Innovation has more relevance in the roofing industry than you may think.

As a result, the number of solutions you can find for roof technologies has increased.

However, the optimal solution for your next project (Silicone or TPO) will depend on the scenario you face. 

Here are some pros and cons of Silicone and TPO to help you make the right decision.

Let’s go!

TPO: What is it?

TPO means Thermoplastic Polyolefin which is a single-ply plastic roofing membrane that goes above the insulation. 

It also provides UV protection and waterproofing to the roofing surface.

TPO Pros:

  • Highly reflective surface
  • Resistant to mold, dirt, and punctures
  • Durability
  • Good performance against ponding water
  • More resistant to foot traffic

TPO Cons:

  • The seams will begin to dry rot and split over time
  • Water will find its way through the cracks and to the screws
  • Water can saturate the insulation
  • Your project will cost 2 to 3 times more


In general, both roofing solutions (Silicone and TPO) have excellent performance.

However, once you face an aging TPO roof, a Silicone Roof Restoration will be the best choice. 

To sum up, Silicone Roof Restoration is an eco-friendly solution that will give you the same benefits as TPO at half the cost.
