I've been reading here a bit, and think this will be fine. But... Situation: No, there is no I&W shield planned. This is a shop that will be used infrequently when it needs to be heated, and then it will neither get real warm nor for more than several hours at a time. I therefor don't think the I&W would be beneficial, and it is 10 below right now w/ slight frost on the plywood no matter how much I sweep. The I&W would never stick. I've gotta get this puppy closed in before the temp drops. I will be doing a good job air sealing, too, to avoid moisture escaping the conditioned (rarely) space. The facia board is drawn a bit funky, but it will be a normal 2x6 beveled on the bottom for drip collection. I am planning on leaving a small gap between the drip edge and the plywood so the plywood can be re-treated now and then w/ facia. There will be no normal gutters; 3' overhangs and likely ground gutters instead. Ply will overhang the facia by 1/2", D-drip will stick out 1/4" from ply, and shingles will overhang D-drip by 1/4-3/8". Goo will go between D-drip and felt, and starter shingles will be generously goo'd (next spring). Thanks for any comments.
