Our brick chimney is leaning away from our house. The breast is in the living room, pretty much flush with the wall. The backside starts in the attached garage, goes through its roof and up past the second floor house roof.
We are thinking of removing it to below the garage roofline so we don't have to deal with the living room at this time. We also have a metal roof very much like this but not as steep:
The chimney basically goes through the peak of the garage roof, although not quite centered.
I expect we'll need a roofer and someone else to patch the vinyl siding (there is none where the chimney used to be against the house.
What kinds of things should I expect? Cost (understood to be very general), approach (hopefully not throwing the bricks down the chimney), damage to roof besides closing the hole, or anything else to watch out is what I'm after.
