I have mold in the ceiling above a bathroom shower. What needs to happen to remove this? Does the roof need to come out and replace part of it or can this be cleaned in the attic? How long and how much should this cost?

You would have to contain the bathroom under negative air pressure and remove the ceiling. Remove insulation from moldy areas in the attic. For the roof plywood, you would need to either treat it with mold remediation products or remove it and replace. Big job if the attic wood is moldy. It would cost around $8000 to hire a company to do it.
