Roofing in Villeray–Saint-Michel–Parc-Extension

A straightforward single-family roof takes 1-3 days for asphalt shingles or metal sheeting, and up to 1-2 weeks for tile, slate or complex multi-plane roofs. Weather delays are normal — a competent crew will never strip more roof than they can waterproof the same day.

Typical service lives: asphalt shingles 15-30 years, concrete tile 40-60, clay tile and slate 60-100+, metal 40-70, flat membranes (felt, EPDM, TPO) 15-30. Underlayment and flashings usually fail before the covering itself, which is why old roofs leak even with intact tiles.

Repair when damage is localised — a few slipped tiles, one flashing leak — and the roof is under about two-thirds of its expected life. Replace when leaks recur in different places, more than roughly 30% of the covering is failing, or repair quotes start approaching a third of replacement cost. A good roofer will show you photos from the roof to justify either answer.

It scales with roof area, pitch, number of storeys, access, and material. Basic asphalt shingle or concrete tile sits at the bottom of the range; metal, slate and clay cost two to four times more. Tear-off of the old covering, disposal, scaffolding or edge protection, and hidden deck repairs are the lines that move a quote most — make sure all four are priced before comparing.

A typical asphalt shingle replacement runs CAD $8,000-$25,000 with most homes landing around $12,000-$15,000; metal roofs run $18,000-$50,000. Per-square-foot pricing of $5-$13 installed is typical for asphalt.

It's possible but not ideal — shingle adhesive strips need warmth to seal, and snow slows and endangers crews. Most contractors work April-November; winter work is usually limited to emergency repairs and ice-dam mitigation.
