Quick answer
Keep people out from under a sagging ceiling, turn off power to fixtures in the area and catch drips in a bucket. Then find the source: the roof, a bathroom above, or the AC drain line in the attic. The ceiling, insulation and framing need to be dried, not just painted over.
Where the water usually comes from
The roof, after storms and hail
North Texas storms are hard on roofs. Texas led the country in State Farm hail claims in 2025, at $1.4 billion. A hail-damaged or wind-lifted shingle may not leak until the next heavy rain, so a ceiling stain weeks after a storm is common.
A bathroom or laundry above
In two-story homes, a ceiling stain under a bathroom often points to a failed toilet seal, a leaking supply line or a tub or shower drain. Look for loose flooring or caulk upstairs.
The AC system in the attic
Many North Texas homes have the air handler in the attic. In summer it produces a lot of condensation. A clogged drain line or a rusted drain pan can overflow into the ceiling below. A stain near an AC closet or return vent is a clue.
Frozen pipes in the attic
Water lines that run through the attic are the most exposed in a hard freeze. In February 2021 DFW stayed at or below freezing for 139 hours, and attic lines in many homes split. See burst pipe water damage.
Staying safe with a wet ceiling
- Watch for sagging. Wet drywall gets heavy and soft. A bulge can give way without warning.
- Electricity: water often runs along wiring to light fixtures. Turn off the circuit before touching anything.
- Old ceilings: textured "popcorn" ceilings in older homes can contain asbestos. Don't scrape or sand it; let a professional test it first.
What a restoration company will do
- Trace the water path from the source to the stain, using moisture meters and, often, a thermal camera.
- Remove wet insulation and any drywall too damaged to save, so the space above can dry.
- Dry the framing with air movers and dehumidifiers, and record moisture readings until it is dry.
- Repair or arrange repair of the drywall, texture and paint once everything is dry.
A ceiling that is only stained, not soft or sagging, can sometimes be dried in place and sealed with a stain-blocking primer before repainting. Painting over a stain without drying the space above just hides the problem.
Questions to ask before you sign
- Where do you think the water came from, and will the source be fixed first?
- Do you need to remove insulation, and how much?
- Will you repair the drywall and paint, or only dry it?
- Can I have a written estimate I can send to my insurer?
Insurance notes
The Texas Department of Insurance says most homeowner policies cover sudden and accidental water damage and exclude gradual leaks. For roof leaks after a storm, the roof damage and the interior water damage are usually part of the same claim. Photograph the ceiling, the attic and the roof (from the ground) before any repairs.
