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

Yes—aluminum's smooth, hard surface sheds snow and ice far more effectively than asphalt shingles, reducing ice dam formation. With about 193 cm of snow annually and roughly 86 freeze-thaw days per year in the Fredericton Capital Region, your roof faces constant cycles of melting and refreezing. Interlock's four-way interlocking panels create a unified surface that won't cup or split under repeated freeze-thaw stress, unlike wood shingles or asphalt. Snow guards can be installed to manage controlled release. The warranty even covers ice-dam-related damage, giving you protection through winter after winter.

Aluminum expands and contracts uniformly with temperature swings, and unlike brittle materials, it doesn't crack or splinter under stress. Harvey's climate averages about 86 freeze-thaw cycles annually with mean temperatures around 6.5°C, creating constant expansion pressure on roofing materials. Interlock panels are engineered to flex slightly without permanent deformation, and the roofing-grade 3105-H24 aluminum alloy (ASTM B209) retains impact resistance even after decades of cycling. Asphalt becomes brittle in cold and crumbly in heat; wood splits and curls. Aluminum simply moves and returns to shape, year after year.

No—aluminum cannot rust because it contains no iron. With about 978 mm of annual rainfall in the region, rust resistance is critical, and aluminum's oxide layer forms a natural, self-healing protective barrier. If scratched, the layer reforms automatically, unlike steel roofing. Interlock panels are finished with Alunar® 70% PVDF fluorocarbon coating applied to both sides, warranted 30 years against chalking and fading (ASTM D4214/D2244). This two-sided protection is especially valuable in coastal or damp climates; the coating guards against salt air and moisture while the aluminum beneath offers intrinsic corrosion immunity. You'll never paint or treat your roof for rust.

Yes—Interlock panels are warranted to resist wind speeds up to 120 mph (193 km/h), and Harvey's typical gusts reach about 124 km/h. The four-way mechanical interlocking system locks each panel to its neighbors on all sides, distributing wind load across the entire roof rather than relying on fasteners alone. This redundancy is why the warranty covers the design itself, not just installation. Over typical regional gusts and occasional storm winds, the interlocking design means your roof won't flutter, rattle, or lift at seams. Installation to spec by Maritime Metal Roofing Ltd. ensures every panel is seated and locked correctly for full wind protection.

Interlock achieves UL 2218 Class 4, the highest hail-impact rating available—tested against 1.5-inch ice balls. The warranty even covers perforation from hailstones up to that size. Many insurers recognize Class 4 ratings and offer premium discounts for non-combustible, impact-resistant roofing. With the region's exposure to severe weather and hail's unpredictability, this rating transfers real financial confidence: one claim under your current roof could exceed $10,000 in repairs, while Interlock's impact resistance and warranty protection shift that risk away. Ask your insurance broker about eligible discounts when you're comparing cost; the savings often offset a portion of the upgrade investment.

No structural reinforcement is needed. Interlock's Slate profile installs at about 0.41 lb/sq ft, the Shake at 0.58, and the Mediterranean Tile at roughly 0.59 lb/sq ft—making the Tile profile about 96% lighter than concrete or clay tile. Most existing homes are over-engineered for asphalt (which weighs 1.5–3 lb/sq ft), so switching to aluminum actually reduces structural stress. You can often install Interlock directly over an existing asphalt roof without tearing it off, saving labor, time, and landfill waste. Maritime Metal Roofing Ltd. will assess your roof during the free estimate and confirm whether over-laying is feasible; if it is, your installation stays simple and fast.

Metal roofing costs more upfront than asphalt but becomes your last roof purchase, whereas asphalt requires full replacement every 15–25 years. Over 50 years, Interlock's lifetime limited warranty (transferable to the next owner for 50 years from completion) saves tens of thousands in replacement labor, tear-off fees, and landfill disposal. With about 978 mm rain and 193 cm snow annually in Harvey, your asphalt roof endures constant moisture stress and freeze-thaw cycling—both accelerate granule loss and cracking. Metal outperforms by decades. Current promotions include interest-free payments for 3 months and at least $2,499 in savings on installation, lowering that initial gap. Calculate total cost-of-ownership over 50 years, not sticker price.

Very little—one of metal's strongest advantages. Asphalt shingles require regular inspection for granule loss, cracking, and algae; wood shakes need cleaning, re-staining, and replacement of split pieces every 5–10 years. Interlock aluminum requires occasional inspection (no more than annually) and clearing of debris from gutters and valleys. The Alunar® finish resists fading and chalking for 30 years, and the non-porous surface doesn't trap moss or algae the way shingles do. Snow in Harvey's climate (about 193 cm yearly) sheds naturally off the smooth surface. No coating touch-ups, no wood treatment, no seasonal repairs. Over the roof's 50-year life, your maintenance cost approaches zero compared to decades of patches and treatments on asphalt or wood.

Interlock's Guardian Warranty is lifetime limited for the original owner—non-prorated material coverage for rusting, rotting, splitting, cracking, curling, and loss of impact resistance. When you sell, it transfers to the next owner for 50 years from completion, a significant resale asset. The roof itself typically lasts 50–70+ years with minimal degradation; the Alunar® coating is warranted 30 years against fading and chalking (ASTM D4214/D2244 tested). In Harvey's freeze-thaw climate (about 86 cycles annually), this longevity shines: asphalt becomes brittle and splits within 20 years, while Interlock's aluminum flexes and holds. The ICC-ES evaluation (ESR-1790) confirms structural integrity over time. You're buying a roof that will outlast your mortgage and still protect the next owner.

Yes—Interlock panels are approximately 95% recyclable, ending the asphalt tear-off-to-landfill cycle. At end-of-life, aluminum retains scrap value and re-enters the supply chain indefinitely without degradation. Asphalt shingles, by contrast, are discarded and rarely recycled; millions of tons accumulate in landfills annually. Since Interlock installs over most existing roofs (the Tile profile weighs only 0.59 lb/sq ft, about 96% lighter than concrete or clay), you avoid the labor, waste, and emissions of a tear-off and haul-away. Over 50+ years, one metal roof prevents multiple asphalt replacements, each with its own tear-off waste. The material is CALGreen-verified for reduced maintenance. If environmental impact matters to you, metal roofing transforms your home into a zero-waste-to-landfill system.

Yes. Harvey averages about 193 cm of snow, 978 mm of rain, roughly 86 freeze–thaw days a year, with peak wind gusts near 124 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.
