A ceiling leak usually comes from one of four places: the roof, plumbing above, an air conditioner's drain line, or a neighbor upstairs. The first job is the same for all of them: protect what's underneath and check whether the ceiling is holding water.
Likely the roof, flashing around a chimney, skylight or vent, or a gutter backing up. Call a roofer. A tarp over the roof is a job for them, not for a wet roof in a storm.
Likely a supply line, drain, toilet seal, or shower pan above. Shut off water to that fixture or the main, then call a plumber.
An air handler in the attic can overflow its drain pan if the condensate line clogs. Turn the AC off and call an HVAC technician.
Apartments and condos: tell the neighbor above and the building manager or landlord right away, in writing as well.
Not raining, and nothing obvious upstairs? Watch the water meter with every tap off. If it still moves, water is running somewhere, and a plumber can trace it.
The ceiling sagged, collapsed or is soaked across a wide area, insulation above is wet, water ran for hours, or the room still feels damp after two days.
A stain or small wet patch you caught quickly. Once the leak is fixed, dry with fans and a dehumidifier and check that the spot stays dry.
An old, dry stain from a leak that's already fixed. A stain-blocking primer and paint often handles it. Confirm with a moisture meter if you have one.
Storm damage that suddenly opens a roof is commonly treated differently from a roof that leaked because it was worn out, and a sudden pipe failure differently from a slow drip. Photograph the ceiling, the source if you can see it, and anything damaged, and call your insurer early. If you rent, your landlord's insurance covers the building, and your renters policy (if you have one) may cover your belongings.
Not sure where yours is coming from? Ask the advisor and send a photo of the spot.
It depends on the source. A roofer if it leaks when it rains, a plumber if there's a bathroom, kitchen or pipes above, an HVAC technician if it happens when the air conditioning runs, and the building manager or landlord if there's a unit above you. Call a water damage company if the ceiling sagged or is soaked, or the area stays damp after two days.
If the bulge is small, away from light fixtures and wiring, and you can reach it safely, making a small hole at the lowest point over a bucket lets the water drain in a controlled way and often limits damage. If it's large, near electrical fixtures, or out of reach, keep people out of the room and get help.
Not always. Drywall that sagged, softened or stayed wet usually needs replacing. A stain from a leak that's been fixed and has fully dried can often be sealed with a stain-blocking primer and repainted.
