Roofing in Le Sud-Ouest

Missing, cracked or slipped tiles/shingles; granules collecting in gutters; daylight visible in the attic; damp patches or staining on top-floor ceilings; sagging roof lines; and moss holding moisture against the surface. Catching these early usually means a repair instead of a replacement.

Typically 10-30%, or enough to cover ordered materials, with the balance staged against progress and completion. Never pay in full upfront, and be wary of anyone who can start 'tomorrow' if you pay cash today — good roofers have lead times.

Tear-off and disposal, underlayment spec, flashing replacement (not reuse), ridge and valley details, a unit price for replacing rotten decking discovered mid-job, scaffolding or edge protection, and cleanup with a magnetic nail sweep. A quote missing the deck-repair unit price is the classic setup for large mid-job extras.

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.

Yes — replacing one slope or section is common after localised storm damage and costs far less than a full reroof. The trade-offs are colour mismatch with weathered existing material and tying new work into old underlayment. It makes most sense when the rest of the roof has meaningful life left.

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.
