A roll over is a roller coaster element that starts as an immelmann and ends as a dive loop. It was first used on Vekoma's Suspended Looping Coaster in 1994. It was later used on Pinfari's Xpress inverted coaster. In 2020, Intamin put a roll over on Sandy's Blasting Bronco at Nickelodeon Universe.
It is similar to the sea serpent element.
