What is TPO Roofing?

TPO stands for Thermoplastic Polyolefin is a single ply membrane roofing used mainly for flat commercial roofs. It is one of the fastest-growing and most popular commercial roofing systems on the market TPO roofing membrane is made up of 2 layers of synthetic with reinforcing scrim. 


TPO is a heat-weldable membrane that does not require the use of any volatile organic compounds (VOCs) during installation. As a result, TPO offers many benefits, including high reflectivity, UV resistance, and energy efficiency. It is also one of the most cost-effective commercial roofing solutions available today.

There are three main types of TPO roofing systems:

  1. Ballasted – This system uses large rocks or gravel to hold down the membrane. This is a good option for flat roofs that cannot support the weight of a more traditional roofing system.
  2. Mechanically Fastened – The membrane is attached using fasteners and plates to the flat roof deck. This is a good option for flat roofs that cannot be welded.
  3. Fully Adhered – In this system, the membrane is glued or welded to the flat roof deck. This is the most vital TPO roofing system used on new construction projects.

TPO roofing systems are composed of two main layers:

  1. The base layer – This layer is typically made of polyester or fiberglass and reinforces the membrane.
  2. The top layer – This layer is made of a synthetic rubber compound, such as ethylene propylene diene monomer (EPDM), chlorosulfonated polyethylene (CSPE), or neoprene. This layer provides UV resistance and durability.

TPO roofing systems are available in various colors, including white, tan, and black. White TPO membranes are the most popular choice for commercial roofs because they reflect sunlight and help keep buildings more fabulous in the summer. However, tan and black TPO membranes are also available and can be used to match the color scheme of your building. You can find more topics here at, roofing repair specialist blog.

TPO roofing systems are usually installed correctly by certified professionals using special equipment. The membrane is first unrolled and then welded together using a hot air gun or an electron beam welder. Once the seams are welded, fasteners or adhesive attach the membrane to the roof deck.

If you are considering a new roof for your commercial building, a TPO roofing system is a great option. TPO roofs are durable, energy-efficient, and cost-effective. They are also available in various colors to match the look of your building. Contact a local TPO roofing contractor for more information about TPO roofing systems.

TPO Roofing Installation


After the existing roof is prepared, the insulation board is installed either by cleaning or removing the existing roof. There are several variations of insulation board or separation sheets for each customer to choose from based on their budget or requirements.

TPO Membranes come in various thicknesses and widths, varying from 4 ft. wide to 20 ft. wide. The thinner the membrane is usually, the shorter the cost and warranties. However, the thicker the membrane, the more long-lasting it will be.

The TPO membrane can then be installed by mechanically fastening it or using a full-coverage bonding adhesive.

Once the membrane is installed, it is vital to finish off by adding either a gravel ballast or a white TPO mechanically fastened system to protect the membrane from UV rays and extreme weather conditions.

TPO Membrane installation can be completed in a few days, depending on the size of your roof and the number of people working on it. It is vital to make sure that you hire a professional commercial roofing contractor with experience in installing TPO roofs.
