FRAMINGHAM, Mass. -- Snow buildup and subsequent heavy rain presents dangers.
"The rainy weather we are expecting, on top of the recent heavy snowfall, could present a threat for roof collapses, as well as localized street and basement flooding around the Commonwealth," stated Massachusetts Emergency Management Agency (MEMA) Director Don Boyce. "If not cleared off of roofs, the snow acts as a sponge, absorbing any additional sleet and rain, adding stress to structures. Flat, commercial roofs are most susceptible if they are not draining properly. Additionally, MEMA encourages citizens to clear storm drains in their neighborhoods to minimize local flooding problems from this run-off."
* In many other cases, roof ice dams have formed causing water build-up, leading to interior damage. To minimize the risk of over-stressing a building roof due to accumulated or drifting snow:
* Be on the alert for large accumulating snow build-up or snowdrifts on your roofs.
* If roof snow can be removed with the use of a snow rake (available at most hardware stores), do so. Use caution, as metal snow rakes conduct electricity if they come into contact with a power line.
* Try to avoid working from ladders, as ladder rungs tend to ice up. Snow and ice collect on boot soles, and metal ladders.
* Flat roofs can be shoveled clear, but only if it is determined that the roof is safe to stand upon. Exercise care when on the roof to avoid potentially dangerous falls.
* Flat roof drainage systems should be kept clear to minimize the risk of excess roof ponding in the event of subsequent heavy rainfall or melting.
