The leg of the trampoline came through a bedroom ceiling in Moonah, but no-one was injured.

Jenny Pritchett said she woke up about 2:30 am to hear her adult son yelling.

"It was very scary actually at first because if it had gone further through, it could have done a lot more damage, especially to my son," she said.

"Something coming through the roof at you is quite scary, so it's still solidly wedged up on the house, sideways on the house that's where it will probably stay till someone comes and removes it."

She said her adult son was lucky to escape injury.

"It could have been a lot worse if had gone further through the roof and ceiling and hit my son because he was laying in bed covered in ceiling dust and [insulation]" she said.

"Trampolines are not a very good thing in the wind."

Ms Pritchett said a shed from the same neighbour's property also became airborne.

"The neighbour down the back also had had shed from next door fly into her yard and it also crossed another fence and damaged a car," she said.

Power being restored

This morning, almost 4,000 people were without power after lines were brought down in the greater Hobart area and at Sorell, but that has since reduced to about 1,500.

Goulburn Street Primary School in West Hobart is closed after part of a roof blew onto Forest Road.

Mark Dance from the SES said the damage has been extensive.

"They've varied from garage door blown in to the trampoline on the roof," he said.

A severe weather warning has been downgraded, but gusty winds are expected to continue throughout the day.

Mr Dance said volunteer crews would remain on standby.

The SES has reminded people to secure outdoor items and beware of fallen trees and power lines.
