Installed price before HST, scope and time on site for the three roof types. Every price is confirmed with a free written quote.

The calculator multiplies the area you enter by our installed rate for the service you pick, applies the shingle grade, adds the options you tick and rounds to the nearest $25. For a repair, pick the repair type instead of a size: leak and flashing repairs run $300 to $800, shingle patches $250 to $600 and flat roof patches $400 to $1,200.
Roof area is larger than the floor area of the house because of the pitch and the overhangs. If you are not sure of yours, use one of the presets (bungalow, two-storey, large home or garage) and we measure the roof at the free inspection. For prices by house size and what moves the number, see our roof replacement cost guide.
