After leaving the military, Roache turned to acting. He appeared in various stage productions, then had uncredited roles in several films, and later won small parts in television serials including
Knight Errant Limited and
Skyport. He played the minor role of a space centre operator in the
Norman Wisdom film
The Bulldog Breed. Shortly before joining
Coronation Street at the beginning of the programme in 1960, Roache played the leading role in a
Granada Television play called
Marking Time, transmitted on
ITV in 1961. In an interview with the
Liverpool Post in 2007, Roache recalled "I played a young soldier in Germany who fraternised with a German girl, although I can't remember now how it ended. It was highly prestigious, though, and I have tried to hunt it down but there is no trace of it." He added: "But
Tony Warren, who created
Coronation Street, saw it and thought I was right for
Ken Barlow." On 16 October 1985, just weeks before the 25th anniversary of his debut on
Coronation Street, Roache appeared as the subject of TV show
This Is Your Life.
Ken and Me, Roache's first autobiography, was published in 1993, covering his life on and off screen. In 1999, Roache was the recipient of the
British Soap Awards Lifetime Achievement Award for his role as Ken Barlow. In 2003, Roache appeared on

Perry Como singing the song "
Catch a Falling Star". In September and October 2005, he appeared as a celebrity contestant in ''
Ant & Dec's Gameshow Marathon. He was the winner of The Golden Shot (a remake), progressing through to Bullseye in which he was beaten by television presenter Vernon Kay. He later entered All Star Family Fortunes'', hosted by Kay, but lost by two points to his competitors. Roache's 2008 autobiography
Soul on the Street contains a substantial amount of philosophical content in which Roache affirms his belief in the afterlife. In October 2008, he revealed on
BBC Breakfast he had had a two-year feud with actress
Pat Phoenix, a fellow
Coronation Street player, during which they did not speak to each other: this stemmed from her changing a scene involving the two of them. However, they did reconcile and became good friends. In 2010,

Coronation Street, was published to coincide with his 50th year playing Barlow. On 13 April 2012,
