How would you fix this?

Gary, thanks for all of the great information!!

After reading about how to do stuff the "right" way, it amazes me how builders get away with doing so many things "wrong"!!!

I think the foam board covered with plywood is doable under the cantilever. I may have to dig some more out for access or run screws diagonally top-down through the joists and foam board into the plywood to hold it up.

I have started a new thread on the dryer vent as it is a separate topic.

Two layers, not just behind stucco for "better drainage control" -- Seattle mention, pp.2: http://www.fortifiber.com/pdf/News_I...o%20Layers.pdf

That would help immensely with all the staple/nail holes used to apply it (if the second layer were applied per manu. w. 1st layer just tacked on). Especially with an engineered product under it like OSB, as pictured.

P.S. You are welcome, LNP! Ply below f.b.

I would like to cover the foamboard with PT plywood due to it's proximity to the ground. Is the foil coating made of aluminum? If so, will this be an issue in contact with PT?

Good point! Being so thin, I don't know. Use 1/2" foil-faced below the ply as it needs 3/4" air space to work, 1" (or ?) unfaced above the ply....to be safe.
