Cost Comparison: Asphalt vs Metal in Moncton (2026)
Asphalt shingle replacement in Moncton: $7,000–$15,000 for standard architectural shingles (IKO Cambridge, GAF Timberline HDZ, CertainTeed Landmark). Metal roofing: $18,000–$42,000 for standing-seam steel or steel shingles. The upfront cost difference is $10,000–$25,000.
Over 50 years, the picture changes: premium asphalt lasts 25–30 years in NB conditions, meaning one full replacement cycle. Metal lasts 40–50+ years with minimal maintenance. Factoring in one replacement, the 50-year total cost of asphalt approaches metal's upfront cost — making metal the better long-term value for homeowners planning to stay.
Snow Performance: Where Metal Wins Clearly
Standing-seam metal roofing has a significant practical advantage in Moncton's 200–300+ cm annual snowfall: it sheds snow naturally. The smooth surface and continuous panels mean snow slides off before it accumulates to dangerous loads. This eliminates the risk of ice dam formation at the eave entirely.
Asphalt shingles hold snow. This is by design — the granulated surface creates friction. But in Moncton's climate, this means snow builds up, melts from below (via heat loss), and creates ice dams. With proper insulation, ventilation, and ice & water shield, asphalt can perform reliably — but the risk is higher and requires more active management.
Salt Air and Freeze-Thaw Durability
Both materials perform in NB conditions when properly specified. Modern IKO and GAF architectural shingles are rated for NB climate zones and handle thermal cycling well for their rated lifespan. Metal roofing with Galvalume substrate and PVDF (Kynar) coating is specifically engineered for coastal salt-air environments like Greater Moncton and the Bay of Fundy corridor.
For homes in Sackville, Amherst NS, or anywhere near coastal salt air, PVDF-coated metal has a clear durability advantage over asphalt. For inland Moncton, Dieppe, and Riverview, both perform comparably when properly installed.
Which Should You Choose for Your Moncton Home?
Choose asphalt if: You're working with a tighter budget ($7k–$15k), the home may be sold within 10–15 years, or you want the widest colour selection and familiar aesthetics. GAF Master Elite or IKO Craftsman Premier certified installation with proper underlayment gives you 25–30 reliable years in NB.
Choose metal if: You plan to stay in the home long-term (10+ years), want to eliminate ice dam risk, live in a high-wind area (Sackville/Tantramar region), or want the one-and-done durability of a 40–50+ year roof. The higher upfront cost is a real investment, not just a premium.
