Elastomeric Membrane for Flat Roofs on the West Island

Elastomeric membrane is an excellent choice and is in fact recognized as the best covering for a flat roof. At Couvreur Sipa 2002, we are your flat roof experts.


In Quebec, the most used material for residential, commercial, and industrial roofs, flat roofs with very little difference in level, is elastomeric bitumen membrane (roof covered with an elastomeric membrane) laid in two thicknesses. These membranes were developed to reduce the need for maintenance and ensure a better seal. They also protect your roof from the sun, prolonging its durability. In Montreal, several boroughs require the installation of white roofs to counter the effects of urban heat islands. White elastomeric membrane is perfectly suited for this requirement.

The cost of a roof covered with an elastomeric membrane is about 10% more expensive than an asphalt and gravel covering. But given its much longer life, the elastomeric membrane is a better investment.

The Benefits of a Roof Covered with Elastomeric Membrane

  • Life span of 15 to 25 years - specialists even agree that a membrane properly installed by a professional roofer on a well-ventilated roof can last up to 30 years!
  • It can be installed regardless of the outside temperature
  • It is very weather resistant
  • It requires very little maintenance
  • It is waterproof and durable
  • It comes with a manufacturer’s warranty varying from 5 to 20 years

Technical Features

A roof covered with an elastomeric membrane is composed of a base membrane and a finishing membrane heated by torch to meld them together. The top membrane is coated with ceramic granules that give it its color (brown, gray black, red, green or white) and protect it from sunlight.


There is a real risk of fire during the hours following the installation of an elastomeric membrane roof.


It is therefore essential that the membrane be installed by a recognized elastomeric membrane roofer in the West Island of Montreal and surrounding areas. Couvreur Sipa 2002 holds liability insurance for possible accidents or unforeseen circumstances as a security measure, and we are recognized by SOPREMA Inc. as a qualified contractor for the application of their membranes, demonstrating our ability to deliver your elastomeric membrane roof in the best conditions!
