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

Yes—Interlock's lightweight aluminum panels (Shake at 0.58 lb/sq ft) shed snow far more efficiently than asphalt or wood. Old Mystic gets about 75 cm of snow annually and around 87 freeze-thaw cycles per year, creating the exact conditions where metal's smooth surface and low mass prevent ice dam formation. Snow slides off before it becomes a structural burden, and the four-way interlocking design holds any remaining snow safely in place until melting.

Aluminum thrives in freeze-thaw conditions because it expands and contracts without cracking or absorbing water. With 87 freeze-thaw days per year in New London County, traditional materials like slate and wood fail—but aluminum's oxide layer self-heals when scratched, and the Alunar 70% PVDF coating (warranted 30 years) resists weathering across both sides of every panel. The material simply cannot rot or split, which are the primary failure modes in your climate.

No. Interlock panels are four-way interlocking with a 1/4-inch standing seam overlap that sheds water faster than it falls. Old Mystic averages 1,208 mm of rain per year, but the geometry of metal roofing—smooth surface, gravity, and interlocking seams—guarantees drainage. Pair that with solid decking and underlayment (installed per ICC-ES ESR-1790), and you get the same leak protection as asphalt, with zero risk of rotting plywood beneath.

Aluminum cannot rust because it contains no iron—the element that oxidizes to form rust. Instead, aluminum develops a microscopically thin protective oxide layer that self-heals when scratched or worn. Both sides of every Interlock panel receive Alunar 70% PVDF fluorocarbon coating, providing extra corrosion resistance in salt air or harsh climates. This dual-sided protection is why Interlock roofs operate reliably from coastal homes to Antarctic research stations.

Yes. Old Mystic experiences gusts up to 127 km/h, and Interlock's four-way interlocking panels are warranted to resist wind speeds up to 120 mph (193 km/h). Each panel locks to its neighbors on all four sides, creating a unified structure that distributes wind load evenly rather than exposing nail holes or seams. The interlocking design is why the warranty covers full wind performance when installed to specification.

Interlock achieves UL 2218 Class 4—the highest impact rating available—and the warranty covers perforation from hailstones up to 1.5 inches. Many insurers recognize this non-denting, Class 4 rating and offer discounts on premiums because aluminum roofs have an exceptional claims history. Contact your agent with the UL 2218 Class 4 certification and ICC-ES ESR-1790 documentation; they can assess your specific policy.

No. Interlock's Mediterranean Tile profile installs at 0.59 lb/sq ft—about 96% lighter than concrete or clay tile—and the Shake profile is only 0.58 lb/sq ft. This extraordinary lightness means you can install Interlock over most existing roofs without structural reinforcement. Because old Connecticut homes often have aging framing, metal roofing's low weight eliminates a major installation barrier and avoids the cost and disruption of structural upgrades.

Interlock's 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 warranty is one-time transferable, providing the next owner 50 years of coverage from completion. This longevity stems from aluminum's inability to rust or rot and the Alunar 70% PVDF coating's 30-year fade guarantee (ASTM D4214/D2244), making it genuinely the last roof you install.

Yes. energy-efficient Interlock colors achieve initial solar reflectance up to 0.55 (Aged Copper Penny) and thermal emissivity of 0.84, meaning they reflect heat that asphalt absorbs and re-radiates into your home. Old Mystic averages about 3,066 sunshine hours yearly, making reflective coatings valuable for summer comfort. Cool Roof Rating Council certification confirms this performance; you'll see measurable energy savings, especially if you're replacing a dark asphalt roof.
