The harsh winter of 2015 is taking a toll on the roofs of New England.
At about 7:15 a.m. on Feb. 28, the Norwood Nuggets youth hockey team were filing onto the Metropolis Ice Hockey Rink in Canton, Mass., for practice when they heard a snap, followed by another. Immediately, a coach yelled for everyone to leave the ice and exit the building. About 15 seconds later, a portion of the roof fell.
