Pros of TPO Roofing in Houston

Energy efficiency 

The white sheath on a TPO single-ply roofing system reflects the heat of the sun, thus maximizing the effectiveness of facility’s utility. Besides, it helps in reducing the cost of energy. The white TPO single-ply roof also known as “cool roofs,” helps your entire house to maintain a more relaxed interior.


What’s exceptional with the TPO single-ply roofing system is that it can achieve a watertight system warranty for over 25 years subject to your system’s design. Immediately after completing your roofing installation project, the installed TPO roofing will be inspected by specialized technicians for proper detailing and adherence to specifications.


In connection with the cold storage application, the TPO roofing membranes for flat roofs are flexible, make brilliant vapor barriers, and also have low perm rating. Proper system design ensures that the TPO membrane makes more excellent air permeation details in unsafe parts of cold stage construction, for example the wall and roof junctions. Naturally, TPO roof installation is more cost-effective, cleaner and quicker than installing other roofing types.


A TPO roofing system requires less maintenance, but your repairs and maintenance team will be regularly inspecting the roof for any emblems of membrane damage caused by debris. Besides, you can quickly identify punctures or tears on a TPO roof and call for repair.

Wind Uplift Design 

TPO roofing systems are not only robust but also adaptable various geographic locations, such as areas where the roofing systems need to meet and adhere to strict wind uplift standards. Because TPO single-roofing is part of the entire roofing assembly, it must be mechanically-fastened and designed to meet the robust uplift requirements on the market.

Cons of TPO Roofing in Houston

Affected by the heat

TPO roofing membranes tend to have problems due to severe weather when exposed to too much solar or thermal loading. This problem has notably been spotted in southern states that receive a lot of heat as well as sun all year round. A report released by the MRCA committee stated that if conditions may exist that may lead to high temperatures of 160 degrees Celsius and above may increase solar loads beyond the standard limit. As a result, manufacturers are now questioning the suitability of their roofing material for such situation. Consider switching to a different roofing product that will tolerate the loading.
