Your Trusted Flat Roof Contractor on Montreal’s South Shore
At Les Toitures E. Bourgeois, flat roofs have been at the heart of our expertise for many years.
We have completed hundreds of flat roof installation, repair, and inspection projects throughout Montreal’s South Shore, for single-family homes, multi-unit dwellings, warehouses, and commercial buildings of all sizes.
A poorly designed, improperly installed, or poorly maintained flat roof is a never-ending source of problems: persistent leaks, standing water, peeling roofing material, and water seepage into the structure. Our approach is to address the root causes of problems, not to temporarily mask them. We begin by conducting a thorough inspection before any work is done to provide you with the solution best suited to your building and your budget.
Service area: Boucherville, Longueuil, Brossard, Saint-Bruno-de-Montarville, Varennes, Sainte-Julie, Saint-Lambert, Chambly, Beloeil, Mont-Saint-Hilaire, Candiac, La Prairie, and the entire South Shore of Montreal.

Flat roof installation on the South Shore of Montreal
Are you building a new home, adding an extension, a garage, or a commercial building on the South Shore?
Les Toitures E. Bourgeois handles the complete installation of your flat roof, from design to delivery. We advise you on the choice of suitable covering for your building, whether SBS elastomeric membrane, TPO, or asphalt-gravel, as well as on the minimum slope, drainage system, and insulation thickness required.
A well-executed flat roof installation relies on several critical elements that our team masters perfectly:
- Design of the drainage slope towards the drains (minimum 2%, ideally 2.5%)
- Selection and installation of rigid insulation adapted to the building’s loads and use
- Installation of the covering according to manufacturer standards and the Quebec Building Code
- Careful treatment of all details: flashings, connections, chimneys, vents, and drains
- Safe installation according to CNESST requirements
Indicative rates for new flat roof installation on the South Shore:
- New residential flat roof (house or extension): $8 to $15 per square foot
- Garage or shelter with flat roof: $3,500 to $7,000
- Commercial building (depending on area): Personalized estimate
The final price varies depending on the area, the type of covering chosen, the insulation thickness, the complexity of the drains, and the presence of penetrations (chimneys, vents, skylights). Free and detailed estimate before any work.

Complete flat roof re-roofing on the South Shore of Montreal
When your flat roof covering has reached the end of its useful life or the damage is too extensive to be cost-effectively repaired, a complete re-roofing is necessary. This type of project involves completely removing the old covering down to the decking, inspecting and repairing the structure if necessary, and then installing a new complete system.

- Residential house flat roof re-roofing: $5,000 to $18,000
- Garage or extension flat roof re-roofing: $3,000 to $8,000
- Commercial re-roofing (per square foot): Personalized estimate
Several factors influence the price of a flat roof re-roofing: the area, the condition of the existing decking and insulation, the type of covering chosen, the number of penetrations, and the complexity of the drainage. Our estimate is always detailed item by item, with no hidden fees.

How much does it cost to re-roof a flat roof on the South Shore?
The cost of a flat roof re-roofing generally ranges from $5,000 to $18,000 for a residential house, depending on the area, the condition of the decking, and the chosen covering. The installation of a new flat roof is between $8 and $15 per square foot. A free and precise estimate is offered at (514) 559-1844.
What is the lifespan of a flat roof in Quebec?
The lifespan of a flat roof depends on the covering used. A well-installed two-ply SBS elastomeric membrane lasts 25 to 30 years with proper maintenance. Asphalt and gravel lasts 12 to 15 years. A TPO membrane can last 20 to 25 years. Adhering to maintenance intervals plays a decisive role in longevity.
Do you offer emergency service for flat roof leaks?
Yes, Les Toitures E. Bourgeois offers a 24/7 flat roof emergency service, available throughout the South Shore of Montreal. In case of an active leak or storm damage, call (514) 559-1844 immediately.
How often should a flat roof be inspected?
We recommend a professional flat roof inspection at least once a year, ideally in the spring after the snow melts. An inspection is also advised after every major storm, as well as before or after buying a property. This inspection helps detect problems early and intervene before they become costly.
Can a flat roof be repaired without being completely replaced?
Yes, if the damage is localized (crack, blister, detachment over a small area), a targeted repair is often sufficient and much less costly. Our expert determines during the inspection whether a partial repair is viable or if a complete re-roofing is necessary to ensure long-term waterproofing.
What is the minimum slope required for a flat roof?
Despite its name, a flat roof should never be completely horizontal. The Quebec Building Code requires a minimum slope of 2% towards the drains to ensure adequate water drainage. Insufficient slope leads to stagnant water accumulation, which accelerates the degradation of the covering and can cause structural overload.
What covering do you recommend for a flat roof on the South Shore?
For the climate of the South Shore of Montreal, we primarily recommend the two-ply SBS elastomeric membrane, known for its exceptional resistance to freeze-thaw cycles and wide temperature variations. For large commercial areas, a TPO membrane can also be considered. Consult our dedicated page on elastomeric membrane for more information.
Do you offer a warranty on your flat roof work?
Yes, all our flat roof interventions are covered by a written labor warranty. The installed coverings also benefit from manufacturer warranties, which vary depending on the chosen product. This double protection offers you peace of mind regarding the durability of your flat roof.
Do you serve the entire South Shore for flat roof work?
Yes, Les Toitures E. Bourgeois intervenes throughout the South Shore of Montreal for all your flat roof projects: Boucherville, Longueuil, Brossard, Saint-Bruno-de-Montarville, Varennes, Sainte-Julie, Saint-Lambert, Chambly, Beloeil, Mont-Saint-Hilaire, Candiac, La Prairie, and all surrounding municipalities. Call (514) 559-1844.
Do you also install skylights on flat roofs?
Yes, we also perform the installation and replacement of skylights on flat roofs. This intervention requires perfect integration into the covering to prevent any infiltration. Our roofers master this technique and guarantee total waterproofing around each installed skylight.
