TPO (Thermoplastic Olefin) roofing is a popular choice for many commercial property owners because it’s affordable and energy-efficient. But while it has its benefits, it’s not a perfect solution for every building. At Central Roofing, we’ve worked on hundreds of TPO roofing systems across Los Angeles and Orange County, and we want to give you a clear, honest view.
Here are three important cons you should know before deciding on TPO roofing for your commercial building:
1. Vulnerability to Punctures and Tears
While TPO is durable in many ways, it’s still more vulnerable to punctures and tears compared to some other roofing systems like Built-Up Roofing (BUR) or Modified Bitumen. Sharp objects, dropped tools, or even heavy foot traffic can damage the membrane, leading to leaks. ➡️ Learn more about flat roof maintenance tips here.
Tip: If you have heavy rooftop traffic (like HVAC servicing), you might want to consider a walkway system or an alternative roofing type that’s more impact-resistant.
2. Inconsistent Quality Between Manufacturers
Not all TPO membranes are created equal. Because there’s no single industry-wide standard for TPO formulation, the quality can vary significantly depending on the brand you choose. Some TPO products may weather faster, crack, or fail prematurely. ➡️ This article by Roofing Contractor Magazine dives deeper into the variation in TPO products.
Tip: Always work with an experienced contractor like Central Roofing who can recommend the best TPO brands based on real-world performance.
3. Potential for Seams to Fail Over Time
TPO roofs are heat-welded at the seams, which creates a strong initial bond. However, over time, these seams can weaken—especially if the roof experiences a lot of temperature fluctuation, movement, or poor installation practices. Seam failure is one of the leading causes of TPO roof leaks. ➡️ If you’re worried about leaks, check out our Roof Leak Repair Services.
Tip: Make sure your contractor offers a solid workmanship warranty and uses certified installers. At Central Roofing, all of our TPO roofing projects are completed by factory-trained crews.
Final Thoughts
TPO can still be an excellent roofing option — especially if you hire a knowledgeable contractor who uses top-quality materials. If you’re considering TPO for your property in Los Angeles, Orange County, or surrounding areas, Central Roofing can help you weigh the pros and cons based on your specific needs.
