Single Ply roofing membranes have grown in popularity over the past 30 years due to their flexibility, relative ease of installation, and competitive price.
EPDM (Ethlyene Propylene Diene Monomer)
EPDM roofing systems, also known as single-ply systems, are factory-fabricated, rubber-roofing membranes, which are available in several thicknesses. Primarily, they are synthetic single-layer sheets of ethylene propylene diene monomer. EPDM systems can be installed using a variety of methods, including loose-laid and ballasted, fully adhered, or mechanically attached means. EPDM membranes are known for their long-term weathering ability, and perform well even when subjected to fluctuations in temperature, ultraviolet rays, and ozone.
PVC (Polyvinyl Chloride)
This roofing system is similar to the EPDM system. However, its synthetic single-ply membrane sheets are made of polyvinyl chloride (PVC). These membranes are available in a variety of thicknesses and colours.
TPO (ThermoPlastic Olefin)
Similar to EPDM and PVC systems, thermoplastic polyolefin (TPO), roofing systems combine both polypropylene (plastic) and ethylene-propylene (rubber) using state-of-the-art polymer manufacturing technology. The result is an ideal commercial roofing system that is reliable, cost effective, environmentally friendly and easy to install. Systems can be installed fully adhered or mechanically fastened. A complete line of accessories, sealants and adhesives is also available.
This type of roof system uses modified bitumen membranes, which are factory-rolled products with rubberized or polymeric asphalt applied to one side at the factory. It can be installed by mopping on hot asphalt to adhere the membrane to the roof or, more commonly, by using a propane torch to heat the underside of the coating. Melting to a near-liquid, the membrane is then rolled onto the roof in a continuous operation.
Built-up roofing, which has been used for almost 150 years, is one of the oldest and most durable roofing systems. The system consists of multiple plies of reinforcing felts laid shingle fashion into continuous moppings of hot asphalt or cold adhesives. The system is then covered with aggregate set in an asphalt flood coat or final cold adhesive application. The plies can consist of organic membranes or glass fiber membranes.
Built-up roofs are particularly resistant to damage from wind, hail and snow. The multiple layers provide extra protection and perform well in extreme weather conditions.
