Ceiling Repairs - Home Repairs
This type of ceiling damage
is caused by a roof leak. The roofing materials are no longer
doing their job and could be worn excessively from age or there
could be a small puncture or hole in the roofing.
This ceiling obviously had a large water leak and over time it
caused the drywall texture to separate from the drywall. This
ceiling also has some sort of mold growing on the drywall. Water
damaged drywall should be replaced, if you want the ceiling
repair to last a long time.
Once the drywall is wet, it's possible for it to dry out safely
with no further damage but you're running a risk over time,
because mold could grow on either side of the drywall and
actually in a situation like this could start growing between
the drywall and the ceiling texture.
When doing ceiling repairs that involve water damage, make sure
you replace the drywall or plaster.
