What Is A TPO Roof?

TPO, short for thermoplastic polyolefin, is a single-ply roofing membrane composed of polypropylene and ethylene-propylene rubber. It is one of the most popular roofing materials in the U.S. due to its durability, energy efficiency, and affordability. TPO roofing membranes are available in a wide range of colors, such as white, gray, or tan, and are often preferred for their reflective properties that can help reduce cooling costs.

Benefits of TPO Roofing Systems

TPO roofing systems are among the top choices for commercial buildings. Here are a few benefits of a TPO roof that make it a good and durable option.

Energy Efficiency

TPO roofing membranes have energy-efficient properties. The light-colored surface reflects a significant amount of solar radiation, which can help lower your building’s cooling costs during the hot summer months. In regions with consistently high temperatures, TPO roofs can contribute to a more comfortable living environment while saving you money on utility bills. 

Durability

TPO roofing materials are designed to withstand harsh weather conditions, including extreme temperatures, wind, and UV radiation. They are resistant to ozone, chemical exposure, and fire, making them a long-lasting and reliable option. With correct installation and ongoing maintenance, a TPO roof can last for 25 years or more.

Low Maintenance

TPO roofing systems require minimal maintenance compared to other roofing materials. The seamless nature of the membrane reduces the risk of leaks, and its resistance to algae, mold, and mildew growth further minimizes the need for frequent cleaning or repairs. However, you may need to perform regular inspections to enhance the lifespan of your TPO roof.

Environmentally Friendly

TPO roofing membranes are recyclable at the end of their lifespan and most types do not contain any kind of chlorine or plasticizers, making them an eco-friendly choice. Additionally, the energy-efficient properties of TPO roofing systems can reduce your building’s carbon footprint by decreasing the amount of energy needed for cooling.

Easy Installation

TPO roofs are lightweight, and they can be installed easily and quickly. This makes TPO roofing systems a convenient choice for both new construction and re-roofing projects, minimizing disruptions and ensuring a smoother installation process with reduced labor costs.

Drawbacks of a TPO Roofing Membrane

There are certain drawbacks of a TPO roof that you’ll need to consider before installing one on your building.

May Shrink In Extremely High Temperature

TPO roofs are durable in harsh climatic conditions, however, if exposed to extremely high temperatures and direct sunlight, they can become brittle or shrink over time. 

May Require Regular Repairs

TPO roofing problems may include punctures, leaks at seams or joints, or bubbling of the membrane. Professional installation and maintenance can lower the chance of problems with your TPO roof.

Limited Lifespan

TPO roofs come with a limited lifespan and last for 25-30 years. However, if maintained properly the lifespan can be increased.

Are TPO Roofing Systems Only for Commercial Buildings?

While TPO is widely used for commercial and industrial buildings, it is also an excellent choice for residential properties. TPO roofing systems are suitable for various types of roofs, including flat and low-slope. They can be installed for new construction and re-roofing projects, offering both home and business owners a durable and cost-effective solution.

Maintenance and Installation Tips

Proper installation and upkeep play an essential role in maintaining the durability and performance of your TPO roofing system. Here are a few tips to consider:

Installation

1. Choose a reputable and experienced roofing contractor who specializes in TPO roofing installations. This lowers the chance of mistakes during the installation process.

2. Make sure that the roof deck is clean, dry, and free of any debris before installation. It’s crucial to ensure that the surface is smooth and level, as any irregularities or protrusions can potentially puncture or damage the TPO membrane.

3. Follow the manufacturer’s instructions for proper seaming and fastening techniques. Adhere to the recommended overlap and heat-welding temperatures to create durable, watertight seams. Improper seaming is a common cause of leaks in TPO roofing systems.

4. Consider installing walkway pads in high-traffic areas to protect the membrane from potential damage. These provide an additional layer of protection against punctures, tears, and excessive wear caused by foot traffic or maintenance equipment.

Maintenance

1. Conduct regular inspections (at least twice a year) to check for any signs of damage, debris, or potential issues. These inspections should be thorough, covering the entire surface area, seams, flashing, and penetrations, which can prevent more extensive and costly repairs.

2. Clean the roof regularly by removing any dirt, dust, leaves, mold buildup, or other debris that may accumulate. Debris can trap moisture, promote algae growth, and potentially cause physical damage to the membrane if left unchecked for an extended period.

3. Avoid placing heavy objects on the roof that could puncture or tear the membrane. TPO membranes are durable but can still be damaged by sharp or heavy objects, so exercise caution when accessing the roof for maintenance or repairs.

4. Address any repairs promptly to prevent further damage and extend the life of your TPO roofing system. Even small punctures or tears can quickly lead to more extensive leaks and water damage if not addressed in a timely manner, compromising the integrity of the entire roofing system.

Estimated Cost of a TPO Roofing System

The cost of a TPO roofing system will vary by several factors, including the size of your roof, the difficulty of installation, and the location of your property. 

On average, TPO roofs typically cost between $5.50 and $8.75 per square foot, including labor and material costs.
