What Affects Roof Replacement Cost in Whitby?
Roof size and pitch
Labour is quoted per square (100 sqft). Steep pitches require safety equipment and take longer, adding 15–30% to labour costs.
Material choice
3-tab asphalt shingles are cheapest ($80–$120/square material). Architectural shingles ($120–$180/square) are standard today. Metal roofing ($350–$600/square) lasts longest.
Number of layers to remove
If there are two or more layers of existing shingles, they must all be torn off before new installation. Each layer removal adds $800–$2,000.
Flashing and ventilation
Replacing chimney flashing ($400–$900), ridge vents, and soffit vents during a re-roof saves money versus doing it separately later.
