All About TPO Roofing: Cost, Benefits And Installation

All About TPO Roofing Cost, Benefits and Installation (2)

When it comes to choosing the right roofing material for your building, there are many options to consider. One popular choice among commercial and industrial buildings is TPO roofing. 

TPO roofing was first introduced in the early 1990s as an alternative to traditional roofing materials like built-up roofing (BUR) and modified bitumen. Its popularity quickly grew as building owners and contractors discovered the many benefits it offered. Today, TPO is one of the fastest-growing roofing systems in the industry, with an estimated market share of around 40%.

So what exactly makes TPO roofing so attractive? Let’s take a closer look at its features and advantages.

What Does TPO Roofing Stand For? 

What Does TPO Roofing Stand For

TPO stands for Thermoplastic Polyolefin, which is a type of single-ply roofing membrane. This material is made up of three layers – a TPO polymer base, a polyester-reinforced fabric center, and a thermoplastic polyolefin-based top ply. 

These layers work together to provide superior strength, durability, and resistance to harsh weather conditions.

TPO Roofing Details 

TPO roofing is a popular choice for commercial and industrial buildings due to its lightweight, flexible, and cost-effective nature. Unlike bitumen roofing, It can be easily heat-welded together, making it a seamless roofing system that provides excellent protection against leaks.

The TPO polymer base layer is typically white in color, which reflects the sun’s rays and helps to keep the building cool. This also makes TPO roofing an energy-efficient option, as it reduces the need for air conditioning during hot summer months.

How To Install TPO Roofing?

How to Install TPO Roofing

Installing TPO roofing requires a few key steps to ensure a successful and long-lasting roof. Here’s an overview of the installation process:

  1. Prepare The Roof Surface: The first step is to clean and prepare the roof surface where the TPO membrane will be installed. This typically involves removing any debris, dirt, or old roofing materials.
  2. Install Insulation: Next, a layer of insulation is added to provide additional protection and energy efficiency for the building.
  3. Lay Down Membrane Sheets: The TPO membrane comes in large sheets that are rolled out onto the prepared roof surface. These sheets are then cut to fit around vents, pipes, and other protrusions on the roof.
  4. Heat-Weld Seams: Once all the sheets are laid down, the seams must be heat-welded together using a specialized welding machine. This creates a strong and waterproof bond between the sheets.
  5. Add Flashing And Edge Trims: Flashing is installed around any edges or corners to provide extra protection against water penetration. Edge trims are also added to secure the membrane in place.
  6. Perform Final Inspections: A thorough inspection should be done to ensure all seams are properly welded, and there are no punctures or tears in the membrane.

What Are The Common TPO Roofing Colors?

TPO roofing is available in a variety of colors, including white, light gray, and tan. White is the most popular color for TPO roofing as it reflects sunlight and helps to reduce cooling costs. 

However, some manufacturers also offer custom colors or patterns for a more unique look.

Are All TPO Roofs White?

No, TPO roofs are not all white. While white is the most common color due to its energy-saving properties, TPO roofing is also available in other colors such as light gray and tan. 

Can A TPO Roof Be Painted?

Technically, TPO roofing can be painted, but it is not recommended. The material is specifically designed to reflect sunlight and painting it can compromise its energy-saving abilities. Additionally, the paint may not adhere properly to the TPO surface, leading to potential roof damage or discoloration over time.

It’s important to note that painting a TPO roof may also void any warranties from the manufacturer or installer. If you are looking for a specific color for your TPO roof, it’s best to choose from the available options provided by reputable manufacturers.

  8. Fire-Resistant: TPO membranes have a high fire resistance rating, providing an added layer of protection for commercial buildings and their occupants.
  9. Reflective Properties: TPO roofs have reflective surfaces that can help reduce energy costs by keeping buildings cooler during hot summer months


  1. Limited Color Options: TPO roofing is only available in white, gray, and black colors, limiting design options for building owners.
  2. Susceptible To Punctures: While TPO roofs are durable, they can still be punctured by sharp objects or heavy foot traffic.
  3. Not Ideal For Extreme Temperatures: TPO roofing may not hold up as well in extremely hot or cold climates, making it less suitable for certain regions.
  4. Potential For Shrinkage: If not properly installed or maintained, TPO membranes can shrink over time, causing issues with the roof’s integrity.
