TPO roofing issues are generally associated with aging and seam failures.
TPO was one of the most used single-ply membranes in the last decade and is still very popular amongst many contractors.
However, its failures persist in the states with heavy heat and UV rays exposure.
The National Roofing Contractors Association warns roofing contractors to be aware of the following issues.
Do not stop reading!
1. Adhesive Failures
The UV rays exposure will eventually degrade the adhesives.
This means your seams will be exposed, causing roofing leaks and mold penetration, which may result in structural damage.
2. Peeling, Bubbling, and Punctures
Peeling and bubbling are mainly caused by inefficient installation.
Following the appropriate installation guidelines is mandatory to avoid these issues.
The roof surface has to be completely clean and dry to ensure proper adhesion.
In addition, high foot traffic or hail can lead to punctures as TPO is flexible and lightweight.
3. Longevity
This is one of the most significant TPO roofing issues.
Despite its popularity, TPO roofing systems have been known for their short lifespan compared to other roofing technologies.
It is still a recently discovered roofing technology, which means a lot of improvements need to be made to its formula by manufacturers.
However, it has a good balance between affordability and durability.
Its failures persist in the states with heavy heat and UV rays exposure.
4. Uneven Seams
Uneven seams are just another TPO roofing issue.
This problem relates to production procedures during manufacturing or poor installation.
If you face this type of issue early on during the installation, you should contact a roofing professional immediately.
5. Warranty Problems
When choosing a TPO roofing system, you have to make sure to ask your contractor for a warranty.
Many property managers ask for a TPO system, but they aren’t aware that the warranty usually comes from the manufacturer.
In fact, the warranty should include any necessary repairs for free, at least for the first 10 to 15 years.
How to Avoid TPO Roofing Issues
TPO roofing issues are avoidable, but it is essential to maintain regular inspections.
Without yearly inspections, there isn’t a roofing system that will achieve its full potential lifespan.
