TPO vs. PVC — it’s one of the most common questions we get from roofers, especially when choosing compatible accessories.

Quick Breakdown:

  • TPO is more flexible and slightly more eco-friendly
  • PVC offers better chemical resistance and weldability in extreme temps
  • Both are widely used, but they’re not interchangeable

Why It Matters:

Using the wrong type of flashing for the membrane system can compromise the weld and void warranties. That’s why we label everything clearly and offer options in both TPO and PVC.
