Two cars were damaged after winds blew a felt roof from the top of a three-storey office building.
Beauchamp Avenue in Kidderminster, Worcestershire, was cordoned-off for about an hour from 13:00 GMT while firefighters made the area safe.
They were sent to the roof to secure other loose pieces of felt, before isolating the gas and electrics.
One car had a cracked windscreen while the other had scratches to its paintwork.
