Any suggestions as to how to get up and stay up on a 12/12 pitched metal roof? The chimney we are replacing is about 8 foot from the edge of the eave. Trying to figure out a way to get there without having to rent a lift. So far, we are thinking of rigging a ladder with 45 degree angle brackets to go over the roof cap. Need to have something in place to repaint the metal roof anyway. Thanks!
