Ceiling Water Damage
The roof is the cause; the ceiling is the consequence. Both need attention, and in that order — repainting over a damp ceiling just hides what is growing inside it.
If the ceiling is bulging, act now
A pocket of water in a ceiling weighs far more than drywall can hold, and a collapse drops all of it at once. Pierce the lowest point of the bulge with a screwdriver and let it drain into a bucket. A small deliberate hole is much cheaper than a failed ceiling.
Turn off power to the area at the breaker if water is anywhere near a light fixture, fan or outlet.
Dry it before you repair it
Wet insulation does not recover its R-value and does not dry in place — it has to come out. Drywall that has been saturated and has lost strength has to come out too. Air movement and time are what dry the cavity.
Closing it up before it is dry is how mould problems start, and in Sacramento's humidity the cavity can hold moisture longer than you would expect.
What to photograph
- The stain as it appears, dated, before any repair
- The bucket or container and the water collected
- Damaged belongings, flooring and furniture
- The attic above, if it is safe to access
- Everything again once the ceiling is opened up
Sequence
Stop the water, dry the cavity, repair the roof properly in dry conditions, then repair the interior. Interior finishes go last because they are the only part that is purely cosmetic.
We hold a General Building licence, so roof and interior repair can sit under one contract rather than leaving you to coordinate two trades.
Common questions
Should I poke a hole in a bulging ceiling?
Yes — at the lowest point, with a bucket underneath, and with power to the area off. A controlled hole is far cheaper than the ceiling letting go all at once.
Does wet insulation need replacing?
Yes. Saturated insulation loses its R-value permanently and holds moisture against the framing. It does not dry in place usefully — it has to be removed.
