How much does a new roof cost in New Brunswick in 2026?

A full roof replacement on a typical New Brunswick home costs $8,000-$18,000 for architectural asphalt shingles or $15,000-$35,000 for metal roofing in 2026, with the wide range reflecting roof size, pitch, complexity, and existing conditions. Most NB homeowners with a standard 1,500-2,000 sq ft bungalow or two-storey will land in the $10,000-$14,000 range for a quality asphalt shingle job using 30-year architectural shingles.

The biggest driver of roofing cost in NB is the roof area, measured in roofing squares (one square equals 100 sq ft of roof surface). A 1,500 sq ft bungalow might have 1,800-2,200 sq ft of actual roof surface once you account for slope — that's 18-22 squares. Installed costs for architectural asphalt shingles run approximately $4-$7 per sq ft in NB, so that same bungalow runs $7,200-$15,400 depending on the contractor, the shingle brand, and the complexity of the roof. A steep or complex roof with multiple valleys, dormers, skylights, or chimney flashing adds significantly to labour time and therefore cost.

Decking condition matters enormously. If your existing plywood or OSB roof deck is sound, the cost stays in the standard range. But many NB homes — particularly those with roofs that were layered over without full tear-off, or older homes with original skip sheathing — need partial or full deck replacement when the shingles come off. Replacing damaged decking adds $2-$4/sq ft for materials and labour, and on an older Fredericton or Saint John home, budget $1,000-$3,000 extra for decking contingency.

Ice-and-water shield membrane is not optional in NB — it's required by the National Building Code for the first two metres up from the eaves, and most quality contractors extend it further up the slope in regions with heavy ice damming. This waterproof membrane adds $0.50-$1.50/sq ft to the material cost but is genuinely essential for protecting NB eaves through 100+ freeze-thaw cycles annually. Cutting this step out is a red flag in any roofing quote.

Valley flashing, step flashing around chimneys and dormers, and drip edge at eaves and rakes should all be itemized in your quote. These aren't extras — they're fundamental to a watertight roof. Replacing all flashings during a re-roof is the right call; trying to save money by reusing old flashings usually results in a leak within 2-3 years.

Labour costs in NB are lower than in Toronto or Vancouver — you'll pay less here for the same job, roughly 10-20% below major urban markets. However, material costs are close to national average since building products are shipped into the province. Northern NB (Edmundston, Campbellton, Bathurst) may see slightly higher quotes due to travel costs for contractors based in the larger southern centres.

Timing affects pricing. Spring and early summer are peak season when roofing crews are busiest — demand is high after NB winters reveal their toll. If your roof can wait until September or October, some contractors offer off-peak pricing. That said, a failing roof should never wait for a better price.

Always get at least three written quotes that specify the shingle brand and weight, number of layers being stripped, decking inspection and replacement policy, ice-and-water shield coverage, flashing replacement, clean-up and disposal, and warranty terms. The cheapest quote that skips any of these line items is rarely the best value. And always confirm your roofing contractor carries WorkSafeNB coverage — a written clearance letter before they start work protects you from liability if someone is injured on your property.
