As a child, Roark was initially a figure skater , but then switched to mogul skiing due to high training costs. In 1990 she became American junior champion, but was unable to contest competitions in the following two winters due to injury.

On December 15, 1994, Roark made his debut in the Freestyle Skiing World Cup and came in 17th place in Tignes . In the following years she only took part in a few races because of her studies. Her first full season was in the winter of 1999/2000. On January 30, 1999, she won her first World Cup race in Whistler , and her second the following day. In the end, she was able to win the dual moguls discipline ranking. It was almost three years before the next podium finishes.

In January 2005 she celebrated her third World Cup victory after more than five years. She won two more races in the 2005/06 season. In January 2008 she stood on top of the podium for the last time.
