TPO Roofing Resources

What is TPO Roofing?

Short for thermoplastic polyolefin, TPO is a single-ply roofing membrane that offers excellent performance at a cost-effective price. Heat-welded seams provide superior strength. TPO's long-term heat, UV, and natural fungal resistance, plus flexibility without need for plasticizers also make TPO a reliable low-slope roofing system.

The benefits of TPO

In the 20+ years that TPO has been in the field, it’s become one the most popular products for low-slope roofs. Over 1 billion square feet are installed annually, making up over 50% of single-ply roofs installed today. TPO’s inherent benefits include:

  • Great Value: Excellent performance at a cost-effective price.
  • Excellent Seam Strength: Heat-welded seams provide greater seam strength to taped and other seams.
  • Long-term Weathering: Excellent long-term heat and UV resistance.
  • Energy Saving: Highly reflective and emissive white surface can help reduce energy costs and urban heat island effect
  • Inherently Flexible: No need for plasticizers
  • Naturally Fungal Resistant: Doesn’t require biocides.
  • Versatile Application: Including high-performance roofs requiring high wind uplift, increased puncture resistance, or quick economical systems
