Gap in side wall of shed

[oellph]

Hi all,

We have quite a well built shiplap shed in the garden, however on the main wall about half way down one of the shiplap panels has pulled away from the one above it leaving a gap of around 3-4mm. When it rains this is causing some to leak inside.

What's the best way to fix this please? Should I try some sort of filler?

looks like the boards have bowed off. best way is to carefully prise them off and refix them.

Sorry, I'm a diy numpty would i have to do this with the whole side wall or just the affected board and a couple either side?

that all depends on how much overlap is between each board
in the height off the summer the minimum overlap between boards you want is around 6mm

op, seems to me that these must have buckled an awful lot to get like this:

I fear that you may have to take all boards above it off and relay the whole lot, possibly adding a bracing beam somewhere along the length (hard to be sure though)
