Hello,

I live in a Smålandsvillan and am about to put up wall panels on the upper floor. However, I've now discovered something that I'm not entirely comfortable "hiding," so I would like your comments.

There is a glue-laminated beam which (according to my interpretation) is meant to support the roof trusses' posts since there is no load-bearing wall underneath. The problem, however, is that the posts do not rest on the beam; there is a gap of several millimeters, and what holds the posts up are a few poor nails on the side between the glue-laminated beam and the tapered part of the post.

No problem now, but what happens on the day when there is a lot of snow? Will the nails get torn out, and will the roof trusses drop a few millimeters? I've also seen a crack that I point out in the picture, maybe there's a connection.

I'm considering "shimming," like hammering in some thin wooden wedges or something into the gaps to make it fit snugly.

Are there any issues with that?

Wooden beam structure with a highlighted crack and a 3-5 mm gap between the support leg and beam, indicating potential structural concern.
 
No, the nails will not wear out. The trusses moving a few millimeters will not be noticeable - There are larger differences than that due to the boards drying and shrinking at varying rates.
