We regularly have noises from over our bedroom in the early hours.
I have established that it is not rodents, but assorted birds (mainly pigeons) scratching at the small clumps of moss on the concrete roof tiles to get at the insects there.
I put a mirror in the back garden, angled to show the roof from the bedroom window and you can see them pecking away in time with the scratching noises.

Never trust an atom - they make up everything !
