Roofing in Sarnia

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.

Full replacements commonly require a building permit or regulatory compliance; small like-for-like repairs usually don't. Rules vary by country and municipality, and a legitimate contractor will know and handle the paperwork — treat 'we don't need a permit' on a full reroof as a flag to double-check.

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.

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.
