Metal Roofing in Lewis, Vermont — Lifetime Interlock® Aluminum Shingles Installed Locally

Metal roofs shed snow and ice better than asphalt because the smooth, hard surface resists buildup and the lightweight panels—the Slate weighs just 0.41 lb/sq ft—flex slightly under load without cracking. Lewis averages 229 cm of snow annually and experiences about 82 freeze-thaw cycles per year; aluminum's non-corrosive oxide layer withstands repeated thawing without damage, and you can add snow guards to match your local code. No ice dams form the way they do under asphalt's insulating blanket.

Aluminum will not crack, warp, or degrade from freeze-thaw stress because it has no iron to rust and its oxide layer self-heals when scratched—a critical advantage in Essex County's roughly 82 freeze-thaw days per year. Unlike slate, cedar, or concrete tile, which can split when water freezes in their pores, roofing-grade 3105-H24 aluminum alloy (ASTM B209) simply expands and contracts uniformly. The Alunar® 70% PVDF coating protects against salt-air corrosion and UV damage across 2,737 annual sunshine hours.

Yes—the four-way interlocking panels hold firm under wind speeds up to 120 mph, and Lewis's typical gusts of about 110 km/h (68 mph) are well within the warranty rating. The interlocking design distributes wind load across the entire roof system, so individual panels won't lift or separate during the storms that occur in this region. The UL 2218 Class 4 hail rating also means the same robust construction protects against both wind and impact.

Hail does not puncture Interlock panels under normal conditions—they carry the UL 2218 Class 4 impact rating (the highest available) and the warranty even covers perforation from hailstones up to 1.5 inches. Many insurers recognize this durability and offer discounts on homeowner policies, though you'll want to check with your agent. Essex County's documented severe weather justifies the upgrade, and the 30-year Alunar® coating warranty ensures the finish stays intact through seasonal storms.

Aluminum contains no iron, so it cannot rust—period. Instead, it forms a thin, invisible oxide layer that protects the metal underneath, and this layer actually self-heals when scratched. In Lewis, where 904 mm of annual rain and freeze-thaw cycles would corrode steel, aluminum stays sound for a lifetime. The Alunar® 70% PVDF fluorovarbon finish (both sides of each panel) adds a 30-year warranty against chalking and fading, giving you two layers of protection where steel would need constant maintenance.

Your frame almost certainly is—the Cedar Shingle profile weighs just 0.41 lb/sq ft, and even the Mediterranean Tile profile is about 96% lighter than real concrete or clay tile. This means no costly structural reinforcement is required, and you can often install the new roof directly over your existing asphalt shingles, saving tear-off labor and landfill fees. The Interlock® system has been installed from coastal homes (subject to salt spray) to an Antarctic research station, so weight is never the limiting factor.

The Guardian lifetime limited warranty covers material defects (rusting, rotting, splitting, cracking, curling, and loss of impact resistance) for the original owner and is transferable—the next owner receives 50 years of coverage from completion. There is no pro-rated decline; you're covered the same way year one as year thirty. Combined with Interlock's record since 1998 and installations across extreme climates, the roof is designed to outlast the house, making it the last roof you'll buy.

Maintenance is minimal compared to asphalt, wood, or tile. Aluminum won't rot, split, curl, or require sealing every few years; you simply rinse it off occasionally to keep debris clear. The system has been verified by CALGreen for reduced maintenance, and with 904 mm of rain and about 2,737 sunshine hours annually, nature does much of the cleaning. Your only proactive steps are checking flashing after storms and ensuring gutters stay clear—far simpler than the repairs wood shakes or slate demand.

Over the roof's life, metal is the better value because you eliminate the asphalt tear-off-to-landfill cycle and install only once. The Guardian warranty and 50-year transferability boost resale appeal and lower your long-term cost per year of protection. Current promotion: no payments and no interest until Spring 2027, or 10% off installation. When you factor in that asphalt shingles fail in Essex County's 82 annual freeze-thaw cycles and require replacement, a single aluminum roof paid over time or in one sum beats three asphalt roofs over the same timeline.
