Roof Leaking Into Your House? What to Do in the First 24 Hours

By the Jay Global Home roofing teamNJ HIC #13VH13555200Updated September 2026

A roof leak with water dripping from the ceiling is stressful, especially in the middle of the night. What you do in the first 24 hours decides whether this is a simple repair or a much bigger bill. This is the checklist we give our own customers in North Jersey when they call about an active roof leak.

Step 1: Stay Safe

• Keep water away from electricity. If water is near light fixtures, outlets or the electrical panel, turn off power to that area at the breaker if you can do it safely, and call an electrician.
• Watch for a sagging ceiling. A bulging, water-filled ceiling can collapse. Keep people and pets away from it.
• Never go on the roof during rain, wind, snow or ice, or at night. Most roofing injuries happen to homeowners trying to fix a leak themselves.

Step 2: Control the Water Inside

1. Put buckets or containers under the drip, with a towel inside to stop splashing.
2. Move furniture, rugs and electronics out of the way, or cover them with plastic.
3. If the ceiling is bulging with water, a small hole in the center of the bulge with a screwdriver lets it drain into a bucket in a controlled way. Only do this if you feel safe doing it.
4. Check the attic, if you can reach it safely. Put a bucket or a board under the drip and move wet insulation away.

Step 3: Document Everything

Before you clean up, take photos and short videos of the ceiling, the walls, the floor and any damaged belongings, plus the outside of the roof from the ground. Write down the date and the weather. If the leak was caused by a storm, these photos are key to an insurance claim.

Step 4: Find the Source of the Roof Leak

Water travels along rafters and pipes, so the leak on your ceiling is often several feet away from the hole in your roof. The most common sources we find in North Jersey homes are:

Skylights are also a frequent source. Old skylights leak at the frame or the flashing, and water often shows up on the ceiling around them.

Step 5: Call a Licensed Roofer (and Maybe Your Insurer)

A roofer can install an emergency tarp, find the real source and tell you if it's a simple repair or a sign of a bigger problem. If a storm, wind, hail or a fallen tree caused the leak, call your insurance company to report the claim. Most policies expect you to report damage promptly and to take reasonable steps, like tarping, to prevent more damage. The NJ Department of Banking and Insurance also publishes consumer guides on homeowners claims.

Step 6: Dry Out and Watch for Mold

Wet drywall, insulation and wood can start growing mold within 24 to 48 hours. Open windows if the weather allows, run fans and a dehumidifier, and remove soaked insulation and carpet padding. Ceilings that stay stained, soft or sagging after drying should be replaced.

What Not to Do During a Roof Leak

• Don't climb on a wet or icy roof.
• Don't wait for "the next dry week" to call. Every rain makes the damage worse and harder to claim.
• Don't sign with a door-to-door contractor on the spot. Ask for the New Jersey HIC registration number and a local address.
• Don't throw away damaged items before you photograph them.
