Glad the info was of use to you. The Product I used to fill the gap at the edge was made by the company that makes Coravent, a ridge venting system that resembles corrugated cardboard but is made of plastic. I don't know if they have a name for the product I used for the edge, but if interested you should ask at your local roofing supply center. The product I used was about 1" thick, 1.5" wide and 4' in length. I cut it to length between the rafters and stacked it with a 1x2 to fill the gap.
Good luck!
Nathan
