When romex is run across rafters in an open unfinished attic it is my position that a raceway of some kind 1x3 s or even 2x4 s should first be attached across the affected rafters perhaps 3 to 4 above the joists then the wiring be stapled to the raceway. The attic wiring should be protected and secured to ceiling joists or other wood structural supports. This will protect the wiring from being accidentally snagged. It also is easily damaged unlike imc or rigid conduit.
