Wiring on roof decking - re-roof

[Joe.B]

Anyone ever come across this? Fortunately re-wiring is already part of the job for this one. If the wire had to stay how would you make it safe? Would heavy-duty flashing be enough?

I have seen this countless times. Mostly sheet metal but those nail guns go through anything. pipe is the best.

Romex, .... under shingles. What kind of temperature adjustment must that entail?

Even if you protected it with say 16 ga. metal, would this be outside the building structure and considered a damp/wet location?

Fortunately here it rarely gets above 78F, and this one's on the northside, but I still don't like it. In this situation it is a vaulted ceiling and the finished ceiling is the underside of the t&g roof decking, with the romex being under the vapor barrier I would consider it to be within the building envelope. Both big concerns and I agree that even thick plating (nail plate gage) it's still a hazard. Does that mean there is no safe solution? Do we stick the homeowner with a couple grand extra in work?
