Terra Cotta wall cladding

[Bob Elliott]

Any opinions on how or if this should be flashed .
Note the windows are sealed with no weeps.
Did find an opening at urethane on side of ornamental terra Cotta window side above the window and to the side.
The inside wall had what appeared to be efflorescence near the carpet and at the canopy bolt where it went through to the inside for support of a huge metal canopy the it appeared sealed properly.
5 years old rehab on a 1920's building (old warehouse).
No big moisture readings past 8%.

Moisture doesn't pass through the lime paste mortar or the stone.
