Water Coming Through the Ceiling: What to Do

Keep everyone out from under a sagging or bulging ceiling. Wet drywall can fall suddenly and is heavy. If water is near a light fixture or ceiling fan, turn that circuit off at the breaker from a dry floor.

Think about what is above the wet spot. In a two-story home, check the bathroom, laundry room or upstairs AC closet. In a single-story home, it is usually the attic air handler, a supply line in the attic or the roof. Turn off the fixture, the washer valves, the AC at the thermostat or the main water valve.

If the ceiling is bulging, put a bucket under the lowest point and poke a small hole with a screwdriver. Letting the water out in a controlled way prevents a larger section from collapsing and spreading water further.

Move furniture, electronics and rugs out from under the leak. Put plastic sheeting or towels down. Lift furniture legs onto foil or blocks if carpet is wet.

Take photos of the ceiling, the source above, the floor below and damaged items. Insurers ask for these, and they cannot be retaken after cleanup starts.

Water travels along joists and pipes before dripping, so the stain may be several feet from the leak. Restoration providers use moisture meters and thermal cameras to trace it. Common sources here are upstairs toilets, tubs and washers, AC condensate overflows and polybutylene or copper supply lines in the attic or floor system.

The provider checks the wet area, removes soaked insulation and drywall, and aims air movers and dehumidifiers into the ceiling cavity. Upstairs flooring and subfloor are dried too. See upstairs leak and ceiling damage.

Once readings show the joists and subfloor are dry, new drywall goes up, texture is matched and the ceiling is painted. Fix the source first, or the stain will return.

Sudden leaks, like a burst hose or an overflowing AC pan, are often covered. Slow leaks from failed grout or caulk may not be. Report the damage promptly.

Water often appears first at a light fixture or ceiling fan, because the hole in the drywall gives it a path. Turn that circuit off at the breaker before touching anything, and do not turn the light back on until an electrician or the restoration provider says it is dry.

Some homes from the 1970s and 80s have popcorn ceilings, which may contain asbestos. Do not scrape or sand them; ask whether testing is needed before the ceiling is cut.

In a single-story home, water through the ceiling usually comes from the attic: an AC air handler pan, a supply line or the roof. A provider can check the attic safely with the right equipment.

After removal and drying, most ceilings can be repaired within a week of the leak, depending on how long drying takes and the contractor's schedule. Ask the provider for an estimated timeline.

Renters should tell the landlord right away, in writing, with photos. Ceiling repairs are usually the owner's responsibility.

If the stain appeared during or after rain, the roof is the likely source. Call a roofer as well as a restoration provider.

Turning wet lights back on, standing under a bulging ceiling, painting over a stain before the source is fixed and letting a wet ceiling sit for days waiting for an adjuster all make things worse. Shut off the water, release it safely, document and start drying.

Fast action keeps a ceiling leak to one room.

Save (602) 878-5475 in your phone now so you are not searching at night. Show everyone in the house where the main valve, the washer valves and the breaker panel are.

Most ceiling leaks are fixed within a week when the source is found quickly and drying starts the same day. The longer a wet ceiling waits, the more of it has to be replaced and the higher the chance of mold.

Keep people safe, stop the water, release trapped water into a bucket, protect belongings, photograph everything and start drying the same day.
