RBQ : 5760-5842-01
As the owner of a duplex or triplex in LaSalle, you know that the flat roofs in this borough have endured decades of freeze-thaw cycles that eventually take their toll on aging membranes. ML Pro Toitures Inc.—an RBQ-licensed roofer (license 5760-5842-01)—handles your flat roofing project in LaSalle using the same team from start to finish, with no subcontracting. Every project is backed by our 10-year workmanship warranty, providing you with tangible protection long after the job is done.
Why are the flat roofs in LaSalle deteriorating faster than expected?
LaSalle features a high concentration of duplexes and triplexes built between the 1950s and 1980s, many of which have roofing membranes that have long since exceeded their useful lifespan. Montreal winters bring repeated freeze-thaw cycles that cause joints to crack, membrane flashings to lift, and flashing around drains to weaken. As flat-roofing specialists in LaSalle, we recommend an annual inspection to detect these issues early—before water infiltration compromises your building's structure—which is precisely what our flat-roof preventive maintenance program covers.
Do you need a permit to redo your flat roof in LaSalle?
In LaSalle, as in all Montreal boroughs, a municipal permit is required to replace flat roof surfacing, and certain areas are subject to additional standards regarding the building's architectural character. Hiring a flat-roof specialist in LaSalle who is familiar with the City of Montreal’s administrative processes helps avoid the delays and permit refusals that can stall a project. We guide our clients through these procedures and ensure all installations comply with municipal requirements; visit our page on flat-roof elastomer membrane installation to learn more about the materials we use.
Is your roofing work guaranteed, and for how long?
All our flat roofing work in LaSalle is backed by a 10-year workmanship warranty, in addition to the manufacturer warranties provided for the Soprema and IKO membranes we install according to manufacturer specifications. Working with an RBQ-licensed contractor also ensures that your project complies with current building codes and that your recourse in the event of an issue is clearly defined.
