The Insurance Institute for Business & Home Safety (IBHS) offers home and business owners valuable resources to reduce property damage due to freezing weather. Addressing winter weather risks now should help save both time and money in the future.
Having a roof collapse during the winter season can be catastrophic. To prepare a roof for winter’s abuse and avoid larger problems later, evaluate the risk of snow accumulation and estimate how much snow the roof can take. When evaluating, determine whether there is any existing roof damage that may compromise the roof’s strength.
According to the IBHS, melting snow tends to more quickly run off of steep sloped roofs with slopes greater than three inches of slope in 12 inches of horizontal distance. This type of roof is typically found on houses in northern climates. Ice and snow tend to more readily accumulate on low slope and flat roofs over porches, lanais or parts of a home that are next to a taller section of the house, especially during high winds.
