While we are on the subject of a pitched roof, I'd like to know how to
attach a safety harness cable. I have a deadly fear of ledges ( not heights,
as a pilot that would be quite a problem ). This fear of ledges would be
greatly reduced if I felt secure in a safety harness. Where and how would I
attach this on the roof without drilling any holes? I've watched contractors
run around with their safety harnesses but I couldn't see how they where
attached.

I hope this is all legible, my mother tongue is French.
