Water Coming Through the Ceiling: What to Do First

1. Contain it. Get a bucket or container under the drip, and move furniture or valuables out of the way.

2. If there’s a bulge or sag in the ceiling, that’s water pooling above the drywall. Carefully puncturing the center of the bulge with a screwdriver (holding a bucket underneath) can relieve the pressure in a controlled way rather than letting the ceiling collapse on its own. Only do this if you can safely reach it.

3. Cut power to any electrical fixtures near the leak if it’s safe to access the breaker — water and electrical don’t mix, and this is a genuine safety step, not just property protection.

4. Photograph the damage before you clean anything up, for insurance and repair documentation purposes.

5. Call for an inspection. Don’t wait to see if it stops on its own — a leak that’s active during one storm will very likely be active during the next one too.

What Not to Do in the Moment

Avoid the temptation to go up on the roof yourself to look for the source while it’s actively raining or still wet — this is a genuine safety risk, and you’re unlikely to accurately diagnose a flat roof leak from a quick look anyway, given how often the visible roof-level cause isn’t obvious even to someone experienced. Also avoid drilling or cutting into the ceiling yourself beyond the controlled pressure-relief puncture described above, since improper cutting can cause more extensive drywall damage than necessary.

The single most useful thing you can do in the moment is contain the water and get help on the way, rather than trying to fully resolve it yourself.
