It’s important to note that there are pros and cons to each type of commercial roofing system. Even though we will address the most common TPO roofing problems in this article, TPO systems are durable and long-lasting when professionally installed and maintained. 

TPO roofing systems are roofing membranes made from Thermoplastic Polyolefin. It’s more durable than EPDM rubber and PVC membranes, and TPO systems have many benefits, including the following:

  • TPO roof material is watertight.
  • The material is flexible in colder temperatures and can expand and contract without breaking. 
  • TPO surfaces don’t crack or break down when exposed to ultraviolet light or extreme temperatures. 
  • TPO roofing systems are popular in warmer climates because the surface offers excellent resistance to UV rays. 
  • TPO roof systems are resistant to environmental pollutants and chemicals.
  • TPO can be applied to some existing roofing materials. 
  • TPO roof may last 20-30 years if properly installed and maintained. 

As you can see, TPO membranes can increase the lifespan of your roof. However, some problems can occur if TPO roofs aren’t expertly installed or maintained.

Problems With TPO Roofing Systems – and How to Solve Them

Your roofing contractor should tell you what problems to look out for – especially if you are new to this type of roofing system.

Surface punctures in TPO roofs

TPO is a single-ply membrane, so problems occur when the surface is punctured. 

Avoid punctured surfaces by limiting foot traffic and reducing the likelihood of falling limbs and other debris from landing on your rooftop.

Peeling or bubbling TPO membrane 

If the TPO roof surface is peeling or bubbling, this is almost always a sign that the system was not correctly installed. Proper installation guidelines dictate that the roof deck is clean, solid, dry, and stable for maximum adhesion. 

If you notice membrane failures of this kind, contact your commercial roofing contractor.

Leaks forming at seam joints in your TPO roofing system

TPO roofing systems feature scrim reinforcement and hot-air welded seams. If you use an expert roofing contractor for your TPO installation project, the problem of uneven or leaky seams shouldn’t arise. 

As soon as you notice problems, contact your commercial roofing company to inspect and repair the roofing material. Also, make sure that your gutter and drainage system is working correctly, as pooling water can lead to further degradation of seams and will cause the problem to reoccur.

How to Prevent TPO Roofing Problems 

Like most things in life, there are things you can do to prevent roofing problems. Here’s how to get the most out of your TPO roofing system.

Complete regular inspections. Regularly check the condition of your TPO roof system. Some TPO manufacturers require professional inspections in the warranty. 

Keep the roof surface clean. A dirty TPO surface can’t act as a solar reflective membrane. Remove dirt, debris, and grime from your roof, and make sure your gutters are working correctly. 

Contact your roofing contractor if you notice a roof membrane problem. TPO roofing material is not indestructible. If you see signs of damage, schedule an appointment with the installer or another highly-rated company in the commercial roofing industry.
