Question:
We had a record snow fall in December (90") and then rain. All the snow slid off our 6/12 pitch roof and with it went our chimney (wood box around free-standing). We even had a cricket. Any source you can recommend for chimney design in snow country? The chimney is on the side of the house (we know - bad idea) and we have a Dovre Sunburst fireplace by Heatilator.
Answer:
I've never heard of this before...even in snow country. I was a carpenter for years- and I can tell you that NOTHING would make a properly constructed chase go down with the snow. Take extra care when rebuilding to:
1. Perhaps build a small "peak" into the flashing that connects the unit to the roof so falling snow would splay to the side of it (somewhat)
2.More importantly- use lag bolts or through bolts to attach the framing to the home- make certain that this framing is attached to structural members (top plate- rafters) of the home where it joins.
