The snow load for this project seems a bit complex because the lower roof has a steep 1:2 slope, creating a deep valley where snow drift can accumulate. This setup differs from ASCE 7-22 Figure 7.7-2, where the lower roof is flat. Because of that, you ...

Consider a parapet for your new building to help keep the snow from that building from all being able to blow onto the adjacent building. Depending on where you are you risk failing the existing building's roof. ------------------------------ Sarah ...

Hi Darya, Thank you for the response. I was looking into that section of the code but wasn't sure if this was meant for my condition. So the unbalanced snow load for the valley (2pf/Ce) should be in addition to the roof drift based off worst case ...

Christopher, in situations like this a standard windward/leeward drift check often isn't enough. When a new taller structure creates a narrow valley next to an existing roof, it typically acts as a snow-trap, so you should also consider a valley / unbalanced ...

I am working on a project with an existing building that is 50'-0" wide, is a gable roof with a 6:12 roof slope. At the center of the roof there is an additional gable roof that extends 6'-0" tall. Essentially this is a 12'-0" wide gable roof over the ...
