TPO or thermoplastic polyolefin is a single-ply reflective roofing membrane. It is composed of polypropylene and ethylene-propylene rubber which are polymerized together to form what we call TPO.

This synthetic roofing membrane comes in various thicknesses and dimensions. Usually, customers can find 45 to 80 mils thickness in the market. TPO is typically available in just three colors namely white, gray, and tan. If you want to achieve an energy-efficient cool roof, you can go for the color white which effectively reflects the sun’s energy. This also reduces the building’s energy consumption as well as the urban heat island (UHI) effect.

TPO temporarily shifts from a solid material to a semi-solid state. This happens when it undergoes proper heating treatments. When it changes its state, the sheets or panels are overlapped and combined together to form a solid surface until it cools down.

If you’re curious about TPO waterproofing membrane specifications. Here’s where the magic happens: a TPO’s hot air-welded seams make it 100% resistant to water penetration. Unlike PVC, property owners enjoy a leak-proof roof for a long period of time.

We can go on and on to tell you about the TPO waterproofing membrane specification. However, we think that the message will come across as more effectively if we tell you the consequences of not having watertight roofing.

These are the most common problems that property owners experience if they fail to install a waterproof membrane like TPO flat roofing membranes.

Prone to Leaks

There are different root problems that trigger leaks. Poor installation, substandard materials, and harsh weather conditions are some of the reasons why leakage is a common issue. However, there are certain materials that are prone to leaks like rubber. Over time, it loses its adhesive power, especially at the sides and edges which leads to unwanted leaks.

Areas, where leaks are present, can also be a breeding ground for molds and fungi. They are not only expensive to treat but are also harmful to one’s health.

Structural Damage  

As expected, when leaks start to worsen, water will crawl to other parts of the building or house. It can spill over the walls, ceilings, windows, etc. Once the water reaches the foundation and the base of the property, it can compromise its integrity. What’s alarming about this is that it can go unnoticed for months or years. Chances are it may collapse all of a sudden.

Damage to Interior

Failure to install a watertight material can also damage your interior. When water penetrates the ceiling down to the insides of your home or building, it can wet important things. We’re talking about expensive possessions, devices, electronics, appliances, furniture, and more. At the end of the day, you weren’t able to protect these things from water infiltration which shouldn’t be the case.

Expensive Repairs or Replacements

You have already paid a substantial amount for your roof. However, you will definitely be shelling out more if it’s not 100% waterproof. Premature damages due to water penetration entail costly repairs or even replacements in the worst cases.
