Those sure are lightly built covered docks.

Not only that.... how smart do you have to be to get on top of a
roof... most any roof... with a leaf blower and make the snow hit the
ground?

Most of the structures around here are not built to take New England
style snow loads..... so the prudent property owner dispatches the
snow as necessary...

Even when designed by all applicable codes, or insurance company
standards such as Factory Mutual, roofs may see loads in excess of
design criteria. Just this last week, we dealt with a million square
foot facility that I worked on in Missouri that had accumulated very
wet heavy snow in excess of design loads. Thankfully, not enough to
cause a catastrophic event! I told them to turn the heat up in the
building as high as they could, let me know if more snow/freezing temps
were expected.
A few years ago in Virginia one of my structures had so much snow above
design criteria that in some places they had joist deflections right at
the limit. Conduit that they had going from machines up to the joists
was buckling! Ended up having them rent some snow blowers and get on
the roof and start getting snow off! THAT was a sleepless night for me.
