Elastomeric Membrane

An Elastomeric Membrane Roof : The Leading Choice in Canada

Elastomeric membrane roofs are very popular in Montreal and the surrounding areas – and rightly so! This type of modified-bitumen roof covering has proven its worth from one end of the country to the other. More than half of all flat, low-slope and terraced roofs in Canada are built using elastomeric membranes. This roofing material, which comprises two layers (base membrane and finishing membrane with coloured granules), boasts a number of features.

The Advantages of Elastomeric Membranes

Building owners and construction contractors choose elastomeric membranes for many different reasons :

  • Lifespan : A properly installed and well-maintained elastomeric membrane can last between 20 and 30 years;

  • Resistance : This material is ideally suited to the harsh Quebec climate;

  • Watertightness : The double layer ensures superior waterproofing;

  • Maintenance : A yearly inspection and minimal repairs are enough to extend its lifespan.

Elastomeric membranes offer another interesting advantage : they can be installed in almost any weather!

Two Types of Elastomeric Roofing

Couvreurs de l’Est offers two types of elastomeric membranes :

  • Traditional elastomeric membranes : Both flexible and strong, the traditional elastomeric membrane is fused to a finishing membrane using a blowtorch. This is the preferred type of membrane among architects;

  • Self-adhesive elastomeric membrane (cold installation) : The advantage of this type of product is that it does not require the use of a blowtorch, which reduces the risk of fire during installation. This cold-install technology also eliminates the odour of hot asphalt.

Why Choose an Elastomeric Membrane Instead of an Asphalt and Gravel Roof?

Asphalt and gravel roofs are still a good roof covering choice for flat roofs because of their amazing quality/price ratio. However, it may be advantageous to choose an elastomeric membrane if you want an attractive and uniform roof that will last much longer than an asphalt and gravel roof, with less maintenance.

Are Elastomeric Membrane Roofs Recommended for Projects in Montreal and the Surrounding Areas?

Absolutely! It is best to choose a pale-coloured finishing membrane in order to combat urban heat islands, and at the same time, extend the lifespan of your roof.
