We have to get our city house roof shoveled, but it is more making certain it don't fall on top of someone.

It can also be structural. Depending on the elevation, my county mandates houses be designed to survive wind speeds up to 157 miles per hour and snow loads up to 545 pounds per square foot. That means a flat roof would have to be built like a parking garage floor, but a sloped roof can transfer that weight to the exterior walls, and an true A-frame directly transfers the load to the ground.
