repairing water damaged sheetrock

Hey all,
I just found this app and its at the same time amazing and intimidating. You think you know so much but there is always another way or at least another idea.
Which leads me to my question.
I am contracted to repair two emergancy staircases in a 9 story building that where damaged by a frozen pipe exploding on the roof. The sheet rock is flaking of and was moist in some areas and has since dried. Do I need to replace the rock or can I scrape, tape and prime with maybe a killz type primer?

Not so much the rock being wet as the water trapped behind it that will cause mold...

When bending rock the first layer is dried out before the second layer is applied.
