Don’t Ignore these Warning Signs of a Roof Leak

A roof leak might start small, but it can quickly lead to major damage if left unaddressed. Whether caused by storm damage or general wear and tear, a leak can impact not just your roof but also your ceilings, walls, insulation, and even your home’s structure. Catching the warning signs early can help you prevent costly repairs and protect your home. At Di Paterio Contracting, we provide expert roof leak repair in Westchester County, NY. Here are four common indications that your roof may be leaking.
Water Stains on Ceilings or Walls
One of the most noticeable signs of a roof leak is a brown or yellowish stain on your ceiling or upper walls. These stains are often caused by water slowly seeping through the roofing material and dripping onto the drywall. The stain might grow over time or appear suddenly after a heavy rain. If you see discoloration in areas near the ceiling, it’s time to investigate further.
Dripping Water or Moisture in the Attic
If you venture into your attic and notice dripping water, damp insulation, or the smell of mildew, there’s a good chance you’re dealing with a roof leak. During or after a rainstorm, check the attic for any signs of moisture intrusion. Water can enter through damaged shingles, flashing, or roof vents and slowly saturate materials underneath, creating a breeding ground for mold and rot.
Missing/Cracked/Curling Shingles
Your shingles are the first line of defense against the elements. When they become damaged, the underlying layers of your roof are vulnerable to water intrusion. If you see shingles that are missing, cracked, or curling upward at the edges, your roof’s waterproof barrier may be compromised. Over time, this can allow water to penetrate and cause leaks beneath the surface.
Mold/Mildew on Exterior Walls
Excessive moisture from a roof leak can cause mold or mildew to appear not only inside your home but also on your exterior walls. If you notice green or black streaks forming down the side of your house—especially near the roofline—it may indicate that water is getting behind your siding. This often occurs when flashing or gutters are damaged or clogged, redirecting water improperly.
