Roof Leak Warning Signs to Check Before Winter Rain

Look for new water marks inside and visible roof damage outside before the rainy season. A stain or drip is a reason to investigate, but it does not show exactly where water entered. Have the roof assessed rather than patching a guessed location.

Signs to notice indoors

Pay attention to new or growing ceiling stains, damp drywall, peeling paint, a musty smell that follows rain, or moisture in the attic. Note when you first noticed the sign and whether it appears after a specific rain event. Keep photos and avoid touching electrical fixtures or wet wiring.

Signs to notice from the ground

Look for missing or displaced roofing materials, debris in valleys, damaged gutters, and water marks on exterior walls. Use a safe vantage point. Do not climb onto the roof, especially during rain, wind, or after damage.

The California Coastal Commission recommends inspecting roofs for wear or damage that could worsen during intense rainfall (California Coastal Commission guidance). This is a reason to address a known concern before storms, not a guarantee that a roof will fail.

What to do if you find a concern

Take clear photos from a safe location, note the date, and contact a qualified roofer to assess the source and scope. If water is actively entering, protect people and belongings from the affected area and contact an appropriate professional. Do not make temporary repairs on a wet or unsafe roof.

Ask for a written explanation of the recommended repair, its limits, and what could change the scope if concealed damage is found. A localized repair may be enough; replacement should be considered only when the roof’s condition supports it.
