Silicone roof coating is a flexible, waterproof sealant applied over existing roofs to extend their life and improve resistance to weather, UV rays, and ponding water. It’s popular because it can be added on top of many roof types without removing the old material, reducing waste and labor. Over time, however, this coating can degrade due to harsh sun exposure, dirt buildup, and extreme weather cycles. You might notice cracking, peeling, or loss of adhesion, which can lead to leaks or reduced protection. A simple way to check is to look for any areas where water pools or the coating looks dull and flaky. Gently press the surface in different spots; if it feels brittle or powdery, that’s a sign it may need refreshing or replacing soon.
While you can do some of these inspections yourself, safely climbing onto the roof depends on your comfort with heights and roof pitch. Use a sturdy ladder and avoid slippery conditions. If you see obvious damage, worn spots, or if it’s been more than 10 years since the last application, it’s worth calling a professional roofer. They can assess whether a new silicone layer will stick properly or if more extensive repairs are needed. When talking to a contractor, ask about their experience with silicone coatings specifically and whether the product they use has a warranty that covers common issues like peeling or cracking. Also, clarify the estimated lifespan after recoating and whether the price includes surface preparation, which greatly affects the coating’s performance and longevity.
