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

Interlock panels shed snow and ice faster than asphalt because aluminum's smooth surface and thermal properties reduce ice adhesion—especially important when you're getting roughly 185 cm of snow annually. The four-way interlocking system keeps panels locked together under load, preventing separation. Optional snow guards can be installed where needed to manage slides safely. The lightweight design (about 96% lighter than concrete tile) means your existing structure handles the snow weight without reinforcement, and there's no risk of panel failure from freeze-thaw stress like heavier materials face during Hillsborough's typical 83 freeze-thaw cycles per year.

Aluminum has no iron content, so it cannot rust or corrode as temperatures swing between freezing and above-zero during Hillsborough's 83 annual freeze-thaw days. Asphalt becomes brittle in cold and soft in relative warmth, leading to cracking and curling. Interlock's 3105-H24 and 3003-H24 aluminum alloy maintains structural integrity through those cycles because its oxide layer self-heals when scratched—no exposed metal to degrade. With 185 cm of snow melt and about 991 mm of rain yearly, your roof faces constant moisture exposure, making material stability critical; aluminum's chemistry simply doesn't change with temperature the way petroleum-based asphalt does.

No—the four-way interlocking seam design sheds roughly 991 mm of annual rainfall as fast as water hits the panel. Each panel locks to its neighbors on all sides, so water has no path into the seam itself. Installation over a solid deck with underlayment (standard here) creates the same watertight envelope as asphalt, but without asphalt's vulnerability to UV degradation and shrinkage cracking. The ICC-ES ESR-1790 evaluation confirms the system meets building code water management requirements. Leaks in metal roofs almost always trace to poor flashing at penetrations—a roofing detail issue, not a metal roof weakness—and Maritime Metal Roofing's 17-year track record in this region reflects their understanding of proper installation.

Yes—gusts up to 125 km/h are typical in your area, and Interlock's warranty covers wind speeds up to 120 mph (193 km/h) when installed to specification. The four-way interlocking panels lock together so tightly that wind cannot lift or separate them the way it can with shingles. Each panel grips its neighbor mechanically, not adhesively, so the connection actually strengthens under lateral pressure. The system's light weight (0.41 to 0.59 lb/sq ft depending on profile) reduces the moment arm that wind exploits, and the low profile of designs like Slate and Cedar Shingle presents less sail area than traditional dimensional shingles or standing seam.

Aluminum contains no iron, so it cannot rust under any conditions—a fundamental material difference from steel, which oxidizes when exposed to moisture and salt-air conditions. Interlock's Alunar fluorocarbon finish (70% PVDF, applied to both sides of every panel) adds a 30-year warranted coating layer, but even if that coating were removed, the base aluminum would not corrode. Steel requires constant maintenance and eventually fails in salt-influenced air; aluminum's oxide layer self-heals when scratched, giving it true passive durability. While Hillsborough sits in the Greater Moncton region rather than coastal salt spray, the combination of 991 mm rain, 185 cm snow melt, and typical 21 km/h winds creates perpetual moisture exposure that favors a non-ferrous material.

Metal roofing costs more initially, but you're buying your last roof—asphalt lasts 15–20 years and requires two to three replacements in a home's lifetime, each with tearoff labor and landfill fees. Interlock's lifetime limited warranty (non-prorated for the original owner, transferable to the next owner for 50 years from completion) eliminates replacement costs. Over 50 years, a single metal roof installation saves thousands in labor and material versus multiple asphalt cycles. Current promotion: interest-free payments for 3 months and at least $2499 in savings on installation. No algae cleaning, no granule loss in 185 cm of snow runoff, no brittle cracking in your 83 annual freeze-thaw cycles—lower maintenance cost compounds the value.

Essentially none beyond the gutter cleaning you already do. Metal panels don't degrade, split, curl, or lose protective coating the way asphalt shingles do after Hillsborough's harsh winters and 185 cm of annual snowfall. There's no algae growth, no granule shedding into gutters, and no need for seasonal inspections to catch deterioration. The 30-year Alunar fluorocarbon coating (ASTM D4214 / D2244 measured) resists chalking and fading through decades of exposure to 2813 annual sunshine hours and temperature extremes. If moss ever grows on the panel (rare in your climate), a rinse with a garden hose solves it. Compare that to asphalt, which requires regular inspection for missing shingles, cracking, and granule loss—especially after heavy snow and freeze-thaw stress.

Yes—Interlock metal roofing carries a UL 2218 Class 4 impact rating, the highest available, and the warranty even covers perforation from hailstones up to 1.5 inches. Class 4 rating often qualifies homeowners for insurance premium reductions; contact your insurer with the UL 2218 rating documentation and your warranty details. The non-combustible aluminum and superior impact resistance make it a lower-risk proposition than asphalt from an underwriting standpoint. While Hillsborough's climate data don't suggest hail as a dominant risk, the added protection costs nothing and can offset the installation investment through insurance savings over just a few years.

Yes—Interlock offers five profiles: Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile, each with authentic dimensional texture and shadow lines. Slate and Cedar Shingle suit traditional homes; Shake adds visual depth and movement; Mediterranean Tile replicates clay or concrete tile weight (but weighs only ~0.59 lb/sq ft, about 96% lighter). Standing Seam suits contemporary and industrial aesthetics. Each profile is manufactured from the same roofing-grade 3105-H24 and 3003-H24 aluminum alloy, so you're not trading durability for appearance. Color options include energy-efficient choices, so you can match regional aesthetics—whether your neighborhood leans farmhouse or modern—while keeping cooling costs down through reflective coatings.

energy-efficient Interlock colors reflect heat that asphalt absorbs, reducing attic and cooling loads during Hillsborough's approximately 2813 sunshine hours per year. Measured thermal emissivity reaches 0.84, and initial solar reflectance up to 0.55 (Aged Copper Penny), meaning less solar energy converts to heat inside your home. Cool Roof Rating Council validation confirms this performance under real-world conditions. Summer savings depend on roof color, ventilation, and cooling system efficiency, but lower attic temperatures extend HVAC lifespan and reduce peak demand charges. In a climate with 185 cm of snow and 83 freeze-thaw days, you're not cooling aggressively year-round, but spring and fall savings accumulate, and the reflective coating also reduces thermal stress on the panels themselves, supporting the warranty's longevity claims.

Yes. Hillsborough 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.
