To understand Silicone Roof Coating systems is to first understand cool roofs. If you’re not sure what exactly cool roofs are, I highly suggest you check out The Definitive Guide: Cool Roof Systems.
With that being said most people who have heard of cool roof coatings probably know about acrylic systems which seems to be the standard for coating systems. But a lesser-known coating system is gaining popularity and that’s Silicone Coating Systems.
Here I’m going to lay everything you need to know the good and the bad about this relatively new silicone roof coating restoration system.
What is a Silicone Roof Coating System?
Silicone coatings are manufactured with a high solids’ dispersion of 100 percent silicone. A silicone roof coating system is a single layer (applied in one or two coats) that’s rolled or sprayed on as a liquid to fill in cracks, blisters, seams and adds an extra layer of protection from the elements.
How long does a Silicone Roof Coating Last?
A good silicone coating could last up to 15 years with proper bi-annual maintenance and inspection.
Can I apply a Silicone Roof System to any type of roof?
Silicone Roof Coating Systems are ideally used for Flat roofs or Low Sloped Roof surfaces.
How much is a Silicone Roof Coating Cost?
A silicone coating system usually costs between $3.25 to $4.00 per square foot.
How much is a Silicone Roof Coating Cost?
AVOID TIME-CONSUMING AND COSTLY TEAR-OFFS. By re-covering, you save on labor costs and avoid landfill expenses, plus your existing roof can be re-covered without any interruption to normal business operations.
EXTEND THE LIFE OF YOUR ROOF. By renewing your roof, you’ll never need to replace the roof again.
REDUCE ENERGY COSTS. The highly-reflective, glossy finish, silicone roof coatings can help reduce energy costs.
Acrylic Vs Silicone Coating Restorations
Acrylic coatings are less costly than Silicone coatings and are also more aesthetically pleasing. As silicone coatings tend to get dirty. However, Silicone coatings beat acrylics where it matters most. Durability, U.V resistance, and ponding resistance. If you have a flat roof you already know how much ponding can turn into major issues. Perhaps silicone coating’s best quality is its resistance to ponding which makes it the best coating application in the market today.
With that being said it’s also important to note that although pound for pound silicones are the best type of roof coating on the market today. It doesn’t mean they are the most appropriate for every roof restoration project. Each project is different and there will be cases where acrylic just makes more sense to install than silicone.

Conclusion
The key advantages of using a silicone roofing system:
- Silicone is permanent and will not degrade, chalk or crack under harsh UV rays.
- Silicone forms a seamless membrane that withstands permanent ponding water without softening.
- Silicone creates a smooth surface that offers excellent resistance to mold, mildew, and staining
The key disadvantages of a silicone roofing system:
- Some of the drawbacks are cost,
- application requirements, and the fact that there are only a few materials – other than silicone – that can be applied directly to the silicone surface.
- Silicone also holds dirt on the surface and loses reflectivity over time.
A Silicone Roof Coating system provides a proven, guaranteed solution for renewing your weathered roof. They can be applied to virtually any existing roofing surface to create a seamless membrane that protects against permanent ponding water, ultraviolet light, and severe weather.
