How Do I Know If My Roof Is Actively Leaking Right Now?

Start inside your home. Look at the ceiling for brown or yellow stains, especially if they are growing or darkening. These stains often appear right below a roof leak. Touch the stained area with a dry hand. If it feels damp or soft, water is actively coming through.

Check the attic if you can do so safely. Use a flashlight and look for water droplets on the underside of the roof deck, wet insulation, or dark trails on wood. A musty smell can also signal moisture. If you find any of these, you likely have a leak right now.

• Look for water streaks on walls
• Check for bulging or sagging drywall
• Listen for dripping or running water sounds
• Feel for dampness on ceiling surfaces
• Inspect around vents, skylights, and chimneys

If you find an active leak, place a bucket or container under the drip to catch water. Move furniture and valuables out of the way. Take photos of the leak and any water damage for your records. These photos can help if you file an insurance claim later.

Turn off the water supply to your home if the leak is near a pipe or fixture, but only if you know where the shutoff valve is. This prevents more damage.

Regular roof maintenance helps prevent leaks. Clean your gutters at least twice a year, especially after heavy storms. Trim overhanging branches that can damage shingles. Inspect your roof after strong winds or hail. Catching small issues early can save you from bigger problems later.

If you have an older roof, consider having a water damage inspection done. A professional can identify weak spots and recommend repairs. In Fresno, the hot sun can dry out roofing materials, so check for cracking or curling shingles. Staying proactive keeps your home dry.
