A power outage in the Cummins area left 600 customers without power on Tuesday after windy conditions saw a piece of roofing lift off from a local business.
A large piece of corrugated iron roofing came loose after a large wind squall hit the area, sending the piece onto powerlines where it hung, cutting power to most of the town.
SA Power Networks spokesman Paul Roberts said power went out at 4.15pm on the 11,000 volt lines.
"Power was 100 percent restored at 5.50pm," he said.
"The crew removed a piece of roofing iron from the lines that caused the outage," he said.
It is believed the local business had damage caused to skylights and solar panels on the roof also.
