I have some trim Q's before reshingling my house. The rakes & fascias are either 4/4 or 5/4 rough cedar. The ply deck is 1/2" with a 5/12 pitch. The builder used a cedar 1x2 to cover the ply edge and no rake flashing. 1.5" drip with a 1/8" "kick" will nearly cover the face of the 1x2. So I either need a 1" drip (with a kick) or go to a 1x4. Or I could eliminate the 1x, since I'll be using flashing. Also have some water damage (due to no flashing) where the rake & fascia boards are mitered. The joint is 90deg to the decking, not a plumb cut. Poking around with an ice pick shows the damage extends about 4" in each direction. I've cut one out and replaced it with new wood, but wondered if this would be a good place for epoxy or fiberglass? Any suggestions?
