TPO (thermoplastic polyolefin) roofing systems are constructed of rubber and synthetic materials. This type of membrane will protect insulation and decking materials that comprise your place of business' rooftop.

TPO Roofing Materials

TPO products come in single sheets. A manufacturer sells products that are varying widths. Once the TPO products are manufactured, they are rolled up and shipped to worksites. A single-ply layer of TPO is installed over the roof decking and insulation.

TPO products contain a synthetic underlayment. This material is bonded to the underside of a TPO membrane. The underlayment adds strength to TPO materials.


TPO products are reflective. They keep energy costs down. The bright white color of a TPO membrane will improve the aesthetics of a commercial building's rooftop. A TPO membrane is designed to conceal the insulation and decking materials that are located underneath the TPO layer.


The cost of a TPO installation will be dependent upon the condition and size of a commercial rooftop. A roofing crew may need to rip off old roofing materials or conduct some cleaning processes. These steps could drive up the cost of having a TPO roofing project completed.

The design of a rooftop could also affect the cost. TPO membranes are typically installed on rooftops that possess a flat design.


If you have decided to have a TPO membrane installed on your business' rooftop, a contractor will schedule the inspection of your building. After you receive a quote, the contractor will order TPO rolls from a manufacturer.

There are various ways to secure TPO. A ballast process will require the use of flashing materials. The TPO will not be anchored directly to the roof decking.

A mechanical fastening process or an adhesive fastening process can also be used. With either of these processes, the TPO membrane will be anchored to the decking.

Your contractor will describe the different installation processes that can be used to attach the TPO materials. A heat gun will be used to permanently attach the edges of TPO pieces.


TPO membranes typically last for many years. Inclement weather, however, could cause a TPO membrane to become damaged. Small holes in a membrane could lead to insulation becoming saturated. If larger holes form in a TPO membrane, excessive rainwater could leak into your place of business.

A contractor will need to determine if TPO sections can be patched or will need to be replaced. If TPO can be repaired, a contractor will patch the holes and add a protective layer across the entire membrane.
