I cannot figure how to use pump jacks on a steep pitch 9/12 roof so that i can get up to the gable to side it.  House is 44′ long.  So center at peak of gable is about 35′ off the ground.  I have 3 posts and (4) 24′ planks.
Every way i think about it i have the jacks running into the roof tie offs before getting me up to the peak.
Maybe i have to resetup one i get up high enough to just use 2 posts that are set enough to get up me up to the peak with out using a ladder on the scaffold.
