Brettski,I would be a little cautious wrt a chimney like JHAP's. Albeit a
beautiful application for where JHAP lives, where we live, the sheets of ice coming off that pitch might do considerable damage to it?
Why do you store sheets of ice on your roof?
Keep in mind I'm no chimney expert and like you said 40 where our place is in Northern California we don't get sustained snow on the roof. It will only snow once or twice a year (usually a inch or so) at our place and even then it doesn't last more than a day or so.
JHAP,Beautiful stove and chimney (reinforcements look awesome), and floor looks great too!!! That chimneys gotta be a breeze to clean, well thought out, nice clean application!
Thanks 40.
