According to the chimney sweep, I must relieve my roof truss and move it away from the chimney, as it is directly in contact. But what about the roof boards, only the end is in contact, and someone once said that the end of the wood can be against the chimney wall. Does anyone know if that's true?
According to our chimney sweep, it is permitted to have end grain against the chimney in the fire protection regulations.
It depends on the chimney sweep and the municipality, my beams rest in the chimney... That's how they used to build before, and I was allowed to keep it that way when the chimney sweep was here and did a pressure test because it has always been like that. If it had been a new construction, he would have had other opinions.
I have the same experience, our house has a roof truss that is 2 cm from the chimney, but I didn't need to fix it for exactly the same reason as Dalbotös wrote. However, what I built new that needed to connect to the chimney, I had to follow today's requirements.
I managed to relieve the roof truss today; it was a "bängligt" job since it was cramped and not at all that simple. Since my roof has been renovated using the layer-on-layer technique, I'm wondering if you think all the wood needs to be removed. The chimney sweep commented on the roof truss that was leaning, but on top of the roof truss there was a batten, and on that, there were wooden shingles (the original roof was shingle). I managed to remove this batten and the shingles (it's a small space but I did it eventually), but it turns out there's a new batten on top of that for the old tile roof. I'm also afraid that on top of that, there's another batten for the current metal roof. This tile batten is not at all easy to remove. Do you think the dear chimney sweep will also comment on the batten? He did say "only" that I should relieve the roof truss. 
Can I get away with it?
