Gatiss wrote 'The Unquiet Dead' and 'The Idiot's Lantern' for previous series, while Roberts penned 'The Shakespeare Code' and 'The Unicorn and the Wasp', and also co-wrote 'Planet Of The Dead'.
The show composer told musicfromthemovies that his own approach would alter because of the exit of David Tennant from the lead role and replacement of showrunner Russell T. Davies with Stephen Moffat.
Gold said: "In all honesty I make refinements anyway, when I score Steven's episodes, because they do come at the story from a different angle.
"I don't know if you can even talk about a single approach, musically, to all of the episodes as they've been done so far - there's a different approach to each one - and that'll be the same again."
He added: "I mean with Mark Gatiss and Gareth Roberts and people like that writing episodes, you know what their episodes are like from previous series.
"So it's going to be that, with Steven's comments, and Matt's performance are going to be different and they might be different in structure somehow... every episode might not involve so much running down corridors! I don't know."
Gold also confirmed that he has "been working" on an update of the show's opening theme music.
