For commercial buildings, TPO roofing systems are a common option. Due to their durability, they are becoming very popular for residential roofing as well. It is simple to install, an affordable option, and also resistant to UV radiation. But it also has its flaws, which you should know before considering installing TPO.
This guide will discuss what TPO is, its advantages and disadvantages, and its life expectancy.
What is TPO Roofing?
Thermoplastic Polyolefin (TPO) consists of polyester reinforced fabric scrim, polymer base, and a top layer of thermoplastic polyolefin, giving it exceptional toughness and durability. It’s relatively newer to the commercial roofing sector, having only been present since the early 90s. It’s classified as a single-ply roofing membrane. TPO has adhered chemically and mechanically into single-ply membranes having heat-weldable seams.
They are most popular among commercial buildings with low slopes and flat roofs.
Advantages of TPO Roofing
Insulation Options for Customers
Single-ply roofing requires insulation, which leaves clients a choice to have a wider range of alternatives for insulating their facility’s roof.
They are usually white and very reflecting.
During the manufacturing process of TPO, they have added fire retardant chemicals to give fire protection to roofing.
Due to their excellent reflective property, they reflect heat away from the structure, which helps save energy costs during hot weather. This helps reduce costs to keep the building cool under the scorching Florida sun.
The U.S. Environmental Protection Agency’s criteria are frequently exceeded by TPO roofing systems. It’s also 100 percent recyclable and promotes structures in meeting LEED goals.
Exceptional Wind Ratings
Because of the powerful winds involved with regular hurricanes in Florida, TPO provides high wind ratings and can withstand hurricanes.
TPO provides a durable solution for residential and commercial properties from contact damage, falling branches, and tears. They are also resistant to mold and algae growth, chemical and liquid spills, and debris collection.
Disadvantages of TPO Roofing
It Is Weakened By Lamination
Laminating the surface layer of TPO thermoplastic roofing material is common. With time, this can result in weak areas, contraction, fractures, and degradation. TPO roofing that is inexpensive might develop surface fractures fast.
Based on the manufacturer, it might be challenging to find consistent quality TPO roofing.
Might Go Through Contraction and Expansion
TPO roofing material is available in smaller sizes, implying it has many seams. As a result, they might go through expansion and shrinkage. This can ultimately cause the seams to come loose, enabling water to seep into the roof.
TPO Life Expectancy
TPOs have a lifespan of fifteen to twenty years. The membrane can become pierced, seams can detach, and flashings can collapse, resulting in a leaking roof. Water entering the structure is the first clue that a TPO roof needs to be repaired.

TPO has several advantages. It may survive a lot of years if correctly installed and get checked for maintenance regularly. It will continue to provide energy efficiency and UV protection for the best performance.
