Metal Roofing in Crapaud, Prince Edward Island — Lifetime Interlock® Aluminum Shingles Installed Locally

Metal roofs shed snow faster than asphalt because aluminum conducts heat and the smooth surface prevents ice dams that trap moisture. With about 182 cm of snow annually and roughly 73 freeze-thaw cycles per year, that matters: you avoid the wet-freeze-refreeze trap that damages shingles. Interlock panels are warranted to 120 mph wind resistance when properly installed, and the four-way interlocking design keeps panels seated even during heavy snow load shifts. Snow guards can be added if you want controlled shedding rather than full slides.

Aluminum expands and contracts minimally compared to asphalt or wood, so it tolerates Crapaud's 73 annual freeze-thaw days without cracking, curling, or splitting. The material is homogeneous—no tar to harden in winter or soften in summer. The roofing-grade 3105-H24 aluminum alloy meets ASTM B209 specs and won't absorb water, so ice can't form inside the material and cause internal stress. Combined with the Alunar 70% PVDF finish (warranted 30 years against chalking), the panels stay flexible through decades of our climate's temperature swings.

No. Aluminum contains no iron, so it cannot rust—ever. The 3105-H24 alloy develops a thin oxide layer that self-heals when scratched, actively protecting the metal underneath. Interlock applies the Alunar fluorocarbon finish to both sides of each panel specifically for salt-air environments like yours; this 30-year fade-and-chalk warranty has been field-tested from coastal homes to Antarctic research stations. That dual-coat approach is why Interlock has shipped roofs to salt-exposed homes since 1998 without corrosion claims. Steel roofing rusts through salt; aluminum simply doesn't.

Yes. Crapaud experiences typical gusts around 147 km/h, and Interlock panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to spec. The four-way interlocking design locks each panel to its neighbors on all four edges, distributing wind pressure across the entire roof plane rather than putting stress on individual fasteners. The ICC-ES evaluation ESR-1790 confirms code compliance under the IBC/IRC, which includes wind load tables specific to coastal and exposed regions. Proper installation by Maritime Metal Roofing Ltd. ensures every panel is seated correctly.

Almost never. The Interlock Slate installs at just 0.41 lb/sq ft, and even the heaviest profile—Mediterranean Tile—is about 96% lighter than concrete or clay tile and weighs only 0.59 lb/sq ft. Asphalt shingles weigh roughly 2.5–3.5 lb/sq ft by comparison. This feather-light weight means most homes can install Interlock directly over an existing asphalt roof without any structural work, saving thousands in labor and engineering. Your builder's existing framing has been carrying asphalt all along—aluminum is a relief to your structure, not a burden.

Interlock carries the UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty even covers perforation from hailstones up to 1.5 inches. Class 4 means the roof has been tested to withstand impact from 2-inch steel balls dropped from 20 feet. Some insurers recognize this rating and offer discounts because metal roofs file fewer hail claims than asphalt or wood shakes. Contact your insurer with the UL 2218 Class 4 specification; many carriers will reduce your premium, offsetting part of the roof's cost over time. It's worth asking before you install.

A metal roof costs more upfront—typically 2–3× asphalt—but it's the last roof you'll buy. Asphalt lasts 15–25 years; Interlock carries a lifetime limited material warranty for the original owner and a 50-year transferable term for the next owner, meaning zero replacement costs over your ownership and a major selling point if you move. The Guardian Warranty covers rusting, rotting, splitting, cracking, curling, and impact loss—all the failures that force asphalt replacement. Over 40–50 years, one aluminum roof beats two or three asphalt replacements, plus the landfill cost, tear-off labor, and roof-off-the-market downtime. The current promotion offers interest-free payments for 3 months and at least $2499 savings, lowering that upfront gap.

Remarkably little compared to asphalt, wood, or tile. No granule loss to monitor, no moss or algae growth, no wood rot or cracking. With Crapaud's 937 mm of annual rainfall, water runs off quickly; the four-way interlocking seams shed water upslope and won't pool or leak. You might clear leaves from gutters twice a year and inspect fasteners every 5–10 years—that's it. Asphalt requires periodic nailing, wood shakes need treatment and replacement of split pieces, and tile cracks with freeze-thaw. Interlock's ICC-ES ESR-1790 listing even qualifies the roof as CALGreen-verified for reduced maintenance, reducing long-term ownership headaches and cost.

Most residential installations—removal of old roof, new deck, underlayment, and metal panels—take 5–7 working days depending on roof size and weather. Because Interlock panels are so light (0.41–0.59 lb/sq ft), crews can often install directly over your existing asphalt roof if it's in good condition, cutting demolition and disposal time significantly. Maritime Metal Roofing Ltd. has served West PEI since 2007, so they know local weather windows and can schedule around Crapaud's typical 27 km/h winds and 182 cm of annual snow. They'll provide a firm timeline during your estimate and coordinate with other trades if needed.

Yes. Aluminum is non-combustible, and Interlock offers Class A fire classification—the highest rating available—on most profiles. Class A means the roof resists fire spread, flying embers, and flame penetration far better than wood shakes or asphalt. For homeowners in wildfire-prone zones or those simply concerned about fire safety, the non-combustible aluminum rating is a real asset. The ICC-ES ESR-1790 evaluation (reissued 2025) confirms code compliance with IBC/IRC fire standards, and many insurers offer discounts for Class A roofing. If fire safety is a priority for your family, ask Maritime Metal Roofing about the Class A option when you get your estimate.

Yes. Crapaud averages about 182 cm of snow, 937 mm of rain, roughly 73 freeze–thaw days a year, with peak wind gusts near 147 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.
