Key Advantages of TPO Roofing

Thermoplastic polyolefin, or TPO, roofing is one of today’s most popular single-ply commercial roofing systems, often referred to as “plastic” roofing. In today’s post, Sully-Jones Roofing discusses the advantages of TPO roofing for commercial facilities.


TPO Roofing


Single-Ply Roofing Systems


A typical single-ply roofing system consists of a layer of membranous material that covers a substrate. The outer layer is built from sheets of a single-ply material that’s welded using heat or adhesive, covering the roofing area like a blanket. Depending on the material, it can be installed fully-adhered to the substrate, mechanically fastened at the seams or laid loose and weighed down with ballast.


TPO was introduced in the 1990s as a cost-efficient alternative to PVC or vinyl single-ply roofing systems. Standard TPO membranes consist of three layers — a TPO polymer base, scrim (a chemically-bonded fabric layer that acts as a reinforcing layer) and the TPO outer layer. Vent pipes and other similar roof penetrations are protected at the base with sealant and rubber boots, a cone-shaped type of flashing.


Advantages of TPO Roofing


The following are some of the key features of TPO roofing systems.


Repairable. Roof repair can be easily conducted on TPO roofs. Punctures are fixed using heat or adhesive-applied patches. Damage to the substrate can be fixed without affecting most other parts of the roof.


Cost-effective. TPO roofing costs are relatively lower per square foot, which can help shave off some dollars from your estimate if you are covering large areas.


Flexible installation process. As described above, TPO roofing can be installed in more ways than one, which can help reduce labor costs. The simpler the installation process, the quicker and less labor-intensive it will be. This will give you the option to weigh the best installation process that works with your budget.


Durability. TPO roofing has a flexible outer layer that makes it more resistant to light punctures and searing. TPO is also naturally bacteria and algae-resistant, which helps prevent algae formation in case of ponding water.


Energy-efficient. A TPO roof has a reflective outer layer, which helps deflect ultraviolet (UV) radiation and radiant heat. This helps fend off degradation caused by UV radiation, as well as reduce radiant heat absorption. The less heat that’s absorbed through the roof, the lower the indoor cooling requirements will be, resulting in energy savings and comfortable spaces for your clients. Most TPO roofing bears certification from ENERGY STAR®.
