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

Yes—aluminum thrives in freeze-thaw climates. DuPage County experiences about 82 freeze-thaw days per year, and aluminum's oxide layer self-heals when scratched, so it won't degrade from repeated temperature swings like asphalt or wood does. The material expands and contracts uniformly with no risk of cracking, splitting, or curling. Roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209) is engineered for exactly these conditions. Paired with the ICC-ES ESR-1790 evaluation (reissued 2025 for current code), an Interlock roof handles Bartlett winters without the degradation that shortens asphalt shingle life.

Metal roofing handles heavy snow exceptionally well. Bartlett averages about 73 centimeters of snow annually, and the four-way interlocking aluminum panels are engineered to shed snow safely while the light weight—the Shake profile installs at roughly 0.58 lb/sq ft—means no structural reinforcement is needed, even over existing roofs. The smooth, slippery surface naturally encourages snow movement, and optional snow guards can be installed where local building codes or homeowner preference calls for it. Unlike asphalt, which absorbs weight and can sag under heavy wet snow, aluminum maintains its shape season after season.

Absolutely. The four-way interlocking panels are warranted to resist wind speeds up to 120 mph (193 km/h), and Bartlett's typical gusts reach about 97 km/h—well within rated performance. The interlocking design prevents uplift: each panel engages its neighbors on all four sides, so wind cannot get under the edges and peel the roof away. This isn't bolted-down standing seam or nailed shingles; the mechanical lock is continuous. Combine that with proper installation to ICC-ES ESR-1790 spec, and you're protected through typical DuPage weather events and beyond.

Hail is unlikely to be a financial problem. 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. Many insurers recognize this durability and offer premium discounts for Class 4-rated roofs, which can offset installation cost over time. Asphalt shingles, by contrast, are vulnerable to hail denting and algae growth after impact, shortening their life. An aluminum roof gives you actual impact resistance, not just repair bills.

Aluminum cannot rust because it contains no iron—iron is the element that oxidizes and causes rust. Instead, aluminum forms a thin, invisible oxide layer the instant it's exposed to air, and that layer self-heals when scratched or damaged. Interlock panels use roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209), topped with a Alunar 70% PVDF fluorocarbon finish applied to both sides for extra protection. In DuPage County's wet climate (~993 mm rain, ~73 cm snow annually), this means your roof will never develop rust stains, corrosion holes, or the structural decay that steals decades from a steel roof's life.

Your house already supports metal roofing—no structural work needed. The Mediterranean Tile profile, despite looking like heavy clay or concrete tile, weighs only about 0.59 lb/sq ft—roughly 96% lighter than the real thing. Even heavier wood shake homes (0.58 lb/sq ft) install directly over existing roofs without reinforcement. Most houses are framed to handle asphalt shingles, and metal roofing weighs the same or less, so you avoid the $5,000–$15,000 structural upgrades that traditional tile requires. This also means faster installation and no disruption to your home's foundation or frame.

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—all the ways roofs actually fail. It's also one-time transferable, giving the next owner 50 years of coverage from completion. In practice, roofing-grade aluminum with a 30-year Alunar PVDF coating (ASTM D4214 / D2244 tested) lasts 50+ years in climates like Bartlett's because freeze-thaw cycles, hail, and rain don't degrade the material the way they do asphalt. You're buying your last roof, not planning a replacement in 15–20 years.

Yes. energy-efficient Interlock colors have a thermal emissivity of 0.84 and solar reflectance up to 0.55 (Aged Copper Penny profile), meaning they bounce heat back into the sky instead of absorbing it like asphalt does. Over Bartlett's ~3,051 annual sunshine hours, that reflection adds up to lower attic temperatures and reduced air-conditioning load. The Cool Roof Rating Council rating confirms measurable energy savings. Light colors perform best, but even mid-tone options reflect more heat than traditional asphalt. For homeowners focused on utility bills or carbon footprint, the energy savings often contribute to long-term cost recovery.

Almost none. Aluminum won't rot, split, curl, or grow algae and moss the way asphalt and wood do, so you skip the debris cleaning, moss treatments, and seal coatings that traditional roofs demand every few years. Occasional rinses in dusty conditions keep it looking new, but that's optional. The system is CALGreen-verified for reduced maintenance, meaning building codes recognize it as a low-upkeep alternative. Over Bartlett's ~993 mm of annual rainfall and ~82 freeze-thaw days, asphalt shingles require routine inspection and repair; aluminum just sits there, year after year, without degrading.
