Advantages And Disadvantages Of TPO Roofing

TPO (thermoplastic olefin) is an alternative type of roofing material that is made out of layers of plastics and rubbers to seal your roof from the weather, forming a roofing membrane on your home. However, because of its unique material qualities and method of construction, TPO roofing provides a distinctive set of advantages and disadvantages to your home. Understanding what TPO roofs can offer can make it easier for you to choose whether or not to have a TPO roof installed on your home.

Advantages of TPO Roofing

Durability: TPO roofing is an extremely durable roofing material that is resistant to mold growth, will not rust, and can withstand tearing and puncturing over an extended period of time. Some variants of TPO roofing come with reinforcing layers installed with them (at an extra cost) which help increase the amount of wear and tear your roof can withstand.

Ease of Installation: Unlike traditional asphalt shingles, TPO roofing comes in large sheets. The benefits of this are twofold: firstly, the installation process is expedited, helping to reduce initial costs as your roof can be laid down quicker. Secondly, there are fewer seams on your roof, which helps to reduce the chances of a leak developing and the overall amount of maintenance that you will have to perform.

Energy Efficiency: The top layer of TPO roofing is white, which means that TPO roofs are cool roofs: they will reflect sunlight away from your home and prevent heat from transferring into your house through the roof. This will help maintain the comfort levels within your home and keep your energy bills low during the summer months by reducing the amount of strain placed upon your air conditioner while still keeping the temperature manageable.

Disadvantages of TPO Roofing

Heat Resistance: TPO roofing is susceptible to increased wear and damage when exposed to heavy amounts of sunlight and heat. This means that TPO roofing may not be the most ideal choice for homes in extremely warm climates, as your roof may break down at an accelerated rate and will need to be replaced or repaired at an increased rate, which can become a significant expense over time.

Longevity: TPO roofing is a newer roofing material, and has not been around for decades like asphalt shingles and other traditional options have been. This means that the actual lifespan of TPO roofing is yet unknown, and your roof may fail because of an as of yet undiscovered reason. Consult with a roofing contractor to decide if TPO roofing is the right fit for your home. For more information, visit sites like
