Cossette Roofing installs elastomeric membranes (SBS modified bitumen) for residential and commercial flat roofs in Gatineau, Ottawa, and the Outaouais since 2005. Lifespan of 35 to 40 years. Weighs half as much as gravel covering. Can be installed over existing bitumen roofs. Torch-welded by certified technicians. RBQ License 5697-7788-01.
An elastomeric membrane is a roofing covering made from bitumen, polymers, and fiberglass or polyester. It is a premium option for flat roofs, offering superior energy efficiency compared to traditional gravel covering and a lifespan of 35 to 40 years.
Elastomeric membrane weighs approximately half as much as gravel covering, reducing structural stress. If the existing roof is bitumen, the new membrane can be installed directly on top, speeding up the project. Membranes are available in different colors; lighter colors reflect summer heat.
Installation is performed by torch welding or specialized adhesive by certified technicians. Cossette holds the required certifications and insurance. Contact 819-777-7177.
An elastomeric membrane is a flat roofing system made from SBS (Styrene-Butadiene-Styrene) modified bitumen reinforced with fiberglass or polyester. It is installed by torch-welding layers together, creating a waterproof, flexible covering that adapts to temperature changes. Cossette has installed elastomeric membranes since 2005.
A properly installed elastomeric membrane roof lasts 35 to 40 years. It weighs about half as much as traditional tar and gravel roofing and offers superior energy efficiency. Cossette’s certified technicians install membranes using torch-welding for maximum adhesion and waterproofing.
Elastomeric membrane (SBS modified bitumen) and TPO are both used for flat roofs, but they have different characteristics. Elastomeric membrane is torch-applied and self-healing, making it excellent for Quebec’s freeze-thaw cycles. TPO is heat-welded and reflective. Cossette installs both systems and recommends the best option based on your building, budget, and performance needs during the free evaluation.
Yes. If the existing roof is bitumen-based, a new elastomeric membrane can often be installed directly over the old surface, reducing labor time and waste. Cossette’s technicians inspect the existing roof condition to determine if an overlay is appropriate or if full removal is required.
Costs vary by roof size, access difficulty, number of penetrations (vents, skylights), and whether the existing roof needs removal. Elastomeric membrane is generally mid-range in price compared to other flat roof options. Cossette provides free on-site estimates. Call 819-777-7177.
Cossette both installs new elastomeric membrane systems and repairs existing ones. Repairs can include patching damaged sections, resealing seams, fixing flashing around penetrations, and addressing ponding water issues. Emergency repairs are available 24/7.
