Choosing Flat Roof Coverings in Montreal, Laval, and the South Shore
The city of Montreal is home to the highest concentration of flat roofs in Quebec, primarily on industrial, commercial, or residential buildings. The four main types of coverings used for flat roofs in Quebec are:
- Elastomeric Membrane
- Asphalt and Gravel Roof
- Vinyl Membrane
- Synthetic Rubber Membrane (EPDM)
The first two types are considered multi-layer, while the latter two are single-layer. Each type has its advantages and disadvantages, which we will explore below.
Elastomeric membrane is a popular choice for flat roofs in Quebec, with over 45 years of history. This covering is highly resistant to bad weather, temperature changes, snow, and strong winds. Experts agree that this type of roof has a lifespan of approximately 35 years with minimal maintenance, making it a cost-effective investment for flat roof building owners. Elastomeric membrane is very common in the cities of Laval, Montreal, and on the South Shore.
What is Elastomeric Membrane?
The elastomeric membrane is a petroleum-based material, similar to plastic, and strongly resembling rubber. Installation requires the application of two layers that fuse together using the heat of a torch. The first layer provides waterproofing, while the second, often covered with gravel or ceramic, gives the roof its color.
Elastomeric Membrane Repair
To maintain the effectiveness of your roofing, it is advisable to have an annual inspection performed by a professional. If repairs are necessary, a qualified roofer can intervene quickly to ensure the durability of your flat roof.
In the city of Laval, asphalt and gravel covering is a popular alternative for flat roofs. This type of roofing consists of 4 to 5 successive layers of felt and bitumen, with heated asphalt between each layer. This system is durable and highly resistant to temperature variations.
This covering can last between 20 to 25 years, and an annual inspection is necessary to check its waterproofing and add gravel if needed.
The TPO vinyl (Thermoplastic Polyolefin) is another single-layer covering option, less common but with many advantages. Its glossy surface offers an aesthetic appearance and ease of cleaning. Furthermore, TPO is effective against bacteria, mold, and pest insects. However, it is less resistant to tears and scratches, which requires careful installation to avoid damage.
The synthetic rubber (EPDM) covering is similar to TPO, but it stands out due to its installation via adhesive tape or an ultra-strong adhesive. This type of membrane is ideal for green roofs, offering high resistance to bacteria, tears, and mold.
Multi-Layer Roofing Systems
Multi-layer roofing systems, such as the elastomeric membrane and asphalt and gravel, offer a longer lifespan but are often more expensive to install. They are popular because they are effective and easy to install.
Single-Layer Roofing Systems
Single-layer membranes, such as TPO vinyl and EPDM, have the advantage of being recyclable and often less expensive. However, their lifespan is shorter, ranging from 15 to 35 years, which makes them more suitable for green or industrial roofs.

Roof Replacement
An endless cycle of repairs often signals a deeper problem. At some point, roof replacement costs less than a series of temporary fixes. The chosen material takes into account your building and Montreal's climate, with installation compliant with RBQ standards at every step.
Roof Repair
The freezing and thawing of the Quebec winter weaken Montreal roofs, often without being visible at first glance. Blisters, peeling, cracks around penetrations: our roofers trace back to the real cause rather than patching the symptom. The roof repair is then carried out with materials chosen to last over time.
Roof Inspection
Identifying a fragile area before it becomes a structural problem is the whole point of an annual roof inspection. Our roofers examine the membrane, flashings, drains, and junctions. You then receive a detailed report to prioritize work according to your budget.
