At what point/height is guy-support required for a masonry chimney?
How high/wide can an unsupported masonry chimney be?
Are measurements taken from the ridge or eave side?
Any charts, codes, or other info would help.
This picture was thrown in as a joke.
Thanks in advance.

I don’t see anything wrong.
It hasn’t, like, fallen down or anything, has it?

If the roof ridge is more than 3 feet below it, that huge missing section could be considered an alternative for a rain cap…

I don’t think there is a requirement for support. I will check my code book. If I remember correctly if the chimney is that high it is supposed to come up through the roof wide and be corbelled down to a smaller size.

I just checked and the code says bracing is required if the height is greater than 11’ above the masonry part of the wall. code ref 9.21.4.5
