Hello!

I'm in the process of putting together a garage and now realize I've made a little mistake. I'm supposed to mount flashing on the short sides because I need to split the panel due to its length. I didn't think it through and have already installed the nailing strip for the vertical panel. I then mounted the flashing on top of the nailing strip. Of course, it should really have been behind the nailing strip.

See pictures:

As you can see, I get a "pocket" behind the sheet above the nailing strip.

My fear is that I might get water and birch seeds and debris that blows in under the vertical cladding, blows over the flashing, and settles on the nailing strip. It never dries and then it rots.

Are my concerns reasonable and the only right thing to do is to tear everything down, or am I just worrying unnecessarily? Ideally, any water should dry out with the help of the ventilated panel. I don't have a good sense of how much water might blow up behind the panel or how much infiltrates.

What do you think? If it were an easy job to tear it down, I would have done it, but the nailing strip is unnecessarily well nailed, so it's going to be a hell to get it off, plus I'll probably have to scrap all the flashing sheets.

Input please?

Best regards, Henke
 
There will be the same pocket behind every panel board, so it's probably nothing to worry about. You can add a similar nailing strip above the existing one to eliminate the pocket.
 
The sheet is miscut. That bend is not approved

Finnjävel, good idea! I'll do that, it's also a simple solution. Regarding the fold, it was me trying to be smart and make room for the upper board that was supposed to come down into that groove. Realized on the spot that it wasn't so smart, so it will be redone.
