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

Yes—aluminum actually thrives in freeze-thaw conditions. Union Village experiences about 83 freeze-thaw days per year, which is brutal on asphalt and wood shingles because water infiltration leads to expansion and splitting. Aluminum doesn't absorb water, so it won't crack, curl, or rot. The 3105-H24 alloy and PVDF coating (warranted 30 years against degradation per ASTM D4214) remain stable through repeated temperature swings. That's why Interlock panels have been installed from coastal homes to Antarctica—the material gets stronger under those exact stresses.

Union Village gets roughly 76 cm of snow annually, and a metal roof sheds it faster than asphalt because the smooth, hard surface offers less friction. The four-way interlocking profile (ICC-ES ESR-1790 certified) keeps panels locked together, preventing movement during thaw cycles that can separate seams. Snow guards are available if you want to control slide-off timing near walkways. The lightweight design—around 0.41 lb/sq ft for the Slate profile—means zero risk of snow load overloading your structure, unlike slate or tile, which would require expensive reinforcement.

No. Union Village averages about 1200 mm of annual rainfall, and the four-way interlocking aluminum panels are engineered to shed water continuously without pooling. Each panel locks on all four sides, creating a unified surface where water flows straight down; there's nowhere for it to collect or find a seam to exploit. The Alunar® PVDF coating on both sides ensures water beads off without adhesion. Installed over a solid deck with underlayment (our standard practice), your roof performs like asphalt in rain but without asphalt's tendency to deteriorate when water inevitably breaches damaged shingles.

Completely safe—and this matters in Union Village, where typical wind gusts reach about 118 km/h. Interlock panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed per spec, and they achieve that through four-way mechanical interlocking that distributes lateral forces across the entire roof plane rather than relying on fasteners alone. A traditional shingle roof with gusts of that magnitude creates uplift, but the interlocked design resists it. UL 2218 Class 4 impact rating also proves durability under the mechanical stress wind produces.

Aluminum actually performs better than asphalt in hail. Interlock achieves UL 2218 Class 4—the highest impact rating available—and the Guardian Warranty even covers perforation from hailstones up to 1.5 inches. Most homeowners don't experience hail damage, but when you do get a storm, aluminum's non-combustible nature and impact resistance often qualify you for insurance premium reductions. Call your insurer with the UL 2218 Class 4 rating and non-combustible material spec; many carriers offer 5–15% discounts for metal roofs because they file fewer claims than asphalt.

Aluminum cannot rust because it contains no iron—iron is what oxidizes and corrodes. Instead, aluminum forms a thin, transparent oxide layer that actually protects the alloy beneath. When scratched, that oxide layer self-heals. The 3105-H24 and 3003-H24 aluminum alloys (ASTM B209) combined with the Alunar® 70% PVDF fluorocarbon coating (applied to both sides) create a two-layer defense against salt air, heavy rain (Union Village gets about 1200 mm yearly), and the chemical stew that accelerates steel corrosion. This is why Interlock panels perform identically whether installed in coastal salt spray or inland—the material itself is immune.

Your framing can almost certainly handle it without reinforcement. That's one of aluminum's biggest structural advantages. The Mediterranean Tile profile, despite looking like real clay or concrete tile, weighs only about 0.59 lb/sq ft—roughly 96% lighter than actual tile. Even the heavier Shake profile runs just 0.58 lb/sq ft. Asphalt shingles are around 2.5 lb/sq ft, so a metal roof is actually lighter than what your roof already supports. This means installation over your existing roof is possible in most cases, avoiding costly tear-off labor and landfill disposal.

Yes. Interlock's energy-efficient colors reflect solar heat instead of absorbing it, with thermal emissivity up to 0.84 and reflectance as high as 0.55 (Aged Copper Penny). Since Union Village receives about 3050 sunshine hours annually, that reflection adds up over time. Cool Roof Rating Council testing confirms our panels reflect heat that asphalt absorbs and stores, so your attic stays cooler in summer and your AC runs less. Winter savings come from retaining interior heat; the reflective properties work in both directions. Over a 50-year roof life, the compounding effect on heating and cooling costs is significant.

Virtually none compared to asphalt or wood. Asphalt shingles need inspection every few years, replacement of curled or cracked shingles, gutter cleaning after every heavy rain, and moss/algae treatment in humid climates—Union Village's 1200 mm rainfall and 83 freeze-thaw days create ideal conditions for all three problems. Wood shakes split and rot. Metal roofs require no coating reapplication, no shingle replacement, no preventive sealant. Rain washes the Alunar® PVDF finish (warranted 30 years against fading and chalking); that's your maintenance plan. Most owners hose off gutters once a year. The CALGreen verification confirms reduced-maintenance design.

The Guardian Warranty is a lifetime limited, non-prorated material warranty for you as the original owner—covering rust, rot, splitting, cracking, curling, and loss of impact resistance. It's also one-time transferable, giving the next owner 50 years of coverage from completion. In practical terms, these roofs regularly outlast 50+ years; Interlock has been manufacturing panels since 1998, and early installations from that era are still performing. The 30-year PVDF coating warranty (ASTM D4214 and D2244 standards) is separate and addresses finish degradation. That combination—non-prorated coverage for life plus half a century for the next owner—is unmatched in the industry.

Yes. Union Village averages about 76 cm of snow, 1198 mm of rain, roughly 83 freeze–thaw days a year, with peak wind gusts near 118 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.
