Why Choose TPO and PVC for Your Flat Roof?


When it comes to flat roofing in Portland, TPO and PVC stand out for good reasons. Here’s what makes these materials a smart choice:

  • Durability That Lasts: Both TPO and PVC are built to handle Portland’s changing climate. They flex with temperature shifts without cracking, ensuring long-term protection.
  • Energy Efficiency: TPO reflects a large portion of the sun’s heat, helping keep your building cooler and reducing energy bills during warm months.
  • Strong and Resilient: PVC offers exceptional resistance to punctures, tears, and harsh weather, making it ideal for buildings that need rugged, reliable coverage.
  • Waterproof and Seamless: These materials create a tight, waterproof barrier that stops leaks before they start, perfect for Portland’s rainy environment.
  • UV and Chemical Resistance: TPO and PVC stand up to harmful UV rays and chemicals, maintaining their strength and appearance over time.
  • Fire Resistant: PVC especially provides extra safety by resisting fire and related hazards.
