Recently installed new construction windows - removed the old windows down to the rough in, wrapped the entire rough in in protecto wrap (our far enough to cover where the nailing fin stops), dropped the new window in, covered the nailing fin with more protecto wrap and applied 3.23" vinyl casing/mold around and caulked. But they are leaking between the rough in and what appears to be the fin. Leak appears to be from the top but I have to assume that the sides will be vulnerable as well. Only caveat is that I could not remove the shingles to load the new window. The fin is screwed directly through them and into the house. They are the original asbestos shingles and could not easily be removed. A window contractor suggested this approach. As soon as it stops raining, I plan to pull the casing, apply a wider (as close to 4" as I can get - probably closer to 3.5) layer of protecto wrap, affixed with that manufacturers suggested spray tak, lay down a thick layer of silicon caulk, reset the casing around and then caulk the daylights out of that. Does this sound like a viable solution? If not, any reasonable suggestions that will get me to spring would help.

I have an old wooden front door with beveled glass. The door will not stay shut because the little thingy that goes into the catch doesn't come out far enough to stay latched. As you can tell by my vocabulary of technical terms, I have no idea how to fix this
