What is TPO Roofing?

A TPO Roof Installation in Progress.

The Advantages of TPO Roofing

As a business owner, you may have heard the term TPO roofing kicked around by commercial contractors and roofers but very few people outside of the roofing industry know what it actually is. However you may want to take some time to familiarize yourself with this material as it could be the answer to some of the building problems you have been encountering. First off, TPO stands for thermoplastic polyolefin.

It is a roof coating that is applied mainly to commercial and industrial type roofs. TPO coating usually comes in rolls and despite the word “plastic” being used in the name, the rolls are actually made out of rubber. In order to provide more protection to the roof itself, the rubber sheets that TPO coatings come in will usually feature a specially laminated upper layer. 

So why would any business owner choose to install TPO roofing over other traditional kinds of commercial roofing like ethylene propylene diene monomer? Take a look at the following list of advantages that TPO roofing brings to the table:

  • TPO Roofing is Economical – One of the main reasons that TPO roofing is emerging as a business owner’s choice is because of the fact that it is so affordable. You can buy TPO coating by the foot and it will more often than not be much more affordable than other kinds of commercial roofing material.
  • TPO Roofing is Great for The SoCal Sun – Another reason why people are shying away from more traditional types of commercial roofing like tar paper is because dark roofing materials like tar paper and asphalt absorb heat. This can make it difficult to cool a large commercial or industrial building. TPO roofing will usually come in white which means it reflects the intense SoCal sun rays as opposed to absorbing them. This makes it much more economical to cool a large building.
  • Long Warranties – Since TPO roofing is so durable and needs little in the way of maintenance, manufacturers typically offer warranties for the material that can last for up to 30 years.
  • Good Wind Ratings – TPO roofing is usually made to achieve high wind ratings which means two things; one, that it will hold up in high winds like the Santa Anas that we get here in SoCal; and two, it may very well lower the property insurance rates for your building. 

Installing TPO

Another reason why TPO is becoming more and more popular is that the property owner has options as to its installation. This allows for more flexibility as opposed to other roofing materials and allows the owner to choose at his or her discretion. Here at Weatherline Reroofing & Repairs Inc. we are capable of installing TPO roofing in the following methods and others as well.

Mechanical Installation 

Mechanical attaching is preferable when time is a factor. This is a very quick method of TPO roofing installation and involves securing the rubber sheets to metal plates that are fastened to the roofing structure itself.

Adhesive Installation

This is a good option if you are a business owner looking to get the longest possible warranty out of your TPO roofing. Adhesive installations usually merit longer warranty periods so that is definitely something to consider. In this method of TPO roof installation, a roofer will actually lay the rubber sheets in place first and then apply a heavy-duty adhesive to the underside of the sheets and the insulation or cover boards of the actual roof.

Seam Installation

TPO roofing can also feature welded seams to protect against leaks and moisture damage. These seams cover all of the breaks in the roofline such as vents, HVAC installations, chimneys etc.

Other Considerations

TPO roofing also performs well in conditions where traditional roofing materials tend to fail. For example, many traditional roofing materials are made out of metal and are therefore subject to rust and corrosion. TPO roofing is made out of rubber and maintains compositional integrity very well. This means that the underlayers of your roof will be better protected since rubber does not rust and corrode.

Mold is also a vital consideration when it comes to your roof. Many roofing materials (especially when  they get a lot of moisture but not a lot of direct sunlight) are susceptible to molding but again, TPO roofing is made of rubber and does not accumulate mold. Additionally, if you opt to heat weld the seams of your TPO roofing you will not have to worry about patching or repairing them any time soon. Heat welding is a superior method when compared to flashing and adhesive seaming.
