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

Interlock's four-way interlocking panels shed snow and ice far more effectively than asphalt, which traps moisture and increases ice dam risk during Lincolnshire's typical 73 cm of annual snowfall and 82 freeze-thaw cycles. The smooth, hard aluminum surface resists the freeze-thaw expansion that fractures asphalt and wood shingles. Optional snow guards can be installed if you want to control where snow melts off, and the lightweight design (the Slate profile at just 0.41 lb/sq ft) means your structure won't strain even after heavy accumulation.

Asphalt and wood absorb water, then expand and contract as temperatures cycle through freezing—Lincolnshire averages 82 freeze-thaw days yearly. This repeated stress causes cracking, curling, and rot. Interlock's aluminum panels contain no iron and cannot rust; the Alunar coating (30-year warranty against chalking and fading) bonds to both sides of the panel, keeping moisture out entirely. The rigid, non-porous material simply doesn't expand or contract with temperature swings the way vulnerable materials do.

Interlock panels are made from roofing-grade 3105-H24 aluminum alloy (ASTM B209), which contains zero iron—the element that causes rust. Aluminum naturally forms a self-healing oxide layer that stops corrosion before it starts, even in salty or coastal air. With Lake County's ~993 mm of annual rainfall, moisture exposure is constant, but the aluminum won't degrade. The Alunar 70% PVDF fluorocarbon finish, applied to both sides, adds another three decades of protection against the elements. This is why Interlock panels installed since 1998 are still protecting homes from coastal salt spray to Antarctic research stations.

Interlock carries a UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty covers perforation from hailstones up to 1.5 inches. This superior hail performance often qualifies homeowners for insurance discounts; contact your agent with the UL rating and ESR-1790 evaluation report. In Lincolnshire's climate of frequent wind gusts up to 97 km/h and heavy rain, the durability of a non-combustible aluminum roof translates to lower claims risk and improved insurability compared to asphalt.

Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification—far exceeding Lincolnshire's typical peak gusts of 97 km/h. The interlocking seams create a unified system that distributes wind load across the entire roof rather than letting individual shingles lift or tear. This engineered approach, validated in the ICC-ES ESR-1790 evaluation report, means you're protected not just for today's weather but for the extreme gusts that occasionally pass through Lake County.

No structural reinforcement is needed. Interlock's Slate profile installs at just 0.41 lb/sq ft—so light that the Mediterranean Tile profile, despite replicating heavy stone, weighs about 96% less than real concrete or clay tile. Most existing roofs can support the installation without modification, and you can often install Interlock directly over your current asphalt shingles, saving labor and landfill waste. This lightweight advantage is especially valuable in Lincolnshire, where 73 cm of annual snow combined with rainfall means you want a roof system that reduces structural stress, not adds it.

Compared to asphalt (which degrades from UV and cracking), wood shakes (which split and rot), or clay tile (which requires periodic resealing and repair), Interlock panels need only occasional debris removal and a gentle rinse during Lincolnshire's ~993 mm of annual rainfall. The Alunar coating protects both sides of the panel with a 30-year warranty against fading and chalking, so no recoating is required. The non-porous aluminum eliminates the mold and moisture issues that plague asphalt in high-humidity or freeze-thaw climates. You're looking at one last roof purchase, not decades of repair bills.

Asphalt typically lasts 15–20 years, meaning you'll replace it twice during Interlock's lifespan. The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner (50 years for the next owner), so you buy once and never tear off and landfill roofing again. Factor in the cost of two asphalt replacements, plus insurance discounts for Class 4 hail rating, plus no maintenance, plus energy savings from energy-efficient colors (up to 0.55 solar reflectance), and the total cost of ownership strongly favors metal. In a climate with 82 annual freeze-thaw cycles like Lincolnshire, asphalt deteriorates faster, making the comparison even clearer.

Yes. energy-efficient Interlock colors have thermal emissivity of 0.84 and initial solar reflectance up to 0.55 (Aged Copper Penny), meaning they reflect heat that dark asphalt absorbs and re-radiates into your attic. On Lincolnshire's ~3051 sunshine hours per year, this reflectance translates to measurably lower attic temperatures and reduced air-conditioning demand in summer. The Cool Roof Rating Council verification backs the performance data. Combined with the 30-year coating warranty that keeps the reflective finish intact, you're guaranteed long-term energy savings, not just at installation.

Interlock Metal Roofing has served the Lincolnshire and Lake County region since 2001, bringing over two decades of local expertise to every installation. The process is typically faster than asphalt work because panels install in large sections, and in most cases you can install directly over your existing roof (no costly tear-off). A straightforward residential installation usually takes 2–5 days depending on roof size and complexity. The local team understands Lake County weather patterns, building codes (including ICC-ES ESR-1790 compliance), and the specific challenges of our climate—from heavy snow load to frequent freeze-thaw stress.

Yes. Lincolnshire 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.
