Snow drift geometry

Snow drift geometry

RE: Snow drift geometry

My bet would be invisible or just forget about the snow all together, it happens :)

RE: Snow drift geometry

(OP)
Sorry about that. I have now made the "invisible" visible by providing a link within the original post. That shows the complex situation between a mansard roof and existing structure.

RE: Snow drift geometry

Yup, The Moose would know!

RE: Snow drift geometry

Could be either. Depends on what the length of roof is upwind (left) to fetch snow off of. Also depends on how long the low roof is becasue that distance is what will give you the drift at the right side. There can't be a leeward drift at the right side.

RE: Snow drift geometry

I assume you are asking about the tiny sloped roof on the left side of your diagram and as to the extend of including this in your hc? If this is the case, I would say that it depends on how conservative you want to be.

I have architects install canted roofs on the back side of parapets that would help eliminate drift (at least in accordance with the code). I require these roofs to be pitched 6:12 and require the vertical section of the parapet hc<hb. It appears as if you you have a similar situation. If your roof was new I might be more conservative (why waste a bunch of time) than if it was existing and I was trying to get something to work.
