Heavy snow, ice storms and extreme cold can cause severe property damage and also put human and animal lives at risk. Accurate predicting of winter storms can help people prepare by making sure they have adequate fuel, food and other supplies on hand, but an unexpected change in wind direction can result in major snow accumulation in a localized region. In New York, this is often referred to as lake-effect snow because it generally involves geographic areas near Lake Erie or Lake Ontario.

Snow loading, the downward force exerted on structures by the weight of accumulated snow, may result in damage to roofs or the actual collapse of the roof itself. In addition to snow accumulation there are other conditions that may contribute to snow loading problems and the potential for roof collapse:
(1) adding insulation to the roof without ventilation may cause condensation & eventual rotting of the rafters or deck;
(2) re-roofing with three or more layers of shingles;
(3) not correcting observable symptoms of structural problems.
