Roofing Materials: Systems Used
Do you have a project we can help you with?
Elastomeric membrane
There are several elastomeric roofing systems for different types of use. Elastomeric roofs are often used on buildings with flat or low-slope roofs, such as multi-unit buildings, condominiums, and institutional buildings. Specifically, the elastomeric membrane is a two-layer system consisting of a base membrane and a finish membrane with colored granules on the surface. It is also used in inverted roofing systems. For more information, contact one of our specialists.
* Request your membrane sample from your representative.
Components
- Modified polymer bituminous waterproofing system
- Available in various colors : black, white, blue, green, red, gray
Benefits
- Superior sealing properties and resistance
- Elastic and flexible
- Highly adherent
- Protects the roof from premature degradation caused by weather conditions.
Longevity
- 25 years, more or less, depending on maintenance, weather, and activity on the roof.
Maintenance
- Little maintenance is required, but a visual inspection every spring and fall is recommended.
Multi-Ply Asphalt & Gravel
The multi-ply roofing systems are comprised of liquid asphalt and gravel. This is an economical and affordable solution, widely used in flat or low-slope roofs.
* Request your membrane sample from your representative.
Components
- Multi-ply waterproofing system made of liquid asphalt and gravel
- Available in gray and black
Benefits
- Superior resistance to asphalt softening and degradation caused by sunlight
- Top membrane is protected by gravel
- UV-resistant
Longevity
- 20 years, more or less, depending on maintenance, weather, and activity on the roof.
Maintenance
- Requires strict drains maintenance and debris removal, as well as continuous adding of gravel to protect the membrane. This should be done by a specialist.
Monolithic Membrane
Monolithic membrane solutions are often preferred for their waterproofing capacities in applications involving concrete, like parking lots, terraces, and roofs or inverted roofs.
* Request your membrane sample from your representative.
Components
- Monolithic rubberized asphalt membrane waterproofing system
- Available in black
Benefits
- Waterproof
- Flexible
- Seamless
Longevity
- 25 years, more or less, depending on maintenance, weather, and activity on the roof.
Maintenance
- Requires mainly drains maintenance. This should be done by a specialist.
EPDM Membrane
EPDM roofs are environmentally-friendly solutions suitable for large-scale, flat roofing.
* Request your membrane sample from your representative.
Components
- Ethylene/propylene/diene/monomer single-ply waterproofing system
- Available in black or white
Benefits
- Flexible
- Recylable
- Environmentally-friendly
Longevity
- 25 years, more or less, depending on maintenance, weather, and activity on the roof.
Maintenance
- Little maintenance is required, but a visual inspection every spring and fall is recommended.
TPO membrane
TPO roofs are often used for large surface flat roofs.
* Request your membrane sample from your representative.
Components
- Thermoplastic polyofelin single-ply waterproofing system
- Available in various colors such as gray, white and beige
Benefits
- Helps reduce heat islands
- Energy-efficient
- Recylable
Longevity
- 20 years, more or less, depending on maintenance, weather, and activity on the roof.
Maintenance
- Requires little maintenance, but a visual roof inspection in the fall and spring is always recommended. When needed, it is recommended to clean with a manufacturer-approved product to improve reflectivity.
PVC Membrane
PVC roofs are a trilaminate membrane made of two thick PVC layers, internally reinforced with a polyester structure. They are often used in commercial and industrial roofing applications. It is commonly used on commercial and industrial roofs.
* Request your membrane sample from your representative.
Components
- Trilaminate polyvinyl-chloride polymer waterproofing system
- Available in various colors such as white, gray and beige
Benefits
- Environmentally-friendly
- Recylable
- Resistant to chemicals
Longevity
- 25 years, more or less, depending on maintenance, weather, and activity on the roof.
Maintenance
- Requires proper annual maintenance, mainly for drains and debris. When needed, it is recommended to clean with a manufacturer-approved product to improve reflectivity.
