The 84-year-old actor had a tough time on the cobbles last year when Ken suffered a stroke in October, which left him partially paralysed.
However, Roache said when he first heard the news about Ken's fate, he worried he was being axed from the show.
"When Ken had a stroke it made me think about his mortality," Roache told the Sunday Mirror. "I got a bit worried they might be writing him out. Fortunately his recovery was quite quick."
Ken may still be recovering from the devastating effects of his stroke, but he's already causing all sorts of trouble for his sons in Corrie.
His recent conversation with Sinead Tinker had a devastating outcome for Daniel Osbourne, after Sinead had a secret abortion behind Daniel's back...
Viewers will see Ken struggling with his guilt over his comments to Sinead over the next couple of weeks.
And as for Roache's thoughts on how moving the show to six episodes a week will impact his work load, he's thrilled and oh so ready.
"I think six days will be seamless to us," he said. "We went from two episodes a week, then from four to five. It probably won't make much difference, hopefully."
Coronation Street airs weekdays on ITV.
