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

Metal roofing sheds snow and ice effectively because aluminum's smooth surface and four-way interlocking panels prevent water from pooling underneath. With about 171 cm of annual snow and roughly 89 freeze-thaw cycles per year in this region, that matters—traditional asphalt can trap ice dams in freeze-thaw swings, but aluminum's light weight and panel design let snow slide cleanly without stressing your structure. Snow guards are available if you need them for safety.

No. Aluminum expands and contracts with temperature swings, but it doesn't absorb water, so freeze-thaw cycling can't crack or split it the way it damages asphalt, wood shakes, or concrete tile. Given New Maryland's 89 freeze-thaw days annually and nearly 1000 mm of rainfall, materials that trap moisture fail fast—aluminum's oxide layer sheds water and resists degradation from repeated freezing. This is why Interlock's warranty covers cracking and curling.

Aluminum cannot rust because it contains no iron. Instead, it develops a thin, self-healing oxide layer that actually protects it from corrosion. In New Maryland's wet climate—nearly 1000 mm of rain yearly—this matters enormously. To add another layer, Interlock applies Alunar 70% PVDF fluorocarbon coating to both sides of every panel, warranted 30 years against fading and chalking. Steel roofs rust; aluminum doesn't.

Yes. The four-way interlocking panels lock together so tightly that Interlock warrants its roofs to resist sustained winds up to 120 mph, with gusts beyond that. New Maryland experiences typical gusts around 121 km/h (about 75 mph), well within that range. The ICC-ES ESR-1790 evaluation confirms code compliance for wind loads across Canada. Unlike asphalt shingles, which can peel or lift, interlocked metal panels stay put.

No structural reinforcement is needed. Interlock's Slate installs at just 0.41 lb/sq ft and the Mediterranean Tile profile at 0.59 lb/sq ft—making the tile about 96% lighter than concrete or clay tile. Most existing roofs can support metal without any structural work, and the lightweight aluminum actually reduces long-term strain on your home. That's a real savings on labor and engineering.

Interlock metal roofing carries UL 2218 Class 4 impact rating—the highest available—and the warranty even covers perforation from hailstones up to 1.5 inches. That top rating may qualify you for insurance discounts depending on your provider. In a region with variable spring weather and unpredictable storm systems, Class 4 rating gives you real peace of mind and documented proof your roof can handle severe impact.

Far less than asphalt, wood, or tile. Aluminum won't rot, split, curl, or deteriorate from UV exposure the way asphalt does under New Maryland's 2862 annual sunshine hours. You don't need to replace shingles, repair wood rot, or power-wash mineral buildup. Basic gutter cleaning and the occasional inspection—that's it. The CALGreen-verified design reflects the reduced-maintenance standard, lowering your cost of ownership over decades.

Yes. Aluminum is approximately 95% recyclable at end of life, versus asphalt shingles that end up in landfills by the truckload. Over a 50-year span—the transfer warranty period—you'll install one metal roof instead of three or four asphalt roofs, eliminating the tear-off waste cycle entirely. In a region receiving nearly 1000 mm of rain annually, choosing a 50-year roof over a 20-year one reduces long-term environmental impact significantly.

Metal roofing costs more upfront but is the last roof you'll buy. A typical asphalt roof lasts 15–20 years; Interlock's lifetime limited warranty for the original owner covers rusting, rotting, splitting, cracking, curling, and impact resistance—and transfers 50 years to the next owner. Over 50 years, one metal roof costs less than three asphalt roofs plus labor, repairs, and waste removal. The current regional promotion offers interest-free payments for 3 months and saves at least $2499 on installation.
