Bishop Fenwick High School in Peabody was also closed yesterday in part because of concerns about too much snow on its big, flat rooftop.
"I was concerned this morning, and I wanted to have it checked out to make sure it was safe," said Sister Cathy Fleming, the school principal.
Upon inspection, the building actually only had about a foot-thick layer of snow.
"It's unbelievable. I think it was probably the wind that blew it off," Fleming said. "We have people up (on the roof) right now blowing it off, so it shouldn't be a problem."
Also in Peabody, the Workout World fitness center's snow-covered roof was being assessed yesterday afternoon by the building inspector and firefighters.
