Roofing in Peterborough

Dry, settled weather — and before your region's storm or rainy season, not after it starts. Roofers book out weeks or months ahead of peak season, so schedule inspections early; shoulder-season slots are often cheaper and easier to get.

Sometimes — an overlay saves tear-off cost but hides deck problems, adds weight, and often shortens the new roof's life and warranty. Many codes and manufacturers limit roofs to two layers. Tear-off costs more upfront and is usually the better long-term decision; get both options priced.

Policies generally cover sudden storm damage (wind, hail, fallen trees) but not gradual wear and age. Document damage with dated photos immediately, get an independent assessment before signing anything a door-knocking contractor puts in front of you, and check whether your policy pays replacement cost or depreciated value on older roofs.

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.

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.

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.
