Ceiling water damage is a common problem that can result from a variety of sources, including roof leaks, plumbing leaks, or condensation. The first step in dealing with ceiling water damage is to identify the source of the leak. **When should I be worried about water stains on my ceiling?** Not all water stains on the ceiling are cause for concern. Small water stains that are isolated to a single area may simply be the result of a minor leak that has since been repaired. However, larger water stains or stains that are spreading are cause for concern and should be investigated by a professional. **Signs of a ceiling water leak** There are a number of signs that may indicate a ceiling water leak, including: * Water stains on the ceiling * Sagging or bulging ceiling tiles * Peeling or bubbling paint * Mold or mildew growth * A musty odor * Increased humidity in the room If you notice any of these signs, it is important to take steps to identify and repair the leak as soon as possible. Ignoring a ceiling water leak can lead to further damage to your home, including structural damage and health hazards.
