Do you need a new roof? If so, you may be wondering what TPO roofing is and if it’s the right choice for your home or business. TPO roofing is one of the most popular choices for commercial and industrial buildings, but it’s also becoming increasingly popular for residential roofs. In this article, we’ll explore what TPO roofing is, how it works, and some of the benefits and drawbacks of this type of roofing.

What Is TPO Roofing?

TPO stands for thermoplastic polyolefin. It’s a single-ply membrane that is made from reinforced polypropylene and ethylene-propylene rubber. This combination makes it very strong and resistant to punctures, tears, and UV rays. It is also very flexible, making it ideal for roofs with curves or slopes.

It is installed similarly to other types of single-ply membrane roofing. It’s laid down in large sheets and then heat-welded together at the seams. This creates a watertight seal that is very strong and durable.

Why Do You Need TPO Roofing?

A TPO roofing system is a great way to protect your commercial building. The roofing is a durable, energy-efficient, and cost-effective roofing solution. Here are four reasons why you should consider it for your commercial roofing systems.

  • Durability: TPO roofing systems are designed to withstand the rigors of the elements. They are impact-resistant and can withstand high winds and heavy rain. The roofs also have a high resistance to fire, making them an ideal choice for safety-conscious business owners.
  • Energy Efficiency: TPO roofs are highly reflective, which helps to keep your building cooler in the summer and warmer in the winter. This can help reduce your energy costs and make your building more comfortable for employees and customers.
  • Cost-Effectiveness: TPO roofs are a cost-effective roofing solution for commercial buildings. The roofs are long-lasting and require little maintenance, which can save you money in the long run.
  • 2:12 Roof Facet: The 2:12 roof facet is the perfect pitch for TPO roofs. This allows the roofs to shed water quickly and efficiently, keeping your building dry and protected from the elements.

TPO roofing systems are a great way to protect your commercial building. The roofs are durable, energy-efficient, and cost-effective, making them an ideal choice for any business owner.

How Long Does TPO Roofing Last?

TPO roofing is one of the most popular choices for commercial and industrial buildings, thanks to its durability and low maintenance requirements. But how long does TPO roofing last?

While the average lifespan of a TPO roof is 20-25 years, some roofs have been known to last much longer. Your TPO roof can last 30 years or more with proper care and maintenance.

Here are some tips to help you get the most out of your TPO roof:

  • Inspect your roof regularly. It’s important to catch any problems early so they can be repaired before they cause major damage. Be sure to check for loose seams, cracks, or holes in the membrane.
  • Keep your roof clean. Dirt, leaves, and other debris can clog drains and cause ponding, leading to the roof’s premature ageing.
  • Have your roof professionally cleaned every few years. This will remove any dirt or debris that has built up over time.
  • Make repairs promptly. Don’t wait to fix small problems because they can quickly turn into big ones.
  • Consider a TPO roof coating. A roof coating can extend the life of your roof by protecting it from UV rays and other elements.

By following these tips, you can help ensure that your TPO roof lasts many years.

How Much Does TPO Roofing Cost?

TPO roofing costs an average of $4-$14 per square foot, making it one of the most affordable roofing options on the market. TPO is a single-ply membrane made from thermoplastic polyolefin that is heat-welded together at the seams to create a watertight seal. This type of roofing is often used on commercial buildings because it is durable and easy to install.

It can also be installed over an existing roof, which makes it a great option for retrofitting projects. Compared to other roofing types, it is a pretty cost-effective solution. For example, EPDM (ethylene propylene diene monomer) roofs typically cost about $10-$17 per square foot. If you are looking for an affordable roofing option that is durable and easy to install, TPO may be the right choice for your project.

What Are The Benefits Of TPO Roofing?

TPO roofing systems offer several advantages over traditional roofing materials. The roofs are highly reflective, which can help to reduce energy costs by keeping your building cooler in the summer months. Also, they are also very durable and can withstand high winds and severe weather conditions. The perks include:

1. High Reflective Ability

A TPO roof’s surface is white, meaning it has a high level of reflectivity. This can help keep your building cooler in the summer by reflecting sunlight away from the surface. This can lead to lower energy costs as your air conditioning system won’t have to work as hard to keep the inside of your building cool.

2. Extreme Durability

TPO roofs are very durable and can withstand high winds and severe weather conditions. They are also resistant to tears and punctures, making them an ideal choice for areas that experience extreme weather conditions.

3. Cost-Effective in the Long Run

While the initial cost of a TPO roof may be higher than traditional roofing materials, they are designed to last for many years. This means you won’t have to replace your roof as often, saving you money in the long run.

4. Flexible Installation

TPO roofs are very flexible, making them easier to install than traditional roofing materials. This flexibility also allows them to expand and contract in response to temperature changes, which helps prevent cracks and leaks.

5. Wide Temperature Tolerance

TPO roofs can withstand a wide range of temperatures, from -40 degrees Fahrenheit to 160 degrees Fahrenheit. This makes them an ideal choice for both hot and cold climates.

6. Resistant to Chemicals, Fire, and UV Rays

TPO roofs are also resistant to chemicals, fire, and UV rays. Hence, an ideal choice for businesses that are looking for a roofing solution that will protect them from the elements.

Overall, they are an excellent choice for any business or building owner looking for a durable, energy-efficient, cost-effective roofing solution.

How to Choose a TPO Roof?

There are several factors to consider when choosing a TPO roof.

  • Thickness: TPO roofs are available in various thicknesses ranging from 30 to 80 mils. The thickness of the roof will determine its durability and resistance to punctures and tears.
  • Warranty: They come with various warranties, from 5 to 20 years. Choose a warranty that meets your needs and budget.
  • Colors: The roofs are available in a variety of colors, including white, tan, gray, and black. Choose a color that will complement the exterior of your home or business.
  • Weldability: TPO roofs can be welded together to create a watertight seal. This is an important feature to consider if you live in an area that experiences severe weather conditions.
  • Cost: The roofs are available at a variety of price points. Choose a roof that fits your budget and needs.

TPO Roof Installation

The installation process incorporates a hot air welding mechanism. It is a process that is commonly used in the roofing industry to weld two pieces of material together. This type of welding uses a hot air gun to heat up the two pieces of material, which are then pressed together to form a bond. Hot air welding is a quick and easy way to weld two pieces of material together, and it is also very strong.

If you are considering using hot air welding for your roofing project, be sure to consult with professional roofing contractors to ensure that it is the right choice for your project.


Is A TPO Roof Good?

TPO roofs are known for their durability and longevity. They can withstand extreme weather conditions and protect your home or business from water damage. Also, they are low maintenance and easy to clean.

Which Is Better TPO Or EPDM?

TPO roofs are more durable and longer-lasting than EPDM roofs. They are also more resistant to extreme weather conditions and provide better protection against water damage. However, EPDM roofs are easier to install and may be a better choice for some applications.

Can You Walk On A TPO Roof?

Yes, you can walk on a TPO roof without damaging it. However, you should avoid walking on the roof if it is wet or snowy as this could increase the risk of slipping and falling. Also, be sure that the roof has a proofing membrane to protect it from punctures.

Which Type Of Flat Roof Is Best?

There is no one “best” type of flat roofs. The best roof for your home or business will depend on your specific needs and preferences. However, TPO roofs are a good choice for many applications because they are durable, easy to maintain and provide excellent protection against water damage.

How Thick Should A TPO Roof Be?

TPO roofing membranes come in a variety of thicknesses, with the most common being 60 mils. 1 mil is equal to 0.001 inches, so a 60 mil membrane is actually 0.06 inches thick. TPO roofs are durable and can withstand a lot of wear and tear. They’re also easy to maintain and repair, making them a popular choice for many homeowners.

Is TPO Roof Glued Down?

No, TPO roofs are not glued down. Adherence is a key factor in the installation of TPO roofs. There are three main ways to adhere the membrane to the substrate: fully adhered, mechanically attached, or ballasted.

When a TPO roof is installed fully adhered, the membrane was glued to the substrate using a strong adhesive. It creates a chemical bond with the TPO. This method is considered to be the strongest and most durable way to install a TPO roof.

What Is The Longest Lasting Flat Roof?

There is no definitive answer to this question, as the longevity of a flat roof depends on many factors, such as the materials used, the quality of installation, and the climate in which it is located. However, TPO roofs are a good choice for many homeowners because they are durable, easy to maintain and provide excellent protection against water damage.

Can You Install TPO Over Plywood?

Yes, you can install TPO over plywood. TPO is a type of single-ply roofing membrane that is made from thermoplastic polyolefin. This material is heat weldable, which means that it can be easily installed over an existing roof without having to remove the old roofing material first.


TPO roofing is an energy-efficient and eco-friendly option for commercial and industrial buildings. It is durable, long-lasting, and can withstand extreme weather conditions.

It is also one of the most durable roofing materials on the market, with a 20-30 years. If you are looking for a new roofing system for your property, TPO roofing should definitely be at the top of your list.
