Hey guys, just wondering what people thought about different systems to get up on roofs. I love working off ladders, any height, but am not very fond of being up on steeply pitched roofs. We used to (in my college pro days) just carry around a bunch of 2 foot long 2x4's and nail them directly into the roof...then patch the holes with roof cement as we pulled them out. I tried using some regular roof jacks before, but I thought they took way too long to set up, and it was hard to get the shingles to peel back enough without ripping them to slide the jacks underneath and nail on. I know some guys use single sections of extention ladders with hooks on the end, but walking up and down them seems very dangerous....my preferred method now is to just anchor a roof harness to the peak above where I'm working and not use any jacks at all, but after a hour or so my ankles are just killing me! What do you guys do for roof work?
