What is a TPO Roofing System?

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 most common TPO material is bright white with highly reflective properties. This bright white roof installation can reflect UV rays and heat from the building, saving money during the summer months from decreased energy usage to cool the building interior.

The Benefits of a TPO Roofing System

In the 20+ years that TPO has been in the field, it’s become one the most popular products used for low-slope roofing. Over 1 billion square feet are installed annually, making up over 50% of single-ply roofs being installed today. The rapid rise in popularity can be associated with several of TPO’s inherent benefits, including:
• 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 Methods: Including high-performance roofs requiring high wind uplift, increased puncture resistance, or quick economical systems.

During the inspection, a roofing contractor will be able to tell:

  • Where water is entering your insulation
  • How old is the TPO roof
  • How many layers does the roof have
  • What condition are the seams in


After the complete infrared survey, it’s determined that the roof doesn’t have much saturation. If your roof is under 25% saturated, then what can be performed is a silicone restoration membrane system.

What will happen during a silicone restoration membrane installation is:

  • The saturated areas will be removed and replaced with similar material
  • The entire field of the roof will be power washed and cleaned
  • The seams of the TPO roof will be strengthened and reinforced
  • Then silicone coating will be applied to the entire field of the roof
  • Then a new 10-20-year warranty will be granted
