We talk a lot about roof coating restoration and how silicone can save building owners time, money and headaches, but people may still not understand exactly how the process works and the exact benefits . We are going to tackle the basics: what it does, how it helps you, and how you can expect to benefit from it.
The Science behind Silicone Roof Coatings
Before we look at the silicone roof coating process, it is important to understand why we are so passionate about silicone roof coatings. There are many different types of roof coatings on the market today, but silicone is widely revered as the “Cadillac” of the roof coating market. It is generally the most expensive option when looking at material costs, but there is good reason for this increased cost.
Silicone coatings have been developed over many decades for many different applications, and these years of development have made it a strong, UV resistant, moisture curing, non-chalking, environmentally friendly product.

Silicone Roof Coating Installation
One of the strengths of a silicone roof coating restoration that we often tout is the ease of installation and how convenient it is to renew your roof with this system. But what does this actually mean?
If your roof is old, wearing down, leaking, losing energy, getting too hot, or failing in any way that is not structural, restoration coatings can help you. Simply power wash the roof, apply a primer if required (which is rare), and apply the coating to the surface of the roof. You may have to use some caulk and polyester fabric to properly handle difficult protrusions in the roof, but those are typically minimal in time and effort.
That’s it: power wash, primer (if needed), apply coating. That’s the ease of installation that we are always talking about.
What Does Silicone Coating Do during It’s Life?
Once installed, many people don’t know what silicone roof coatings provide, and how beneficial they are. They provide protection from the elements, as coatings create a seamless, waterproof, monolithic membrane that stops leaks and resists ponding water.
Silicone roof coatings are also reflective, meaning they keep the surface of the roof cool despite the sun’s rays, meaning your building stays at the proper temperature. These benefits all come from a system that is spray-applied in liquid form, directly to the existing roof surface. There are no roof deck modifications and no major structural changes made. Simply apply the coating to the existing surface.
What Happens at the End of the Coating’s Life?
So, what happens in 10-20 years after you install a silicone roof coating on your roof? Do you have to tear off the old roof to remove the coating? Do you have to strip and re-apply the coating all over again? No! At the end of the coating’s life, simply re-spray a new coating onto the roof surface, directly onto the previous layer of coating.
It is as simple as re-applying the coating the same way you did before. You will have to power wash the surface again, but no primer will be required. Once the second layer is applied, your roof is under warranty for the manufacturer's designated warranty period which varies by supplier.
So that’s it, a crash course on silicone roof coatings. What makes them so great, how they are installed, what benefits they provide during their life, and what you do at the end of their life to renew the system.
