I worked for a roofing company for a while. We were required to tie off all ladders. However, on most houses, there's nothing to tie to. I've seen ropes tied to rain gutters and about everything else. Most tieoffs won't help a bit to prevent a fall. What it mainly accomplishes is keeping the ladder from sliding off the roof and leaving you stranded up there.
Been reroofing my house using an extension ladder to get up on the roof. I cheated, I extended it 4' above the roof, drilled holes thru the feet and use deck screws to screw it to the deck.laid a 2x4 along the front of the fascia and screwed it down after which I drilled holes in the ladder rails screw the ladder to the 2x4 on the fascia. I am 65 can't afford any dumb mistakes, so far so good. MB
