When green building fails.
A 700-by-50 foot section of a roof over a parking area buckled on Feb. 13 at a garden pond construction and supply company in St. Charles, Ill., west of Chicago.

Mr. Beaulieu said that the area had received a record snowfall and then, two weeks later, temperatures climbed above freezing. “The collapse happened right at the beginning of the thaw,” he said, leading to speculation that ice on the roof might have prevented meltwater from draining off. “But right now no one really knows.”
Not to say that a roof garden can't work, but obviously this one didn't.
