When building a new home is there some way to prevent varying amounts of moisture content from accumulating on or in the ceiling joists through attic ventilation or proper insulation thus preventing rafter lift in the beginning?
Answer:
You can normally get a way from permitting that joint to open by not having ceiling drywall fasteners nearer than 12 to 16 inches from the walls. That way, when the ceiling joist lifts or disconfigures in any direction, ceiling drywall stays where it is because it will bend enough to not tear the tape.
