I have a project to build an addition to an existing building. The existing building has two sections. The first section is 329 feet long and 16 feet tall. The second section is 20 feet long and 10 feet tall. The new addition will be 75 feet long and 18 feet tall and will be adjacent to the lower existing roof. All of these roofs are flat. I'm trying to determine the snow drift on the lower roof section.
The leeward drift onto the lower roof from the 329 foot section will be 24 feet long, so it will truncate against the new addition. Since there will also be a windward drift against the new addition from the same wind direction, I was going to have the leeward and windward drifts intersect on the lower roof.
Is this a reasonable approach?
