Metal Roofing in Moncton, New Brunswick — Lifetime Interlock® Aluminum Shingles Installed Locally

Yes—aluminum's smooth, hard surface sheds snow and ice far more effectively than asphalt. Moncton receives about 195 cm of snow annually, and the region's 89 freeze-thaw days create ideal conditions for ice damming on conventional roofs. Interlock's four-way interlocking panels lock moisture out while the slick profile prevents ice adhesion. Snow guards can be added if you want to retain snow for insulation. The lightweight design—about 96% lighter than slate or tile—means no structural reinforcement is needed, even over existing roofs, so installation costs stay predictable.

Aluminum thrives through freeze-thaw cycles because it has no iron and cannot rust. The material's oxide layer self-heals when scratched, so winter moisture poses no corrosion risk. With approximately 89 freeze-thaw days per year in your region, this durability is a genuine advantage over asphalt, which becomes brittle and cracks under repeated freezing stress. Interlock's 3105-H24 aluminum alloy (ASTM B209) is roofing-grade specifically for this punishment. The Alunar 70% PVDF fluorocarbon coating, warranted 30 years against chalking and fading, protects the substrate through your harshest seasons.

No—aluminum cannot rust because it contains no iron. Instead, it forms a self-healing oxide layer that actually protects the metal underneath. Moncton averages 943 mm of rain per year, making corrosion resistance critical. This is why Interlock applies its Alunar 70% PVDF fluorocarbon finish to both sides of every panel—extra insurance in damp, salt-air environments. Steel roofing requires constant maintenance to prevent rust; aluminum's chemistry eliminates that concern entirely. The Guardian lifetime limited warranty covers rusting, confirming that corrosion simply is not a failure mode for this material.

Yes. Interlock panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. Moncton experiences typical daily-max winds around 19 km/h with gusts reaching 116 km/h—well below that threshold. The four-way interlocking design locks each panel to its neighbors, distributing wind load across the entire roof system rather than relying on fasteners alone. This engineering is validated by ICC-ES ESR-1790 evaluation (reissued 2025, covering IBC/IRC code). The Intertek listing and UL testing confirm that properly installed Interlock roofing outperforms conventional shingles in high-wind conditions.

Interlock achieves UL 2218 Class 4 impact rating—the highest available—and the warranty even covers perforation from hailstones up to 1.5 inches. Most hail events in Atlantic Canada fall short of that severity. Many insurers recognize metal roofing's durability and offer premium discounts; ask your agent about your specific policy. Unlike asphalt shingles, which degrade after hail impact even without visible damage, aluminum's hard surface deflects impact and retains its integrity. The combination of proven impact performance and no rust risk means your roof maintains its value and protection year after year, regardless of weather events.

The Guardian warranty is lifetime limited and non-prorated for the original owner—meaning no deductibles rise and no coverage phases out. It covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance. For the second owner, coverage transfers once and extends 50 years from completion. This structure reflects the reality that aluminum roofing outlasts asphalt by decades. With Moncton's 195 cm annual snowfall and 89 freeze-thaw days, you need a roof designed for that climate; Interlock has been manufactured since 1998 and installed from coastal salt-air homes to Antarctic research stations. Plan for this to be your last roof.

Yes—over a 40-50 year horizon, metal roofing costs less than replacing asphalt three times. Asphalt typically lasts 15-20 years in Moncton's climate, especially with 943 mm of rain and 89 freeze-thaw cycles annually; metal lasts 50+ years with a lifetime warranty. You eliminate tear-off labor, disposal, and the disruption of multiple replacements. The Guardian lifetime coverage is non-prorated, so repair costs vanish. Current promotion: enjoy interest-free payments for 3 months and save at least $2499 on installation. Maritime Metal Roofing Ltd. has served the region since 2007 and can walk you through the genuine cost comparison for your home.

Interlock's extraordinary lightness—the Shingle installs at 0.41 lb/sq ft, Shake at 0.58—means it can install directly over most existing asphalt roofs without structural reinforcement. This eliminates one of the biggest cost and time drains: the tear-off. Installation typically completes in days rather than weeks, depending on roof size and complexity. No structural upgrades are required because the weight is negligible compared to slate or tile. Maritime Metal Roofing Ltd. will assess your current roof and provide a timeline specific to your home. The four-way interlocking design speeds installation and ensures a weathertight, wind-resistant seal.

Virtually none. Unlike asphalt shingles, which degrade under Moncton's 2797 annual sunshine hours and need periodic repairs, aluminum panels resist fading and chalking—the Alunar coating is warranted 30 years (ASTM D4214/D2244). Unlike wood shake, no splitting or rot occurs. Unlike ceramic tile, no cracking from freeze-thaw (you experience about 89 cycles per year). Occasional gutter cleaning and inspection of fasteners is all that's required. The CALGreen verification confirms that Interlock meets reduced-maintenance standards. This simplicity is baked into the Guardian warranty structure: no annual maintenance requirements, no prorating—just protection.

The four-way interlocking design and ICC-ES ESR-1790 code compliance ensure that water flows off and away. Moncton receives about 943 mm of annual rainfall—substantial, but metal roofing is engineered for high-volume wet climates. Proper installation over solid decking and underlayment creates a dual-plane defense; the underlayment captures any water that penetrates the panel interlock (rare) and directs it safely to gutters. The Guardian warranty covers water intrusion as a defect. Unlike asphalt, which absorbs water over time, aluminum sheds it instantly. When installed to spec by Maritime Metal Roofing Ltd., your roof handles Moncton's rain without pooling, ice damming, or rot.

Yes. Moncton averages about 195 cm of snow, 943 mm of rain, roughly 89 freeze–thaw days a year, with peak wind gusts near 116 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.
