Whether the damage is from a leaking roof or a plumbing leak, repairs are futile until you repair the source of the water. Once you are certain there are no more leaks, proceed with the repairs.
Use a flat putty knife to scrape away the loose paint from the damage. Inspect the drywall. If there is major damage, call a professional drywall repair team.
Without good oil-based primer, the water circles eventually bleed through the repair work. Prevent future repairs by applying the primer and giving it time to dry.
Apply spackling to fill any holes and blend the repairs with the surrounding ceiling.
Once the spackling is dry, apply primer to ensure good paint adherence to the repair work.
Apply the finish coat of paint, mixed to match the surrounding ceiling. It may be necessary to apply more than one coat of paint to ensure the patch blends with the surrounding area.
