Hello, I am going to do a roof lift this summer and realize that the chimney needs to be extended by about 4m. The existing chimney is from 1939 and divided in an arch on the ground floor, unsure if the old construction can support an additional 4m of stone.
Can/may one extend an existing stone chimney with metal, to reduce the weight?

You must take down the existing chimney a little below the attic which you will lift into place (unless you have a special case).
I have just done this and assumed that it will be possible to put on a metal chimney
Possible mina here then

During my roof lift, I cut off the masonry chimney in line with the underside of the floor joists so that from the first floor it looked like the masonry part extended into the next floor.
I then attached a metal flange that was screwed and sealed to the masonry. After that, I mounted a steel chimney further up through the new roof.
I checked this with the chimney sweep who thought it was perfectly fine, and we conducted a pressure test before sealing it back up.
A positive effect was that the draft in the chimney increased, and now the burning works perfectly.

Yes, it's possible to bend chimneys, it will be a bit more expensive, said my supplier.
But the roof trusses might be placed so the chimney can pass by.
