When I presented to the builder that the gaps should be sealed or caulked underneath the 2nd Story bump out, the builder replied no, you would never seal those gaps because the gaps are supposed to be there, because that is your drip edge if water were to get behind there it would need a place to drain.
Note that the second story is wood frame, not block. I have never heard of a drip edge made for wood.
Can someone help in terms of who is right and what needs to be done if anything?
