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

Aluminum's smooth, hard surface sheds snow and ice naturally — preventing the ice dams that trap moisture under asphalt shingles. With about 178 cm of snow annually and roughly 77 freeze-thaw days per year, your roof experiences constant expansion and contraction. Aluminum won't crack, curl, or split like asphalt or wood when temperature swings occur. The four-way interlocking panels stay watertight through the harshest seasonal shifts. Maritime Metal Roofing installs snow guards where needed, giving you control over safe shedding.

Aluminum contains no iron — it physically cannot rust. Instead, it forms a transparent oxide layer that self-heals when scratched, offering permanent corrosion resistance. The Alunar 70% PVDF fluorocarbon coating is applied to both sides of every panel, giving extra protection in salt-air environments. That dual-side finish is warranted 30 years against chalking and fading. Interlock has installed roofs from coastal homes to an Antarctic research station since 1998, proving aluminum thrives where steel would deteriorate within years.

Metal roofing is the last roof most homeowners install. While the initial cost is higher, asphalt requires replacement every 15–20 years, meaning two or three tear-offs and landfill fees over the roof's lifetime. Interlock's Guardian Warranty is lifetime limited and non-prorated — you're protected against rusting, rotting, splitting, and cracking for as long as you own the home. The current regional promotion offers interest-free payments for 3 months and saves at least $2499 on installation. When you factor in zero tear-offs, no re-roofing costs, and resale value, aluminum metal roofing typically costs less over 40 years.

Absolutely. Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. Alexandra experiences typical daily winds around 25 km/h with gusts reaching 150 km/h — well within the roof's design envelope. The interlocking system locks each panel to its neighbors on all four sides, distributing wind load evenly across the entire roof. This engineering prevents uplift and panel separation during severe coastal storms. Maritime Metal Roofing ensures proper installation so your roof performs when it matters most.

Interlock achieves UL 2218 Class 4 impact rating — the highest classification available — and the warranty covers perforation from hailstones up to 1.5 inches. This certification often qualifies homeowners for insurance discounts on comprehensive coverage. Unlike asphalt, which dents and cracks under hail impact, aluminum's hardness and flexibility absorb impact without permanent damage or loss of weatherproofing. Class A fire rating is also available for non-combustible protection. Check with your insurer about the discount potential — the combination of impact resistance and non-combustibility can meaningfully reduce your annual premium.

Far less than asphalt, wood, or tile. Aluminum won't rot, split, curl, or require resealing. With about 914 mm of annual rainfall and 2706 sunshine hours, your roof self-cleans naturally — rain washes debris away, and UV exposure won't degrade the aluminum or its Alunar coating. Asphalt requires regular inspections and shingle replacement; wood shakes need cleaning and oil treatment; tile cracks and requires mortar repointing. Your metal roof simply performs, year after year. Occasional gutter cleaning and snow-guard checks are all that's needed. It's CALGreen-verified for reduced maintenance, letting you spend time on what matters.

No. Interlock's aluminum panels are extraordinarily light — the Mediterranean Tile profile weighs about 0.59 lb/sq ft, roughly 96% lighter than concrete or clay tile. Even the heavier Shake profile comes in at just 0.58 lb/sq ft. Because of this minimal weight, your home's existing framing, trusses, and foundation require no reinforcement. You can often install the metal roof directly over your current asphalt shingles, saving the cost and mess of a tear-off. This lightweight advantage is especially valuable on older homes or those with modest structural capacity. Maritime Metal Roofing will assess your roof during the consultation to confirm the best installation approach.

No — aluminum is exceptionally resistant to freeze-thaw damage. With roughly 77 freeze-thaw days per year in Alexandra, your roof endures constant temperature swings. Asphalt becomes brittle in cold, cracks in freeze cycles, and loses flexibility. Wood shakes split and warp. Aluminum expands and contracts uniformly without cracking, curling, or losing structural integrity. The aluminum alloy (3105-H24 or 3003-H24, ASTM B209) is engineered for these exact stresses. Combined with the Guardian Warranty's coverage against splitting and cracking, you're protected against the very seasonal forces that shorten the life of traditional roofing.

The four-way interlocking panel design creates a watertight envelope. Water flows down the smooth aluminum surface to gutters without pooling or finding entry points. Alexandra's annual rainfall averages about 914 mm — substantial by most standards — yet the same interlocking system that resists 150 km/h gusts also prevents water infiltration. Unlike asphalt, where granules erode and expose the mat to moisture, or tile, where grouted seams fail, aluminum sheds water continuously without degradation. Proper installation by Maritime Metal Roofing includes gutter sizing and flashing details that manage peak rainfall events. The result is a roof that stays dry decade after decade.

The Guardian is a lifetime limited, non-prorated material warranty for the original owner — meaning you're covered for the entire lifespan with no declining benefits. It protects against rusting, rotting, splitting, cracking, curling, and loss of impact resistance. The coating itself is warranted 30 years against chalking and fading (measured by ASTM standards). When you sell, the warranty transfers once to the next owner, providing 50 years of coverage from completion. This transferability adds genuine resale value — future buyers inherit decades of protection. Combined with aluminum's inherent inability to rust and the rigorous ICC-ES evaluation (ESR-1790, reissued 2025), you're investing in a roof designed to outlast most home mortgages.

Yes. Alexandra averages about 178 cm of snow, 914 mm of rain, roughly 77 freeze–thaw days a year, with peak wind gusts near 150 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.
