A thermoplastic olefin (TPO) roof is a roof made of single-ply roof membranes designed using ethylene propylene rubber. These membranes are meant to combine the sturdiness of EPDM rubber with the exceptional performance of the hot-air sealable closures. TPO membranes have proved to be reliable roofing materials with excellent resistance against ozone.
They are also resistant to algae and are friendly to the environment. Another reason why these roof membranes are so popular today is that they are easy and safe to install. Continue reading to learn more about TPO roofing.
How to Install TPO Roofing
The installation process of a TPO roof starts with the removal or scrubbing of the existing substrate. Then, you have to install the insulation. There are various types of insulation options that you can choose for your roof, including polyisocyanurate, expanded polystyrene (EPS), and extruded polystyrene (XPS).
Once you have installed the insulation, it’s time to place the TPO membranes. These membranes can either be attached to the cover board with a bonding adhesive or be mechanically fastened. Once the membranes are fully rolled out, you should use a hot-air gun to bond the seams.
Benefits of Installing a TPO Roof
One of the main reasons property developers prefer TPO roofing over other options is their reasonable costs. Moreover, TPO offers PVC roofing benefits, including hot-air sealable seams and improved energy efficiency, albeit at a lower cost.
Matches Different Architectural Styles
TPO roof membranes are designed to match different architectural styles. In addition, they are available in various colors, including white, grey, black, among others. All these colors are highly reflective to reduce your energy costs. These membranes are also constructed using the latest technologies to enable them to resist harmful UV rays.
Unlike other roofing materials, TPO membranes are designed to resist mold growth, accumulation of dirt, punctures, and impact. They are flexible and allow a building’s movement and settling. Also, if your TPO membranes are reinforced, they can withstand your building’s thermal expansion and contraction to avoid cracks.
Easy to Install
TPO membranes normally have more comprehensive sheets and are lightweight. Therefore, they are easier to install. This also means that they cost less to install.
If you are looking for a roofing option that will enable you to save on your air conditioning costs, TPO roofing is an ideal choice. Their white reflective surface even exceeds the EPA’s energy star requirements.
