TPO roofing is a relatively inexpensive rubber roofing material that is most commonly used in commercial buildings. TPO stands for thermoplastic polyolefin; It is mainly made from recycled rubber and is sold in rolls that are held together by seams that are “glued” together by heat.

If you are considering using TPO or other types of rubber roofs for your home, it is important to know that this type of roof is best for flat roofs or those with a very low pitch. While this type of shelter can be very inexpensive, it has a unique list of advantages and disadvantages. Here we will discuss these and much more, including typical TPO roofing costs and TPO roofing material prices.

A NOTICE: The first half of 2021 saw an unprecedented labor shortage as a side effect of the COVID-19 pandemic. In connection with this, the demand for materials and construction jobs has skyrocketed. As a result, material prices may be higher than indicated in this article and lead times for both labor and materials may be longer than usual.

How much does a TPO roofing cost?

Although it is sold in rolls, TPO roofs are often calculated by squares, like most types of roofs. A square is 100 square feet of roofing material and your TPO roof estimate can be expressed in squares. Experts note that one square meter of TPO roofing is $ 3.50 to $ 14.00. That would mean a square of TPO in the price of $ 350 to $ 1,400. There is a huge fluctuation in price that reflects the different thickness options available for TPO roofs.

Is TPO Roofing Right for Your Job?

Aside from the relatively low cost per square meter of TPO roofing, there are several things to consider before deciding on this type of roofing. Here are some pros and cons of TPO roofs:


  • Reflective material lowers energy costs
  • Easy to install, which can result in lower TPO installation costs
  • Very low maintenance
  • Environmentally friendly as it is made from recycled materials
  • Easy


  • Not the most attractive type of shelter
  • Must be installed in dry conditions (due to the heat adhesion process for the seams)
  • The material quality varies greatly between manufacturers, which leads to fluctuations in TPO roofing material prices

TPO roofing material prices

Installing a TPO roof requires more than just the roofing material. You will also need to purchase insulation that will be installed directly under the roofing. The average cost of insulation ranges from $ 1.50 to $ 3.50 per square meter. In addition, you will likely need a facing to prevent water from getting under the roofing and a fastening system. We will discuss each of these TPO roofing material prices below.

TPO insulation

In some cases, the cost of insulation can be even higher than the cost of TPO roofing, depending on the material and thickness you choose. In most cases, however, the insulation for rubber roofs wraps around $ 1.50 to $ 3.50 per square foot. The insulation acts as a protective underlay for the TPO roofing and also helps regulate the temperature of the house or building.

TPO flashes

You will need to add facing along seams and corners to prevent water from entering the interior of the building. The number and type of connection plates required depends entirely on the roof you want to cover, whether there are peaks or dormers, a chimney or something else attached to the roof. Typical costs for flashing pieces range between 5 and 50 dollars.

TPO fastening system

Like any roof, your TPO roofing will need to be attached to the top of your home or building. There are three methods for doing this, and the price varies for each:

  • Ballasted fastening: Weights the roof with stones or cobblestones
  • Fixed roof: Uses screws to attach the rubber roof to the base
  • Attached roof: Uses glue to attach the rubber roof to the base

Below we’ve included a table that breaks down the TPO roof cost for each type of fixture.

Cost of installing TPO roofs

It’s not too difficult to install TPO roofs. It is estimated that a roofer would be between $ 75 and $ 90 an hour for this type of work. Of course, factors such as removing old roofing can increase the time required and thus the TPO installation costs. You can expect between $ 1 and $ 2 per square foot for a simple roof extension. Other factors that can potentially increase TPO installation costs are the climate and whether you have hard-to-reach areas on your roof.

Frequently asked questions (FAQs)

Should I try to build a rubber roof myself?

When it comes to roofing, installing a rubber roof is one of the easier ways to do it yourself. But that doesn’t mean anyone can jump on their roof and install rubber roofs because there are some important considerations. First of all, it is imperative that you install the TPO roofs on a flat, even surface. This means that you need to inspect your current roofing first and look out for bumps like damaged sub-roofing or wavy shingles.

Another thing to consider is the insulation required before a rubber canopy can be installed. Finally, the seams of the rubber roofs are melted together with a heat gun. If you don’t own or have experience with these types of tools, it may be better for a professional to install your rubber roof.

How does TPO roof reduce energy costs?

Energy saving is one of the greatest advantages of TPO roofs. Since the material is white and the surface is smooth, the TPO roof is highly reflective. This means that when the sun’s UV rays hit the roof, the heat is deflected away from the building and not absorbed. This will help lower your climate costs. There are other types of rubber roofs that, with their dark colors, are used to absorb the heat, such as EPDM roofs.
