Metal Roofing in Sharon, Connecticut — Lifetime Interlock® Aluminum Shingles Installed Locally

Yes. Aluminum's crystalline structure doesn't absorb water, so it won't crack, split, or warp during freeze-thaw cycling—Sharon experiences about 92 freeze-thaw days annually. The material expands and contracts smoothly without stress accumulation. Unlike asphalt shingles, which become brittle after repeated freeze-thaw, or wood shakes, which split along the grain, Interlock's roofing-grade 3105-H24 aluminum alloy (ASTM B209) maintains its integrity through decades of Connecticut winters. The four-way interlocking seams also accommodate seasonal movement without leaking.

Interlock handles Connecticut snow easily because aluminum is extraordinarily light—the Slate profile installs at just 0.41 lb per square foot, versus 700+ pounds per square for slate tile. With about 95 centimeters of snow falling annually in Sharon, the weight of snow buildup becomes a structural concern for asphalt or tile; aluminum lets you keep the snow on the roof (for insulation) without reinforcing beams. Snow also sheds faster on smooth metal than on shingles, and optional snow guards let you control that shedding. The four-way interlocking seams stay watertight as snow and ice melt.

No. Sharon averages 1,060 millimeters of rain annually, and Interlock's four-way interlocking aluminum panels are engineered to shed water, not trap it. Each panel locks on all four sides, creating continuous pathways that funnel water down and off the roof. Installed over a solid deck and ice-and-water underlayment (standard practice), they perform identically to asphalt in rainfall—the difference is that asphalt erodes over 20 years while aluminum doesn't. The Guardian warranty covers leakage from the product itself, giving you assurance that water management is built into the system.

Aluminum cannot rust because it contains no iron—the element that oxidizes in steel. Instead, aluminum develops a thin, self-healing oxide layer that protects the base metal. Even if the coating scratches, the oxide regenerates, stopping corrosion at that spot. Connecticut's 1,060 mm of annual rainfall and typical wind gusts to 117 km/h don't corrode aluminum. Interlock's Alunar 70% PVDF fluorocarbon finish is applied to both sides of each panel and is warranted 30 years against chalking and fading. Steel roofing, by contrast, requires constant vigilance against rust spots and coating damage.

Yes. The roof is warranted to resist wind speeds up to 120 mph when installed to spec—Connecticut's gusts typically reach 117 km/h, well within that range. Four-way interlocking (top, bottom, left, right) means each panel locks into its neighbors, distributing wind load across the entire roof rather than relying on fasteners alone. This redundancy is why the system earns its wind warranty. Even extreme gusts don't lift or separate panels. Asphalt shingles, fastened individually, begin peeling at 60–70 mph; metal's integration is fundamentally stronger.

Interlock aluminum 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. In Sharon's climate, large hail is infrequent, but the protection is there. Some insurers offer discounts for metal roofing with Class 4 ratings because claims are rare and repair costs are lower than asphalt or tile replacement. Unlike slate or clay tile, which fracture under hail, aluminum deforms slightly and remains waterproof. Contact your agent—many carriers recognize this durability with lower premiums or higher claim limits.

No. The Interlock Mediterranean Tile profile, the heaviest offered, weighs just 0.59 lb/sq ft—about 96% lighter than concrete or clay tile. Your framing carries asphalt shingles at roughly 2.5 to 4 lb/sq ft; aluminum replaces that load with a fraction of the weight. Structural reinforcement is not required, and you can install Interlock directly over most existing roofs, eliminating tear-off costs and debris. This light weight also reduces strain on fasteners and flashing, lowering long-term maintenance. For Sharon homeowners, it means upgrading from asphalt without calling a structural engineer.

Virtually never. Aluminum doesn't require the annual inspections, repairs, or cleaning that asphalt, wood shake, or tile demand. Asphalt loses granules in heavy rain (1,060 mm annually in Sharon), requiring frequent touch-ups and eventual replacement. Wood shakes split and curl. Tile cracks in freeze-thaw cycles. Interlock aluminum resists all three. Gutters collect leaves, not roof debris. The Alunar coating is warranted 30 years against chalking and fading, so color stays true. Many owners report they've never done anything to their aluminum roofs after installation—just checked gutters and moved on. That translates directly to lower lifetime cost.

The Guardian is a lifetime limited, non-prorated material warranty for the original owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance—essentially everything that fails in other roof types. It's transferable once, giving the next owner 50 years of coverage from completion. In Sharon's freeze-thaw (92 days annually) and moisture environment, this means your roof is protected against the exact failures that plague asphalt and wood. No prorating means claims at year 20 are treated the same as year 5. Asphalt shingles, by comparison, carry 15–25 year limited warranties that decline year by year—you're paying more for less protection.

Yes. Interlock's energy-efficient colors have initial solar reflectance up to 0.55 (Aged Copper Penny) and thermal emissivity of 0.84, meaning they reflect summer heat rather than absorb it the way asphalt does. Sharon receives about 3,034 sunshine hours annually, so even moderate heat reflection adds up across the cooling season. Cool Roof Rating Council ratings confirm the benefit. In winter, you still gain—that same reflectance means less heat loss through the roof in frigid months. The net result is lower HVAC cycling year-round. Asphalt shingles absorb heat, raising attic temperatures and forcing air conditioning to work harder during the 95 centimeters of snow melt and the warm months that follow.

Yes. Sharon averages about 95 cm of snow, 1060 mm of rain, roughly 92 freeze–thaw days a year, with peak wind gusts near 117 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.
