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

Interlock's four-way interlocked aluminum panels shed snow and ice effectively without pooling water underneath. Hazel Crest receives about 68 cm of snow annually and experiences roughly 70 freeze-thaw cycles per year — conditions that crack asphalt shingles and trap ice. The smooth, slippery surface of aluminum allows snow to release before it bonds, and the interlocking design prevents water seepage during thaw cycles. You can add snow guards to control sliding on steep pitches if desired.

No — aluminum is immune to the damage that freeze-thaw cycling inflicts on asphalt and wood. Hazel Crest experiences about 70 freeze-thaw days annually, paired with roughly 1042 mm of rainfall. Asphalt absorbs moisture, expands when it freezes, and cracks as it thaws; aluminum cannot absorb water and its oxide layer self-heals when scratched. The material's flexibility also prevents the brittle failure seen in slate or concrete tile under repeated temperature swings.

Aluminum cannot rust because it contains no iron; steel roofs rust within years in wet climates like Hazel Crest's (1042 mm annual rain, 68 cm snow). Interlock uses roofing-grade 3105-H24 / 3003-H24 aluminum alloy with a Alunar 70% PVDF fluorocarbon coating on both sides for extra protection. When the coating is scratched, aluminum's oxide layer forms automatically and re-heals — a natural process steel cannot perform. This dual defense means the roof stays intact through decades of moisture exposure.

Most homes need no reinforcement. Interlock's aluminum panels are extraordinarily light — the Mediterranean Tile profile installs at just 0.59 lb/sq ft, about 96% lighter than concrete or clay tile. Since the panels weigh less than the asphalt roof already on your house, installation typically occurs directly over your existing roof. The light weight also means lower installation costs and no expensive structural engineering. Your home already carries this load safely.

Yes — the four-way interlocking system holds the roof even during extreme gusts. Hazel Crest's typical daily winds reach about 25 km/h with gusts to 93 km/h; Interlock's panels are warranted to resist sustained wind speeds up to 120 mph (193 km/h) when installed to specification. The interlocking design — not fasteners alone — distributes wind load across the entire roof surface. Proper installation by a qualified contractor ensures the panels remain locked even in severe storms.

Interlock panels carry a UL 2218 Class 4 impact rating, the highest available, and the warranty even covers perforation from hailstones up to 1.5 inches. This durability may qualify you for an insurance discount on comprehensive (hail and weather) coverage — check with your agent. Class 4 protection means the roof resists impacts that dent or crack asphalt, wood, and tile. Many insurers recognize this and reward owners with lower premiums over the roof's 50+ year life.

Yes — energy-efficient Interlock colors reflect heat rather than absorb it. Aged Copper Penny achieves initial solar reflectance up to 0.55 and thermal emissivity of 0.84, meaning it bounces sunlight away and re-emits absorbed heat before it penetrates your attic. Hazel Crest enjoys about 3025 sunshine hours per year. While winter heating dominates your climate, reflective coatings still reduce peak summer cooling loads. Cool Roof Rating Council rating confirms measurable energy savings versus asphalt, which absorbs solar energy and raises interior temperatures.

Virtually none compared to asphalt, wood, or tile. Interlock aluminum requires no re-sealing, patching, or replacement of damaged sections — asphalt shingles fail regularly in Hazel Crest's 70 freeze-thaw days per year. No algae or mold grows on aluminum as it does on asphalt in wet climates receiving 1042 mm annual rain. Gutters need cleaning like any roof, but the panels themselves remain maintenance-free. This durability is why the warranty is non-prorated for the original owner and transferable for 50 years beyond that.

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. The coating is separately warranted 30 years against chalking and fading (ASTM D4214 / D2244 measured). Critically, the warranty transfers once to the next owner for 50 years from completion. This transferability adds real resale value — the next buyer inherits decades of protection. No other roofing material offers this combination of owner benefit and timeline.

Yes — aluminum is approximately 95% recyclable, while asphalt shingles end up in landfills. Interlock, manufactured since 1998 in Delta, BC, eliminates the tear-off-to-landfill cycle entirely. When your roof eventually reaches end-of-life (50+ years from now), the aluminum panels retain value as scrap metal. Asphalt roofs, by contrast, generate thousands of pounds of waste per home. Hazel Crest's 1042 mm annual rainfall also means you're capturing clean water runoff from an inert aluminum surface rather than chemical-laden asphalt granules.
