What types of sheet metal roofing are used in Quebec?

Sheet metal roofing is very popular in Quebec for its durability and weather resistance:

Types of metal roofing:

• Corrugated (ribbed) sheet: Pre-painted galvanized steel panels with vertical ribs. The most economical. Minimum slope: 3:12 (14°). Lifespan: 30-50 years. Cost: $5 to $8/sq ft
• Standing seam: Panels with locked vertical joints, no exposed fasteners. Very watertight. Minimum slope: 1:12 (5°). Lifespan: 40-60 years. Cost: $8 to $14/sq ft
• Steel or aluminum shingles: Imitate the look of asphalt shingles but much more durable. Lifespan: 30-50 years. Cost: $7 to $12/sq ft
• Copper: Standing seam or batten seam. Lifespan: 100+ years. Cost: $15 to $25/sq ft

Advantages of metal roofing:

• Resists freeze/thaw cycles (does not crack like asphalt shingles)
• Sheds snow more easily (favorable slope)
• Reflects heat (reduces heat islands, cooling savings)
• 100% recyclable at end of life

Installation must comply with the Quebec Construction Code and the APCHQ Roofing Guide.
