A TPO roof can have a lifespan of up to 30 years if it is properly maintained. Typically, the expected lifespan of a TPO roof is between 15 and 20 years. If you want to know how long a TPO roof will last on your building, you should know that its lifespan depends on several factors.
There are, however, some steps you can take to enhance its durability.
This article explains the longevity of TPO roofing and how long it will last in different locations and on various buildings. We’ll also share some essential tips to help you make sure your TPO roof lasts as long as possible.
How Long Do TPO Roofs Last?
On average, TPO roofing membranes last for 20 years with proper installation and maintenance. This is when your building is located in an area with mild weather conditions. In places with extreme temperatures and frequent storms, TPO membranes only last around 10 years. But if your town has pleasant weather all year round, this membrane can last as long as 30 years.
Top manufacturers have developed sturdy and durable TPO membranes that are designed to withstand harsh weather conditions and still last for 25 years. For example, GAF’s TPO roofing systems are currently leading the market with their 30-year guarantee and a 25-year limited warranty.
Factors Affecting The Lifespan Of TPO Roofs Membranes
TPO roofs are durable and resistant to many environmental elements, but their longevity is influenced by various factors. Understanding these factors can help you make informed decisions about your TPO roof installation and its maintenance. Let’s look at the key factors that impact the lifespan of a TPO roof.
When it comes to roofing, proper installation is crucial for any material to last long, and the same goes for TPO membranes. It is typically installed using one of two methods: mechanically attached or fully adhered. If the membrane is not installed correctly, or the seams are not welded properly, the roof can be susceptible to leaks and other problems, which shorten its lifespan. It’s essential to work with a professional roofing contractor with experience in TPO installation to ensure that the roof is installed correctly.
Roof Slope and Drainage
A proper slope and drainage system are essential for all types of roofing, including TPO. It should ideally be installed at a 1/4th inch per 12-inch roof slope. TPO roofing also requires proper flashing and edge detailing to ensure that water is directed away from the roof and does not seep underneath the membrane, or pool on top of it. Correct installation is a direct assessment of how long a TPO roof will last on your building.
A TPO roofing membrane is designed to withstand rain, hail, snow, UV rays, and temperature fluctuations. However, if a TPO roof is installed in an area with high levels of UV radiation, the membrane can begin to break down and degrade more quickly. Additionally, extreme temperature fluctuations can cause the membrane to expand and contract, which eventually causes damage. Proper insulation and reflective coatings can help protect TPO roofs from these environmental factors and extend their lifespan.
Maintenance and Upkeep
Regular maintenance is essential for all types of roofing, and TPO roofing is no exception. Routine inspections can detect minor issues before they become significant problems, such as punctures, tears, or seam separations. Prompt repairs can prevent further damage and prolong the lifespan of the roof. Neglecting regular maintenance can cause minor problems to escalate, leading to more extensive damage, which can shorten the lifespan of TPO roofs.
If you have a TPO roof and you suspect some damage, let’s discuss the common signs that indicate a TPO roof needs a professional inspection or replacement.
Signs Of TPO Roof Deterioration
Even with its impressive features, a TPO roofing membrane is not invincible and can deteriorate over time. It’s essential to be aware of the signs of TPO roof deterioration to prevent more significant issues down the road.
Here are some of the most common signs of TPO roof deterioration to watch out for:
If you notice cracks, punctures, tears, or blisters on your TPO roof, it’s time to take action. These issues can worsen over time and eventually lead to leaks or other significant problems. Delaying repairs is one of the main reasons why the lifespan of TPO roofing membranes gets reduced.
If you notice wet or dark stains on the ceiling, it means water has passed through the roof, causing leaks. This can occur due to punctures, tears, seam failures, or other forms of damage to the roofing membrane. If left unaddressed, water can seep into the roof deck and inside your building, electrical wiring, walls, and other areas.
While TPO roofing is designed to resist UV damage, exposure to UV rays over time can cause the membrane to degrade and become brittle. This can lead to cracks and other damage, reducing the effectiveness of your roof and shortening its lifespan. UV damage is marked by creases or blisters on the roofing membrane.
Reduced Energy Efficiency
As the TPO membrane degrades, it can lose its reflective properties, reducing the roof’s ability to reflect sunlight and heat. This can cause an increase in cooling costs and reduce the energy efficiency of your building. If you notice a significant increase in energy bills, it’s time to get your TPO roof inspected.
Additionally, you should take some precautionary steps to extend the lifespan of your TPO roofing membrane.
How To Extend The Lifespan Of TPO Roofing Membranes
Like any other roof, TPO membrane also requires proper care and maintenance to last for decades. If you are considering having a TPO roof or already have one installed, you can take some measures to increase its lifespan.
Regular roof inspections are essential for identifying any potential issues early on. The professionals can also inform you how long your TPO roof will last. Early detection and repair of damage can prevent more significant problems down the road and extend the lifespan of your TPO roof.
This includes regular cleaning to remove debris and prevent buildup, as well as repairing any damage or wear and tear promptly. It is best to have a proper roof maintenance plan, which includes everything from inspections to timely repairs.
Proper installation is the first step to making sure that your TPO roof lasts its lifetime. It’s essential to hire a reputable roofing contractor with substantial experience in TPO roofing to ensure that your roof is installed correctly and to the manufacturer’s specifications.
