What Is TPO Roofing? - Everything You Need To Know

TPO roofing is a relatively new roofing material, but it has been gaining popularity in recent times. It is an excellent choice for roofs with high loads, such as those found in commercial and industrial buildings.

TPO roofing is more durable than traditional roofs. This type of roofing is also resistant to water damage and impact damage. Additionally, TPO roofs are ideal for areas exposed to weather conditions, whether they be extreme temperatures or high winds.

Whether you’re looking to use TPO roofing in your home or office or if you want to install it on your vehicle, this guide will help you make the right decision and get the job done right.

What is TPO Roofing?

TPO roofing is a heat-reflective, single-ply, and energy-efficient roofing material used on residential and commercial flat roofs. It's a blend of polypropylene, and ethylene-propylene rubber polymerized together, and it comes in 45 mils or 60 mils thickness.

TPO is a more affordable alternative to PVC roofing and is touted as a more energy-efficient alternative to EPDM and PVC. TPO is ideal for low-slope dormers, garages, or covered patios because it keeps the room below cooler.

But its white membrane gets dirty quickly, so you should regularly inspect it for signs of wear and tear. The TPO roofing system is composed of various accessories like an anti-oxidation membrane, a fireproof layer, and a non-woven fabric layer.

History of TPO Roofing

TPO roofing was developed in the early 1990s as an alternative to traditional roofing materials like asphalt and BUR (built-up roofing). It was designed to be more energy savings and provide superior durability.

Since its introduction, TPO roofing has become increasingly popular due to its many benefits, including its affordability and easy installation process.

Additionally, TPO roofing offers excellent waterproofing and UV protection, making it an ideal choice for many commercial and residential applications.

Types of TPO Roofing

TPO Roofing

Reinforced TPO

Reinforced TPO is a type of thermoplastic polyolefin that is reinforced with fiberglass for additional strength and durability. It is often used for roofing and other outdoor applications where extra strength and durability are needed.

The fiberglass reinforcement helps make reinforced TPO more resistant to tearing and puncturing than regular TPO, making it a good choice for applications where the material needs to withstand more wear and tear.

It is also more resistant to UV degradation and can last longer than regular TPO in outdoor applications.

Non-reinforced TPO

Non-reinforced TPO (thermoplastic olefin) is a thermoplastic material that is used in roofing membranes. It is a single-layer, flexible material that is made up of polypropylene and ethylene-propylene rubber.

Non-reinforced TPO does not have any fiber reinforcement, which makes it less durable than reinforced TPO. It is also more prone to ultraviolet (UV) degradation, tearing, and puncturing.

Non-reinforced TPO is best suited for low-slope roof applications, as it is not designed to withstand the same amount of weight as reinforced TPO. It is also less expensive than reinforced TPO, making it a good choice for budget-conscious homeowners.

Fleece-backed TPO

Fleece-backed TPO is a type of TPO roofing material used for multiple-ply roofs. It provides increased durability and superior cut and puncture resistance.

TPO AC Fleece is a special type of TPO roofing that has enhanced protection in multiple-ply roofs. TPO sheets can be mechanically attached, adhered, or ballasted and come in different thicknesses and colors.

GenFlex TPO offers multiple options, including EZ TPO Plus for greater puncture resistance and GenFlex EZFlex TPO Peel & Stick for uniform adhesion.

This versatile roofing material can be used in many types of roofs, including low-slope roofs composed of polypropylene and ethylene-propylene rubber.

Self-adhered TPO

Self-adhered TPO is a type of thermoplastic polyolefin (TPO) membrane that is applied to a roof deck without the use of adhesives. Self-adhered TPO membranes are typically composed of a white, reflective top layer and a black, non-reflective bottom layer.

The two layers are adhered together using a layer of pressure-sensitive adhesive (PSA) between them. The membrane is then rolled out onto the roof deck, and the PSA is activated by pressure from a roller.

Self-adhered TPO membranes are used as a highly effective waterproofing system for flat or low-slope roofs. They are often used in residential and commercial roofing applications, as well as in areas that are susceptible to extreme weather conditions.

Mechanically attached TPO

Mechanically attached TPO roofing systems are a type of roofing system consisting of a TPO membrane, which is secured to the roof deck or insulation board by mechanical fasteners, such as screws, plates, and washers.

This type of system is considered to be a moderately priced roofing solution that offers a number of benefits, including long-term durability, improved energy efficiency, and resistance to UV radiation.

The TPO membrane can be installed quickly and easily, allowing for a timely roof installation.

How much does TPO Roofing cost?

The cost of TPO roofing can vary depending on a number of factors such as the size and complexity of the roof, location, and contractor or supplier you choose to work with.

On average, the cost of TPO roofing installation can range from $6 to $12 per square foot, including materials and labor. For a typical single-story home with a roof area of around 2,000 square feet, this would translate to a total cost of $12,000 to $24,000.
