How many here actually use ropes and work from the shingles on those high rooflines? I am frustrated with moving ladders or not being able to reach those high points. From a production standpoint, it is worth the increased danger to work from the roof? If so, what equipment do you have (carabiners, kernmantle rope, class II harness, etc), what anchor points do you use. I have mixed thoughts on the increased danger vs. being able to tackle those high rooflines.
