Right so this kind of thing always gets me because dogs are genuinely one of the best early warning systems we have. They pick up on infrasound, air pressure changes, scents we cant detect - there's loads of scientific backing for why they freak out before or during something weird. Your dog refusing to go out until morning is the detail I'd be focusing on, not even the sounds.
What did it sound like footstep-wise? Like was it a rhythmic walking pattern or more random scrabbling? That distinction matters a lot because foxes and cats get on roofs all the time and they sound absolutely mental up there, way louder than you'd expect. But if it was paced and deliberate that's a different conversation.
Somerset here and I've heard some weird stuff around the older farmhouses at night. Acoustics in rural areas do strange things. Would love to know more about where you're located and whether theres any history with the property.
