Single Ply (Membrane)

Single-ply membrane roofing, is a roofing system that incorporates wide rolls of either rubber or synthetic blends that are melded together to create a protective membrane for your building’s roof. There are two main types of single-ply systems: EPDM (Ethylene Propylene Diene Terpolymer) and TPO (Thermoplastic Polyolefin).

EPDM roofs have been used on industrial roofs for over 65 years, commonly known as “Black Roofs” for their colour. They offer excellent heat retention and elasticity, making them more popular in colder climate regions.
TPO roofs, are commonly known for their white roofs (Although available in other colours) - making them the choice for “Green Roofs” as the highly, heat reflective option. Although the newer of the two systems (In use for about 20 years), it is rapidly gaining popularity, particularly in warmer climate regions.

Although relatively cheaper in cost and easier to install, unlike Built-Up-Roofing (BUR) systems, they do not have a protective top layer. Due to this, they are much more susceptible to punctures and therefore leaks. Manufacturers do offer varying levels of membrane thickness, that also affect the length of warranties offered. Also, due to the nature of commercial/ industrial roofs, with its many accessories in the forms of vents, HVAC units, plumbing, sky lights… etc., the membrane rolls need to be cut into smaller pieces around these items. This further compromises the integrity of membrane (single-ply) roofs, along with its nature of the seam-sealing adhesive installation process as well as the degrading effect of UV rays on said adhesives. Due to this, single-ply membrane roofs may be more susceptible to leaks than other systems.

Built-Up Roofing (Asphalt) - 3/4/5 Ply

This is the oldest method and most commonly found amongst older buildings; this system has been in use for over 100 years! Also known as “asphalt” or '“tar and gravel” roofs due to the use of these materials in their construction, is a more labour intensive procedure. A tried and tested method, it involves a base sheet that is fastened to the roof to flatter, workable surface proceeded by 3 to 5 layers (plies) of waterproof fibreglass sheeting sandwiched between layers of asphalt (tar). The top layer is commonly an either asphalted (but not necessarily) layer of gravel or river rock, as a protective layer against UV rays, punctures, wind, and extreme weather.

The general rule with Built-Up Roofing is that more is better. Unlike single-ply roofing, if a layer is punctured and/or water leaks through, it has to make its way through many more layers to infiltrate. Built-Up Roofing is also generally known for its low-maintenance and reliability. Gravel / river rock is also a great UV ray reflector and excellent fire-retardant.

That being said, this comes at a cost - Built-Up Roofing is a method that naturally adds more weight to a roof and may not be the choice for all building structures. Also, due to the labour and workmanship involved (including the use of asphalt and/or torching), it is generally a relatively lengthier install process and costlier. It also dependent on what the building owner chooses to fit their needs and/or budget (3/4/5-Ply, gravel, river rock etc…). Also, as mentioned the use of asphalt, specifically its smell, may or may not be off-putting to occupants; but recent advancements in technology give us the potential to minimize or even neutralize the smell of asphalt.

Modified Bitumen (2-Ply/ Torch-down)

Considered the natural evolutionary development of Built-Up Roofing, this method involves the use of three-foot wide rolls, comprised of asphalt combined polymerized rubber, reinforced via fibreglass or polyester. This results in a flexible, yet highly durable waterproof membrane that is highly advantageous in holding up to our erratic Canadian climate. - given the propensity of buildings to shift due to temperature extremes.

First, a smooth base sheet layer is installed followed by the modified bitumen rolls, which are granulated on top.
Modified bitumen rolls applied typically “torched-down” in a staggered manner, but there are also newer peel-and-stick alternatives. Due to the general convenience of this method, many choose to use “torch-down” as their method of choice to repair older BUR roofs.
