West Island winters push flat roofs to their limits, with heavy snow loads, freeze-thaw cycles, and ice damming that quietly work their way into weak seams and flashing. We built our reputation as the Rive-Sud and Greater Montreal flat-roof specialist by treating every flat roof in Dollard-des-Ormeaux as a system that needs to resist wind, moisture, and temperature swings all at once. At ML Pro Toitures inc., our crews install elastomeric membrane, TPO, and EPDM systems backed by a 10-year warranty, so your roof stays sealed long after the first winter storm passes.

Ice damming forms when heat escaping through an attic melts snow on the upper sections of a roof, sending meltwater down to refreeze along a colder edge or parapet where it has nowhere to drain. Wind gusts off the lake add another layer of stress, lifting loose flashing and accelerating wear on seams built for milder conditions than a Quebec winter delivers. Effective ice dam prevention flat roof planning starts with proper drainage and a membrane that stays flexible through freeze-thaw cycles, which is why an aging flat roof in Dollard-des-Ormeaux often benefits from the same techniques we use for our elastomeric membrane installations in nearby Pointe-Claire.

Many established homes and duplexes in Dollard-des-Ormeaux carry a flat-roof addition over a sunroom, garage, or rear extension, and these lower sections often take on more standing water than the main sloped roof. Our approach to residential flat roofing West Island properties focuses on double-layer, torch-welded elastomeric membrane, TPO, and EPDM systems matched to the drainage pattern of each addition. When your flat roof in Dollard-des-Ormeaux needs a closer look before the next freeze-thaw season, our flat roof contractor services in Dollard-des-Ormeaux cover everything from inspection to full reconstruction.

A storm that tears back flashing or a sudden thaw that overwhelms a clogged drain does not wait for business hours, which is why our crews answer calls 24 hours a day, 7 days a week across the West Island. We show up ready to stop the leak first and diagnose the underlying cause second, since a rushed patch on a damaged flat roof in Dollard-des-Ormeaux tends to fail again within a season. If you need flat roof repair in Dollard-des-Ormeaux handled quickly and correctly, our 24/7 emergency roof repair service is staffed by the same roofing professionals who handle every project without subcontracting.

A well-maintained flat roof depends on more than a single service call. Here is what our crews bring to every project across the West Island.
Elastomeric membrane installation : We install double-layer, torch-welded elastomeric membrane systems designed to stay flexible through Quebec's freeze-thaw cycles.
TPO and EPDM options : For clients seeking a lighter or pale-coloured membrane, we also install TPO and EPDM systems that meet heat island reduction guidelines where required.
Foundation waterproofing : Beyond the roof deck, we seal foundations and basements to keep meltwater and groundwater from finding a way inside.
Seasonal maintenance visits : We recommend two inspections per year, one in spring to catch winter damage and one in fall to prepare the membrane for cold weather.
Roof snow removal : When snow loads climb past what a flat roof deck can safely carry, our crews clear it before it becomes a structural risk.
