Small cracks in the roof beams. Serious?

Hello everyone,

in my house, which is currently under construction, you can see small cracks on the roof beams.
I have attached photos of them.

Are these cracks serious, and should something be done about them? Or is this rather harmless and normal?

Regards
Jens

Since you are an Elektroingenör, this question is forgiven to you, because your profession is far from wood. Just so much. Normal, no worry be happyy.

Do not enter the house anymore, if at all, only with a helmet and visor!

Safety first!!!

PS: Solid wood always has a few cracks. There are design tables for this in timber construction. Your little crack is miles away from critical

My garden has gotten a few cracks. Hopefully, I don't fall in.

Haha, OK. Thank you, everyone, all right. :)
