    Yeppers.

    (I have to use "Yeppers" instead of "Yep" because "Yep" does not have the minimum number of characters Brian has this board set to.)

    Hard to tell from the pic, but typically that type of flashing has a lip that extends up from the exposed edge, after an offset to accept the stucco system. They might have only applied caulk at the bottom of the stucco, also not good practice, since it blocks any water that may enter from above from exiting the system. The lip may be there, you just can't see it. Can you get a mirror to look under the flashing? That may provide a better view of the installation order...

    I agree. That flashing should have a lip under the stucco, but the sealant would retain water. If the sealant wasn't there, I wouldn't note it in the report. Since it seems to be sealed, I would note that the sealant should be removed and the flashing examined to ensure it is under the stucco. (another good use for my mechanic's mirror)

    Brian,

    That type of flashing is a sealant flashing. It is intended to be surface mounted and sealed along its top.

    Really. That is how it is made and why it is made that way.

    Not kidding.

    Of course, it goes against all other code knowledge and water drainage knowledge (we know the water is going to be behind that flashing, at least 'some' of the water - that is just supposed to keep 'most' of the water out over the surface from that point down.

    Yeah, they kinda, sorta, sometimes, work ... somewhat.

    I call that type of flashing "a leak waiting to happen".

    Brandon,

    Nah, the leak is already there. Behind the stucco, in the wall.

    Jerry-
    Respectfully disagree, I've seen the type of flashing you mean, it is attached below the caulk line and has a kick out lip at the top to accept the sealant. This is not that type. Sorry.
