Signs Your Chimney or Skylight May Be Causing Roof Leaks

Common Trouble Spots Every Homeowner Should Watch For

Not all roof leaks come from missing shingles. In fact, some of the most common problem areas are chimneys and skylights. These roof penetrations look harmless from the ground, but if flashing fails, water intrusion is almost guaranteed.

✅ Chimney Trouble Signs

  • Rust stains on the chimney or roof below it

  • Cracked or deteriorating mortar around bricks

  • Water spots on ceilings near the chimney chase

  • Loose or corroded flashing where the chimney meets the roof

✅ Skylight Trouble Signs

  • Condensation or fogging between skylight panes

  • Stains or peeling paint on ceilings below the skylight

  • Cracks in the skylight dome or glass

  • Water pooling on the roof around the skylight

✅ Why It Happens

Flashing around chimneys and skylights takes a beating from wind, rain, and snow. If it loosens or was installed incorrectly, leaks often show up inside your home long before you spot exterior damage.

Final Thoughts

Chimneys and skylights can be beautiful architectural features—but they require extra attention. If you suspect water intrusion, don’t wait until the damage spreads.
