Do you have a thermoplastic polyolefin roof? If so, it's important to keep an eye on it and make sure that it's in good condition. A thermoplastic polyolefin roof is a popular choice for many businesses and homeowners. It is known for its durability and resistance to weathering. Although a TPO roof typically has a long lifespan, regular inspections by a roofing contractor are important to ensure that there are no visible signs of damage. Here are three signs that your TPO roof may need an inspection.

1. The Roof Is Blistering or Bubbling

Blistering occurs when moisture gets trapped between the membrane and the insulation, causing the membrane to swell and deform. Bubbling, on the other hand, occurs when there is a loss of adhesion between the membrane and the insulation. This can happen for several reasons, including improper installation, poor maintenance, or exposure to chemicals. In either case, the end result is the same: the membrane is no longer able to protect the building from weather, wind, and UV radiation. As a result, it is important to have your TPO roof inspected by a qualified roofing contractor as soon as you notice any blistering or bubbling.

2. The Sealant Around Vents and Pipes Is Cracked or Peeling

The sealant is what keeps water and other elements from entering these vulnerable areas. If the sealant is damaged, it can allow water and other contaminants to enter the building, which can lead to serious problems such as mold and rot. In addition, the sealant protects the building from UV radiation. If it is damaged, the building will be more susceptible to heat damage.

3. There Are Discolored Areas on the Roof

These discolored areas are usually caused by algae or mold growth. Although not all algae and mold growth are harmful, some types can cause significant damage to the roof. In addition, discolored areas on the roof can be a sign of other problems, such as leaking. Leaks can cause serious damage to the structure of the building, and they can also allow water and other contaminants into the building, which can put your employees at risk. If you notice any discolored areas on your thermoplastic polyolefin roof, you should have the roof inspected.

If you notice any of these four signs, it's time to call a roofing contractor to have your roof inspected. Doing so will help to ensure that your roof continues to protect your building from the elements.
