Horizontal paneling and no flashing, common mistake?

[Klicka]

Shouldn't you always have flashing? I've seen several instances where horizontal paneling has been installed and the window trim lacks flashing.

Couldn't water run down, right?

Can and kan?
I don't have any överbleck. But (almost) all the windows are with the top edge under/inside the eaves, so it would probably take a lot for it to leak in.
However, when I "have time" I'll apply a bead of acrylic sealant along the top edge of the överfodret.

But KoW, on that gable window, you should have an overbleck, right?

I am lying around and haven't put on any windows yet for the same reason as KnockOnWood.

However, I have considered putting them on the gables and those that are really far down from the eaves (e.g., above the garage doors which are one floor down).

But KoW, for that end window, shouldn't you have an over-flashing?

What you see is just the garage.
But yes, that window, and a couple of others on the house gables, will get a round of acrylic sealant on the top edge of the trimming.

But there will be no flashings.
Keep in mind that a horizontal, rebated panel is much tighter against rain than a vertical board-and-batten panel,
which apparently leaks like a sieve when it has dried apart after a few years.

The horizontal panel is tight during driving rain, unlike the vertical one.
Look at the houses in the Norwegian Sørlandet.
There, horizontal paneling is very common, and it's from there that I've drawn my inspiration
