The roof of a large two-story holiday home at Endeavour Avenue, Lilli Pilli has been blown off by gusty winds on Tuesday afternoon, November 26.
A Batemans Bay SES team was called to the job but it was such a big task they asked Moruya crews to help, a Moruya SES spokesman said.
The spokesman said he had never seen a tarping job this big in Moruya - 25 metres by eight metres.
He said the trimdek metal roof was attached to battens by roofing screws, before one length of roofing rolled up in the wind and was thrown off completely.
It then jammed between the adjacent house which caused damage to that roof too.
He said the other section rolled up "like alfoil" at the end of the house closest to the road, and was still attached by some roofing screws.
He said no one was home, and no one was hurt.
At about 6.30pm, two SES members were in harnesses attempting to detach the roofing so it could fall to the ground.
Another team was preparing tarps to cover the roof in case it rained.
Two teams from Moruya and two teams from Batemans Bay were at the scene, with a total of 10 volunteers.
