I don't know that I'd get too worried about that little bit of moisture.

I would think if you used all glue and not mechanical fasteners that over time the moisture migrating through the concrete from the outside soils would cause the glue to eventually delaminate.

I'd also replace W/ moisture/mold resistant drywall, rather than just use flashing and glue.

I'm working on a rehab for rental and pulled up the flooring (vinyl floor and carpet) and noted there was a ton of moisture (wet) in the existing wood floor.

Is there a lot of moisture on the windows?

., painting over brick is not really maintenance friendly, as moisture (winter) will tend to push the paint away from the brick, even with a good paint, not to mention if your painter only knows how to spread it and doesn't know which primer to choose. 

That definitely eliminates the possibility of wood rotting etc due to moisture in the future...  

If there is damage (extensive moisture, cracks, holes, etc) is may not be a bad idea to replace. 

But if you are storing items that may carry some moisture, cedar alone won't meet your need.

This much moisture soaking into 30" of snow could lead to some roof issues ... not to mention the creation of ice dams and backing of water under the shingles.
