Officials say heavy snow can lead to roofs collapsing
CONCORD - State officials are warning residents of the danger of roof collapse, with the third major snowstorm this month with up to a foot expected particularly in central New Hampshire.
The storm may dump a 12 inches of heavy, wet snow, which may be followed by rain in parts of the state, according to the Department of Homeland Security and Emergency Management (DHSEM).
The greatest snow accumulations are expected in interior portions of the state except for the North Country.
"Snow accumulations on flat roof commercial or institutional buildings pose the greatest threat," said Perry E. Plummer, DHSEM acting director. "We urge building owners or managers to monitor their buildings, ensure that roof drains are clear and to remove snow as soon as that can be safely accomplished."
He said homeowners also should remove snow from buildings using snow rakes from the ground. If roofs need to be shoveled, that should be done by contractors with the proper experience and insurance.
Plummer said building owners and managers should be sure to clear snow from building exits, gas connections and vents.
The winter storm warning posted by the National Weather Service remains in effect through Thursday afternoon. Plummer urged residents and visitors to monitor weather conditions via broadcast, Internet sources, or NOAA weather radio.
