Metal roofing cost in Canada: what a 10 ft steel sheet costs at Quebec retailers

The table is the price of one 10 ft corrugated steel roofing sheet at each Quebec retailer, seen September 24, 2026. Matério is cheapest at $45.99 and Patrick Morin the priciest at $48.50, a gap of $2.51 per sheet (5.5 percent).

These are not copies of one sheet. A store may list a galvanized sheet and another a galvalume one, and the width, profile and gauge can differ from one listing to the next. Read the specification of the sheet you are buying before you decide a store is cheaper.

Compare the price per square foot of roof covered, not the price per sheet. A sheet is wider overall than the width it covers, because neighbouring sheets overlap. The effective width is on the manufacturer specification.

As a worked example, a 10 ft sheet with a 30 inch effective width covers 25 square feet. At that coverage the range above works out to $1.84 to $1.94 per square foot of roof. Your sheet may cover more or less, so run the same division with your own figure.

The sheet is only part of a metal roof. Budget for the screws with sealing washers, the ridge cap, the closure strips, the flashings and the underlayment. We do not track those yet, so we will not quote them.

Galvanized steel carries a zinc coating. Galvalume is steel coated with an aluminum-zinc alloy, which generally resists corrosion better in the same exposure. Painted sheets add a colour finish over the coating and cost more. The coating and the paint warranty are on the manufacturer sheet, and they are worth reading, because that is what decides how long the roof lasts.

Gauge is the steel thickness, and a lower number means thicker steel. A thinner gauge is cheaper and dents more easily, which matters under snow and hail. Pick it for the building, not the price.

Steel sheets cost more up front than asphalt shingles per square foot of roof, and last longer. For a cabin, a barn or a shed that is hard to reach, the lifespan can win. For a house in a city, shingles are more common. Run both through the same arithmetic, with the real roof area and the real accessories.

Many exposed-fastener metal panels call for a minimum roof slope, often 3 in 12 or more. Check the manufacturer rule before you buy, because a slope that is too shallow will leak.

The shelf prices on this page are what Quebec retailers charge. If you build somewhere else, the best official yardstick we have is Statistics Canada's building construction price index, which follows what builders pay for residential building as a whole in each province.

Quebec, where our shelf prices come from, reads 113.3, up 5.0% on a year earlier. Alberta is highest at 117.8 and Ontario lowest at 106.6 in the second quarter of 2026. These are cost indexes set to 100 in a base period: they say how fast residential building costs have moved in each province, not what a single item sells for at your local store. We will publish real shelf prices for your province as it goes live.
