Another funny thing about snow load. You can cause a building collapse due to an issue referred to as Unbalanced loading. If you clear off the roof on one side of a main rafter where you have significant rafter to rafter spacing, you can have the roof fail or tear apart because there is now zero load on one side and the purlins or stringers will act like a teter-totter.
Saw a guy collapse his roof dock roof that way.
I never thought about that. Yeah, you’re right. An unbalanced load like that can do some major damage.
