what is a TPO roofing system?

A TPO or thermoplastic polyolefin roof is a single ply flat roofing material that covers the entirety of the roof and allows easy systems access. While not actually plastic, the material is more so rubber material that offers flat roof owners quite a few benefits as opposed to other flat roofing materials. Being one of the toughest modern roofing materials developed, TPO roofing offers significant advantages in impact and weather resistance. What it may lack versus other roofing materials it absolutely gains in durability and resistance to the buildup of several things that plague other roofs. Those things include:

  • Algie 
  • Bacteria 
  • Dirt

TPO roofing installation will also provide your home or business resistance to UV rays as well as chemicals that normally prove detrimental to roofing materials. How that works is that due to the coloration of TPO roofing, UV rays bounce off the surface and are effectively reflected. In instances of most chemical spills, TPO roofing resists the result similar to how it proves highly effective against rainwater. With TPO roofing installation, you will see far fewer tears in the flat roof material that will last the owner over two decades of solid service. Furthermore, when installed by a solid roofing contractor, such as Legends Roofing in Dallas, TX, you will see each benefit applied to your business or home immediately.

How is TPO roofing installed?

A TPO roofing system offers plenty of advantages that take effect only when installed correctly. There is more than one way for installation when it comes to TPO. However, there is a process before installation can be done that is shared between each. Before the installation is considered, the surface must be cleaned and clear. That means no debris or dirt and a definite lack of moisture on the surface of what is about to be the interior of the roof. This assures that the roofing system will be free or mostly free of blisters and wrinkles on the surface when it is fully installed. It also maintains that the method of installation is fully adhered to, avoiding the chance of failures in the form of blowoffs. 

Moving on to the actual moment of installation, there are two methods that are the primary techniques that will maintain full adhesion for the TPO roof. Those are using incredibly powerful adhesions and superheating. It is not uncommon to use both methods together and still have a highly effective result on the outcome. When the surface is well prepared, sections are laid down and applied to the adhesive. Then being let sit and carefully inspected to make sure it brings the correct result. 

What is the difference between TPO and EDPM roofing?

There are several different types of flat roof materials that can benefit your business or home and can effectively protect it from weather like hail as well as impacts on the roof. However, when deciding on whether to get ethylene propylene diene monomer or thermoplastic polyolefin there is a superior material that will better get the job done for the designated purpose of being your roof. Better known as EPDM rubber roofing and TPO roofing, both are resistant and easier to apply. However, TPO wins out against EPDM by:

  • EPDM absorbs sunlight and put undo stress on air conditioning systems
  • TPO is far tougher than EPDM against punctures and impacts

Both flat roof materials are known to be tough against weather and rain, but when it comes to things like hail and wind TPO roofing is considered to be superior compared to EPDM. Even when on the rare occasions either has seams showing on the surface, TPO proves to be better resistant.

How do you repair TPO roofing?

Upon scrubbing down the area around the damage, the owner or roofer would put down the sealant and the TPO roofing material before placing down the tape that would cover any openings that might be there in the adhesive. It should be noted that this should be treated as a short term measure, the tape does not last nearly as long as seamless TPO. 

When it comes to cleaning, TPO roofing is rather easy compared to most roofing materials both flat and other. It can be done in more than a few methods aside from waiting for the next shower to pass through the area. Many people use power washers, on lower settings so as not to damage the roofs, and making sure to cover the entire roof while being careful at spots where systems are present. Another solution can be to take a brush or broom and coat it with a detergent solution. Washing your roof with that and water does the job effectively as well. Both done in a system are also possible. Either way, you will want experienced roofers for the job either in case damages arise or for the most effective and thorough cleaning.
