What is SBS elastomeric membrane?
SBS (styrene-butadiene-styrene) elastomeric membrane is a polymer-modified bituminous roofing coating. It is specifically designed for flat or very low-slope roofs where asphalt shingles cannot be used due to the risk of water infiltration.
Its unique composition gives it remarkable mechanical properties: it deforms under stress without cracking, resists thermal shocks caused by Quebec’s freeze-thaw cycles, and returns to its original shape after a mechanical impact. It is this elasticity—hence its name—that makes it the most suitable roofing material for the harsh climate of Montreal’s South Shore.
Dual-layer elastomeric membrane is the industry standard in Quebec: a base layer (tie layer) is applied first, followed by a granulated surface layer that protects against UV rays and ensures final waterproofing. Together, they form a perfectly welded system, with no weak joints or points of vulnerability.

The advantages of elastomeric membrane for your flat roof
Exceptional durability and longevity
A well-installed and properly maintained dual-layer SBS elastomeric membrane can protect your flat roof for 25 to 30 years.
It is one of the best durability-to-cost ratios available on the market for flat roofs in Quebec, far ahead of asphalt and gravel (12 to 15 years) and comparable to TPO in terms of longevity.
Estimated lifespan (SBS dual-layer): 25 to 30 years with proper maintenance
Asphalt and gravel lifespan: 12 to 15 years
TPO membrane lifespan: 20 to 25 years
Superior resistance to the Quebec climate
Quebec is one of the most demanding environments for roofing: up to 100 freeze-thaw cycles per season, temperatures ranging from -30°C in winter to +35°C in summer, significant snow accumulation, and freezing rain. SBS elastomeric membrane is formulated specifically to withstand these extreme conditions without losing its waterproofing properties or cracking under thermal shock.
Installation possible in all seasons
Unlike asphalt shingles, which cannot be laid in very cold weather, elastomeric membrane can be installed year-round, including in winter. Both hot application techniques (torch-on) and cold application (self-adhesive) allow for installation in varied climatic conditions, which is particularly useful during winter emergencies on the South Shore.
Flawless waterproofing
The dual-layer system of the elastomeric membrane creates a continuous barrier without weak joints across the entire roof surface. Unlike single-pass systems, the two layers fused with a torch or bonded with self-adhesive offer redundancy that virtually eliminates any risk of infiltration if the installation is carried out according to industry standards.
Ease of repair
In the event of localized damage (blistering, cracking, peeling), elastomeric membrane is one of the easiest materials to repair. A damaged section can be resealed or replaced locally without having to redo the entire roof, which significantly reduces long-term maintenance costs.
Available in several colors and finishes
Elastomeric membrane is available in black (standard), white (white roof reflecting UV rays), gray, green, and other shades. White roofing is increasingly popular and sometimes required by certain municipalities due to its beneficial effect on urban heat islands.

Hot application or cold application: which method to choose?
Elastomeric membrane can be installed using two main techniques. The choice between the two depends on the type of building, the installation environment, and the manufacturer’s specifications.
Hot Application: Torch-on (traditional method)
Hot application is the most common method in Quebec. The roofer uses a propane torch to heat the underside of the membrane and the roof surface, creating a direct fusion between the two.
This technique offers maximum adhesion and a perfectly uniform weld.
Exceptional adhesion: complete membrane/substrate fusion
Optimal waterproofing at joints and connections
Ideal for complete refurbishments and new installations
Requires a certified roofer for safe torch handling
Slightly more expensive but offers the best durability
Cold Application: Self-adhesive membrane (flame-free method)
Cold application uses membranes with an adhesive side protected by a release film. The roofer removes the film and applies the membrane directly to the prepared substrate.
This method eliminates the use of a torch, making it ideal for certain specific situations.
- No fire risk, recommended for schools, hospitals, and sensitive buildings
- Installation possible at temperatures as low as -10°C
- Faster and quieter process
- Ideal for repairs and restricted access areas
- Slightly less adhesive than hot application over the long term
In most cases, Les Toitures E. Bourgeois recommends hot application for complete refurbishments on the South Shore, due to its superior adhesion and increased resistance to the rigors of the Quebec climate.
Cold application is preferred for targeted repairs and situations where the presence of a flame is not desired.

White elastomeric membrane (reflective white roof)
White elastomeric membrane is increasingly popular on the South Shore, particularly for commercial and institutional buildings. By reflecting the sun’s rays rather than absorbing them, it reduces heat buildup inside the building in summer, thereby lowering air conditioning costs. Some South Shore municipalities now encourage or require this type of membrane for new commercial constructions.

What is the price of an elastomeric membrane on Montreal's South Shore?
The cost of installing a dual-layer SBS elastomeric membrane is generally between $8 and $15 per square foot for residential, and between $7 and $13 per square foot for large-scale commercial. For a residential house, the total budget varies from $3,000 to $15,000 depending on the area and the condition of the decking. Get a free estimate at (514) 559-1844.
What is the lifespan of an elastomeric membrane?
A properly installed dual-layer SBS elastomeric membrane lasts 25 to 30 years with proper annual maintenance. Lifespan depends on the quality of materials, the precision of the installation, building ventilation, and the frequency of inspections and small repairs carried out over the years.
What is the difference between hot application and cold application?
Hot application uses a propane torch to fuse the membrane to the substrate, offering maximum adhesion and superior durability. It is the standard method recommended for complete refurbishments. Cold application (self-adhesive) does not use a flame, making it ideal for targeted repairs, sensitive buildings (schools, hospitals), and conditions where torch use is not possible.
Can elastomeric membrane be installed in winter on the South Shore?
Yes, this is one of the great advantages of elastomeric membrane. Hot application can be performed in cold weather, and cold application is possible down to -10°C. This flexibility allows for emergency interventions in any season on the South Shore, unlike asphalt shingles which cannot be laid in extreme cold.
What is the difference between SBS elastomeric membrane and TPO?
SBS elastomeric membrane is composed of modified bitumen and installed in two layers by torching or self-adhesion. It offers excellent resistance to frost and Quebec’s thermal cycles. TPO is a thermoplastic membrane heat-welded with hot air in a single layer, more reflective and ideal for large commercial roofs seeking to reduce heat islands. Both are durable solutions.
Can an elastomeric membrane be repaired without replacing it entirely?
Yes, if the damage is localized (blister, crack, peeling in a small area), a targeted repair is often sufficient and much less expensive than a complete refurbishment. Our expert determines during the inspection if a partial repair is viable or if a complete refurbishment is necessary to guarantee long-term waterproofing.
How often should an elastomeric membrane be maintained?
We recommend an inspection of your elastomeric membrane twice a year: in the spring after the snow melts, to identify damage caused by winter, and in the fall, to prepare the membrane before the first frosts. Cleaning the drains at each inspection is also recommended to avoid stagnant water accumulation.
Do you serve the entire South Shore for elastomeric membrane?
Yes, Les Toitures E. Bourgeois operates throughout Montreal’s South Shore: Boucherville, Longueuil, Brossard, Saint-Bruno-de-Montarville, Varennes, Sainte-Julie, Saint-Lambert, Chambly, Beloeil, Mont-Saint-Hilaire, Candiac, La Prairie, and all surrounding municipalities.
