Silicone roof coatings are one of the most popular options for restoration projects. Silicone coatings are great for all types of commercial roofing including EPDM, TPO, bitumen, metal, and single-ply. When it comes to choosing silicone coating options, there are a few things to consider. Below are the pros and cons of silicone roof coating options.

Is Silicone The Best For Flat Roofing?

The Advantages

  • Resists Water Ponding: One of the best features of silicone roofing is the ability to resist water ponding. As a moisture-cure substance, it will not absorb any water which allows it to endure ponding water effects and damage.
  • UV Protection: Silicone roofing can reflect between 80-90% of UV rays. The heat and UV damage is reflected away from your rooftop. This not only protects the longevity of the roof but it also cuts utility and energy costs by naturally keeping the building cooler. Silicone will also not degrade or crack under prolonged sun exposure as compared to other elastomeric coatings that get brittle quickly.
  • Weatherability: Silicone roofing is flexible which makes it great for every season. The membrane is impermeable, monolithic, and can withstand oxidation, high temperatures, and heavy winds. Silicone also can endure the expansion and contraction that occurs with commercial roofing during the summer.
  • High Solids: Modern formulations have a high-solids content, typically around 90%. What this means for you is that fewer coating materials are needed to get the desired thickness and coverage. You can save time and money by being able to apply more coating in a single pass of the roof.
  • Environmentally Safe: Most high-solids silicone coatings are solvent-free and also contain very low volatile organic compounds. This makes them one of the safest options in terms of the environment. Silicone meets most state standards and in most cases exceeds them, so is safe for use in all 50 states.

The Disadvantages

  • Difficult to Spray: Silicone is a solvent-based coating, which can be harsh on hydraulic sprayers. All application equipment needs to be properly and regularly cleaned to avoid any installation problems.
  • Easily Attracts Dirt: The coating easily attracts dust and dirt from the air and over time, this accumulates on the surface, interfering with its reflective properties. As dirt builds up, the roof loses its reflective abilities making the roof more susceptible to heat damage. To prevent buildup, you should pressure wash your roof within the first year of application.
  • Can Be Slippery: Silicone is a slippery surface when wet. If used on roofing that gets heavy foot traffic, you should keep the area clearly marked and designate specific walkways for safe use.


Roofing is essential for the longevity of your property, but with constant exposure to the elements, your roofing can deteriorate quickly.
