RBQ : 5760-5842-01
Flat roofs at the eastern end of the Island of Montreal face some of the region's most demanding weather conditions—ranging from the proximity of the St. Lawrence and des Prairies rivers to freeze-thaw cycles that can compromise roofing membranes in just a few seasons. At ML Pro Toitures Inc., our team works directly with residential, commercial, and industrial property owners in Rivière-des-Prairies–Pointe-aux-Trembles who require a meticulous flat-roofing specialist; we handle all work in-house—without subcontractors—and provide a 10-year warranty on every project. Our RBQ license (5760-5842-01) and expertise with Soprema and IKO products ensure that every installation meets manufacturer standards.
Why do flat roofs in Rivière-des-Prairies–Pointe-aux-Trembles deteriorate faster near waterways?
Exposure to ambient moisture from both the main river and the Rivière des Prairies accelerates wear on waterproofing membranes, particularly at seams, flashings, and roof drains. A flat-roofing specialist in Rivière-des-Prairies–Pointe-aux-Trembles who understands these climatic realities can accurately assess whether a full replacement is necessary or if targeted repairs will suffice to extend your roof's service life. Our flat-roof maintenance service in Rivière-des-Prairies includes systematic inspections of drains, seams, and the overall condition of the membrane, enabling us to detect early signs of water infiltration before they escalate into costly damage. To learn more about our structured maintenance program, please visit our flat-roof maintenance page.
What is the difference between an elastomeric membrane, a TPO membrane, and an EPDM membrane?
Each type of membrane meets specific needs based on the building, its exposure to the elements, and the available budget. The torch-welded, two-ply elastomeric membrane offers proven resistance to the freeze-thaw cycles of the Quebec climate, while single-ply, lightweight TPO and EPDM membranes can be installed over existing roofs and are particularly well-suited for the borough's commercial and industrial buildings. To compare these options and select the right solution for your building, visit our page dedicated to flat roofing services in Montreal; there, we provide details on each flat roofing system we install in Rivière-des-Prairies–Pointe-aux-Trembles in accordance with manufacturer standards.

Here is a concrete overview of the work our team carries out for residential, commercial, and industrial property owners in the eastern part of the island, with the same level of rigor for every project.
Complete flat roof replacement: We remove the old membrane, inspect the insulation and decking, and then install a new waterproofing system in accordance with manufacturer standards.
Installation of a two-ply elastomeric membrane: The two layers are torch-welded to form a perfectly monolithic assembly, designed to withstand Quebec winters and the humidity fluctuations of waterfront areas.
Installation of TPO and EPDM membranes: These single-ply systems are particularly well-suited for commercial and industrial roofs and can be installed over existing roofing to minimize demolition costs.
Targeted repair and sealing: When a full refurbishment is not required, we precisely address vulnerable areas—such as detached seams, blisters, and cracks around drains or flashings.
