Metal Roofing in St. Stephen, New Brunswick — Lifetime Interlock® Aluminum Shingles Installed Locally

Yes — aluminum's oxide layer actually strengthens through repeated freezing and thawing rather than degrading. Your area experiences about 90 freeze-thaw days annually, where traditional asphalt shingles crack and curl from thermal stress. Interlock's 3105-H24 aluminum alloy expands and contracts uniformly without embrittlement, and the four-way interlocking design prevents moisture infiltration that causes material failure. The Guardian warranty covers cracking and curling for the lifetime of your ownership.

The aluminum sheds snow more efficiently than asphalt because its smooth, low-friction surface prevents dangerous ice-dam buildup. St. Stephen averages about 151 cm of annual snowfall with mean winds near 18 km/h, which means wet, heavy snow loads — exactly where asphalt roofs fail first. Interlock panels weigh only 0.41–0.59 lb/sq ft depending on profile, so no structural reinforcement is needed even in snow-heavy regions. Snow guards are available and install directly into the four-way interlocking seams for safe, code-compliant retention.

St. Stephen receives about 1021 mm of rainfall annually, and Interlock's four-way interlocking panels overlap in two directions, channeling water downslope with no exposed fasteners or seams in the water path. Installation over a solid deck with underlayment (standard practice by Maritime Metal Roofing Ltd.) creates the same watertight seal asphalt offers — metal roofing doesn't leak when installed correctly. The ICC-ES ESR-1790 evaluation confirms that aluminum panels meet building code water-management requirements for coastal and high-rainfall climates.

Absolutely. Your area experiences gusts up to 129 km/h, and Interlock panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. The four-way interlocking design — where each panel locks on top, bottom, and both sides — creates a continuous structural skin that distributes wind load across the entire roof rather than stressing individual fasteners. UL testing confirms this geometry outperforms standing-seam designs in high-wind environments. Maritime Metal Roofing Ltd. ensures every installation meets these engineering standards.

No significant damage — Interlock achieves UL 2218 Class 4 impact rating, the highest available, with warranty coverage even for 1.5-inch hailstones. Many insurers offer premium discounts for Class 4 metal roofing because claims are rare; contact your provider with the UL 2218 rating to explore savings. Aluminum's dent resistance combined with its non-combustibility (Class A fire classification available) and durability means underwriters view metal roofs as lower-risk assets. In St. Stephen's climate, a roof that won't require replacement for 50+ years eliminates repeated insurance claims.

Aluminum contains no iron — rust is iron oxide, so chemically it cannot form. Within hours of exposure, aluminum develops a microscopic oxide layer that protects the underlying metal; when scratched, that layer self-heals. Interlock panels use roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209), coated on both sides with Alunar 70% PVDF fluorocarbon finish (30-year warranty against chalking). In St. Stephen's 151 cm annual snowfall with road salt and coastal moisture influence, steel roofs corrode within 10–15 years; aluminum stays structurally intact for 50 years and beyond.

Yes — Interlock Mediterranean Tile installs at only 0.59 lb/sq ft, about 96% lighter than concrete or clay tile, so no structural reinforcement is required. Comparison: concrete tile runs 15–20 lb/sq ft and forces costly joist upgrades. You can install directly over most existing asphalt roofs, saving thousands in tear-off labor and landfill fees. Maritime Metal Roofing Ltd. assesses your roof deck during the free estimate to confirm whether a direct-over installation is code-compliant for your home — often it is, making the entire project faster and more affordable.

energy-efficient Interlock colors reflect rather than absorb solar heat, with initial reflectance up to 0.55 and thermal emissivity of 0.84, reducing cooling load by 10–25% depending on color and climate. St. Stephen receives about 2946 sunshine hours annually — enough to make reflective coatings measurable year-round. Lighter profiles like Slate or Cedar Shingle qualify for the Cool Roof Rating Council program. Over a 50-year roof life, the cooling savings compound, especially if you add insulation during installation. The Guardian warranty covers the coating for 30 years, protecting that reflectance advantage.

Yes, when you calculate total cost of ownership over 50 years. Asphalt roofs cost $8–12/sq ft and last 15–20 years, requiring 2–3 full replacements plus recurring tear-off and landfill fees. Interlock costs more upfront but lasts 50+ years under The Guardian's lifetime limited, non-prorated warranty; the next owner inherits 50 years of coverage too, protecting resale value. Current regional promotion: interest-free payments for 3 months plus at least $2499 savings. Once you account for zero replacement cycles, no labor-intensive maintenance, and avoided landfill disposal, aluminum is the last roof you'll buy.

Virtually none. Unlike asphalt (which requires sealing and granule replacement every 3–5 years), wood shakes (which rot, split, and need chemical treatment), or tile (which cracks and requires periodic re-pointing), Interlock aluminum needs only occasional gutter cleaning and visual inspection. The Alunar fluorocarbon coating is CALGreen-verified for reduced maintenance and carries a 30-year warranty against chalking or fading per ASTM D4214 and D2244 standards. With 151 cm annual snowfall and 90 freeze-thaw days, most roofing materials fail through repetitive weather stress; aluminum's oxide layer self-heals, eliminating the maintenance cycle that defines other materials.

Yes. St. Stephen averages about 151 cm of snow, 1021 mm of rain, roughly 90 freeze–thaw days a year, with peak wind gusts near 129 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.
