Elastomeric membrane roofs

Elastomeric membrane is durable, easy to maintain and has many other benefits, including ease of installation. This type of membrane is typically installed on flat roofs. Its resistance to harsh weather, humidity and extreme heat allows it to provide excellent waterproofing performance for many years. 

Conventional elastomeric membranes are installed using a torch that causes the different layers to fuse. Self-adhesive membranes are installed cold, eliminating fire hazards and unpleasant tar odours.

Whether you choose a conventional or self-adhesive elastomeric membrane, you will ensure your roof’s durability and longevity by working with the experts at Groupe Pentagone.

TPO – PVC membrane roofs

TPO (thermoplastic polyolefin) or PVC (polyvinyl chloride) roofs are made of environment-friendly, economical plastic membranes. Thanks to their unique composition, TPO and PVC membranes are highly resistant to damage caused by bacteria, ultraviolet light and exposure to the elements. They are ideal for coping with Quebec weather, moisture from snow and rain, and even harmful insects. A sustainable choice that’s less polluting than many other options on the market.

Asphalt-and-gravel membrane roofs

Asphalt-and-gravel roofing is ideal for flat and nearly flat, commercial roofs. This type of roofing is known for its durability and weather-resistance. It is made of multiple layers of roofing felt and liquid asphalt. A layer of gravel is laid on top of those materials, to protect the asphalt from UV light and the elements. This is a low-maintenance roofing type, because its composition makes it easy to repair localized damage at minimal cost over the roof’s lifespan.

EPDM membrane roofs

EPDM (ethylene propylene diene monomer) roofing is a synthetic rubber membrane. It is very resistant to deep winter cold and extreme summer heat. It is prized by construction professionals for its elasticity and flexibility, which minimize cracking over the years. EPDM roofs are also considered highly environment-friendly because of their longevity and recyclability. 

Green rooftops

In addition to adding value to your building, a green rooftop is an integral part of an environment-friendly, sustainable solution. When you opt for edible plants, your rooftop can become a source of food as well as a place to relax. Whether you grow food or ornamentals on your green rooftop, it will provide a natural boost to the building’s insulation and soundproofing while improving rainwater and snowmelt drainage. A green rooftop must be installed by professionals, to ensure that the condition of the existing roof and the building’s structure are properly assessed. Groupe Pentagone is up to the task.
