Boston firefighters battled a two-alarm blaze on Monday night that started on the roof of an apartment building in Mission Hill near the Longwood Medical Area and displaced about 10 people, fire officials said.
Steve MacDonald, a Fire Department spokesman, said the blaze began on the roof of 27 Wigglesworth St. shortly after 10 p.m. and was declared out roughly 15 minutes later.
During that time, MacDonald said, apartments in the buildings at 27 and 29 Wigglesworth suffered mostly water damage, making all six units uninhabitable.
He also said no one was injured.
MacDonald said damages were estimated at about $500,000 and that the cause of the fire was under investigation. He said it was too soon to say whether investigators believe the blaze was suspicious.
MacDonald added that officials are trying to determine whether a grill, aerosol cans, or any other potentially combustible items were located on the roof deck at 27 Wiggelsworth.
A neighbor, John Dickson, 30, said he was on the third floor of his building when he heard a “popping and swishing sound” and saw people on the street running toward the building telling residents to call 911 and get out of the residence.
“They said no, you need to get out, the roof is on fire,” Dickson said.
He added that he could see the blaze next door as he and his fiancee were making their escape.
“I saw light from flames and could feel the heat from it,” he said. “We just ran out with nothing.”
Gabriel Colon, 23, said at the scene that he was subletting his third-floor apartment at 27 Wigglesworth to someone and was informed by property management on Monday night that there had been a fire at his residence.
He said he was informed that the roof was currently unstable and that apartments had suffered water damage, but he expressed relief that everyone had gotten out safely.
“Thankfully no one’s in there now,” he said.
MacDonald said 27 Wigglesworth will be uninhabitable for “a while” but it was not clear how long 29 will be closed off to residents.Globe Correspondent Nicholas Jacques contributed to this report. Travis Andersen can be reached at firstname.lastname@example.org.
