Metal Roofing in Hubbards, Nova Scotia

Yes—aluminum's crystalline structure actually thrives in freeze-thaw climates. Unlike asphalt, which becomes brittle and cracks after Hubbards' typical 86 freeze-thaw days per year, aluminum expands and contracts without degradation. The roofing-grade 3105-H24 alloy won't split, crack, or curl the way wood shakes or concrete tile do. Your coating—a 30-year warranted Alunar fluorocarbon finish—seals the metal itself, so moisture never penetrates the substrate where freeze damage begins. After 26 years of installations from coastal British Columbia to Antarctica's research stations, freeze-thaw failure is simply not part of Interlock's warranty history.

Aluminum cannot rust because it contains no iron—the element that oxidizes and corrodes. What happens instead is that aluminum naturally forms a microscopic oxide layer that actually protects the metal beneath, and this layer self-heals when scratched. Hubbards sits on the South Shore where salt spray from Atlantic gales is a real concern, which is exactly why Interlock applies Alunar 70% PVDF fluorocarbon coating to both sides of every panel. That dual-side protection is unusual in the industry and crucial near saltwater. The coating itself carries a 30-year warranty against fading and chalking under ASTM D4214 testing. Combined with aluminum's corrosion immunity, you get a roof engineered for coastal life.

Metal roofing sheds snow and ice far better than asphalt because its smooth, hard surface prevents adhesion. Hubbards averages about 147 cm of snow yearly, and when spring sun arrives (you get roughly 2698 sunshine hours annually across the region), snow slides cleanly rather than forming dam-prone layers. The four-way interlocking panels lock together so tightly that no gaps allow ice and meltwater to penetrate, even during the multiple freeze-thaw cycles typical in your area. Snow guards are optional—many owners install them to direct slides away from walkways—but they're not needed for roof integrity. The metal itself is so light (the Shingle profile weighs just 0.41 lb/sq ft) that snow load is never a structural concern, so no expensive reinforcement is necessary.

Completely. Hubbards experiences gusts up to 132 km/h, and Interlock's four-way interlocking panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. That's the engineering margin you need for a roof that sits above the Atlantic. The interlocking mechanism—not fasteners alone—distributes wind load across the entire panel system, so panels won't lift or separate. UL 2218 Class 4 impact rating confirms the panels' structural integrity under extreme conditions. Maritime Metal Roofing Ltd., your local installer since 2007, knows exactly how to secure panels to withstand regional wind patterns. A metal roof won't flap, rattle, or peel up in the storms that do blow through.

Interlock achieves UL 2218 Class 4 hail impact rating—the highest available—and the warranty even covers perforation from hailstones up to 1.5 inches. That's exceptional protection. Many insurers recognize this and offer premium reductions (typically 10–15%) for metal roofs with Class 4 ratings because claims are so rare. Before installation, ask your insurer about metal roof discounts; your premium savings could offset a meaningful portion of the installation cost. Aluminum's hardness also means minor hail leaves no permanent dents the way softer asphalt or wood does. Over Hubbards' rainfall and weather patterns (1257 mm rain, 147 cm snow, 86 freeze-thaw cycles yearly), this durability translates to genuine cost savings and peace of mind.

Interlock's four-way interlocking design creates a continuous watertight envelope—panels overlap and interlock on all four sides, so water flows outward and downward with nowhere to pool or seep. With Hubbards averaging 1257 mm of rain annually, this design is critical. The panels are installed over solid decking and underlayment (typically ice and water shield), so the entire system mimics traditional asphalt in its leak-prevention approach but with superior durability. Aluminum itself never rots or develops the soft spots that allow slow leaks in wood-based roofs. Gutters and flashing are sealed using the same time-tested methods roofers have used for decades. The result: rain stays outside, attic stays dry.

Almost none. Metal roofing requires no annual inspections, no seal-coat reapplication, no moss or algae treatment, and no preventive repairs the way asphalt shingles do after a decade. You might rinse off salt spray or pollen occasionally if you live near the ocean, but that's optional—Hubbards' regular rainfall (1257 mm yearly) naturally cleans the surface. Compare this to asphalt, which needs inspection every 3–5 years, or wood shakes, which need regular treatment against rot and insects. Interlock's CALGreen certification specifically recognizes its reduced-maintenance profile. Over a 50-year lifespan, the time and cost savings are enormous. Your attention goes elsewhere while the roof simply performs.

Yes—metal roofing is the last roof you'll buy. Asphalt needs replacement every 20–25 years; metal lasts 50+ years with zero material degradation. Over five decades, you're looking at replacing asphalt twice (plus disposal costs) while your metal roof is still functioning with the same non-prorated warranty coverage. Add near-zero maintenance, potential insurance discounts, and the energy savings from energy-efficient colors (thermal emissivity 0.84, solar reflectance up to 0.55), and the math favors metal from year 20 onward. Current regional promotion offers interest-free payments for 3 months and savings of at least $2499 on installation—a real opportunity to offset first-cost. Maritime Metal Roofing Ltd. can walk you through financing that spreads the investment across the years you're not replacing asphalt.

Yes. Because Interlock panels are extraordinarily light—the Mediterranean Tile profile weighs just 0.59 lb/sq ft, about 96% lighter than concrete or clay tile—they install directly over existing asphalt without structural reinforcement. This saves thousands in tear-off and disposal costs, eliminates the landfill waste of old shingles, and shortens the installation timeline. Underlayment goes over the existing roof, then panels lock into place. Your attic stays protected throughout, and the acoustic layer of your existing roof plus new underlayment means the rain sound inside is indistinguishable from asphalt-quiet. Maritime Metal Roofing Ltd. will assess your specific roof during a site visit to confirm the existing structure can carry the lightweight load, but in the vast majority of Hubbards homes, no additional framing is needed.

The Guardian lifetime limited warranty covers the original owner for life against rusting, rotting, splitting, cracking, curling, and loss of impact resistance—basically, all the failure modes that afflict other roofing materials in climates like yours. It's non-prorated, meaning full coverage never decreases, and it transfers once to the next owner, who enjoys 50 years from completion. That transferability strengthens resale appeal and demonstrates Interlock's confidence in the product. The Alunar coating adds its own 30-year warranty specifically against chalking and fading (measured per ASTM D4214 and D2244). For Hubbards homeowners facing 86 freeze-thaw cycles, 1257 mm rain, and 132 km/h gusts annually, this warranty isn't marketing—it's validation that the material survives exactly these conditions.
