The actor, who plays Ken Barlow on the ITV soap, prophesied that the apocalypse will not occur this December as some believe, but instead a "golden age" for humanity will be ushered in.
"The world will not end in 2012. But it will change dramatically," he warned Silent Voices, a spiritual, paranormal and metaphysical magazine.
"It is moving to a higher vibration and all who are open, ready and willing can move with her."
He continued: "This will be the golden age, when a majority will know that they are love and that they are spiritual beings.
"The earth will continue to cleanse itself while material and negative things will collapse and cease to be."
However, Roache rejected suggestions that his comments were rooted in any form of religion or belief system.
"I am not now, nor have I ever been a spiritualist," he said. "Understand we are all pure love, made in love, living in love. It is urgent to get this over. Time is running out."
Roache previously caused a stir when talking to the media by claiming that he had slept with about 1,000 women.
