What Is Elastomeric Membrane and Why Is It Effective?

Elastomeric membrane is also known as bilayer membrane and, as the name suggests, it consists of two layers. The first layer is an elastomeric membrane made of SBS-modified bitumen (base layer), and the second is a finishing membrane also made of bitumen.

The base membrane is first adhered across the entire surface of your flat roof. Then, the top layer is unrolled while being heated with a torch so that it softens and fuses with the base membrane.

This torch-applied technique creates a thick, durable final membrane with maximum adhesion and waterproofing. Colored granules, most often white, are added to protect the roof from the sun’s heat.

Because a torch is used during the insertion process, an elastomeric membrane roof requires specific expert skills.

Many Advantages

An elastomeric membrane roof provides many benefits to residential and commercial owners. Indeed, it is no coincidence that, today, about 50 % of flat roofs, whether residential or commercial, is covered with elastomeric membrane.
An elastomeric membrane is aesthetic, durable, weather resistant, and easy to maintain. It is worth considering as an alternative roofing for your new residential or commercial property.
Thanks to its high waterproofing capacity, the elastomeric roofing membrane effectively protects homes and commercial buildings with flat or low-slope roofs. Its rubber-like texture and thickness make it resistant to harsh weather, extreme temperatures, and heat.
It also stands up to impact and UV damage. Plus, it's easy to repair when needed. An annual or biennial maintenance visit from our team will help extend the lifespan of your elastomeric roof.

We can perform any necessary repairs and reseal around rooftop equipment. If needed, we can also replace or install roof ventilators.
Another advantage: by choosing white granules to cover the surface of your elastomeric roof, you'll reduce heat buildup inside your building. Since white stays cooler than darker colors under the sun, your indoor space will be more comfortable and require less air conditioning.
You can even install a rooftop terrace to enjoy the warmer months! Condo buildings, restaurants, and nightclubs are already doing it — and residential property owners can also create a rooftop patio on their garage or flat-roofed home.
Although slightly more expensive per square foot than other types of membrane, elastomeric membrane is a wise investment since it has a longer life. Indeed, properly installed, it can be effective for more than 30 years.
