Moisture on ceiling drywall

Hi, I have hired professional roofers to replace our roof. Soon after they started work and part of the old shingles were already gone, it started raining. They covered the roof with tarp as quickly as they could, but a couple of moisture spots (size 5-6 inches in diameter) still appeared on the ceiling in one of the rooms. They said they would fix all damage, but I am wondering whether there are particular issues I should be worried about: e.g., should I be worried about the studs in the attic getting wet; is it sufficient to just repaint the ceiling drywall, or does it need to be replaced, etc.? Thanks!

First thing I would have done was remove any effected insulation in the attic to help it dry out.
Trash it do not try and reuse it.
Guess you mean rafters not studs if there in the attic, getting them wet one time is not going to hurt them.
If the sheetrock is still soft when it drys out it also will need to be cut out and repaired.

Do as Joe says. If the sheet rock is OK (still hard and firm) use something like KILTZ to block the stain or water mark and seal it. Then use a good grade of ceiling paint. You should be good to go. In most new construction its not uncommon to have a rain storm while framing is being put up. No harm is done. As long as the wood has a change to dry out before being encased in plywood or what ever they might use.

The good thing is with summer's heat anything in the attic will be baked dry relatively quickly. Couple that with AC inside the house keeping the humidity low to help dry the sheetrock from the bottom and you could not have picked a better time for a roof leak.

To seal the water stains you need to use a solvent based primer! The old oil base kilz is ok but I wouldn't trust any latex primer to adequately seal the stains.
