How Long Does a Silicone Roof Coating Last? Have you ever wondered when your old roof will start leaking again? Or do you wonder why some roofs have a bright white color? If the answer to each of these questions is yes, you’re in the right place. In this article, we will help you do that math to know how long a silicone roof coating should last. In addition, we will briefly explain the important things you need to know about a silicone roof coating, the white color on roofs.
What Is Silicone Roof Coating?
It is a single silicone layer rolled or sprayed directly onto a roof in one or two coatings. It is also known as Silicone Restoration Membrane. Silicone coating covers any blister, crack, or gap. And due to its white color, it is suitable for most climates as it reflects heat and ultraviolet (UV) rays from the sun.
How Long Does a Silicone Roof Coating Last?
Fifteen years! At least. Yes, you read that right. With the right coating thickness, regular maintenance, and examination after any harsh weather-related incident, a good silicone coating can last more than a decade. You can now start doing the math to know when next to do a restorative coating.
Is This Roof Coating System Any Good?
The short answer is yes. Silicone roof serves as an extra layer to shelter you from the environment.
Here are the main benefits of this coating system:
It prevents ponding water
The most significant advantage of a silicone roof coating is its tolerance for ponding. Ponding is the unwanted accumulation of standing water on flat surfaces which can cause damage like water penetration and leaks on flat roofs. A silicone roof coating can effectively withstand the adverse effects of ponding because it doesn’t absorb any more water after hardening.
Elasticity and impermeability
Roofs are constantly exposed to the environmental factors they shield us from, causing them to expand and contract as the weather demands. Silicone-coated roofs have a highly flexible and impermeable membrane that allows them to retain their strength and durability through many seasons.
It is the perfect UV shield
Silicone roof coating easily deflects ozone and harmful UV rays. It won’t deteriorate, erode, or crack when exposed to sunlight. This helps you to maintain lower energy bills, decrease interior temperatures, and extend roof life.
A lot of solids
A lot of silicone coating formulations now include a high solids percentage. That is, less coating material is needed to reach the required thickness and maximum adhesion. This helps to save time and labor expenses while maintaining the quality of the silicone coating.
It is safe for the environment
High-solids formulations of silicone coating are the safest for the environment. They have zero hydrocarbon solvents content and exceptionally low levels of volatile organic chemicals (VOCs).
The bright white color of the silicone roof enables it to reflect sun rays, reducing the overheating of the roof and interior. As a result, there is an obvious decrease in the energy required to cool the air and you can save a lot of money during the warm seasons. And because of this feature, it is sometimes referred to as a “cool roof”.
When it comes to protection against ozone, UV rays, and moisture, a silicone roof coating is the best choice. It doesn’t only have great flexibility and tolerance to harsh weather conditions; it also degrades slower than other coating options. Well, now you know how long a silicone roof coating lasts and why buildings have white roofs.
