Elastomeric Membrane Laval
Elastomeric membrane has been the flat roof standard in Quebec for decades, and there’s a reason it’s still widely installed on residential and commercial buildings across Laval. It’s a system that was developed with this climate in mind: flexible enough to handle freeze-thaw movement, waterproof enough to deal with spring melt and heavy rain, and durable enough to last 20-plus years when properly installed and maintained.
XR TECH Roofing has installed and repaired elastomeric roofs across Laval and the Greater Montreal area for over 20 years. We’re RBQ licensed (# 5848-4080-01) and work on flat and low-slope roofs on everything from single-family homes to larger commercial buildings.
What Elastomeric Membrane Is
Elastomeric membrane, also called modified bitumen or simply elastomere in Quebec, is a reinforced asphalt-based roofing material that stretches and recovers without cracking. That flexibility is what makes it so effective here. As temperatures swing between -30C in January and 30C in July, a rigid membrane would crack at seams and flashings. Elastomeric membrane moves with the structure instead of fighting it.
It’s typically installed in two layers: a base sheet bonded to the roof deck, and a surface cap sheet applied by torch or cold adhesive. Torch-applied systems are the most common in Laval because they create a fully bonded, waterproof membrane without relying on mechanical fasteners that can back out over time.
Why It’s Still the Default on Laval Residential Roofs
For the type of housing stock common in Laval, including duplexes, triplexes, bungalows with flat or low-slope roofs, and older commercial buildings, elastomeric membrane is often the most practical choice. Replacement sheets are easy to source, skilled installers are plentiful locally, and the system has a long track record of performance through Quebec winters.
Our elastomeric membrane installations come with 25-year material warranties. The quality of the installation matters as much as the quality of the membrane itself, and we take the time to properly prepare the roof deck, address existing damage, and ensure drainage is working correctly before the new membrane goes down.

Winter Performance in Laval
Laval gets the full Quebec winter experience: significant snowfall, ice accumulation at roof edges and drains, and freeze-thaw cycles that put stress on any roofing system. Elastomeric membrane handles all of this well when it’s installed correctly.
The critical details are the perimeter flashings, the sealing around roof penetrations like HVAC units, vents, and skylights, and proper drainage slope so water doesn’t pond on the membrane surface. We’ve handled enough Laval roofs to know where these systems fail prematurely and how to avoid those failure points from the start.
Maintenance and Repairs
Even a quality elastomeric roof needs attention over time. Flashings can lift, small cracks can develop around penetrations, and granule loss on the cap sheet eventually exposes the membrane to UV degradation. Catching these issues early through regular inspection is almost always cheaper than dealing with water infiltration that has worked its way into the roof deck or insulation.
We handle roof repairs in Laval on elastomeric systems of all ages, from targeted patch repairs to full flashing replacements. If you’re unsure what condition your roof is in, a professional roof inspection gives you an honest assessment before any problems become expensive.
Replacement vs Repair: How to Know
An elastomeric roof under 15 years old showing localized damage is usually worth repairing. Once the membrane starts showing widespread alligatoring, significant granule loss, or repeated leaks that have been patched multiple times in the same area, replacement is almost always the better investment.
We’ll give you an honest assessment. If your roof has serviceable life left, we’ll tell you. If replacement makes more economic sense, we’ll explain why and give you a clear quote with no pressure.
