Cascade High School is located in a mountainous region of Idaho where 2 to 3 feet of snow can regularly accumulate on the roof. With this tremendous snow load, failure of the external gutter system was inevitable. Most gutters cannot bear the weight of freezing water, let alone the force of shedding ice and snow. Snow accumulations on sloped metal roofs can pose significant danger to property and life. Upson Company asked LMCurbs, Longview, Texas, to assist in solving an ongoing snow retention problem.
