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

Yes—aluminum actually performs better than asphalt in freeze-thaw environments. Long Grove experiences about 82 freeze-thaw days per year, which causes asphalt to crack and curl as it expands and contracts. Aluminum's oxide layer self-heals when scratched, and it doesn't absorb water the way shingles do, so ice formation and thawing won't degrade it. The 3105-H24 aluminum alloy used in Interlock panels is specifically chosen for climates with constant temperature swings. You're looking at a roof that gets tougher as the seasons change, not weaker.

Long Grove averages about 73 cm of snow per year, and metal roofing handles it exceptionally well because of its weight and surface. Interlock's Shingle profile weighs only 0.41 pounds per square foot—so light that snow clings to the standing seam design rather than sliding off dangerously. The smooth aluminum surface prevents ice dam formation better than asphalt, and you can add snow guards where needed without reinforcing your structure. The warranty covers wind up to 120 mph, so the panels won't lift under pressure from heavy snow or wind-driven drifts common in this region.

Completely sealed. Long Grove receives approximately 993 mm of rainfall per year, and Interlock's four-way interlocking design means water has nowhere to go but down and off. Each panel locks to its neighbors on all four sides, eliminating the overlap gaps where asphalt shingles fail. The ICC-ES evaluation report ESR-1790 confirms compliance with IBC/IRC water-shedding requirements. When installed over solid decking with underlayment—standard practice—the system is as leak-proof as metal roofing gets. The Guardian warranty explicitly covers perforation and water intrusion, so you have protection that asphalt simply cannot match.

Yes, without question. Long Grove's typical daily-max winds reach 19 km/h, with gusts up to 97 km/h, and Interlock panels are warranted to 120 mph (193 km/h) when installed to specification. The four-way interlocking system means each panel is mechanically locked to its neighbors—no room for wind to get underneath and lift. The UL 2218 Class 4 impact rating covers both hail and wind-driven debris. Storms with sustained gusts in the range Long Grove actually sees won't budge these panels. Homeowners in coastal salt-air regions and Antarctic research stations rely on the same design, so a Midwest wind load is well within tolerance.

Aluminum cannot rust because it contains no iron—that's the material difference that matters. Steel roofs oxidize and deteriorate; aluminum develops a thin oxide layer that self-heals when scratched. Long Grove's 993 mm annual rainfall and 73 cm snow mean constant moisture exposure, exactly where aluminum's non-reactive nature shines. The Alunar 70% PVDF fluorocarbon finish is applied to both sides of every panel—not just the top—for extra protection against salt air and freeze-thaw corrosion. After 26 years in coastal British Columbia and decades in harsher climates, Interlock panels show no rust or structural corrosion. That's not marketing; that's aluminum chemistry.

No structural reinforcement needed. Interlock's Mediterranean Tile profile, which replicates the heaviest traditional tile look, weighs only 0.59 pounds per square foot—about 96% lighter than actual concrete or clay tile. Most homes can handle that weight without modification. The Slate and Cedar Shingle profiles are even lighter. This matters in Long Grove because your existing framing doesn't have to bear the load penalty that slate or tile would impose, yet you get the same visual result. Installation can happen directly over most existing roofs, saving thousands on tear-off and structural work. The lightweight aluminum just sits there and protects you for decades.

Virtually none compared to asphalt or wood shake. Long Grove's 993 mm rain and 73 cm snow annually wash the roof naturally; no moss or debris accumulation like you'd see on asphalt. The Alunar finish is warranted 30 years against chalking and fading, so you won't see the graying that asphalt develops. Unlike wood shakes—which split and curl in freeze-thaw cycles—aluminum doesn't absorb moisture and is CALGreen-verified for reduced maintenance. No periodic sealant reapplication. No algae growth. No buckled or missing pieces after wind. Inspect gutters and fasteners annually as part of home upkeep, but the roof itself requires almost no attention. That's the efficiency gain over its 50+ year lifespan.

Yes, when you calculate the total cost of ownership over the roof's life. An asphalt roof lasts 15–20 years in Long Grove's climate—multiply that by 3–4 replacements, plus disposal costs each time. Interlock's lifetime limited warranty for the original owner (50 years transferable to the next owner) means one installation covers most homeowners permanently. The Alunar 30-year coating warranty, combined with zero corrosion risk and minimal maintenance, eliminates the hidden costs that asphalt accumulates. You're not buying a roof that degrades; you're buying the last roof you install. Over 50 years, the math favors aluminum decisively—fewer tear-offs, no landfill fees, one warranty instead of multiple replacements.

Yes, through reflective coatings and thermal design. Interlock's energy-efficient colors achieve up to 0.55 initial solar reflectance (Aged Copper Penny profile) and 0.84 thermal emissivity, meaning the roof reflects heat that asphalt absorbs and radiates. Long Grove receives about 3051 sunshine hours per year, and even during warm months, a reflective metal roof keeps your attic cooler than dark asphalt would. The Cool Roof Rating Council rates these finishes for measurable energy savings. You won't eliminate air conditioning, but you'll reduce its runtime and cost. The same reflective finish that cools your home in summer is also durable under Long Grove's intense UV exposure—the Alunar fluorocarbon coating is engineered for long-term performance in variable sunlight.

Interlock Metal Roofing has been serving the region since 2001—over two decades of installation experience in Lake County's specific climate and soil conditions. They understand Long Grove's rainfall patterns, freeze-thaw intensity, and the particular wind loads this area faces. Local installation means faster scheduling, site familiarity, and warranty support from someone who knows the material intimately and can be back quickly if anything needs attention. The same installer who puts your roof on is the same one who stands behind it. That continuity—knowing your address, your weather history, and your specific roof profile—is worth more than a distant contractor. You're dealing with professionals who've installed thousands of Interlock panels in conditions identical to yours.

Yes. Long Grove 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.
