Water Coming Through the Ceiling: What to Do Right Now

Act now: water and wiring overhead

Do this now

  1. Step back first. Keep everyone, kids and pets too, out from under the wet part of the ceiling and away from any light, fan, outlet or appliance the water is reaching. Do not touch anything electrical that is wet, or anything electrical while you are standing in water. If the ceiling is bulging, or you hear cracking or shifting sounds, the room may not be safe to enter. Stay out of it. Next, turn off the water.
  2. Turn off the water at the main valve inside the house. If there is no main shut-off valve inside, turn it off at the main shut-off valve at the curb or near the water meter. Leave the faucets turned on. If the break is in a hot water pipe, also close the valve on top of the water heater.
  3. Water reaching a light, fan or wiring? If the electrical panel is dry and you can reach it without stepping in water or crossing a wet floor, turn off the power at the main breaker or fuse. If the panel is wet, or you would have to stand in water or cross a wet floor to reach it, leave it alone and call an electrician to turn it off. Never operate a breaker or switch that is wet, even just to turn it off.
  4. In an apartment or condo, the water may be coming from the unit above. Tell your upstairs neighbor. If you rent, report the leak to your building owner or manager right away.
  5. Call a licensed plumber to find and fix the break. If water got into a light, outlet or wiring, call an electrician too, and keep that power off until a qualified electrician has inspected it.
  6. Dry water-damaged areas and items within 24 to 48 hours to prevent mold growth. Open doors and windows and use fans to dry wet areas. If you shut the power off, do not turn it back on to run fans until a qualified electrician has inspected it, and never use a fan or other appliance while standing in water. Throw away soaked things you can't clean or dry quickly.

Can you fix it yourself?

Water off and drying, yes. Ceiling and wiring, no.

Your part is the safe stuff: keep people clear, turn off the water at the main, and start drying. The repairs are not DIY. Georgia EPD's advice when pipes burst is to call a licensed plumber. Water-damaged wiring can be very dangerous and needs a professional, and CDC says not to turn the power back on until a qualified electrician has inspected the electrical equipment. A ceiling showing signs of stress, like sagging or cracking, should be inspected and repaired as soon as possible.

What to ask the plumber

Questions we hear

Water is dripping from my ceiling light. What do I do?

Treat it as an electrical problem first. Do not touch the fixture or a wet switch, and do not touch anything electrical while you are standing in water. If the panel is dry and you can reach it without stepping in water or crossing a wet floor, turn off the power at the main breaker; if not, call an electrician to turn it off. Keep that power off until a qualified electrician has inspected it. If someone gets a shock, do not touch them, because they may still be in contact with the source. Call 911.

Is it the roof or a pipe?

It can be either. The Red Cross lists water pipes in unheated attics among the ones that freeze most often, and water expands as it freezes, which can break a pipe. IBHS says frozen pipes and leaky roofs are among the most common causes of winter water damage claims. Either way, CDC's advice is to fix leaks in roofs, walls or plumbing as soon as you can.

Will the ceiling fall?

It can. A sagging ceiling might be holding water and could be very heavy. Western Australia's building regulator lists water leaks among the causes of ceiling failure and warns that a collapsed ceiling can seriously injure anyone underneath. Warning signs include loud cracking sounds and sagging or dropping of the ceiling board. CDC says to leave a building if you hear shifting or strange noises, since that could mean it is about to fall. Stay out from under it and have it inspected and repaired as soon as possible.

How fast do I need to dry it?

Within 24 to 48 hours. EPA says that if wet materials are dried within 24 to 48 hours after a leak, in most cases mold will not grow. Insulation and ceiling board that got soaked may need replacing, so have whoever does the repair check above the ceiling.
