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

Yes—aluminum's light weight (the Shake profile weighs just 0.58 lb/sq ft) means your home carries far less load from the roughly 195 cm of snow Petitcodiac receives annually, yet the interlocking four-way panels stay firmly seated and won't deflect under that weight. Snow sits on the smooth surface until it melts; if ice dams form during the 89 freeze-thaw days per year, Interlock's rigid panel structure prevents the sagging that invites pooling. You can add snow guards during installation if you prefer controlled shedding over eaves.

Aluminum's crystalline structure makes it immune to the splitting and cracking that plague wood, asphalt, and concrete tile during freeze-thaw stress. Petitcodiac experiences about 89 freeze-thaw cycles annually—the kind of stress that causes traditional roofing to fracture and leak. The 3105-H24 aluminum alloy (ASTM B209) is rated for precisely these conditions. The oxide layer that forms on aluminum actually heals itself when scratched, so micro-damage from thermal cycling never becomes a corrosion point.

The four-way interlocking panel design, combined with proper installation to spec, is warranted to resist wind speeds up to 120 mph (193 km/h). Petitcodiac's typical gusts reach 116 km/h, well within that margin. The Guardian Warranty explicitly covers wind performance, and the interlocking edges mean each panel braces its neighbors—no lifting, no peeling, no blow-offs. That's the kind of durability that matters when Atlantic fronts sweep through the region.

Asphalt requires replacement every 15–25 years; you'll reroof twice while Interlock stands for a lifetime. The Guardian Warranty is non-prorated—no degression clause—and transfers once to the next owner for 50 years of coverage. When you account for two asphalt tear-offs (and landfill fees), reroofing labor, and weather downtime, the all-in lifetime cost of metal is lower. This month, Maritime Metal Roofing is offering interest-free payments for 3 months and savings of at least $2499 on installation, making the transition even sharper.

The Guardian Warranty is a lifetime limited, non-prorated material warranty for you (the original owner), covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It's one-time transferable: the next owner receives 50 years of coverage from completion. No prorating means claims remain valid at full value throughout your ownership. That transferability also boosts resale appeal—buyers inherit decades of protected roofing without worry.

Interlock achieves UL 2218 Class 4 impact rating—the highest available. The warranty explicitly covers perforation from hailstones up to 1.5 inches. Class 4 means survival of 2-inch steel balls dropped from 20 feet; severe hail in Atlantic Canada rarely exceeds that threshold. While minor denting is cosmetically possible in extreme events, structural integrity and leak protection remain intact. Many insurers recognize the Class 4 rating and may offer premium reductions—worth confirming with your agent.

Metal roofing requires virtually no maintenance. Asphalt needs moss treatment, shingle replacement, and gutter clearing every few years; wood shingles demand annual inspection and treatment. Interlock's aluminum and fluorocarbon coating resist algae, moss, and weathering. Rain (Petitcodiac averages 943 mm per year) naturally cleans the surface. A visual inspection every 5–10 years is sensible, but repairs are uncommon. The CALGreen-verified design acknowledges reduced maintenance burden—that translates to time and money back in your pocket.

No structural reinforcement is needed. The Interlock Tile profile weighs about 96% less than concrete or clay tile—roughly 0.59 lb/sq ft—and installs directly over most existing asphalt roofs. Your home's current structure is engineered to support asphalt; aluminum is a fraction of that load, leaving your framing untouched and saving the cost and mess of a full tear-off. The ICC-ES evaluation report ESR-1790 confirms this lightweight performance under code, meaning you can go metal without hiring a structural engineer.

Installation typically spans 3–7 days depending on roof size and complexity; Maritime Metal Roofing will confirm a timeline during your consultation. Yes, installation over existing asphalt is standard—no tear-off required, which cuts debris, labor costs, and project disruption. The lightweight aluminum (half the weight of traditional tile) means no structural prep work. Maritime Metal Roofing has served the Greater Moncton region since 2007 and handles the full process from inspection through warranty registration, keeping the job simple and local.

No. The four-way interlocking edges form a continuous seal that sheds water before it reaches the deck. Rain (943 mm annually in Petitcodiac) flows down and off; the overlap geometry means water cannot pool or back up. Solid deck and quality underlayment create the final barrier. Metal roofs outperform asphalt in heavy rainfall because the smooth surface sheds water cleanly, and the interlocking system eliminates the gap problems that plague shingles. Properly installed Interlock roofing by Maritime Metal Roofing is leak-proof in any weather the region throws at it.
