Service drop scraping

This service drop is pulled across the rake edge. This is a house near me that I told the utility company about over a year ago and they had someone come by and say it was ok. Isn't it just a matter of time before the insulation gets scrapped off the conductors and it shorts out?

It sure is, unless the insulation is already brittle and crumbling off, then you'd only need contact with a conductive material like rake flashing to get a fiery electrical flash. Only the utility fuse protects it and it's a big one, a super lag. It can vaporize quite a bit of metal before it's over.

I've seen these totally worn through with bare metal rubbing on the shingles.

I'm not advocating that's good, but it doesn't necessarily mean it all shorts and blows immediately; it'll hang around for the big surprise when all the factors line up.

I'd put a sheath on it; if the power company says it "OK", they're not going to restring the drop, and the owner isn't going to install a new service riser.
