At these slopes snow creeps rather than slides and is easy to manage.
Others allow a 1 4 inch slope.
Snow and ice buildup can slide off a metal roof causing a dangerous avalanche effect.
However on the high end it could be over 40 pounds per square foot.
At the low end that might be on the order of 10 20 pounds per square foot psf.
Metal roofs leak under these circumstances.
