If that's a common wall to the right, the first 4 feet of roof sheathing is required to be fire retardant treated, or, protected with Type X drywall. That 4 feet is not measured from the center of the wall, it is measured from each side of the wall.

Protecting that is going to be difficult as that also needs to be done to the sheathing beyond the valley, and, that fire separation needs to continue out to and over the soffit, closing the soffit off into separate sides.

Michael may be seeing something else too?
