Storm damage on a polyurethane roof coating can include cracks, blisters, or sections where the coating has been worn away. These issues happen because strong winds, hail, or heavy rain can physically impact the surface or cause ponding water that degrades the coating over time. The coating's primary job is to protect the underlying roof and provide waterproofing, so any damage needs attention quickly to prevent leaks or more extensive problems. Start by visually inspecting your roof after a storm—look for obvious breaks, peeling, or areas where the coating feels brittle. Using a garden hose to gently rinse off dirt and debris can help you see damage more clearly. Avoid walking on the roof unless absolutely necessary, as polyurethane coatings can be sensitive to pressure. Wearing soft-soled shoes and using a roof ladder for safer access are good precautions.
To keep your warranty valid, it's crucial to follow the manufacturer's recommended repair methods and products. Many polyurethane roof coatings have strict guidelines about who can perform repairs and what materials can be used, so DIY fixes are generally limited to small, clean areas. If you're unsure about the repairs, it's best to call a professional roofer experienced with polyurethane coatings. When hiring a contractor, ask whether they are certified to work with your specific roof system and if they use manufacturer-approved repair materials. Another important question is whether their repair work will be documented and recognized under your existing warranty. Keeping these details clear upfront helps ensure your roof repairs do not unintentionally void your warranty and keeps your roof protected for the long term.
