I would like to mount a floodlight on my chimney. I'm not keen on cutting into the roof there to make an entrance for the wire. Every hole in the roof is an opportunity for water intrusion and it's also above a vaulted ceiling - access is difficult and there is nothing to tie into there.
Would it be ok to let the power cord lay on the roof and run around the eaves, perhaps to a high mounted in-use box? It doesn't seem great - don't anyone tripping or slipping on the cord.
I'd like to hear your thoughts on this.
