Better would have been to run 2x2s on top of the joists with no nails or screws thru the the tin and would allow water to get out. To late now as your deck would have to have been built 2" lower.

Joe: That's why they put poly over and under the sheet stock.

Presuming you saw all the photos, is the plastic sheeting they put down insufficient IYE?
