Dorval's post-war housing stock is full of flat-roof homes now pushing 40 to 60 years old, and many of those membranes are overdue for a professional eye. At ML Pro Toitures inc., we provide complete flat roof in Dorval services covering everything from annual preventive inspections and drain checks to full membrane replacement and emergency call-outs. We hold RBQ licence no. 5760-5842-01, back every job with a 10-year workmanship guarantee, and you deal with the same crew from the first visit to the final inspection.

Most flat roof membranes in Dorval benefit from a professional inspection at least once a year, ideally in spring after the freeze-thaw season has run its course. Our flat roof maintenance Dorval program targets the details that matter most: drain flow, joint integrity, membrane adhesion at edges and penetrations, and any cracking caused by thermal cycling near the airport corridor. Catching a minor joint failure in April costs a fraction of what a water infiltration into the structure will cost by September, and our preventive visits are designed precisely to find those problems early, before they become interior damage. Learn more about our scheduled flat roof maintenance services and how they can extend your membrane's lifespan.

The combination of lake-effect humidity from Lac Saint-Louis, hard winters, and intense summer UV exposure makes Dorval one of the more demanding environments for a flat roof in Dorval to perform reliably over time. Drain blockages, membrane blistering from thermal expansion, and joint separation at parapet walls are the failure points we encounter most often, and each has a targeted fix that stops the problem before it compounds. When you need a full picture of what your roof requires, our complete flat roof solutions for Quebec properties walks through every repair and replacement option we offer.

A sudden water infiltration after an ice storm or heavy rain cannot wait for a standard appointment, and we are available for emergency interventions on any flat roof in Dorval when rapid action is needed. Our team arrives with the materials and equipment to stabilize the roof, isolate the source of the leak, and apply a durable repair rather than a temporary patch. Dorval property owners dealing with urgent roof damage should explore our emergency roof repair service to understand how quickly we can mobilize and what the intervention process involves.

Every property is different, and our team brings the right solution to each job based on the roof's age, exposure, and existing condition. Here is what our Dorval clients can expect when they work with us.
Elastomeric membrane installation : We install Soprema and IKO bicouche systems in two torch-welded layers, providing a watertight seal engineered to withstand Quebec's full range of freeze-thaw cycles.
TPO and EPDM membrane options : For properties where heat-reflective or single-ply systems are a better fit, we supply and install TPO and EPDM membranes to manufacturer specifications.
Preventive maintenance visits : Our scheduled inspections cover drain flow, parapet wall joints, membrane adhesion, and penetration sealing, covering everything needed to extend the life of an existing roof before problems develop.
Emergency leak response : When a sudden infiltration threatens your interior, we respond promptly and carry the materials needed to isolate and permanently repair the source rather than apply a stopgap measure.
Foundation and concrete waterproofing : For Dorval homeowners managing both roof performance and basement moisture, we protect the full building envelope below grade using the same rigorous standards applied to every membrane installation above.

Dorval's airport corridor and lakeside exposure create a microclimate that accelerates membrane aging, and selecting the wrong system for that environment leads to premature failure regardless of installation quality. When a Dorval homeowner calls ML Pro Toitures inc., they reach the same crew that will show up on the roof: no subcontracting, no hand-offs, and full accountability under RBQ licence no. 5760-5842-01. For properties where elastomeric membrane is the right choice, learn more about our elastomeric membrane roofing installations and the standards we apply on every flat roof in Dorval project.
