Silicone roof coatings are a popular choice for extending the life of an existing roof, especially on flat or low-slope surfaces. Essentially, these coatings create a seamless, waterproof barrier that reflects UV rays, resists ponding water, and protects against weather damage. However, before re-covering a roof with silicone, it's important to check local building codes and the existing roof system’s warranty. Some building codes limit the number of roof layers allowed, and adding silicone as a re-cover might only be permitted if the underlying roof is in good condition and meets certain standards. You can usually perform a simple visual check for major damage, leaks, or pooling water, but testing adhesion areas by gently scratching the surface can help gauge if the silicone will bond well. If the roof has blistered areas, cracks, or structural concerns, the problem might be more than a coating can fix safely.
If you're considering a silicone re-cover, it's best to call a professional roofer for a thorough inspection to avoid voiding your roof warranty or violating local codes. When discussing the project with a contractor, ask, “Does this silicone coating comply with our local re-cover regulations and building codes?” and “Will applying this coating affect my existing roof’s warranty?” Also, make sure they assess the roof’s drainage and integrity before proceeding. A certified roofer will ensure the surface is clean and dry, and that any repairs are made before the silicone goes on, preventing future problems and maximizing the coating’s lifespan. Taking these cautious steps helps ensure your roof stays protected and compliant.
