Metal Roofing in Fundy–Albert, New Brunswick — Lifetime Interlock® Aluminum Shingles Installed Locally

Aluminum's smooth, hard surface sheds snow and ice far more effectively than asphalt or wood. With about 185 cm of annual snowfall and 83 freeze-thaw days per year in this region, the metal panels naturally prevent ice dam buildup that cracks shingles or creates leaks. The four-way interlocking seams stay sealed even as panels expand and contract through repeated freezing and thawing. Snow guards are available if you prefer to retain snow for insulation. This durability under Fundy–Albert's heavy winter conditions is why the Shake and Slate profiles perform exceptionally well in salt-air coastal climates with extreme seasonal stress.

Aluminum contains no iron, so it cannot rust—period. Instead, it develops a self-healing oxide layer that protects the metal beneath. When scratched, this layer reforms automatically. In coastal salt-air environments like Fundy–Albert, this matters enormously: steel roofing corrodes aggressively near ocean salt, but aluminum thrives. Interlock panels are manufactured from roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209) and coated with Alunar 70% PVDF fluorocarbon finish on both sides—extra protection in salt air. The 30-year coating warranty covers chalking and fading. This combination means your roof won't degrade from corrosion across the region's 991 mm of annual rainfall and coastal moisture.

Yes. Aluminum expands and contracts smoothly with temperature swings, without the cracking, curling, or splitting that plague asphalt and wood shakes under freeze-thaw stress. With 83 freeze-thaw days per year in this region, that resilience is critical. The four-way interlocking panel design accommodates micro-movement while maintaining watertight seams. Unlike concrete tile or slate—which fracture when water freezes inside micro-cracks—aluminum's non-porous surface prevents water infiltration entirely. The Guardian Warranty explicitly covers cracking and curling for the original owner for life, and transfers for 50 years to the next owner. In Fundy–Albert's harsh seasonal climate, this is a rare guarantee.

No. Interlock metal roofing is warranted to resist sustained winds up to 120 mph (193 km/h) when installed to specification. Fundy–Albert's typical daily-max winds are about 21 km/h, with gusts reaching 125 km/h—well within design limits. The four-way interlocking aluminum panels lock to each other and to the fastening system, creating a unified, flexible structure that flexes rather than fails. This engineering has been proven on Antarctic research stations and coastal salt-air homes worldwide. Maritime Metal Roofing Ltd., your local installer since 2007, follows Interlock's spec precisely, ensuring full warranty coverage. Wind uplift is not a concern if installation is done correctly.

Structural reinforcement is almost never needed. Interlock's Shake profile installs at just 0.58 lb/sq ft, the Slate at 0.41 lb/sq ft, and the Mediterranean Tile—despite its authentic appearance—weighs only about 0.59 lb/sq ft. That Tile profile is roughly 96% lighter than real concrete or clay tile. Most homes in Fundy–Albert were already framed to carry slate or wood shake, so aluminum is a direct drop-in replacement that actually reduces load. The ICC-ES evaluation report ESR-1790 confirms compliance with IBC/IRC building codes. Installation over your existing roof is often possible, saving labor and disposal costs. Maritime Metal Roofing Ltd. will assess your specific structure at no charge.

No. Fundy–Albert receives about 991 mm of annual rainfall, yet metal roofing excels in wet climates because rain sheds instantly off smooth, hard aluminum. Unlike asphalt shingles, which absorb water and degrade, or wood shakes, which rot, aluminum is non-porous. The four-way interlocking panels create overlapping seams that funnel water down and out. Solid deck and underlayment (installed per spec) dampen sound and add a secondary moisture barrier, making metal roofing as quiet and leak-proof as asphalt. The Guardian Warranty covers leaks caused by material defect for life. After 80+ consecutive years of testing since 1998 manufacture in Delta, BC, Interlock's track record in high-rainfall regions is proven.

Interlock metal roofing achieves UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty covers perforation from hailstones up to 1.5 inches. This exceptional rating often qualifies homeowners for insurance premium discounts; contact your provider with the UL 2218 certification. Coastal maritime climates like Fundy–Albert's do experience hail, but aluminum's hardness and the interlocking design distribute impact forces across multiple panels. Unlike asphalt shingles, which tear and puncture easily, or slate, which shatters, aluminum dents but does not perforate under typical hail conditions. The Class 4 rating means Interlock panels withstand impacts that would destroy competitor products. Check your policy—many insurers recognize this durability advantage.

Metal roofing costs more upfront than asphalt, but over 50+ years, it is the last roof you buy. Asphalt shingles last 15–20 years and end up in landfills; in that same time, you'll replace them 2–3 times. Interlock's lifetime limited warranty (transferable for 50 years) covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance. The Guardian Warranty means zero surprises. Factor in near-zero maintenance—no algae treatments, no gutter cleaning from decomposing shingles—and metal's energy efficiency (energy-efficient colors with 0.84 emissivity reduce cooling costs). In Fundy–Albert's 2813 annual sunshine hours, reflective coatings reflect heat that asphalt absorbs. Current regional promotion: interest-free payments for 3 months and save at least $2499 on installation. Lifetime cost-per-year is lower than asphalt.

Very little. Unlike asphalt shingles, which require algae treatments, gutter clearing of decomposed shingle granules, and moss prevention in wet climates, aluminum demands no chemical maintenance. Unlike wood shakes, which rot and split in freeze-thaw cycles or require regular staining, metal is inert. Snow sheds naturally without ice dam damage. Fundy–Albert's 991 mm of rain and 185 cm of snow won't degrade aluminum. A visual inspection every few years and clearing debris from gutters is sufficient. The CALGreen-verified design confirms reduced maintenance burden. Maritime Metal Roofing Ltd. can recommend cost-effective post-installation checks if desired. Over a 50-year lifespan, maintenance costs on metal are negligible compared to asphalt's cycle of repairs, treatments, and replacement.

Yes. Interlock aluminum is approximately 95% recyclable at end-of-life. Asphalt shingles, by contrast, are torn off every 15–20 years and sent to landfills by the millions of tons annually—a cycle repeated indefinitely. Aluminum panels, manufactured since 1998 in Delta, BC, will outlast multiple generations, eliminating that landfill burden. When eventually recycled, aluminum retains its value and properties; used aluminum scrap commands resale value. Asphalt does not. In Fundy–Albert's climate, where heavy snowfall and 83 freeze-thaw days stress roofing heavily, the 50+ year lifespan of metal means one installation, one removal, one recycling event—versus three asphalt cycles. The Guardian Warranty's transferability for 50 years further extends the roof's useful life. Metal roofing closes the tear-off-to-landfill loop.

Yes. Fundy–Albert averages about 185 cm of snow, 991 mm of rain, roughly 83 freeze–thaw days a year, with peak wind gusts near 125 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.
