    The various materials for use on flat roofs

    As flat roof specialists, we recommend the use of an elastomeric membrane or thermoplastic polyolefin (TPO).

    TPO flat roofs

    With a useful life ranging from 20 to 30 years, TPO flat roofs can withstand extreme weather, bacteria and UV radiation. TPO membranes are also effective at resisting insects and moisture and they require no maintenance. What’s more, they’re sturdy and easy to install.

    A TPO membrane is composed of a single layer of thermoplastic polyolefin approximately 1.5 cm thick. As a result, it combines durability and performance. White TPO membrane is the most popular type, as it reflects the rays of the sun rather than absorbing heat. The temperature of the roof remains cooler in the summer, which helps reduce the cost of air conditioning. The white membrane also reduces heat islands, especially in urban environments.

    Elastomeric membrane flat roofs

    Elastomeric membranes have been available on the market for more than 40 years. For a number of years, this has been the most popular material for flat roof construction and repairs in Laval and the Greater Montreal area. It’s frequently used to replace asphalt and gravel roofs. The characteristics of elastomeric membrane roofing are very similar to those of TPO.

    The elastomer comes in the form of an extremely durable two-layer membrane. During installation, the two layers are fused with the aid of a blowtorch. However, this process increases the risk of fire. That’s why it’s recommended to have it installed by qualified professionals with the necessary equipment and experience. At Couvreur Couv-Toit, we have the required certifications and licenses to ensure that we perform all of our installations in accordance with the very highest standards.

    Rooftop snow removal

    As a result of numerous winter storms, snow and ice accumulate on your roof, representing a danger not only to people passing nearby but also to the structure of your building. In fact, the weight of the snow can weaken your roof to the point where it collapses. To limit the risks of damage and injury, it’s recommended to have the snow removed from your flat roof by professionals.

    At Couvreur Couv-Toit, our experienced team of snow removal experts is properly equipped to remove the excess weight from the structure safely and securely.

    • I’m very satisfied with the work that was done. The team was super-professional and gave me great advice. I strongly recommend them.

    • Outstanding service from the moment I got the estimate until the work was done. Out of the five companies I called, this was the only one where the appraiser actually went up on the roof. The team of eight (!!!) was punctual, the work was well done, and they cleaned up everything before they left.

    • I was fully satisfied with the repair work done on my TPO membrane roof. The team that came to my home was energetic, upbeat and conscientious. I spent the whole day on the roof with them, and I truly felt that each and every one of them was firmly committed to doing the best job possible. What’s more, when I came down at the end of the day, to my surprise, the house, the property, the street and everything around them had been thoroughly cleaned, as if nothing had happened. (For those who’ve pulled up an asphalt and gravel roof before, you know how hard it is to keep everything clean.) The team was well equipped, and the work was done quickly and with a good attitude (despite the cold a few days before Christmas of 2020). Three days later, the metalworkers came by to finish up everything, and I’m convinced that my roof won’t need any touch-ups for at least 30 years.
