A water leak, no matter how small, can do a lot of damage to
your drywall. Imagine losing an entire ceiling because the drywall collapsed
after losing its fight against the weight of the water and gravity. So if you
notice small dimples on your ceiling, that’s because the drywall surrounding
the nails or screws has started to droop. But no worries, because you have the
option to have it repaired before worse things could happen.
