Then I cut a couple of 8'x2"x6" boards to exactly 96" and put together 2 stop blocks made by screwing a piece of 1"x4" onto a 2"x4" block. The latter I clamped onto each end of my 'plate' to act as spacers to hold each 2"x6" board in place with about a 1" lap over the bottom edge of the roof to provide a drip line. I measured down from the top of the ridge board, adjusted the 2"x6" alignment a bit, to ensure it was parallel to the ridge line, and screwed each into place.
