TPO roofing is a relatively inexpensive rubber roofing material most commonly used on commercial buildings. TPO stands for Thermoplastic Polyolefin; it’s made primarily from recycled rubber and sold in rolls held together by seams that are “glued” together using heat.

If you are considering using TPO or other types of rubber roofing on your home, it is important to know that this type of roof is best suited for flat or very low slope roofs. While this type of roofing can be very cost effective, it has a unique list of pros and cons. Here we discuss these and many more, including typical TPO roofing costs and TPO roofing material prices.

NOTE: In the first half of 2021, there will be an unprecedented labor shortage as a side effect of the COVID-19 pandemic. In combination with this, the demand for materials and construction work has increased enormously. As a result, material prices may be higher than those listed in this article and lead times may be longer than normal for both labor and materials.

How much does TPO roofing cost?

Although sold in rolls, TPO roofing is often priced by the square, like most types of roofing. A square is 100 square feet of roofing material and your estimate of TPO roofing costs may be in squares. Experts find that a square foot of TPO roofing can range from: $3.50 to $14.00. That would mean that a square of TPO could range in price from $350 to $1,400. There is a wide variation in price reflecting the different thickness options available for TPO roofing.

Is TPO Roofing suitable for your work?

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

Pros

  • Reflective material lowers energy costs
  • Easy to install, which can lead to lower TPO installation costs
  • Very little maintenance required
  • Environmentally friendly, as it is made from recycled materials
  • lightweight

cons

  • Not the most attractive type of roofing material
  • Must be installed in dry conditions (due to the heat adhesion process for the seams)
  • Material quality varies drastically between manufacturers, leading to variability in the prices of TPO roofing materials

TPO Roofing Material Prices

Installing a TPO roof requires more than just the roofing material. You also need to buy insulation, which is installed directly under the roofing material. The average cost of the insulation ranges from $1.50 to $3.50 per square foot. In addition, you will probably need a gutter, which prevents water from leaking under the roof covering, and a fixing system. We will discuss each of these TPO roofing material prices below.

TPO insulation

In some cases, the cost of insulation can even exceed the TPO roofing cost, depending on the material and thickness you choose. However, in most cases, rubber roofing insulation is walking around $1.50 to $3.50 per square foot. The insulation acts as a protective underlayer for the TPO roofing and also helps regulate the temperature in the house or building.

TPO flashes

You should add flashing along seams and corners to prevent water from leaking into the interior of the building. The amount and type of gutter you need will depend entirely on the roof you want covered, whether it has peaks or dormers, a chimney, or something else attached to the roof. Typical costs for flashing pieces are between $5 and $50.

TPO fastening system

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

  • Ballasted attachment: Uses bricks or pavers to weight the roof
  • Fastened roof: Uses screws to attach the rubber roof to the subfloor
  • Attached roof: Uses glue to attach the rubber roof to the subfloor

Below we have included a table of the TPO roofing costs for each type of fixing.

Cost to Install TPO Roofing

It is not too difficult to install TPO roofing. It is estimated that a roofer between the $75 and $90 per hour for this kind of work. Of course, factors such as removing old roofing material can extend the time required and thus TPO installation costs. You can expect to pay between $1 and $2 per square foot for a simple roof removal job. Other factors that can potentially increase TPO installation costs include climate and whether you have hard-to-reach areas on your roof.

Frequently Asked Questions (FAQs)

Should I try to make a rubber roof?

As far as roofing goes, installing a rubber roof is one of the easier types to make yourself. But that doesn’t mean anyone can just jump on their roof and install rubber roofing, because there are some important considerations. First, it is imperative that you install TPO roofing on a flat, level surface. That means inspecting your current roofing first and taking care of any unevenness, such as damaged underroofs or curled clapboards.

Another thing to keep in mind is the insulation needed before rubber roofing can be installed. Finally, the seams of rubber roofing are fused together using a heat gun. If you do not have one or are not experienced in using this type of tool, it may be better for a professional to do your rubber roof installation.

How does TPO roofing reduce energy costs?

Energy saving is one of the biggest benefits of TPO roofing. Since the material is white and the surface is smooth, TPO roofing is highly reflective. This means that when the sun’s UV rays hit the roof, the heat is conducted away from the building rather than absorbed by it. This helps reduce your A/C costs. There are other types of rubber roofing that, with their dark colors, serve to absorb the heat, such as EPDM roofing.
