I have stucco on my house and it leaks. The building paper was not shingled
correctly, and the staples holding the wire on, were drove too deep creating
holes all over the paper (where it pulled the wire through). I am planning
to tear down the stucco, and install Tyvek, and redo the house with either
vinyl siding or Hardiboard.

I know my walls (i.e. the OSB and some insulation) are wet from a recent
rain. Does Tyvek breath well? Should I be concerned about trapping
moisture in the wall? I live in Canada, so we have a vapor barrier on the
inside of the walls i.e. moisture can only move out of the wall through the
Tyvek.
