School:Sir Winston Churchill Collegiate and Vocational In
Abstract:This experiment investigated why ice dams occur on some roofs during winter and the diagnostic properties of observed frost melt patterns on the roofs of storey-and-a-half houses. Heat loss patterns were measured on a model roof proving that ice dams are most likely to form above the knee wall.
