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

Yes — aluminum doesn't crack, curl, or split when water freezes and thaws. DeKalb County experiences about 81 freeze-thaw cycles per year, and that repeated expansion-contraction is what breaks down asphalt shingles and wood shakes. Aluminum's oxide layer doesn't degrade in those temperature swings, and the material won't absorb water the way asphalt does. The Alunar fluorocarbon finish (warranted 30 years against breakdown) adds a second layer of protection against the salt and moisture that winter weather brings. One roof, installed right, lasts through decades of Illinois winters.

Metal roofing sheds snow and ice far more reliably than asphalt because its smooth, tight-seamed surface prevents the moisture absorption that leads to ice dams. With about 71 cm of snow falling annually in DeKalb County, that matters. The four-way interlocking aluminum panels create a unified surface — no gaps where ice can wedge and lock. Snow slides cleanly during thaw cycles. If needed, snow guards can be installed to control slides on steep pitches. The roofing-grade 3105-H24 aluminum alloy won't degrade under the repeated freeze cycles and salt exposure typical of Illinois winters, unlike steel roofing, which would rust.

Most homes need no structural reinforcement. Interlock's metal tile profile, for example, weighs about 0.59 lb/sq ft — roughly 96% lighter than concrete or clay tile. Even the heavier Shake profile comes in around 0.58 lb/sq ft, while Slate is just 0.41 lb/sq ft. A typical asphalt shingle roof weighs more. Because metal panels are so light, they install directly over most existing roofs without tearing off or adding support. Your framing sees less load, not more. This also cuts installation time and disposal costs. A structural engineer only steps in if your home already has known frame issues — which would need attention regardless of roofing material.

No. Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph when installed to spec. DeKalb County's typical gusts reach about 98 km/h (61 mph), well within that margin. The mechanical interlock between panels means there's no single point of failure — wind pressure that would lift shingles simply tightens the seams. Installation matters: clips and fasteners must be placed in the field, not the seams, to work with the interlocking system. A properly installed Interlock roof won't fail in the gusts you'll see here. Insurance companies recognize this durability, and some offer premium discounts for metal roofs because the claims history is so much lower than asphalt.

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. Most hail events in Illinois fall well short of that threshold. Unlike asphalt, which cracks and loses granules in moderate hail, aluminum panels dent minimally and retain full functionality. Many insurers recognize this and offer rate discounts for Class 4 metal roofs because loss history is significantly lower. A roof that won't fail in hail, won't leak, and carries a non-prorated lifetime material warranty is a genuine risk reduction for your home. Check your policy; some companies explicitly list metal roofing as a discount-eligible upgrade.

The Guardian Warranty is a non-prorated lifetime limited warranty for the original owner on material defects — rusting, rotting, splitting, cracking, curling, and loss of impact resistance. When you sell, the next owner gets 50 years from installation date. That's a concrete promise backed by Interlock's 25+ years of field data since 1998. An asphalt roof typically needs replacement every 15–20 years; a metal roof routinely lasts 50+ years with minimal maintenance. The Alunar fluorocarbon finish itself carries a separate 30-year warranty against chalking and fading. Over a typical 30-year ownership period, a metal roof will be your last roof; asphalt will be your second or third.

Metal roofing with energy-efficient colors reflects heat instead of absorbing it the way asphalt does. Interlock's reflective finishes achieve thermal emissivity of 0.84 and initial solar reflectance up to 0.55, meaning less heat transfers into your attic and HVAC system. With about 3087 sunshine hours per year in DeKalb County, that reflection compounds. You won't eliminate cooling costs, but measured studies show reflective metal roofs reduce cooling load by 10–20% compared to dark asphalt — enough to offset a portion of your summer bills. The benefit is greater if your home has poor attic ventilation or if you're in a high-cooling climate. Combined with the roof's 50+ year lifespan, energy savings add up.

Metal requires far less: no seasonal inspections for curling or missing shingles, no moss cleaning, no wood-rot concerns. Asphalt roofs need inspections every 2–3 years and spot repairs starting around year 5. Wood shakes require annual cleaning and periodic replacement of rotted boards. Interlock metal roofing is CALGreen-verified for reduced maintenance. Twice a decade, flush leaves and debris from the gutters and valleys — the same task any roof requires. The interlocking panels shed water immediately; water doesn't pool or sit, so algae growth and mold are minimal. The Alunar finish doesn't degrade in DeKalb County's 853 mm of annual rain. Over a 50-year lifespan, the time and money saved on maintenance easily pays for the initial install.

Installation typically takes 3–7 days depending on roof size and complexity; most single-family homes complete in under a week. Because Interlock panels are exceptionally light — Slate at just 0.41 lb/sq ft — most roofs install directly over the existing asphalt without tear-off. Your old roof becomes the underlayment, saving weeks of debris removal and landfill costs. New underlayment and metal panels go on top. Interlock Metal Roofing has served this region since 2001 and knows Franklin Township's building department, roof pitch variations, and local weather patterns. The installer will walk you through the timeline when measuring your home. Over-roof installation also adds an air gap that improves insulation, a side benefit to skipping the tear-off.

Yes. Aluminum is approximately 95% recyclable and retains its properties through infinite recycling cycles. When an Interlock roof reaches end-of-life (which takes 50+ years), the panels are melted and reused for new roofing, siding, automotive parts, or structural aluminum — not landfilled. Asphalt shingles, by contrast, are tear-off waste destined for landfills; millions of tons accumulate annually because they can't be recycled. DeKalb County's 853 mm of annual rainfall means water runoff and roof longevity matter: a 50-year metal roof generates one installation event, while asphalt generates three or four tear-off-and-haul cycles over the same period. The environmental footprint — measured in landfill volume and installation carbon — is dramatically lower for aluminum. Choosing metal removes asphalt from the waste stream and closes the recycling loop.

Yes. Franklin Township averages about 71 cm of snow, 853 mm of rain, roughly 81 freeze–thaw days a year, with peak wind gusts near 98 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.
