Snow accumulation on flat roofs can pose a safety problem, as the weight of the snow can exceed the safe carrying capacity of the roof. Water accumulated as snow melts can also cause leaks. Hand-shoveling snow off the roof is one of the few options available if the snow load on a flat roof reaches an unacceptable level.
Flat roofs can cave in under the weight of built-up snow. Slanted roofs typically are less of a concern because the snow falls off and the pressure is not much of a worry. Cleaning snow off a roof can protect the roofing system and building from damage caused by excessive weight load. It is important to remove snow after a heavy storm to keep the damage to a minimum.
Gather 1 cubic foot of snow, melt it and weigh the water. If the water in 1 cubic foot of snow weighs 4 pounds, for example, and there is an average snow depth on the roof of 2 feet, the average load on the roof is 8 pounds per square foot.
