Light, fluffy snow on rooftops can act as a sponge for rain, which is in the forecast for Monday. The Massachusetts Emergency Management Agency offers these tips.
With rain and snow in Medfield's forecast for Monday, the Blizzard of '13 may not be finished wreaking havoc in Massachusetts. The Massachusetts Emergency Management Agency (MEMA) warns that fluffy snow piled high on roofs can act as a sponge, absorbing rain and adding additional stress to structures. Relatively flat roofs are particularly vulnerable, MEMA says. In other cases, roof ice dams have formed causing water build-up, leading to interior damage. These conditions can accelerate the snowmelt. To minimize the risk of over-stressing a building roof due to accumulated or drifting snow: Information from a release by the Massachusetts Emergency Management Agency (MEMA) was used in this report.
