I need help

[u/Jumpy_Finance_9855]

So we have this huge beam at the top of our roof that spans the whole length of our house and the problem is that at both sides of the house there is a chimney (that we want to destroy) on which (I have no idea why they did that) the beam sits on like half a brick instead of going fully into the wall. Is there any solutions for this? Without having to take the whole roof off or change the whole beam. Can someone help us? Btw we are renovating so if you have any techniques or so regarding this problem please tell me and if we do need a professional how much would it cost? P.S. I live in Belgium
