Ceiling stain under a roof leak
Water from a roof or a flashing wets the attic insulation and runs down to the ceiling. The stain is usually a ring that grows, and the board is read across the area the water spread over, not just the ring.

Drywall and Ceilings
Drywall and Ceiling Water Damage: what it covers
Quick answer
Drywall that takes water in Snellville swells, softens and can lose its paper face, and the moisture often runs along the stud bay well beyond the stain. The job is to read the wall and ceiling through the cavity, dry them to their goal and decide which boards can stay.
A drywall ceiling is a common place for water to show first. A roof leak, a split line in the wall above or a bathroom fan vented into the attic can wet the board from above, and the stain may spread across a large part of the room before anyone looks up. The board sags, the paint lifts and the seam begins to separate.
Most of the houses built in the 1970s to 1990s across the surrounding subdivisions use drywall on wood framing. That construction dries faster than plaster, but it can hold water in the paper face and the bottom plate for much longer than the surface suggests, and a board that looks dry from the room can still be wet at the stud.
The reading starts at the stain and moves outward through the whole ceiling and the wall below any wet area. The board is not judged by its look. It is judged by the moisture in it, and the drying runs until the readings say it is back within its goal.

Warning signs
Signs you need drywall and ceiling water damage
Keep the room below a sagging ceiling clear, do not stand under a bulge, and wear eye protection when a board is opened. Turn off the power to any light fixture in a wet ceiling before touching it.
- A ceiling stain with a brown ring that grows larger after each rain
- A bulge or a sag in the drywall that feels soft when pressed lightly
- Paint that bubbles or peels along a seam or a corner of the ceiling
- A wall that feels damp near the floor after a storm or a shower
- A seam that opens or a nail pop that appears along a wet ceiling
- A musty smell in a closet wall that backs onto a bathroom or attic hatch
Our process
How our drywall and ceiling water damage visit works
Find the source above the stain
The attic, the roof above and the wall or line running into the ceiling are checked. The stain is the end of the path, and the source is found by following the wet insulation or the framing back toward the water.
Read the board across its whole area
Meters are used across the ceiling and the wall below, not only at the stain. The thermal camera shows the cooler, wetter zone, and the meter readings confirm where the moisture is held.
Relieve the water and make a small opening
Standing water in a sagging ceiling is drained through a small, controlled opening. The opening is made where the board is most swollen, so the rest of the ceiling is not pulled down by its own weight.
Dry the cavity and the framing
Air is moved through the joist bays or stud bays until the readings reach their goal. Insulation that is wet is removed from the attic side, since it holds water against the board.
Decide what stays and what goes
A board that dries back to its goal and has not lost its face or its seam is often kept and painted. A board that has softened, separated or sagged is cut out and replaced, and the decision is recorded.
Can drywall that got wet be dried and kept?
Sometimes. Board that has dried to its goal, with its paper face intact and its seams still tight, can often be kept, sealed and painted. Board that has softened, crumbled or separated from its framing is replaced.
The test is whether the board still holds its shape and its face. A stain that dries to a faint ring on a sound board is often a paint problem rather than a structural one. A board that bows, sags at a seam or feels soft when pressed is not going to recover, and it should be cut out.
The framing behind the board is read as well. Wood that stayed wet for a long time can swell or rot, and that wood needs drying or replacing before any new board is fixed to it.
Why does drywall hold water in the cavity so long?
The paper face and the gypsum core absorb water, and the stud bay can hold it against the board. The surface dries first, and the cavity behind it stays wet for a long time.
A ceiling that has taken water from above holds it in the insulation and the joist bay, and the gypsum draws it up from below. The drying has to reach the top of the board from the attic side as well as the room side, which is why the attic is read.
Insulation that stays wet is the slowest part to dry. It is removed where it is saturated, and the board is dried from the open side while the joists are dried from above.
What should be photographed and kept before the board comes down?
Photographs of the stain, the sag and the room below, plus a note of the readings and a sketch of any openings, should be kept before any board is removed.
A photograph from the room and one from the attic help show the path the water took. The readings, with their location and the date, show where the board was wet and how it dried. Those are the things an insurer asks for when the ceiling is part of the claim.
Keep any board that was removed until the insurer has seen it or has said in writing that it can go. The record should say where and when it was discarded.
How is the ceiling finished after it has dried?
Patching, skim coating and painting are separate stages. They are quoted by the trade that does that work, after the drying readings are complete.
A small area of replaced board is taped and finished to match the texture of the ceiling around it, and the paint is matched as closely as possible. A larger area may need the whole ceiling replaced, and that is a larger job with its own quote.
Closing the ceiling before the readings are dry is the most common reason a repair cracks or stains again. The restoration record shows when the ceiling reached its goal, and the finish should wait for that record.
How is the paint treated after the ceiling dries?
A dried ceiling is primed with a stain-blocking primer before it is painted, so the old stain does not show through the new coat. The prime and the paint are applied after the readings are complete and the ceiling is sound.
The record notes the primer used and the date, since a stain that returns through a fresh coat is a sign the readings were not yet at goal when the ceiling was closed.
Options
Types and options for drywall and ceiling water damage
Ceiling below a split line or fixture
A split supply line or a leaking fixture in the room above puts water on the board from above. The board is often sagged in a single spot, and the drying is planned from the readings around it.
Wall below a shower or tub
Water that gets behind a tub surround or a shower pan wets the wall cavity and the bottom plate. The board is opened low on the wall where the readings are high, and the floor under the bath is read as well.

Why drywall and ceiling water damage is different in Metro Atlanta, Georgia
Drywall ceilings in the 1970s to 1990s subdivisions of Lilburn, Redan and the Snellville area are a common place for a roof leak to show, and the attic is read on every ceiling call.
Ceilings under bathrooms and laundry rooms on the upper floor are the places a split line most often shows in newer houses, and the trace runs through the stud bays to reach them.

FAQ
Drywall and Ceiling Water Damage FAQs
Why does the stain keep coming back after I painted?
Water still in the board or the insulation can push the stain through new paint. The ceiling was closed before it was dry, and the readings show whether that is the cause.
Will the whole ceiling need replacing?
Only where the board has softened, separated or sagged. Board that dries back to its goal can often stay, and the readings decide which case applies.
Is a ceiling stain from a roof leak covered by insurance?
Sudden damage from a roof leak is often treated differently from long-term leakage, and the policy and the insurer decide. Keep the photographs and the readings.
Should I cut a hole in the ceiling myself?
Not until the power is off and the room below is protected. A small, controlled opening made by the technician is better than a larger one made in a hurry.
How long does drywall take to dry?
It depends on how much water it took and how long it sat. The drying runs until the readings reach their goal, not for a set number of days.
