Thermoplastic Polyolefin

It is a single-layer type of flat roofing system designed using synthetics with a width that ranges from 10 – 20 feet. This is a surface that can naturally reflect ultraviolet rays that’s why it has gained popularity and acceptance in the construction industry.

Aside from that, it is also a budget-friendly option and may last for 10-20 years or more. Just like PVC, it comes with properties to help you save energy. Since this is welded, leaks can be prevented and that is a big help because maintenance is less required.

Installation

The workers may clean or remove the roof, depending on how they have planned to prepare the substrate, and then they will install the insulation. However, you will have to choose from the insulation types.

We have Polyisocyanurate, which is more expensive but is commonly used because the R-value rating is high. Your other option would be the Expanded Polystyrene which has the highest R-value rating because it can also be installed on the wall, floor, and ground since it won’t allow water to retain for a long time. The last option would be Extruded Polystyrene which semipermeable and usually come in green, pink, or blue color.

Adhesives or mechanical fasteners are used to attach the TPO to the board. Hot-air guns are also used to weld the seams.

Advantages

With flat TPO, you can choose the right insulation to install in your facility. I guess this makes it a good option for some consumers.

While manufacturing the membrane, you will have the chance to add chemicals like fire retardants. This is why the Underwriters Laboratories gave them a fire rating of Class A – click here for more details.

The color is white in general and it is extremely reflective. It will always be a great feature to be efficient. So, this helps the facility in saving energy.

When to repair

It will take you more than 20 years before repairing a flat roof with TPO material. When this time comes, the seams may have been ripped apart, have flashings failed, or punctured membrane. I guess you may also experience leaks on the insulation, so it calls for a repair or replacement.

The first thing that you should do is to ask a contractor for an inspection to have a better look at the problem and to determine possible solutions. They may use infrared for measuring the saturation because the insulator may have a problem.

Well, when the experts were able to locate the problem and how much is affected, they will tell you to repair it. However, some commercial building owners from Portland prefer the installation of new ones since this will last for another 20 years.
