Single Ply Membrane

A single-ply roofing system is non asphalt based and uses a single waterproof membrane to seal the roof.  Single-ply roofing membranes have grown in popularity over the past 30 years due to their flexibility, relative ease of installation, and competitive price.  They are manufactured in a factory to strict quality control requirements which provides consistency in the quality of the product.  They also are lightweight so they can be used on irregular roof shapes used in modern architecture.  And they are light-colored and reflective which reduces energy costs.


EPDM is an exceptionally durable manmade single ply rubber roofing membrane (ethylene propylene diene terpolymer) widely used in low-slope buildings in the United States and worldwide.  However, it is very versatile and can also be used on steep slope roofing and buildings with geometrically shaped roofs such as domes and barrels.  It has a long life span, an assortment of assembly reflectivity options, a low carbon footprint compared to other single-ply roofing systems, and it is recyclable.  It can also be installed year round, endures temperature extremes and resists the absorption of moisture.

EPDM comes in a variety of widths and two thicknesses, 45 and 60 mils and can be installed either fully adhered, mechanically attached or ballasted, with the seams of the roofing system sealed with liquid adhesives or specially formulated tape.  It can also be installed above or below insulation and can also be used in below grade waterproofing applications.  In addition to all of that, EPDM is also easy to modify or repair.

EPDM is available in both black and white.  While a white EPDM roofing membrane will offer better reflective properties than a darker colored membrane, an EPDM roof will not offer the same level of energy and financial savings as a TPO roof.


Thermoplastic Olefin (TPO) roofing is a single-ply roofing membrane that has been gaining popularity for commercial flat roofing applications. TPO is made from a mix of polypropylene and ethylene-propylene rubber, which provides a highly durable and versatile roofing solution. The membrane comes in large sheets, in multiple colours but are typically white. These sheets are either mechanically attached, fully adhered, or ballasted to the roof substrate, and the seams are heat-welded to form a watertight seal.

TPO is an excellent choice for commercial flat roofing applications. It combines energy saving, durability, ease of installation and low maintenance costs. TPO roofing is a very reliable and yet low-cost roofing solution for any commercial building. It is free of CFCs and is more resistant to UV radiations, ozone and chemicals. Designed to be environmentally friendly, TPO roofs are flexible and can be installed around all kinds of roof fixtures, air conditioner units and vent pipes.


Polyvinyl Chloride (PVC) membrane roofing is also known as vinyl roofing.  PVC has been around for a very long time and has a proven track record.  It is a flexible thermoplastic membrane that is durable and resistant to harsh chemicals, pollutants and weathering.

The PVC membrane comes in a variety of thicknesses.  Over time, the thinner membranes can become brittle, but the thicker membranes will remain pliable.  PVC has heat welded seams that form permanent, watertight bonds that are stronger than the membrane itself.  And due to their light color, PVC membranes are also energy efficient.  They are also very easy to maintain and repair, even if the roof is 30 years old.

PVC roofing provides an ideal long-term solution offering high performance and a lower life cycle cost when properly installed by certified contractors.
