I am having the chimney taken down and rebuilt on my house.
My chimney is quite tall in comparison with some others on my street. There does not seem to be a standard height in this area.

What is the minimum height the chimney needs to be above the apex of the roof? I have a gas fire with a gas flue if that makes any difference. :confused:

Don't quote me on this, I remember it used to be 24" from the highest point to allow for the snow thickness, others may know as it maybe difference now.

The plumbers on here may know
 
i would imagine the chimney top needs to be well clear of the ridge regardless of it's location through the roof. obviously the lower down the roof elevation, the greater amount of exposed brickwork and the sturdier the stack needs to be.

as masona has said, a minimum of 600mm above the ridgeline. the taller a chimney is the better the draw (applies mainly to real flame fires).
 
my chimney is about 18" above ridge then a short pot of say a 12".
This is a class 1 for a multi fuel stive. House and chimney built in 1977 with glazed pipe liner.
also depends on obstacles around the flue that nay affect the draft of course, mine pulls well but is 24 feet high

Thanks for the replys,
It looks like 2 foot above the apex it is then.
Thanks again,

i seem to recall from my college days (but this is vague as it was over 20 years ago) that the top of the stack has to be 1 metre above the roof or if coming out in the hip one metre on the vertical and 1 metre on the horizontal if you that makes sense
