What is TPO Roofing?

Thermoplastic Olefin (TPO) roofing is a single-ply roofing membrane used primarily on commercial and industrial buildings. TPO is made from a blend of polypropylene and ethylene-propylene rubber, providing a durable and cost-effective roofing solution. The membrane is typically installed in large sheets and heat-welded at the seams to create a strong, watertight barrier on your building's roof.

The Benefits of a TPO Roof System

TPO roofing offers numerous advantages for residential and commercial properties, including:

Lower Materials and Labor Costs

TPO roofing materials are generally more cost-effective than other commercial roofing options. Additionally, the installation process is relatively straightforward, which can result in lower labor costs. Special and expensive walk-behind welding bots provide efficient and accurate welding results.

Greater Energy Efficiency

TPO roofing systems are highly reflective, helping to reduce heat absorption and lower cooling costs during the warmer months. This energy efficiency can significantly save your building's energy bills.

Strong and Flexible

TPO roofing membranes are highly resistant to punctures, tears, and impact damage. They are also flexible, allowing for expansion and contraction with temperature changes without compromising their integrity.

Wider and Lighter

TPO roofing membranes are available in wider sheets than many other roofing materials, which means fewer seams and a lower likelihood of leaks. The material is also lightweight, reducing the stress on your building's structure. Often an older roof with a solid deck can incorporate a TPO Overlay and save on tear off costs and dump fees.

PVC Membrane Roofing Systems

In addition to TPO roofing, Rainblock Roofing LLC can also offer PVC membrane roofing systems for residential and commercial properties, providing another durable and energy-efficient option for your building. They are a bit more costly but in cases where PVC has already been used then PVC is the only material that can weld to it.

Frequently Asked Questions

The average cost for a TPO roof varies depending on factors such as the size of the roof, complexity of flashing protrusions, labor costs, and geographical location. Generally, TPO roofing can cost anywhere between $6 and $9 per square foot installed.

It is generally safe to walk on a TPO roof, as the material is designed to be durable and resistant to punctures. We commonly use a 60 mil vs 40 mli for durability. It’s also common to lay a second layer service mat or runway if desired. However, it is always best to exercise caution and wear soft-soled shoes when walking on any roof to minimize the risk of damage.

Recoating a TPO roof is not typically recommended, as the material is designed to be durable and long-lasting without the need for additional coatings. Any repair can mean simply welding a patch over the puncture or resealing a missed spot. However, if your TPO roof has experienced significant damage or is nearing the end of its lifespan, it may be necessary to consider recoating or replacing the membrane.

TPO roofs that are anchored with screws and plates can have a small amount of lift or wrinkle. These often will disappear after a cold weather event causes it to tighten up a bit. It doesn’t restretch in warm weather and puddling won’t be a problem if installed correctly. Bubbles or blisters in a TPO roof may indicate improper installation or trapped moisture between the membrane and the substrate. If you notice bubbles in your TPO roof, it is essential to consult with a professional roofing contractor to assess and address the issue.

Flex Seal is not recommended for use on TPO roofing materials, as it may not adhere properly or could damage the membrane. There is special caulking available, but it is always best to consult with a professional roofing contractor to determine the appropriate repair method for your TPO roof.

A TPO roof typically requires an underlayment vapor barrier, an insulation layer and a compatible substrate, such as high-density cover board or plywood, to provide a smooth, stable surface for the TPO membrane to adhere to.

The best sealant for a TPO roof is a TPO-specific seam primer and seam tape or a TPO-compatible, high-quality adhesive. It is essential to use materials that are specifically designed for TPO roofing to ensure a proper bond and long-lasting performance.

Both light gray and white TPO roofing materials have their advantages. They are highly reflective and can provide better energy efficiency, while bronze & dark gray TPO may offer improved aesthetics for some building designs. However, the added die will increase the cost of the material. Ultimately, the choice depends on your specific needs and preferences.

TPO roofing materials are inherently resistant to UV radiation, and most TPO membranes are designed with UV inhibitors to further enhance their durability and longevity. As a result, TPO roofs generally do not require additional UV protection.

The most durable roof waterproofing depends on the specific requirements of your building and environment. TPO and PVC roofing systems are both popular choices for their durability, waterproofing capabilities, and resistance to UV radiation. It is essential to consult with a professional roofing contractor to determine the best option for your needs.
