How To Repair TPO Roofing

If you manage a commercial property, chances are you've had to deal with TPO roofing at some point.

TPO is a popular choice for commercial roofs because it's durable and relatively inexpensive. But like all roofs, TPO can develop problems over time. In this blog, we'll talk about the process of repairing some common issues with TPO roofing. 


What Is TPO Roofing?

TPO roofing is becoming increasing popular for commercial properties due to its strength and durability. This low-maintenance material can last for many years if it is properly cared for and maintained, often lasting longer than traditional materials such as asphalt shingle roofs. TPO roofs are made from thermoplastic polyolefin (TPO) rubber or PVC plastic with an added layer of protective coating, making them less susceptible to damage from hazardous elements like UV rays, extreme temperatures, pollutants, severe winds, and fire. These qualities make TPO roofing a great long-term investment that offers a range of environmental benefits such as improved energy efficiency and reduced carbon footprint.


The Most Common Issue With TPO - A Punctured Membrane

It may be tempting to write off cracks and holes in TPO roofing as 'just part of the job'. It's important to keep in mind though that interior and exterior damage can happen more quickly than you'd expect - especially during colder months. If you notice any cracks or holes in TPO roofing, it's essential to schedule repairs promptly. Ignoring the issue may come at a cost further down the line when larger repairs are needed. Getting it repaired at first sight can save you a lot of headaches and money in the long run.



How Is TPO Roofing Repaired?

TPO roofing is relatively easy to repair, as long as the issue is not with installation (if that's the cause of your problem, you may be looking at extensive repairs or even a full replacement). But if you're looking at the most common issue seen with TPO roofing - cracks or holes in the membrane - it's repaired with just a few easy steps.


Thoroughly Clean The Area

Repairing TPO roofing starts with the right preparations. First, the area around the hole or crack needs to be cleaned using a brush or a garden hose. Debris and dirt need to be swept away to get a smooth surface to work with. While cleaning, keep an eye out for any loose stones or gravel that might have settled in between the cracks; these should be removed so that there’s no risk of them getting sealed into place when you repair the roof.


Apply Adhesive Sealant To The Area

In order to fill any gap left by mounting repairs and ensure a strong bond, the next step in repairing TPO Roofing is to apply a generous amount of adhesive sealant to the damaged area. It's important that an even application is used in order to guarantee it creates a secure, waterproof seal. Once applied, the sealant will need to cure and dry completely before any exposure to moisture for optimal performance.


Apply A TPO Patch

One the adhesive sealant has dried, a patch of TPO roofing material will then be applied over the hole or crack. A seam roller is necessary to firmly press it down and secure it into place. This process will help ensure that no moisture can penetrate beneath the patch, which could lead to further issues if not corrected. The patch should then be covered with a liquid membrane TPO coating for additional protection and improved longevity.


Smooth Out The Patch

When repairing a roof, it's important to take the time to ensure that the patch is properly smoothed out. An efficient way to do this is to use either a roller or brush - whichever tool works best for the material you're dealing with. Rolling or brushing the patch evenly and in one direction will ensure that it blends seamlessly with the existing roof, thereby maximizing its structural integrity. Furthermore, smoothing out any remaining ridges and crevices with a sponge or cloth can help create an even finish. Finally, while some people opt to apply sealant to such a patch, doing so is unnecessary if the process was done correctly.
