Quick answer
If water is near lights, outlets, cords or the panel, do not enter the water; turn power off at the panel only if you can reach it from a dry spot, otherwise call the utility or an electrician. Then stop the water at the fixture valve or main shutoff, or turn off an attic air conditioner, put a bucket under the drip and stay out from under any sagging part of the ceiling. Take photos, work out whether the drip follows rain or runs in dry weather, and get the ceiling dry within 24 to 48 hours, which EPA says prevents mold growth in most cases. [12]
Do this first: the next 15 minutes
An active drip means water is still moving above the ceiling. Work through these steps in order.
Look before you touch. If water is near lights, outlets, cords or the electrical panel, do not enter the water. Turn power off at the panel only if you can reach it from a dry spot; otherwise call the utility or an electrician. CDC says never to turn power on or off while standing in water. [1]
Stop the water if you can. If a bathroom, kitchen or laundry sits above the leak, close the valve behind the toilet or under the sink, or close the main shutoff. A wheel-style gate valve turns clockwise until the water is off; a lever-style ball valve turns a quarter turn. [2]
If an air conditioner sits in the attic above, turn it off. Trane says to turn the air conditioner off at the thermostat or circuit breaker as soon as you notice a drain problem. [3]
Put a bucket, tub or trash can under the drip, with towels or a plastic sheet around it to catch splashes. Stand to one side, not directly under the wet spot.
Keep people and pets out from under any part of the ceiling that sags, bulges or cracks.
Move furniture, rugs, electronics and papers out of the wet area.
Take photos and video of the drip, the ceiling and anything damaged before you clean up. The Texas Department of Insurance says to photograph damage before repairs and not to throw away damaged items until your adjuster has seen them. [4]
Water coming out of a light fixture
Treat a wet light, fan or smoke detector as live. Do not touch it or flip its switch. CDC says not to turn the power back on until wet electrical equipment has been inspected by a qualified electrician. [1] The guide to water coming through a ceiling light fixture covers this case step by step.
Is the ceiling about to come down?
Water that pools on top of drywall makes it heavy. The American Red Cross says a sagging ceiling got wet, which makes it heavy and dangerous. [5] Read the ceiling before you decide what to do next.
What the leaking ceiling looks like, and what to do now
What you see
What it usually means
What to do now
A steady drip from one spot, ceiling flat and firm
Water found a seam, nail hole or fixture opening and is draining through
Catch the drip, stop the source, start drying
A brown ring that keeps spreading
Water is soaking across the top of the drywall
Stop the source; mark the edge in pencil to see if it grows
A bulge or belly in the ceiling
Water is pooling on top of the drywall or plaster
Clear the room and stay out from under it
Cracks, popped tape or drywall pulling off nails
The ceiling is losing its hold on the framing
Clear the room and get help
Water running down the wall below
Water is traveling inside the wall cavity too
Stay clear of outlets on that wall
Water from a light, fan or smoke detector
Water reached the electrical box
Power off only from a dry spot; call an electrician
The Red Cross describes a way to drain a bulge: wear eye protection and a hard hat, stand away from the damaged area, use a long stick, and poke holes starting at the outside edge of the bulge so the water drains out slowly. It warns that striking the center may bring the whole ceiling down. [5] If the bulge is large, sits near a light or fan, or you are not sure it is safe, leave it alone and get help.
Find where the water is coming from
You need to know which kind of leak it is, because that decides who fixes it. A practical point: water can run some distance above a ceiling before it drips, so the leak may not be straight above the drip.
Is it raining, or did it just rain? Then think roof, flashing or gutters. InterNACHI, a home inspector association, says most roof leaks happen around penetrations such as a chimney, plumbing vent, exhaust fan or skylight. [6]
Is there snow on the roof and icicles at the edge? University of Minnesota Extension says water backed up behind an ice dam can find openings in the roof, flow into the attic and stain the ceiling. [7]
Is a bathroom or kitchen right above? Run the shower, then the sink, then flush the toilet, one at a time, and watch the ceiling after each one.
Is an air conditioner above, and is it hot and humid? InterNACHI says an evaporator coil can produce up to 50 gallons of water on a very hot, humid day, and if the main drain clogs, the pan and backup line often do not handle it. [8]
If none of those fit, check your water meter. Most meters have a small low-flow dial that spins even when only a little water passes; if it moves with every tap off, you have a leak somewhere. [9] EPA's WaterSense program suggests reading the meter before and after a two-hour period when no water is used. If it changes at all, you probably have a leak. [10]
If the drip only appears with rain, the guide to a water stain on the ceiling after rain walks through checking the attic safely.

Roof leaks. Do not climb onto a wet or icy roof. The Texas Department of Insurance lists a tarp on the roof as an example of a temporary repair, and says to keep receipts and hold off on permanent repairs until your insurer sees the damage. [4] UMN Extension warns that anyone on a roof in winter risks injury and says it is important to contact professionals for the job. [7]
Water from a toilet. What came out matters. UC Riverside, which follows the IICRC water damage standard, classes an overflow with some urine but no feces as Category 2, gray water, and sewage as Category 3, grossly unsanitary water that can carry pathogens. [11] If a toilet with waste in it or a sewer line is leaking through the ceiling, treat it as Category 3: wear gloves, boots and eye protection, and keep children and pets away.
Dry the ceiling within 24 to 48 hours
Once the water stops, the clock is on drying. EPA says that if wet or damp materials are dried within 24 to 48 hours after a leak, in most cases mold will not grow. [12] The Massachusetts quick reference for water damage says to cut out and discard wallboard that has not been sufficiently dried within 48 hours. [13]
Insulation above the ceiling. A Department of Energy housing brief says wet insulation must be removed for a ceiling to dry properly, and that soaked fiberglass batts and cellulose should be discarded. [14]
Drywall. The same brief says to keep ceiling drywall that was wet only by clean rainwater if it is not sagging, not mildewing and has not lost its smooth texture. [14] EPA's cleanup table says wallboard may be dried in place if there is no obvious swelling and the seams are intact. [15]
Plaster. The DOE brief says plaster that looks undamaged can be kept but will take a long time to dry, and if it separates from its wood lath, that part of the ceiling should be removed and replaced. [14]
Ceiling tiles. EPA's table says water-damaged ceiling tiles should be discarded and replaced. [15]
The room. Run a dehumidifier and keep indoor humidity below 60 percent, ideally 30 to 50 percent. [12] Use fans only once you know the water was clean; EPA says not to use fans before determining that the water is clean or sanitary. [15]
Press the wet area gently each day; a spot that stays soft or starts to sag is not drying. EPA says moisture meters can be used to monitor the drying of damaged materials. [16]
Safe to do yourself
A small drip of clean water, from a source you found and stopped, into a ceiling that stays flat and firm and dries within a day or two, is usually a bucket, towels and dehumidifier job. Patch and paint only after the leak is fixed and the ceiling is dry. NC State Extension notes, for cleaned ceiling tiles, that a stain-blocking coating may be needed before repainting so water stains do not show through. [17]
Insurance and what the repair may cost
Whether a policy pays depends on the cause and on your policy wording. The Texas Department of Insurance says most homeowner and renters policies cover sudden and accidental water damage, such as a burst pipe or a toilet overflow, but usually not damage from gradual leaks or seepage. [4] The Insurance Information Institute lists accidental discharge of water from a plumbing, heating or air conditioning system, or from a household appliance, among the perils covered by common policy types such as the HO-3, and says policies vary, so check yours. [18]
Roof leaks carry a timing catch. Washington's insurance commissioner says that if a storm or accident damages your roof, you need to fix the damage quickly to stop more water from entering, and that insurance will not cover water damage if you delay repairs. [19]
Report it soon: TDI says you usually must report water damage that was hidden from view within days after you first see it. [4] Ask the plumber, roofer or HVAC technician for a written note on the cause.
For budgeting, Angi's September 2026 water damage cost guide puts repair of a ceiling damaged by water at $450 to $1,600, with the severity of the leak as the main cost driver. [20] Fixing the leak itself is a separate bill. The ceiling leak repair cost guide breaks down both parts.
Who to call
Electrician: water reached a light, fan, switch or outlet, a breaker tripped, or you smell something burning.
Plumber: a bathroom, kitchen or laundry is above the leak, the meter test shows a leak, or the drip runs in dry weather.
HVAC technician: an air conditioner or its drain pan is above the leak.
Roofer: the drip follows rain or snowmelt.
Water damage restoration company: the ceiling sags or cracks, materials are still wet after 24 to 48 hours, the water came from a sewer line or a toilet with waste in it, or you cannot find the source.
Many ceiling leaks need two calls: one to stop the water and one to dry what got wet.
Common questions
Is water leaking from the ceiling an emergency?
It is urgent when the ceiling sags or cracks, water drips near a light or outlet, or the drip will not stop. Then keep people out from under it, make the power safe from a dry spot, and get help right away. A slow drip into a firm ceiling from a source you already shut off is less urgent, but it still needs drying within 24 to 48 hours. [12]
Should I poke a hole in a bulging ceiling?
Only if you can do it safely. The Red Cross says to wear eye protection and a hard hat, stand away, use a long stick, and poke holes starting at the outside edge of the bulge so water drains slowly, because striking the center may bring the whole ceiling down. [5] If the bulge is near a light or you are unsure, leave it and get help.
Can a leaking ceiling collapse?
Yes, a ceiling holding water can fall. The Red Cross says a sagging ceiling got wet, which makes it heavy and dangerous. [5] Stay out from under any bulge or crack.
Who do I call first for a leaking ceiling, a plumber or a roofer?
Let timing decide. If the drip follows rain or snowmelt, call a roofer. If it runs in dry weather, sits under a bathroom or kitchen, or your water meter moves with every tap off, call a plumber. [9] If the ceiling sags or stays wet, a water damage restoration company may be needed too.
Will a ceiling leak dry out on its own?
A little clean water in a firm ceiling may dry with a dehumidifier, but wet insulation on top has to come out for the ceiling to dry properly. [14] Massachusetts guidance says wallboard not dried within 48 hours should be cut out. [13]
Does homeowners insurance cover a leaking ceiling?
Often, when the leak was sudden and accidental, such as a burst pipe. Gradual leaks and seepage usually are not covered. [4] For roof damage, Washington's insurance commissioner says delaying repairs can cost you coverage for the water damage. [19] Check your own policy.
