How much does a metal roof cost compared to shingles in New Brunswick?

In New Brunswick, metal roofing costs roughly two to three times more than asphalt shingles upfront — expect $8-$14/sq ft installed for standing seam metal versus $4-$7/sq ft installed for architectural asphalt shingles. On a typical NB home with 2,000 sq ft of roof surface, that translates to a $16,000-$28,000 metal roof versus an $8,000-$14,000 shingle roof. The premium is real, but so is the lifespan difference.

Standing seam metal — the best performer for NB's climate — sits at the higher end of that range at $10-$14/sq ft installed. This system uses concealed fasteners with vertical seams that interlock along the length of the panel, which is critical for NB's coastal wind and rain exposure. No exposed fasteners means no fastener penetrations to develop leaks as washers age and freeze-thaw cycles work screws loose over the years. Snap-lock and exposed-fastener corrugated metal panels start at $8-$10/sq ft and are a reasonable mid-range option on simpler roof geometries, but standing seam is worth the extra cost on a complex roof or a coastal NB property.

Steel is the most common metal roofing material in NB, typically Galvalume-coated steel with a factory paint finish. Aluminum costs more (add 15-25%) and is lighter and more corrosion-resistant — worth considering for Bay of Fundy coastal homes where salt air is a persistent concern. Copper is occasionally used for accent features on heritage homes in Saint John or Fredericton but is rarely used for full roofs given the premium cost ($25-$40/sq ft installed).

The cost comparison changes significantly when you think in lifetime terms rather than upfront terms. A quality asphalt shingle job in NB realistically lasts 18-25 years before replacement is needed. A properly installed standing seam metal roof carries a 40-50+ year lifespan — often exceeding the useful life of the building. Over a 50-year horizon, that $28,000 metal roof replaces itself once, while the $14,000 shingle job gets replaced two to three times at increasing material and labour costs. When you factor in reduced maintenance, lower insurance premiums that many NB insurers now offer for metal roofs, and the snow-shedding characteristics that reduce structural snow load in heavy northern NB winters, the lifetime math often favours metal despite the upfront premium.

Removal and disposal of existing roofing adds cost to either project. A standard shingle tear-off and disposal runs $1-$2/sq ft in NB — roughly $2,000-$4,000 on a typical home. Metal roofing can sometimes be installed directly over existing shingles (with proper furring strips for ventilation and drainage) when the deck is sound, which can eliminate tear-off costs and adds insulation value. Ask your metal roofing contractor whether a direct-over installation is appropriate for your specific situation.

Metal roofing also performs differently in NB winters in ways that affect the total cost picture. Metal sheds snow naturally rather than accumulating load, which is meaningful in northern NB regions that see 300+ cm annually. It essentially eliminates ice damming when properly installed, saving on the interior water damage and ice dam removal costs that plague shingle roofs in poorly ventilated NB homes. And metal's reflective surface reduces summer cooling loads, which while less critical in NB than in southern climates, is a real benefit.

Get quotes from contractors who specialize in metal roofing specifically — installation technique matters more with metal than with shingles, and a roofer primarily experienced with asphalt is not the right choice for a standing seam installation. Ask for references from metal roofing projects specifically, and check those references. For most NB homeowners planning to stay in their homes long-term, metal roofing is a serious conversation worth having with at least two or three experienced contractors.
