Metal Roofing in Summit, Rhode Island — Lifetime Interlock® Aluminum Shingles Installed Locally

Interlock panels shed snow far better than asphalt because aluminum is slick and doesn't absorb heat the way dark shingles do. Summit gets about 75 cm of snow most years, and the smooth surface prevents the compacted ice layer that leads to ice dams. The four-way interlocking system keeps water sealed out even when melt cycles hit the 80 freeze-thaw days you experience annually. Snow guards are available if you need to control where snow slides off.

No. Aluminum expands and contracts with temperature swings, but it doesn't absorb water like wood or asphalt, so ice can't form inside the material and cause cracking. With about 80 freeze-thaw cycles per year in Summit, this is genuinely important—asphalt shingles fail precisely because water gets trapped under the surface. Aluminum's oxide layer actually self-heals when scratched, so micro-damage from thermal stress doesn't accumulate into rust or deterioration.

Aluminum cannot rust because it contains no iron—the element that oxidizes and flakes away. Instead, a thin oxide layer forms and self-heals automatically when scratched. Interlock uses roofing-grade 3105-H24 and 3003-H24 aluminum alloy per ASTM B209, coated both sides with Alunar 70% PVDF fluorocarbon finish (30-year warranty against chalking). In a humid state with 1264 mm of annual rain, this matters: you avoid the structural decay that rusting steel causes and get a roof that outlasts asphalt by decades without corrosion.

Yes. Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. Summit's typical wind gusts reach about 125 km/h, so you're covered with room to spare. The interlock system means each panel locks to its neighbors on all four sides—wind can't lift or peel a single panel away. The warranty gives you confidence in storms that would tear asphalt shingles clean off.

Interlock aluminum roofing carries the highest impact rating available: UL 2218 Class 4, which tests the most severe hail scenarios. The warranty even covers perforation from hailstones up to 1.5 inches. Unlike asphalt shingles that crack or break under hail impact, aluminum dents but stays intact—no leaks, no water intrusion. Some insurers offer discounts on metal roofs with this rating. Call your agent to ask; if you're in a hail-prone area, the durability alone can lower your premiums over time.

energy-efficient Interlock colors reflect far more heat than asphalt absorbs. Thermal emissivity reaches 0.84 with solar reflectance up to 0.55 (Aged Copper Penny), meaning sun energy bounces away rather than heating your attic. Summit gets about 3075 sunshine hours per year, so reflective coatings add up to real savings. Cool Roof Rating Council certification backs the performance. On top of that, metal doesn't expand and contract like asphalt, so you avoid the thermal stress that shortens shingle life in climates with 80 freeze-thaw days annually.

Yes—Interlock's extraordinary light weight means no reinforcement needed. The Mediterranean Tile profile, which mimics heavy clay or concrete, weighs just 0.59 lb/sq ft and installs at about 96% lighter than real tile. Cedar Shingle runs 0.41 lb/sq ft. This matters because you can install over your existing roof in most cases, saving tear-off labor and landfill costs. With roofing-grade aluminum and proper fastening per ICC-ES ESR-1790, your home's framing handles it easily—no structural engineering required.

Interlock backs every roof with The Guardian: a lifetime limited, non-prorated material warranty for the original owner covering rusting, rotting, cracking, curling, and impact loss. It transfers once to the next owner for 50 years from completion. The Alunar coating is separately warranted 30 years against fading and chalking per ASTM D4214 and D2244. This is genuinely the last roof you'll buy—aluminum doesn't degrade like asphalt (which loses granules in heavy 1264 mm annual rainfall) or wood (which rots through freeze-thaw cycles). Your money compounds across decades.

Interlock Metal Roofing (New England) Inc. has served the region since 1999 and knows New England weather inside out. They understand your snow loads, salt air if you're near the coast, and freeze-thaw demands. They're familiar with ICC-ES ESR-1790 compliance and local building departments. Right now, the region is running a promotion: no payments and no interest until Spring 2027, or 10% off installation. Contact them for a site visit and estimate—they'll walk you through profile choices, color options, and financing.

Aluminum is about 95% recyclable and can be melted down and reused infinitely without losing properties. Asphalt shingles, by contrast, are torn off and dumped in landfills by the millions of tons each year—a cycle that repeats every 15–20 years. Interlock's 50-year transferability and lifetime warranty mean your roof stays out of the waste stream for generations. Manufacturing roofing-grade aluminum does consume energy upfront, but the avoided tear-offs over just two lifecycles (yours plus the next owner's 50-year term) erases that carbon cost and keeps thousands of pounds of waste out of landfills.

Yes. Summit averages about 75 cm of snow, 1264 mm of rain, roughly 80 freeze–thaw days a year, with peak wind gusts near 125 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.
