Snow on roofs can give problems in the winter. Snow can melt on the roof from the heat loss from the building and the melting water can freeze on the overhang and give risk for ice dams. The rest of the water will drip and can form icicles. A model has been made for this process. Results of a parameter study are presented. A short overhang increases the risk for icicles. A long overhang reduces the risk for icicles but increases the risk for ice-dams.

Nyckelord: ice, snow, physics, roofs, climate
