On a stick framed gable roof, the sheathing has been pushed away from the rafters all along the two outside walls above the birdsmouths.

  1. The ridge is sagging.

  2. The seat cut on the ceiling joists were cut perfectly flush with the top of the rafter.

  3. The outside walls are sagging.

  4. The seat cut on the ceiling joists were cut 10 mm lower than the rafter edge causing it to sag.

The correct answer is: The seat cut on the ceiling joists were cut 10 mm lower than the rafter edge causing it to sag.

If the sheathing has been pushed away from the rafters above the birdsmouths, it is likely due to the seat cut on the ceiling joists being cut lower than the rafter edge. This causes the joists to sag downwards, pushing the sheathing away from the rafters. Options A and C are incorrect as they suggest issues with the ridge or outside walls, which do not directly affect the sheathing. Option B is also incorrect as it does not address the issue of the sheathing being pushed away from the rafters.
