TPO Roofing: What You Need to Know

Are you thinking about having TPO roofing installed? TPO is a single-ply thermoplastic polyolefin roof membrane highly resistant to UV, ozone, infrared, and chemical exposure. This single-ply roof membrane comprises sheets of rubber and another synthetic material glued together to create one huge sheet. These sheets range in width from 10 to 20 feet. 

TPO roofing, which first appeared in the early 1980s, has become one of the world’s fastest-growing roofing systems, not only in America, particularly when increasing numbers of homeowners want a simple and contemporary appearance.

The inexpensive cost and long life expectancy of 22 to 30 years, greatly beyond the usual 15-year lifetime of conventional roofing systems, increased its popularity. Over 22 to 30 years, seams may separate, flashings can fail, the membrane can get perforated, and cracks might form, potentially causing a roof leak. 

Owners and landlords should be concerned about the potential damage to the roof. They should contact a reputable roofing company to repair the roof if water has started to enter the building or dwelling.

You may require a commercial roofing professional to complete a free roofing inspection if there is any damage.

He will examine for and notify you of the following items:

  • The TPO Roof’s Age
  • Roof Condition
  • Where Your Roof Has Cracked
  • Where the Water Enters
  • Repair Costs

Insulation Options for TPO Roof Installation

Today we’ll review the three different kinds of insulation and see which is best for your roof.

The three most popular forms of insulation in a TPO Roofing System are:

  1. Polyisocyanurate (Polyiso)
  2. Polystyrene (EPS)
  3. Extruded Polystyrene (XPS)

Polyisocyanurate (Polyiso)

It is an insulating board with a face of glass fiber-reinforced cellulosic felt connected to an isocyanurate foam core. This insulation has the following advantages:

  • Sized Just Right
  • Excellent Thermal Efficiency
  • Fire Resistance
  • Versatility
  • Comply With Building Code Requirements.
  • LEED Credits
  • Environmental Friendliness
  • Compatibility
  • Outstanding Service Temperature
  • Superior Dimensional Stability

Expanded Polystyrene

White plastic sheet material created or generated from solid polystyrene particles. This includes styrene (which helps to produce the cellular structure) and pentane (used as a blowing agent)

Its inclusion has the following advantages:

  • Low Thermal Conductivity
  • High Mechanical Compressive Strength
  • Mechanical Compressive Strength Prevention
  • Dimensional Consistency
  • Lightness
  • Economic Solution
  • Cold Resistant
  • Fireproof

Extruded Polystyrene

Roof sheets are made by an extrusion process that combines plastic resin and other components. As this foam cools and expands, it takes on its final form.

There are the following advantages of adopting this inclusion:

  • No Leaks
  • Reduced Heating and Cooling Expenses
  • Endurance
  • Versatility
  • Environment Friendly

Do You Need To Repair a TPO Roof?

TPO roofs have a long lifespan, lasting more than 15-20 years with little care. But, after this term has expired, the homeowner or landlord must consider contacting a roof repair firm to rectify any damages or repairs and, in some instances, full replacements. The first clue that your TPO roof needs maintenance and repair is when it begins to leak for the first time.

Last, you must do a roofing inspection.

After the examination, we will provide an estimated repair cost and the materials needed to finish the job. The following criteria will determine all repairs and material costs:

  • Roof dimensions and area: Cracks, bend, breaks, leakage, and other damage to the roof must be fixed. And the cost is determined by the size and area of the roof. The greater the size of the roof, the more dents and fractures there will be.
  • Materials required: Polyisocyanurate (Polyiso), Expanded Polystyrene (EPS), and Extruded Polystyrene (XPS) determine the amount of money necessary for the material. Polyisocyanurate is the most widely used and widely available material for TPO roofing and repair.
  • Skilled work: Eventually, the job will be done by qualified roofers. The number of hours of labor and days required to complete the job will entirely depend on the extent of the damage and the area of your damaged roof.
  • Existing roof condition: The typical individual will find several dings and fissures difficult to detect. The roof repair inspector will be able to detect any concealed roof dents, cracks, or flaws that might lead to leaks within the next year or two.
  • Warranty type: Several materials and roof repair providers offer varying guarantees on roof repair services. This element also influences the cost.

  • The next stage is to measure the specifications of the roof correctly. The TPO roof system is then affixed to the roof using specialized and special equipment. The experienced team will utilize welding equipment and a fastening heat plate to repair the TPO roof system.

TPO membranes come in a variety of thicknesses. Membranes range in thickness from 40 to 80 mils and come in various grades. The quality is determined by the manufacturer from whom you get it.

They are utilized to produce watertight seams that protect the roofs from penetrations and seal the roof edges. If the TPO roofing system is correctly built, it will aid in forming a water or snow barrier. It will assist you in keeping your house, business, or any other structure dry.

Therefore, these are some of the expert methods for How to Install TPO Roofing. Integrity Roofing can assist you with installation if you want expert assistance.

What Is the Composition of a TPO Roofing System?

The TPO roofing membrane is made of a particular substance that helps you keep your property dry.


TPO roofs are composed of a single-ply membrane. This single-ply membrane has three layers that are joined to form one TPO membrane. TPO membranes comprise polypropylene, which is the fundamental ingredient of the TPO roofing system and ensures the roofing membrane’s strength and longevity. For resistance, another PP chemical is applied.

EPDM, EPR, or Thermoplastics

TPO roofing membranes include EPDM, EPR, or thermoplastics to improve the overall efficacy of the roofing system. There is also the potential for additional chemicals like carbon, talc, or fiberglass.

Antioxidants and Lubricants

The membranes also include colors, antioxidants, and lubricants to improve the TPO membrane’s function. Other chemicals are added to absorb UV radiation.

Before attempting to find out How to Install TPO Roofing, it is critical to understand the material utilized. Integrity Roofing can provide you with high-quality TPO roofing installation. You can rely on us to provide high-quality outcomes.

TPO Roofing System Layers

As previously stated, the TPO roof system is composed of three layers.

  1. The Outermost Layer
  2. The Third Layer
  3. The Foundation Layer

The Outermost Layer

UV absorbers make up the top layer of the TPO roofing system.

The Third Layer

The central layer is made of polyester, which adds strength to the construction and increases resistance.

The Foundation Layer

The TPO membrane’s base layer is for flexibility and adherence.

What Distinguishes the TPO Roof From Others?

Which Rubber Roofing Material Is Better_ TPO or EPDM

If you plan to buy a new roof, you may wonder if TPO or EPDM is the better choice. TPO and EPDM are both rubber roofing materials. Thus they have many similarities. Yet, there are some significant variances. This blog article will compare TPO versus EPDM and assist you in determining which material is appropriate for your requirements.

What Is TPO Roofing?

TPO roofing is a single-ply thermoplastic polyolefin membrane. TPO is a popular commercial roofing material because it is heat-resistant and reflective, which helps keep buildings cool in hot areas. TPO is also resistant to UV rays and simple to install. TPO is a newer roofing material that has grown in popularity recently. One of the reasons TPO is so popular is its durability. TPO roofs have a lifetime of up to 20 years, which is much greater than the lifespan of most conventional roofing materials.

What Is EPDM Roofing?

EPDM roofing is a single-ply rubber membrane composed of Ethylene Propylene Diene Monomer. Since it is long-lasting and simple to install, it is a popular option for commercial and residential roofs. With regular care, EPDM may endure for up to 30 years. EPDM roofs are less prone to rips and punctures than TPO roofs but are not heat resistant. If you live in a hot region, TPO may be a better alternative than EPDM.

TPO Vs EPDM: Pros And Cons

TPO Pros:

  1. Heat resistant: Since it is heat-resistant and reflective, TPO is a popular option for commercial roofing in hot areas.
  2. TPO is also UV-resistant, which means it will not fade in the sun over time.
  3. Simpler installation: TPO is a popular option among contractors since it is simple to install.
  4. Reflective: The reflective surface of TPO aids in keeping buildings cool in hot weather.

TPO Cons:

  1. TPO is susceptible to punctures.
  2. Price: TPO is often more costly than other types of roofing materials.
  3. Durability: TPO has a lower life expectancy than EPDM (around 15 years). TPO may not be as long-lasting as other roofing materials.

EPDM Pros:

  1. Durable: EPDM is one of the most long-lasting roofing materials on the market. It has a lifespan of up to 30 years.
  2. Waterproof: EPDM is completely waterproof, making it an excellent solution for leaky roofs.

EPDM Cons:

  1. Price: EPDM is often more costly than TPO or other roofing materials.
  2. Installation: EPDM may be difficult to install, so leaving it to the pros is better.
  3. Reflective qualities: EPDM, unlike TPO, lacks reflective qualities, allowing it to absorb heat in hot areas.

When determining which roofing material is best for you, consider the advantages and downsides of each. TPO and EPDM are common commercial roof materials but have distinct benefits and downsides. TPO is more heat-resistant and simpler to install than EPDM but less durable. While EPDM is more durable, it is also more costly. Finally, it boils down to your demands and budget.

Which Rubber Roofing Material Should You Use?

TPO and EPDM have advantages, so it all comes down to what is essential to you. TPO is preferable if you require a roof that can tolerate extreme temperatures. But, if durability is your primary issue, EPDM may be a better option. Whichever material you pick, ensure it is installed correctly by a competent contractor. Don’t take risks with one of your home’s most essential elements!


Although both TPO and EPDM have advantages and disadvantages, TPO is often preferable for roofing applications. Working with a knowledgeable contractor to assist you in selecting which material is ideal for your requirements is vital.
