I had third floor addition framed. The roof at the back of the house is cottage style. The way they framed the cathedral ceiling is that the corner rafters is sticking out more than the others. I am attaching pictures to show what I mean. I wonder what should I do to properly hang the drywall so it is installed properly. Hopefully I don't have to beef up the rafters that are on the ceiling to make them equal with the corner rafters.
