Stucco Transition Flashing Question

When not using a weep screed, the flashing should have a casing bead. Three questions:

  1. anyone have picture of a casing bead?

  2. what are the ramifications of no casing bead?

  3. Do you find the illustrated flashing to be a defect?

Thanks guys.



1 deficient recent inspection attached

2 h2o can become entrapped, wick, and cause the breakdown of supporting sheathing and structural members

3 if it is not perforated and there is no bond break between the stucco & metallic flashing where will the moisture go

also do you know for sure that non-approved termination metallic flashing has a leg that is behind the required wrb

don’t hang your a s s out if you don’t know & make everyone clearly aware of what you do know

Here’s what I ended up saying about it. Thanks a bunch Barry.


We could not confirm the proper installation of a rain screen at the lower terminations of the stucco walls where it transitions to another wall cladding. The stucco also appeared to be missing a casing bead which supports the stucco off the transition flashing. Stucco walls are porous; if water were to penetrate behind the wall, there should be a path to exit. This installation may violate commonly accepted construction practices. The potential consequences of improper stucco installation could be trapped moisture and long-term decay, cracking, etc. which may not be revealed until years in the future. We suggest that you obtain an independent evaluation of the installation methods by a certified stucco specialist (AWCI or EDI certified). And we caution you against relying solely on information provided by the builder or stucco installer. Here is a video for your information:

I like the mirror trick!
