EVERYTHING THERE IS TO KNOW ABOUT ELASTOMERIC MEMBRANES

Do you have a building with a flat, low-pitched or terraced roof? Have you considered the possibility of opting for an elastomer membrane roof? At Couvreurs de l’Est, in Montreal, we particularly appreciate the advantages of this solution. Read on to learn more about it!


What is an elastomeric membrane?

An elastomeric membrane is made from modified bitumen which can be reminiscent of rubber. Modifiers are added to bitumen to give it strength and durability. A roof made with this membrane requires two layers, a so-called base membrane, then a finishing layer made up of fine gravel (this is what gives the roof its color).


What types of membranes are offered?

At Couvreurs de l’Est, we offer two types of elastomeric membranes. The first, traditional, involves a fusion of the two layers with a blowtorch. It is the most popular choice with architects. The second, called self-adhesive, is applied cold. Requiring a primer, it nevertheless limits the smell of hot asphalt and the risk of fire.


How long does it last?

If properly installed by a professional and well maintained, an elastomeric membrane can retain its effectiveness for up to 30 years.


What about its waterproofness?

Its robustness and double layer allow the elastomeric membrane to offer excellent impermeability, despite the rigors of the Quebec climate. Its degree of elasticity also makes it more resistant to hail and snow. If it has been installed correctly, the drain works well and it is inspected regularly, it will remain effective for a long time.


What maintenance is required?

An annual inspection and a few occasional small interventions are all that is needed to allow the membrane to maintain and even extend its life.


What are the conditions for its installation?

The elastomeric membrane can be installed almost at any time. The technique used necessarily involves the know-how of professionals. However, they can tackle the task as much on a hot summer day as on cooler fall days. However, cold weather is less advisable, since it requires additional heating of the product.
