Hi folks.
I am about to rebuild the roof of an old stone cabin, and I will have to build the chimney at the same time.
I am going to install a woodstove and stainless steel pipe all the way up. The section above the roof line will be covered with stone, what will make it quite heavy, so I guess it will need to stand on a proper structure standing on the foundations, rather than standing on the roof itself.
Are there any cheap and quick way to erect the chimney supporting structure from the ground, even if it doesn’t look good? (I will cover it with stone or bricks afterwards)
Thank you in advance for your answers.

I am getting confused now. It would be best to state your whole situation in one post. In the other one, you mention rebuilding the chimney, now this post is about rebuilding the roof, and your question puzzles me.
Let's start with a little more description of the whole project and of what your background experience is. your climate location would be helpfull too.That way everyone responding can give more accurate information.
You definitely want the masonry structure to follow a direct load path to the ground with an adequate footer there.

Hi.
I decided to write two posts, as I wanted to keep the descriptions simple and people would read them. Also there were two different problems, but related to the whole rebuilding of the roof.
Here's the description:
The cabin is in the mountains of Northern Spain, where there is a lot of rainfall in Spring, snow in Winter, and quite high temperatures in Summer. Due to local regulations, I have to keep the original stone tiles on the roof, so I will need to create a proper structure underneath to provide waterproofing and insulation.
The new roof decking on which the stones will be laid, will be build of 50 mm ferrocement laid on 6mm rubber membrane. As the monolitic ferrocement roof should be bonded to the chimney, the chimney should be built before laying the cement layer. And that's where it comes the question of building a quick and unexpensive structure to support the outside part of the chimney. This chimney will be right at the centre of the cabin, just beside the main pillar that will support the ridge beam which will support the rafters.
My experience? I know about carpentry, so the structure shouldn't be a problem. But apart from laying bricks, I haven't much experience on masonry. And that's why I post the questions in here, in search of your expertise and advice.
Let me know if you want me to clarify any more aspects.
Thank you for your interest.

OK!Since this monoroof must bond with the chimney structure, it is quite different than any of the basic principles I normally follow. Perhaps if this thread stays alive somebody with experience in this sort of thing will pop along...I wonder what the local codes are that will prevail there regarding this. I have been answering in reference to my experiences in the USA.Fire, masonry, and heat perform pretty much the same around the world though, so the basic principles should apply.I am supposing that the flex SS liner encased in the rock wool should do a lot to separate the inner heat column from the exterior masonry chimney structure.

Hi again.
Oh well, they don't have to be bound, I supposed they had to for the sake of the waterproofing, so there are no gaps between them.
What would be your way of doing it?
About the regulations, let's say that it's a cabin in the mountains, so the regulations don't really apply as such... but at the same time I would like to build a roof that will last another 100 years.
You can have an idea of what kind of "tiles" cover the roof looking at http://casapollo.bajatec.net
Thanks.

cinder blocks down to footings.

I am not a big admirer of fake rock, but one of the few times I've used it was on a chimney that protruded from a second story roof. It eliminates all the headaches of carrying the load to the foundation, and most manufacturers have pretty good matches for any real stonework you have.
