Metal Roofing in Riverside-Albert, New Brunswick — Lifetime Interlock® Aluminum Shingles Installed Locally

Metal roofing sheds snow and ice more effectively than asphalt because the smooth, hard surface prevents water from refreezing into dams. Riverside-Albert receives about 172 cm of snow annually, and the 83 freeze-thaw days per year create conditions where ice damming—and the water damage it causes—is a real problem. Interlock's four-way interlocking panels stay flush and rigid, so meltwater moves down the slope instead of pooling under shingles. You can add snow guards where you need them, but the metal itself won't trap moisture that leads to rot and premature failure.

Aluminum doesn't absorb water, so freeze-thaw cycles that crack asphalt, wood, and concrete have no effect on it. Riverside-Albert experiences roughly 83 freeze-thaw days yearly, plus 1117 mm of rain and 172 cm of snow—conditions that destroy most roofing materials over time. Interlock's roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209) expands and contracts predictably without weakening, and the Alunar 70% PVDF fluorocarbon coating (warranted 30 years) protects against salt air and weather extremes. This is why Interlock panels have been installed from coastal salt-air homes to Antarctic research stations since 1998.

Aluminum cannot rust because it contains no iron—iron is what oxidizes and turns brown. When aluminum's oxide layer gets scratched, it self-heals in minutes, sealing the new surface. Steel roofing, by contrast, rusts from the inside out once its coating is breached. Riverside-Albert's coastal humidity, salt air on the Fundy Coast, and 1117 mm of annual rainfall make this distinction critical. Interlock applies Alunar 70% PVDF fluorocarbon finish to both sides of the panel for extra protection, giving you a non-rusting roof that stays sound for decades even in marine environments.

Yes—Interlock's four-way interlocking panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to spec. Riverside-Albert's typical daily-max winds average 22 km/h, with gusts reaching 147 km/h, putting it well within the warranty limit. The interlocking design prevents uplift at seams and edges, which is where asphalt shingles fail first. A solid metal roof fastened correctly won't lift or peel in a storm; water and debris can't get underneath because there's no gap to exploit.

Interlock earns 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 rating means the roof passes tests that simulate severe hail and retains its impact resistance over time. Many homeowners see lower insurance premiums because metal roofing is more resistant to damage than asphalt; your insurer may offer a discount that partially offsets the roof cost. Check with your agent, but the durability is verified and backed by a transferable 50-year warranty for the next owner.

Metal roofing sheds water faster than asphalt because rain runs off the hard surface instead of soaking in. Interlock's interlocking panels overlap four ways, creating a labyrinth that water cannot penetrate; any moisture that reaches a seam is diverted downslope. Riverside-Albert's annual rainfall of 1117 mm, combined with 172 cm of snow melt, puts constant pressure on your roof. Asphalt absorbs water, ages faster under wet conditions, and develops pinhole leaks after 15–20 years. Metal panels won't absorb anything; if installed to spec by a trained installer like Maritime Metal Roofing Ltd., they'll stay dry underneath.

Yes—Interlock's Mediterranean Tile profile installs at only 0.59 lb per square foot, making it about 96% lighter than concrete or clay tile. Your home's frame doesn't need reinforcement, and most existing roofs can handle the metal panels directly without tear-off, saving thousands in labor and waste. Even the Shake profile weighs just 0.58 lb/sq ft. Asphalt shingles average 2–3 lb/sq ft; adding metal is often a net weight reduction, especially on older homes where structural capacity is a concern. Maritime Metal Roofing Ltd. will assess your roof and advise whether underlayment or decking work is needed.

The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner—covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It's also one-time transferable, giving the next owner 50 years from completion. Unlike asphalt shingles, which typically last 15–20 years and require tear-off every cycle, metal roofing lasts 50+ years, ends the cycle of replacement and landfill waste, and transfers value to the next owner. The Alunar coating itself is warranted 30 years against chalking and fading (measured per ASTM D4214 and D2244). This is the last roof you'll install—or the last one before a major life event.

Metal roofing requires almost no maintenance—no patching, no replacing individual shingles, no clearing debris that traps moisture. Asphalt shingles need inspections every few years and repairs to curled, missing, or cracked shingles; wood shakes split and require treatment or replacement. Interlock's aluminum is corrosion-proof, and the Alunar 70% PVDF coating resists chalking and fading over 30 years. A rinse with plain water once yearly removes dirt; you're done. Riverside-Albert's 2770 sunshine hours and frequent freeze-thaw cycling will age asphalt visibly, but metal stays sound and appearance-stable. Maritime Metal Roofing Ltd. recommends light inspection after severe weather, but routine maintenance is minimal.

Metal roofing is approximately 95% recyclable, and when it eventually reaches end-of-life, the aluminum retains value and can be melted and reformed into new products indefinitely. Asphalt shingles, by contrast, are nearly impossible to recycle; most tear-offs go directly to landfill. Over a 50-year period, a metal roof eliminates three full asphalt replacements, three tear-offs, and three landfill deposits. Interlock has been manufactured in Delta, BC, since 1998, keeping the supply chain local and minimizing transport emissions. Choosing metal breaks the cycle of replacing and discarding; it's CALGreen-verified for reduced maintenance, and the one-time installation means no perpetual waste stream.
