Thermoplastic Olefin/Polyolefin (TPO) roof membranes and Polyvinyl Chloride (PVC) roof membranes are among the most common of single-ply membranes associated with roofing. These are flexible sheet materials that are commonly used in one layer, or one ply, configurations. Often comprised of ethylene propylene rubber, these roof membranes are made up of chemical and physical characteristics that enable them to soften over time when cooled and heated repeatedly. This makes them greatly heat-reflective and energy-efficient systems for roofing, delivering continual resistance to ozone, ultraviolet and chemical exposure.

Furthermore, the sheets of TPO single ply membranes are typically seamed by heat which is welded with hot air.

When TPO roof systems have been installed properly, their lives range from anywhere between 10 and 20 years. The type of installation can play a significant role regarding which end of the spectrum the life of a roof lands on.

When it comes to deciding whether a single ply roofing membrane system is right for your structure, you should first consider whether the building is made to suit a single ply membrane.

Single ply membrane roofing is most appropriate when the roof has adequate slope, when re-covering an existing membrane, when structural movement is anticipated or if cold weather is a factor, among other factors.

A TPO roofing system is glued or fully-adhered to the substrate with a special adhesive that enables the glue to create a type of chemical bond with the existing membrane. These membranes use a special screw-type fastener in order to secure the new roofing.

Benefits of TPO Roofing

TPO roofing systems are both energy-efficient and are one of the most economical options for large and low slope roofing areas that require no rooftop equipment in order to maintain. They do need to be cleaned annually.
