There are always options when it comes to commercial roofing. Whether you need a new roof installed or looking to replace one that is worn out, you need to consider your options in terms of materials. One of the top options to consider is silicone roofing. Silicone roofing is a coating and it can be applied to most other types of roofing. This new coating offers a seamless exterior and additional weather and waterproof protection. Silicone is not to be used as a standalone material. It is always applied to another roofing system. Older roofing that may have cracks can be covered with silicone. This spray gives your roof some additional life and protection.

Silicone Roofing: What Do You Need To Know?

Pros of Silicone Coating

Silicone coating ($2 to $3.50 per square foot) is cheaper than tearing down a roof teardown and installation ($4 to $10 per square foot).

  • Extends the life of a roof by filling cracks and seams
  • Warranties of 10, 15, or 20-year increments
  • Lower energy costs due to white, reflective surface
  • Quick installation time

Cons of Silicone Coating

  • Nothing sticks to silicone, so it will need to be removed if you ever want another roofing system.
  • Must be installed by a professional as poor installation can be the difference between the coating lasting 1 or 15 years.
  • Silicone can become slippery when wet and a potential hazard if on the roof.
  • Silicone holds dirt so will lose reflective properties over time.

Before considering silicone roofing, your roof must:

  • Be less than 25% saturated.
  • Need to be maintained every year.
  • Have seams that are in good condition.

Silicone Roofing Installation

The process involves spraying a layer of silicone on the roof to cover cracks, seams, and blisters. It can also be rolled onto the roof. This does not do anything to improve the underlying system but will add an extra layer of protection to the roof. This is a good option if your roof is in good condition but has normal wear and tear from aging.


The first step involves an infrared inspection to see if any of the insulation is saturated. These need to be removed and replaced so the roof can then be power washed. Next, the primer is installed, if needed, and then the seams of the membrane are reinforced. Perform all miscellaneous repairs and then spray or roll the silicone coating over the roof. Silicone roofing is an ideal alternative for roof replacement which can be costly and time-consuming.
