Roofing Services in Montreal

Montreal is a city defined by its rooftops. From the iconic flat roofs of Plateau duplexes and triplexes to the pitched shingle roofs of suburban bungalows in Saint-Laurent and Ahuntsic-Cartierville, the island presents a remarkable diversity of roofing challenges. Each borough has its own dominant housing stock, and each housing type demands specific roofing expertise. The Plateau Mont-Royal, Rosemont-La Petite-Patrie, and Villeray-Saint-Michel-Parc-Extension are home to thousands of two- and three-storey walk-ups with flat or low-slope roofs. These buildings typically use elastomeric membrane, modified bitumen, or TPO roofing systems. The challenge with these roofs is drainage: flat roofs must be properly sloped toward drains, and ponding water is one of the most common causes of premature membrane failure. We inspect and correct drainage paths on every flat roof project we undertake in these neighborhoods. In residential areas like Notre-Dame-de-Grace, Lachine, and Riviere-des-Prairies, pitched roofs with asphalt shingles are the standard. These homes face the full force of Quebec winters, with heavy snow loads, ice dam formation along eaves, and the relentless freeze-thaw cycling that can lift shingles and compromise flashing over time. Proper attic ventilation and insulation are critical to preventing ice dams, and we assess these factors as part of every shingle roof inspection. Montreal sits in a climate zone where roofs must withstand temperature swings that can exceed 60 degrees Celsius across the year. Summer heat bakes roofing materials, while winter cold contracts them. Wind-driven rain in spring and fall finds every gap in flashing and sealant. These conditions make material selection and installation quality absolutely critical. A roof that performs well in a milder climate may fail prematurely here. We serve homeowners and property managers across every Montreal borough. Whether your building needs a full membrane replacement on a flat roof in the Plateau, emergency leak repair after a winter storm in Verdun, or a complete shingle tear-off and reinstallation in Anjou, our team has the experience and equipment to handle the project. We also work with multi-unit property owners who need coordinated roofing programs across several buildings. Every Montreal roofing project starts with a thorough inspection and a detailed estimate delivered by phone or video. We explain what needs to be done, why it matters, and what your options are, so you can make an informed decision about your roof.
