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

Yes—aluminum actually thrives in freeze-thaw conditions. With about 82 freeze-thaw days per year in your area, material brittleness matters, and aluminum doesn't crack or become brittle when wet then frozen. The roofing-grade 3105-H24 and 3003-H24 aluminum alloy used in Interlock panels maintains flexibility across temperature swings. Asphalt shingles, by contrast, harden and crack under repeated freezing. Your roof experiences roughly 1 meter of snow annually, and that melt-refreeze cycle is exactly where aluminum's non-corrosive oxide layer and consistent material properties pay off—no splitting, no delamination, just reliable performance year after year.

The four-way interlocking system locks snow in place and prevents the sliding that damages gutters and creates hazardous ground-level avalanches. Lombard receives roughly 73 cm of snow annually, and Interlock's lightweight design—the Shingle profile weighs just 0.41 lb/sq ft—allows proper ventilation that reduces ice-dam formation compared to solid materials. The smooth, sloped panel design also encourages melt-off during the 3,051 sunshine hours you get each year. Optional snow guards can be installed for architectural standing seams in areas where you want extra control. The warranty covers wind speeds up to 120 mph, protecting against the ice-plus-wind loading that stresses roofs after heavy snow.

Aluminum cannot rust because it contains no iron—it's chemically impossible. In DuPage County's ~993 mm of annual rainfall, traditional steel roofing will corrode from the inside out; aluminum develops a self-healing oxide layer that actually protects the metal underneath. The Alunar 70% PVDF fluorocarbon finish—applied to both sides of every panel—adds a 30-year warranty against chalking and fading. This dual-layer protection matters in transitional climates like yours, where rain mixes with snow and seasonal temperature swings create moisture stress. You're buying a roof that won't deteriorate from oxidation, not one you're hoping holds long enough to recoup the install cost.

Interlock metal roofing is warranted to resist sustained winds up to 120 mph and is built specifically for gust-prone regions. Lombard experiences typical daily winds around 19 km/h with gusts reaching 97 km/h—the four-way interlocking aluminum panels lock together so tightly that uplift and flutter aren't risks. Each panel's mechanical seams and the interlocking geometry distribute lateral and vertical force across the entire roof system instead of concentrating stress on fasteners like asphalt shingles do. The ICC-ES evaluation report ESR-1790 covers wind performance under IBC/IRC codes. You won't see panels flapping or pulling free; the system is engineered to move as one continuous unit.

No—Interlock metal roofing carries a UL 2218 Class 4 impact rating, the highest available, and the Guardian warranty even covers perforation from hailstones up to 1.5 inches. Asphalt shingles fail under Class 3 hail; you're jumping two full categories in durability. Many insurance underwriters recognize this and offer discounts for Class 4 roofing—you'll want to request a quote before installation, then notify your agent after completion with the certification documentation. In Illinois's severe weather patterns, a single hail event can trigger a full roof replacement on shingles; with aluminum, you're covered and building equity instead of filing claims.

Almost never. Interlock's Mediterranean Tile profile—which captures the aesthetic of heavy clay or concrete tile—weighs just 0.59 lb/sq ft, roughly 96% lighter than the real thing. This extraordinary lightness means you can install Interlock over your existing roof in most cases without structural work or engineering reports. Asphalt shingles sit at around 2–4 lb/sq ft; aluminum at a fraction of that. Your home's frame was built to handle roof loads—switching to metal actually reduces that load. The material's light weight also reduces installation complexity, labor time, and cost compared to premium roofing materials that demand rafter reinforcement and structural assessment.

Very little. Twice yearly, rinse debris from gutters and valleys—that's it. Asphalt shingles require inspections for deterioration and curling, lose granules that clog gutters, and crack under Lombard's 82 annual freeze-thaw cycles. Shake and cedar roofing demand regular treatment against rot and splitting. Interlock aluminum won't rot, split, curl, or deteriorate. The Alunar finish is warranted 30 years against fading and chalking per ASTM testing standards; it won't flake or lose color. CALGreen verification documents the reduced maintenance burden. Your time goes toward the house, not the roof—and insurance or resale inspectors will note the material's durability, not mark it for repairs.

Yes, when you calculate lifetime cost. Asphalt lasts 15–20 years in Illinois's freeze-thaw environment—you'll replace it twice before Interlock needs its first replacement. Add labor, tear-off waste disposal, and two decades of repairs, and asphalt costs more over 50 years. Interlock carries a lifetime limited, non-prorated material warranty for the original owner and a one-time 50-year transferable term for the next owner, meaning zero roof replacement during your ownership and a major selling point when you move. Energy savings from energy-efficient colors, insurance discounts from Class 4 hail rating, and zero maintenance labor add up quickly. This is the last roof you buy—that certainty carries real financial value.

Yes. energy-efficient Interlock colors have thermal emissivity up to 0.84 and initial solar reflectance reaching 0.55 (Aged Copper Penny)—meaning they bounce heat back into the sky instead of absorbing it like asphalt does. Lombard gets approximately 3,051 hours of sunshine yearly; that's thousands of hours where reflectance saves cooling load. Asphalt shingles absorb solar radiation and transfer heat into your attic; metal stops it at the surface. Cool Roof Rating Council certification backs the performance data. In summer, the difference is measurable on your electric bill; in winter, a properly ventilated metal roof doesn't trap heat loss, so you're not paying an energy penalty. It's passive efficiency—the physics work for you every clear day.

Yes. Asphalt shingles end up in landfills by the millions of tons each year after 15–20 year lifespans; your Illinois roof will be replaced at least twice. Interlock aluminum is approximately 95% recyclable and designed to last 50+ years, breaking the tear-off-to-landfill cycle entirely. When it does eventually leave your roof, the material returns to the recycling stream—aluminum's value means it gets reclaimed, not buried. Manufactured since 1998 in Delta, BC, and installed from coastal salt-air homes to Antarctic research stations, the product's durability track record is real, not marketing. Choosing aluminum means one installation, one lifetime of protection, and zero asphalt waste from your home.

Yes. Lombard averages about 73 cm of snow, 993 mm of rain, roughly 82 freeze–thaw days a year, with peak wind gusts near 97 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.
