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

Metal roofs shed snow and ice far better than asphalt because the smooth, hard surface offers no grip—snow slides off in the spring thaw instead of pooling and refreezing. Hartland averages about 230 cm of snow annually and roughly 80 freeze-thaw days per year, which turns asphalt brittle and causes shingles to cup and crack. Interlock's four-way interlocking aluminum panels stay rigid through those cycles because aluminum's oxide layer doesn't degrade from repeated freezing; the material simply doesn't rot or split. Snow guards are available if you want controlled slides, but the lightweight design—Shake profile at just 0.58 lb/sq ft—means no structural strain from snow load either.

Aluminum cannot rust because it contains no iron, which is what oxidizes and creates rust. Instead, aluminum develops a thin oxide layer that actually protects the metal beneath—and when that layer is scratched, it self-heals in hours. Interlock uses roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209) with a Alunar 70% PVDF fluorocarbon finish applied to both sides of every panel, giving you 30 years of warranted protection against chalking and fading. For Hartland, where about 1010 mm of rain falls yearly and winter moisture is constant, this means zero rust staining on your gutters, fascia, or siding—something steel roofing owners deal with for the roof's entire life.

No. Freeze-thaw cycles damage asphalt and wood because water soaks into them, freezes, expands, and cracks the material from inside. Aluminum is non-porous—water cannot soak in—so there's nothing to freeze and split. Hartland experiences roughly 80 freeze-thaw days yearly, meaning frequent temperature swings that would normally destroy asphalt shingles in five to ten years. Interlock panels stay dimensionally stable through these cycles because the material simply doesn't absorb moisture. The four-way interlocking design also ensures water runs off quickly; there's no pooling that could refreeze at the seams. This durability is part of why The Guardian warranty covers the original owner for life against splitting and cracking.

Heavy rain cannot penetrate properly installed metal roofing because the four-way interlocking panels overlap and guide water downslope like shingles, and the seams are sealed by the overlapping geometry itself—not tape or sealant that dries out. Hartland receives about 1010 mm of rainfall annually, often mixed with wet snow, so your roof must handle sustained moisture without fail. The ICC-ES evaluation report ESR-1790 confirms Interlock's panel design meets IBC and IRC standards for water management. Installation over a solid deck with underlayment (typical over existing roofs) adds a backup layer. The critical difference from asphalt: metal doesn't absorb water, so even if a seam shifts slightly over decades, the panel surface itself won't rot or degrade. Professional installation by Maritime Metal Roofing Ltd., serving this region since 2007, ensures proper slope and overlap.

No—in fact, metal roofing is dramatically lighter than the alternatives it mimics. Interlock's Mediterranean Tile profile weighs just 0.59 lb/sq ft, about 96% lighter than concrete or clay tile, so most homes need zero structural upgrades. Even the heavier Shake profile at 0.58 lb/sq ft is far lighter than asphalt over time because asphalt is denser and requires replacement every 15–20 years, whereas metal is installed once. For a typical Hartland home, installing metal over an existing asphalt roof is routine—no tearing down to bare wood, no reinforcing beams, no structural engineer consultation needed. This kept-in-place installation also means the existing roof provides a cushion for underlayment, which aids both thermal performance and noise dampening. Your contractor simply overlays and fastens.

The Guardian is a lifetime limited, non-prorated material warranty for you as the original owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance—the failures that plague asphalt and wood. It's transferable once to the next owner for 50 years from completion, which supports resale value. Unlike prorated warranties that pay out less each year, this one pays full replacement cost for the original owner's entire tenure. Because Hartland's climate involves about 230 cm of snow, frequent freeze-thaw (80 days/year), and nearly 1010 mm of rain, you need a warranty that doesn't expire the moment seasonal stress hits hardest. The 30-year coating warranty (ASTM D4214/D2244 tested) ensures color and gloss stability over Hartland's roughly 2823 annual sunshine hours without fading concerns.

Interlock's four-way interlocking panels are warranted to resist winds up to 120 mph (193 km/h) when installed to specification. Hartland's typical wind gusts reach about 117 km/h—right at the edge of severe, so a 120 mph rating gives you a safety margin. The overlapping design means each panel is locked to its neighbors on all four sides; wind cannot lift an edge or peel panels back. Unlike asphalt shingles, which can blow off in gusts around 75 mph, or single-lock metal panels that rely on fasteners alone, Interlock's geometry provides mechanical resistance independent of fastener count. Winter storms combined with the region's about 230 cm of snow load make this engineering critical—the panels won't separate or flutter during the heavy, wet gusts that often accompany spring thaw.

Metal requires virtually none. Asphalt shingles need regular inspections, algae cleaning in wet climates, and patching within 15 years; wood shakes require annual sealing and rot monitoring; tile needs regrouting and broken-piece replacement. Interlock aluminum panels need neither sealing, staining, nor treatment because the Alunar 70% PVDF coating is factory-applied to both sides and lasts 30 years, warranted against chalking and fading. Hartland's 1010 mm annual rainfall and 80 freeze-thaw days would accelerate deterioration in organic materials—but metal is inert. You rinse gutters to avoid debris damping (same as any roof), and that's it. CALGreen testing has verified Interlock for reduced maintenance, which means lower homeowner cost over the roof's life and zero emergency repairs for splits or rot, common in this region's moisture-heavy climate.

Metal roofing costs more upfront than asphalt—usually $15,000–$25,000 more for a typical home—but over 50+ years, it is the last roof you buy. Asphalt requires replacement every 15–20 years; in Hartland's climate with 80 freeze-thaw days and 230 cm of snow annually, lifespan skews toward the shorter end because freeze-thaw accelerates cracking. Three replacements over 60 years means three tear-off labor bills, three new underlayment costs, and three roof-off periods when your home is exposed. A single metal roof installed once eliminates that cycle. Current financing—interest-free for 3 months, with savings of at least $2499 on installation—reduces the cash-flow barrier. The lifetime Guardian warranty on materials plus energy savings from energy-efficient colors (0.84 thermal emissivity) mean your cost per year of protection is actually lower than asphalt by year 20.
