Metal Roofing in Boone Township, Illinois — Lifetime Interlock® Aluminum Shingles Installed Locally

Aluminum's smooth, hard surface sheds snow and ice far more effectively than asphalt, reducing ice dam risk during the region's approximately 83 freeze-thaw days per year. The four-way interlocking panels are warranted to resist wind gusts up to 120 mph, so snow and ice loads stay secure. Unlike asphalt, which becomes brittle in cold snaps and expands when warmed by the about 3,084 sunshine hours annually, aluminum's thermal cycling tolerance means it won't crack or cup as temperatures swing.

No. Aluminum has no iron content — it cannot rust or rot, even after decades of Boone County's roughly 84 freeze-thaw cycles yearly. The oxide layer on the surface actually self-heals when scratched, so freeze-thaw stress that splinters wood or cracks ceramic tile simply doesn't affect aluminum. The Alunar 70% PVDF coating is warranted 30 years against chalk and fade (ASTM D4214), meaning the finish stays intact through endless freeze-thaw swings.

Aluminum cannot rust because it contains no iron. When exposed to Boone Township's about 838 mm annual rainfall, aluminum naturally forms a self-healing oxide layer that protects the underlying metal — a process that repeats infinitely. Steel roofs, by contrast, rust within years in wet climates. Interlock's 3105-H24 and 3003-H24 aluminum alloy (ASTM B209) is the same material used in coastal salt-air homes and Antarctic research stations, designed to withstand far harsher moisture exposure than central Illinois receives.

Yes. The four-way interlocking panels lock together so tightly that they're warranted to resist sustained winds up to 120 mph. Boone County's typical gusts around 100 km/h (62 mph) are well within safe limits, and the interlocking design distributes lateral force across the entire roof rather than stressing individual fasteners. This design has proven reliable in regions with severe wind events far stronger than what the area typically experiences.

Interlock metal roofing carries a UL 2218 Class 4 impact rating — the highest available — and the warranty even covers perforation from hailstones up to 1.5 inches. Many insurers recognize this highest rating and offer premium discounts on metal roofs because the material genuinely resists damage that destroys asphalt. Ask your agent about discounts; the upfront savings, combined with the roof's 50-year transferable warranty, make the long-term economics compelling.

No. The Interlock Slate installs at just 0.41 lb/sq ft, and even the heavier Mediterranean Tile profile weighs only about 0.59 lb/sq ft — roughly 96% lighter than concrete or clay tile. Most Boone Township homes can support metal roofing without any frame upgrades. The lightweight design also allows installation directly over an existing asphalt roof, avoiding costly tear-off labor and landfill fees.

Metal roofing costs more initially but is the last roof you'll buy. Asphalt typically lasts 15–20 years and requires replacement twice in a metal roof's lifetime. Interlock's Guardian Warranty is lifetime limited non-prorated for the original owner and transferable for 50 years to the next owner, so resale appeal and future savings are built in. Over 50+ years, aluminum eliminates repeated tear-off, disposal, and reinstallation costs that drain asphalt budgets.

Very little. Unlike asphalt, which requires periodic sealing, wood shakes that split and rot, or tile that cracks, aluminum doesn't degrade. Boone Township's about 838 mm annual rainfall naturally cleans the surface. The Alunar coating is CALGreen-verified for reduced maintenance. You'll never replace missing shingles, reseal seams, or scrape moss — just occasional gutter cleaning, the same task any roof requires.

Yes, energy-efficient colors reduce cooling load. Interlock's reflective finishes achieve thermal emissivity up to 0.84 and solar reflectance up to 0.55, meaning they bounce heat away rather than absorbing it like asphalt. In a region with about 3,084 annual sunshine hours, this reflectance compounds over time — less heat absorbed means lower air-conditioning demand on warm days. The Cool Roof Rating Council certification quantifies this advantage, and the energy savings accrue over the roof's lifetime.

Yes. Boone Township averages about 84 cm of snow, 838 mm of rain, roughly 83 freeze–thaw days a year, with peak wind gusts near 100 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.
