9 Warning Signs of Roof Leaks
9 Warning Signs Your Roof Is Leaking (And What to Do About It)
Your roof may be trying to tell you something. Roof leaks can happen for a variety of reasons — from damaged shingles to flashing failure or hidden ventilation issues. Knowing the signs early can save you from expensive repairs or a complete roof replacement.
Don’t Ignore the Warning Signs
There are several red flags that indicate your roof might be leaking. Some are obvious, while others are subtle and easily missed. Even small leaks can lead to rotten wood, mold, mildew, and interior water damage — just like large ones. Unfortunately, by the time these minor leaks become noticeable, the damage is often extensive.
Why Small Leaks Are a Big Deal
Small roof leaks are frequently missed by the untrained eye. These slow, hidden leaks can persist for months or even years before signs show up inside your home. By then, moisture may have already caused structural damage that requires major repairs or total replacement.
That’s why SonShine Roofing always emphasizes early detection and proactive care. Our goal is to help homeowners across Sarasota, Bradenton, Venice, and the surrounding areas protect their homes and avoid unnecessary costs.
