Snow drift adjacent building
Snow drift adjacent building
(OP)
we have a new building a story high than adjacent. Architect wants me to design a sloped roof in the shape of the drift on the existing roof to eliminate snow drift.
I have always believed this was not a real solution, but others have gotten away with it. I believe the drift still exists and sits on top of the new sloped section.
Does anybody know of a reference that would justify this approach?
I told him to get a snow melt system on the existing roof. (all same owner)

RE: Snow drift adjacent building
In the NBCC snow melt systems are recommended to be ignored due to maintenance issues.

Specifically, "to design a sloped roof in the shape of the drift" will not (necessarily) omit the drift.
The essential element is to omit the "hc" - clear height from low to high roof. See ASCE-7.
