The Science of Silicone Roof Coatings and what makes them Superior to the Competition?

Advantages of Silicone Roof Coatings

Before we get too deep in the science, let’s look at the overall benefits of silicone coatings when compared to other roof coatings. After looking at these advantages and benefits, we can then look at how the science of silicone roof coatings creates these advantages. Silicone roof coatings:

  • Are highly UV resistant, more so than most other roof coatings

  • Are water resistant

  • Have built-in elasticity

  • Are capable of achieving 90% solids content

  • Are impermeable

Each of the advantages described above are made possibly thanks to the scientific formulation of silicone roof coatings. Some of the advantages are thanks to natural properties, others have been specially formulated to achieve certain performance levels.

High UV Resistance

Silicone coatings are highly UV resistant thanks to the tight bond the elements in the material form when cured. Because they are so tightly bonded, they are capable of resisting a high percentage of UV rays. The molecules that make up silicone roof coatings are also highly thermal and photo-stable, which means they are naturally reflective molecules that are being combined together.

Water Resistance

Silicone coatings have been formulated with hydrophobic properties to make them extremely water resistant. Because of the way the elements bond together, the surface of a silicone roof coating – when examined under a microscope – has tiny protrusions smaller than a drop of water. These protrusions make it very difficult for water to grad onto anything and work their way past the surface of the coating.

Built-in Elasticity

While the bonds of silicone coatings are extremely strong and tight, so as to resist UV rays and water, they are also flexible and elastic. The material can flex with different pressures, be it shifting in the building or new forces being applied to the roof surface. Despite possessing a very tight link between the molecules, the science of silicone roof coatings allows them to remain elastic.

High Solids Content

Silicone roof coatings are manufactured by mixing together many different chemicals, beginning with a resin that is 100% solids. Most other roof coatings start with a lower solid base and include filler in the formula which disallows their solid content to get much past 50-55%. This higher solid content allows silicone roof coatings to be installed thicker, in fewer coats, with more precision and a smoother surface.


Again, thanks to the extremely tight and strong bond of the molecules in silicone roof coatings, they are impermeable. Rather than just resisting water and allowing water to run off them, their molecules are so tightly bonded and so complexly organized, they cannot be permeated. This is a significant advantage of silicone roof coatings.


There are many benefits to silicone coatings, but the science of silicone roof coatings is one of their greatest benefits. They have been naturally and specially formulated to be one of the best materials in the construction industry, and they are quite possibly the best roof coatings available.
