Box beam gable framing new gable overhang is framed in the form of a box beam hanging off of a new layer of roof plywood roof sheathing cantilevered over the top of the 3 layers of rigid insulation.

You can measure the overhang s edge if you d like but it.
Inadequate nailing of the sheathing to supporting framing or inadequate connections of the framing at the rake edge that supports the roof.

I prefer to install the gable drip edge under the felt though that detail is less critical than at the lower roof edge or eaves.
If the gable end overhang uses the ladder detail method of construction and the length of the overhang is greater than 8 inches to 12 inches you may be able to strengthen the connection of the overhang by installing from the attic inch diameter lag screws that are long enough to go through the gable truss or rafter through the wall sheathing and 1 1 2 inches into the inside framing member of the ladder framing.
