NH fire marshal: Clean roofs of snow, beware of collapses
The Associated Press
CONCORD - With even more snow in the forecast for New Hampshire, the state fire marshal says there's a greater urgency to clear roofs of accumulated snow and ice.
Bill Degnan says a roof may collapse with little or no warning, and one common misconception is that only flat roofs are susceptible.
Degnan said signs such as sagging roof steel, leaks, cracks in walls and welds of steel construction and doors that pop open are warnings to evacuate, notify authorities, or contact a structural engineer.
Heavy snow was to blame for a partial roof collapse at an apartment building in Nashua on Wednesday night. The city received over 33 inches of snow in a recent snowstorm. There were no injuries, but all 30 units were evacuated.
