Shingle Roof Cost in Montreal

The cost of a shingle roof replacement depends on several factors that are specific to each property. Roof size is the most obvious variable, measured in square feet of roof area rather than floor area, since roof pitch adds surface area beyond the footprint of the house. A steeper roof has more surface to cover than a flat or low-slope roof over the same floor plan. Roof complexity also affects pricing significantly. A simple gable roof with two planes and a single ridge is straightforward to shingle. A roof with multiple valleys, dormers, hips, skylights, chimneys, and wall-to-roof transitions requires more flashing work, more cutting, and more time. Each penetration and intersection is a potential leak point that must be properly detailed. Material choice plays a major role. Three-tab shingles are the most economical option but offer a shorter lifespan and lower wind resistance. Architectural laminated shingles are the current industry standard, providing better durability, wind ratings, and aesthetic depth. Premium designer shingles offer enhanced appearance and performance but at a higher cost per square. The condition of the existing roof deck affects cost as well. If the plywood or OSB sheathing is damaged, soft, or delaminated, it must be replaced before new shingles can be installed. This is only discoverable once the old roofing is removed, which is why reputable contractors include a provision for deck repairs in their estimates. Accessibility matters too. A single-storey bungalow with clear access around the perimeter is easier and safer to work on than a three-storey building in a dense urban area where equipment staging is constrained. Difficult access increases labor time and safety equipment requirements. [PRICING DATA TO BE RESEARCHED AND ADDED] Contact us for a free estimate tailored to your specific property.
