The blaze — which was extinguished after a few hours — began at about 10 p.m. and quickly blew through the roof of the luxury estate on the tip of Long Island, according to The East Hampton Star.
The East Hampton Village Police Department took a photo of the home as the flames swelled from the attic.
The businessman and philanthropist was not home at the time of the fire, the paper said.
Perelman’s security staff was in the residence and called 911 to alert them of the fire.
Fire departments from Montauk and Southampton helped the East Hampton Fire Department put down the fire, the Star said.
No injuries were reported and officials were trying to determine the cause of the blaze.
