A Plymouth family has been temporarily displaced from their home after a tree crane collapsed on their roof Monday afternoon, but the father of the 17-year-old girl who was home during the event said he feels relieved she walked away unscathed.

Andrew Forman said he and his wife, Lisa, had hired a company to trim trees on their Lisa Avenue property.

The arm of the crane was stretched over the roof of the house around 4 p.m., working on a large pine tree while 17-year-old Rebecca Forman was writing an essay in the first-floor kitchen.

That’s when she heard a large crash and ran to a bathroom, expecting to see a felled tree. Instead, one of the crane operators ran inside and told her that the crane had gone through her roof and she needed to get out.

“The boom came down to the roof and rested on the second floor ceiling. It opened up a trench in the roof as well as doing some damage to the second-floor bedroom,’’ Plymouth Deputy Fire Chief Michael Young said.

Young said the impact knocked down insulation and sheet rock. He described the damage as significant but not catastrophic.

Still, Forman said his exhausted family will likely have to live in a condo for a few months while the house is repaired. The 52-year-old father said the damage on his home was estimated at $200,000.

He said the second-floor bedrooms of Rebecca and 13-year-old Rachel were a mess, but he hopes the family can return to their house by his birthday in late February.

“I’d rather deal with this than a daughter in the hospital somewhere,’’ Forman said from a hotel room on Tuesday.

Forman said he is very proud of his daughter for staying calm under pressure. “She’s a pretty brave girl,’’ he said.

Large wrecking cranes had to be brought in early Tuesday to lift the tree crane off the house. They finished around 3 a.m., Young said.

The Occupational Safety & Health Administration is investigating the collapse. Young said preliminary information suggests a mechanical failure.

Forman said he is counting his blessings.

“Nobody was hurt, which is the great thing,’’ he said. “That’s the silver lining.’’
