TPO Roofing explained

Things You Need To Know About TPO Roofing

TPO is the abbreviation of thermoplastic olefin, which is a roofing material created specifically to cover large commercial buildings. After being produced, sheets of material, which are basically a blend of thermoplastic, rubber or elastomer, and fillers, are welded together using hot air. By avoiding using adhesives and tapes to TPO, roofers create an exceptionally strong bond between the sheets that can be stronger even than the material itself.

Since it is a new product on the market (the production of TPO started in the early 1990s), there is still plenty of room for development. There have been instances of malfunction, such as cracks, which is why efforts are being put into developing the perfect formula for TPO. Anyway, if you wish to choose an energy efficient single-ply material for your building, choose TPO, but make sure you ask your roofing contractor who is well informed of all the pros and cons of TPO.


Installation and Cost

TPO sheets are usually wider and the roofing requires fewer seams. Additionally, TPO is a very light material, making it very easy to install. Since professional and qualified roofing contractor will have no problems installing a TPO roof, you won’t have to spend much money on installation.

The cost of the material itself is not very big either. TPO provides all the benefits PVC has, such as energy efficiency and durability, but it is substantially cheaper, which makes it more and more popular roofing solution in the United States.


TPO has gained a reputation for being a highly energy efficient material like its predecessor PVC. Its color is one of the reasons. TPO usually comes in white or light gray, which helps to reflect the sun’s rays, making the surface cooler in the summer. During hot months, it will easy to save money on excessive air-conditioning, since the temperature in the areas inside the house will be lower, thanks to the TPO roofing system.

It is very resistant to temperature changes: it will not shrink or expand to a large extent like some other single-ply materials. TPO is also resilient against mold, mildew, fungi, algae, cracks, punctures or other mechanical damage, which makes it better than other thermoplastic roofing materials. UV radiation can considerably damage your roof, but TPO offers excellent protection from ultraviolet rays, too.

TPO is also a completely recyclable material, which a major factor to those who wish to install an environmetally friendly roofing system. Also, its role in UV protection and energy saving also contributes to the environment, since it reduced the so-called heat island effect in big cities.


Potential Risks

TPO is a relatively new roofing solution designed to combine the benefits of EDPM and PVC while trying to avoid the disadvantages of other single-ply systems. But the reality is far from the truth, which is that TPO’s formulas are still being tested daily by professionals. Due to its young age, it is now impossible to say how long will a TPO roof last, which can hinder the decision of homeowners and residential building owners to have a TPO roofing system installed.

In order to make the best decision, be sure to find a roofing contractor who has enough experience and knowledge when it comes to TPO roofing.
