Icicles and freezing runoff may look beautiful—but often cause damage when water melts, refreezes, then expands creating "ice dams." These "ice dams" cause water backup, leading to leaks, and damage to the roof, gutters, façade and interiors.
When a fresh layer of snow covers your roof, the warmth from the house and varying temperatures will melt the snow and ice. Then, when temperatures drop the melt water refreezes and expands. The expansion causes cracks and fissures in your roof and can crack roof surfaces, ruin gutters, scuppers, roof flashing, drain boxes and downspouts.
Avoid roof ice damage to your building or home.
