enters microscopic pores; aluminum's oxide layer self-heals when scratched and contains no iron to corrode. The Alunar 70% PVDF coating adds a second defense layer, warranted 30 years against chalking and fading.

No, aluminum cannot rust because it contains no iron—rust requires iron oxidation. Burke's annual rainfall of 781 mm and typical wind gusts to 104 km/h expose roofs to constant moisture, where steel would form rust stains and structural weakening. Aluminum develops a thin, self-healing oxide layer that actually protects it from further corrosion. The Alunar 70% PVDF fluorocarbon finish, applied to both sides per ICC-ES ESR-1790 specs, adds extra durability in wet climates. This is why Interlock panels perform identically in salt-air coastal homes and inland regions.

No. Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h), well above Burke's typical wind gusts of 104 km/h. The panels interlock on all four edges, distributing wind load across the entire roof rather than relying on fasteners alone. This engineering is proven in the ICC-ES evaluation report ESR-1790 (IBC/IRC compliant). Proper installation per spec ensures that seasonal gales in Dane County won't compromise the seal or panel attachment. The system has been field-tested from coastal storms to mountain exposures.

No reinforcement is needed. The Interlock Tile profile weighs only about 0.59 lb/sq ft—roughly 96% lighter than concrete or clay tile—so it installs directly over most existing roofs without structural upgrades. Burke homes built to standard code easily support this load, which is also far lighter than asphalt shingles on older structures. The Slate and Cedar Shingle profiles are even lighter at 0.41 lb/sq ft. This weight advantage means no costly framing work, faster installation, and peace of mind that your home's structural integrity remains unchanged.

Interlock aluminum achieves the highest hail impact rating available: UL 2218 Class 4, rated for hailstones up to 1.5 inches. The warranty explicitly covers perforation from hail. Burke receives about 781 mm of annual rainfall, and while severe hail is less frequent in Dane County than in plains states, the Class 4 rating provides absolute protection when it occurs. Some insurers offer premium discounts for Class 4 roofing. Aluminum's non-combustibility (Class A fire rating available) and impact resistance may also lower your overall policy cost—ask your agent about Interlock's ICC-ES certification and UL listing.

Metal roofs cost more upfront but deliver lower total cost of ownership over their lifespan. While asphalt shingles cost less initially, they require replacement every 15–25 years, meaning Burke homeowners typically buy three asphalt roofs in the time Interlock lasts. Add repair costs, maintenance labor, and landfill disposal for old shingles, and asphalt becomes expensive. Interlock's lifetime limited, non-prorated material warranty covers rusting, rotting, splitting, cracking, and curling—eliminating surprise failures. The one-time transferable warranty (50 years to the next owner) also protects resale value. Calculate the total cost per year of roof life, not the sticker price.

Routine maintenance is minimal: occasional gutter cleaning and removal of heavy debris. Unlike asphalt, which sheds granules and requires replacement, or wood shake, which splits and rots, aluminum requires no resealing, re-coating, or structural repairs. Burke's 89 cm annual snowfall and 3089 sunshine hours won't degrade the Alunar 70% PVDF coating, warranted 30 years against fading and chalking. Inspect gutters twice yearly and clear leaves. That's it. The CALGreen-verified low-maintenance profile means you avoid the recurring costs and labor that asphalt and tile demand, freeing your budget for other priorities.

Yes, especially with energy-efficient colors. Interlock's reflective coatings achieve initial solar reflectance up to 0.55 (Aged Copper Penny) and thermal emissivity of 0.84, rated by the Cool Roof Rating Council. These properties reflect solar heat that asphalt absorbs and re-radiates into your home. Burke receives about 3089 sunshine hours per year; summer cooling benefits compound over time. While Wisconsin winters are long and heating dominates, reflective metal roofs still lower air-conditioning costs on warm days and reduce the cooling load during spring and fall. The energy performance is documented on the published solar-reflectance listing —no guesswork.

Installation typically takes 2–5 days for a standard residential roof, depending on size and complexity. Yes, Interlock installs directly over existing asphalt shingles without removal, saving labor and landfill disposal costs. The lightweight design (0.41–0.59 lb/sq ft) means your home's structure supports the new roof without upgrades. A solid deck and underlayment keep the roof asphalt-quiet during Burke's 781 mm annual rainfall—metal roofs aren't loud when properly installed. Interlock Metal Roofing has served the region since 2001 and knows Dane County's code requirements and weather challenges, ensuring quick, reliable installation from permit to final inspection.

Yes. Burke averages about 89 cm of snow, 781 mm of rain, roughly 84 freeze–thaw days a year, with peak wind gusts near 104 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.
