Roofing Services in Laval

Laval is the third-largest city in Quebec and one of the most active residential roofing markets in the Greater Montreal region. Its housing stock spans several decades and styles, from the post-war bungalows and split-levels of Chomedey and Laval-des-Rapides to the newer two-storey homes in Sainte-Dorothee and Fabreville. Each era of construction brought different roofing materials and methods, which means Laval properties present a wide range of roofing needs. Bungalows built in the 1960s and 1970s across neighborhoods like Chomedey, Vimont, and Pont-Viau often have low-slope or moderately pitched roofs that were originally covered with three-tab asphalt shingles. Many of these roofs have been re-shingled at least once, and some are now due for a complete tear-off down to the deck, allowing inspection of the sheathing for rot or damage before installing new underlayment and architectural shingles. We frequently discover ventilation deficiencies on these older homes that contribute to ice damming and premature shingle deterioration. Newer developments in Sainte-Dorothee, Duvernay, and Sainte-Rose feature homes with steeper roof pitches and more complex geometries, including multiple dormers, valleys, and architectural details that require precise flashing work. These roofs are typically covered with laminated architectural shingles rated for high wind resistance. The complexity of these roof lines means that proper installation around penetrations, valleys, and transitions is essential to prevent water infiltration. Laval sits on an island in the Riviere des Prairies and the Riviere des Mille Iles, which creates a microclimate that can produce slightly different weather patterns than downtown Montreal. Wind exposure is notable, particularly in neighborhoods along the waterfront and in open suburban areas. Roofing materials in Laval must be rated for the wind conditions common to the region, and fastening patterns need to meet or exceed manufacturer specifications for high-wind zones. Flat roofs are also common in Laval, particularly on commercial-residential mixed buildings along boulevards like Cure-Labelle, des Laurentides, and Saint-Martin. We install and repair elastomeric membrane, TPO, and modified bitumen systems on flat and low-slope structures throughout the city.
