How can I attach roof beams to a wall?

I fully agree with . In my opinion, he is right. Even if it is a shed, there are still several things to consider like snow load, wind load........

Where is the problem in getting a carpenter to help who is familiar with this? It makes no sense to give advice when neither the location nor the construction method is known.

So 4 meters span with 160 beam is suitable for the snow load, and it has no wind load (it's a flat roof, right?).

And if anyone is underneath when it bangs or cracks, the wailing is loud.

Yes, it is a flat roof. Even if you ask a carpenter, it can collapse. And even then, the crying is loud.

Maybe I should also mention that the slope occurs over the short 4.68m width. I think such joist hangers, which are screwed to the wall, don’t work well there.
Oh man, I think I’ll just throw a tarp over it.
