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

Aluminum's smooth, hard surface sheds snow and ice naturally rather than trapping moisture like asphalt does. With about 88 cm of snow annually and roughly 79 freeze-thaw days per year in this region, that matters: ice dams form when heat escapes through the roof, melting snow that then refreezes at the eaves. Metal's low thermal conductivity and reflective energy-efficiency coatings (up to 0.55 solar reflectance) keep roof surface temperatures lower, reducing melt cycles. The four-way interlocking panels also prevent water from pooling at seams, which is critical when temperatures fluctuate around freezing.

No — aluminum has inherent freeze-thaw durability because it contains no iron and cannot rust or rot. Unlike asphalt shingles that crack and curl under 79 annual freeze-thaw cycles, or wood shake that splits as water penetrates and expands, aluminum's oxide layer self-heals when scratched and resists the expansion-contraction stress that destroys other materials. In climates with frequent thawing — Arlington Heights sees gusts up to 96 km/h during rapid pressure-change events — metal's rigidity and lack of moisture absorption make it fundamentally more durable. The Guardian Warranty specifically covers splitting and cracking (conditions that plague freeze-thaw zones), backed by installations from coastal salt-air homes to an Antarctic research station.

Aluminum cannot rust because it contains no iron — the element that oxidizes and corrodes in moisture. Steel roofing requires ongoing protective coatings to prevent rust, especially in climates like Arlington Heights, which receives about 822 mm of rain annually plus 88 cm of snow. Aluminum's oxide layer forms instantly when exposed to air and self-heals when scratched, providing permanent corrosion protection without maintenance. The Alunar 70% PVDF fluorocarbon finish (warranted 30 years against chalking and fading per ASTM standards) adds another layer of durability for wet Wisconsin conditions. Once installed, aluminum roofing never needs repainting to stay protected from moisture.

Yes — Interlock's four-way interlocking panels are warranted to resist wind speeds up to 120 mph when installed to specification, far exceeding typical Wisconsin gusts (average 22 km/h with peaks near 96 km/h). The interlocking design means each panel locks to its neighbors on all four sides, creating a unified structural system that distributes wind loads across the entire roof rather than stressing individual fasteners. This is especially important in Milwaukee County, where rapid pressure changes during spring and fall storms are common. The UL 2218 Class 4 impact rating also ensures the panels won't delaminate or lose integrity under extreme wind-driven hail, which often accompanies high-gust events.

No structural reinforcement is needed. Interlock metal roofing is extraordinarily light — the Mediterranean Tile profile installs at about 0.59 lb/sq ft, roughly 96% lighter than concrete or clay tile. This means it installs directly over most existing roofs without additional framing or engineering. For comparison, traditional tile or slate would require costly structural upgrades; aluminum delivers the same aesthetic without that burden. The lightweight advantage is especially valuable in Wisconsin's climate, where heavy snow loads (about 88 cm annually) are managed by the roof's strength and aerodynamic shape, not by added structural weight. You gain the look of premium materials with the practical simplicity of asphalt-weight installation.

The Guardian is a lifetime limited, non-prorated material warranty for the original owner — meaning there's no declining coverage over time, only the cost of labor if repairs are ever needed. It covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance. The warranty is also transferable once, giving the next owner 50 years of protection from completion, which adds significant value at resale. With Arlington Heights experiencing 79 annual freeze-thaw cycles and roughly 822 mm of rain, having non-prorated coverage for conditions that specifically stress other roofing materials (splitting from freeze-thaw, rot from moisture) provides genuine long-term peace of mind. This is the only roof you'll ever buy.

Possibly. Interlock Metal Roofing achieves UL 2218 Class 4 impact rating — the highest available — and the warranty even covers perforation from hailstones up to 1.5 inches. Some insurers recognize Class 4 ratings and offer premium discounts for non-combustible, impact-resistant roofing. You should contact your agent to ask whether metal roofing qualifies for a reduction; many policies do reward roofs that reduce claims risk. In Wisconsin, where spring storms can produce severe hail, having documented Class 4 performance and a warranty that explicitly covers impact damage gives insurers confidence that your roof will protect your home. Even without a discount, the reduced likelihood of hail damage claims over the roof's lifetime translates to better long-term value.

Yes, particularly with energy-efficient colors. Interlock's reflective coatings deliver thermal emissivity of 0.84 and initial solar reflectance up to 0.55 (measured in Aged Copper Penny), reflecting heat that asphalt absorbs and re-radiates into your home. Arlington Heights receives about 3128 sunshine hours annually; that's significant solar exposure during the cooling season. By lowering roof surface temperatures, reflective metal roofing reduces the heat conducted into your attic and living spaces, which decreases air-conditioning load. The cool-roof benefit is modest in the upper Midwest compared to hot climates, but over a roof's 50+ year lifespan, the cumulative energy savings pay dividends. energy-efficiency certification also qualifies you for certain rebate and tax incentives.

Far less than asphalt, wood, or tile. Aluminum requires no repainting, reshingles, or replacement of rotted/split boards — the oxide layer protects it permanently without upkeep. Unlike asphalt shingles that granulate and curl under freeze-thaw stress (79 cycles annually in Arlington Heights), metal panels maintain their integrity indefinitely. Wood shake splits as moisture and temperature fluctuation stress the grain; tile cracks under impact. Routine maintenance for metal is limited to clearing leaves from gutters and perhaps occasional gentle washing to remove dust. The Alunar fluorocarbon finish is warranted 30 years against chalking and fading, so color-fading is not a maintenance concern. CALGreen verification confirms reduced-maintenance performance, saving you time and cost over decades.

Yes — Interlock's light weight (0.41–0.59 lb/sq ft depending on profile) allows direct installation over most existing asphalt or wood shingles without tear-off. This saves labor, landfill costs, and installation time. Typical residential roofs install in 2–5 days depending on size, pitch, and weather. Since no structural reinforcement is required, the process is straightforward: the old roof stays in place as an air gap, the metal panels are laid in rows, and the four-way interlocking system locks each panel to its neighbors. This overlap design also improves wind resistance and hail protection. Installation over an existing roof is not only faster and cheaper than a traditional tear-off-and-reinstall, it's often code-compliant under ICC-ES ESR-1790 (reissued 2025). Your local Interlock installer can assess your specific roof and timeline on a consultation.
