Heard something walking on my roof last night and my dogs wouldn't stop staring at the ceiling

Classic signs tbh. The dogs reacting is the bit that stands out to me - animals pick up on things well outside human perception ranges, could be infrasound, EM fluctuations, all sorts.

Few questions before jumping to conclusions:

What time did it happen?, Any weather that night? High winds can do weird things to roof tiles, Did the dogs bark or just stare? There's a difference imo

The staring without barking is the more interesting response. Barking usually means they've identified a threat. Silent fixation suggests they're tracking something they can't quite categorise. Had my two GSDs do exactly that in the garden last March - dead silent, heads locked on one spot in the sky. Nothing on my RTL-SDR scanner at the time but I did pick up some odd RF noise earlier that evening.

Worth checking if anyone nearby reported anything. Apps like Mufon or even just local Facebook groups can be useful for cross-referencing.

Also - any chance you've got a dash cam or any outdoor cameras? Reviewing footage even without expecting anything obvious is worth doing. Sometimes you catch stuff in the periphery.

What part of the country are you in? Rural or suburban makes a difference to what explanations are more or less likely.

Don't want to hype it up but don't want to dismiss it either. What happened next morning - any marks on the roof, disturbed moss, anything like that?

@Kingy63 worth checking if there's a ley line running under or near the property before jumping to EM fluctuations. A lot of these animal behaviour incidents cluster around intersection points and people just never think to look at the geography first. There's decent mapping tools online now, not perfect but enough to give you a rough idea. What area are you in roughly?

Dogs staring at the ceiling is interesting but could genuinely just be a cat or a fox on the roof, worth ruling that out first before going paranormal. That said I've had my two collies do exactly the same thing in an old farmhouse we investigated near Taunton a few years back, no animal on the roof, nothing obvious - and the EMF reader was going mental in the upstairs bedroom. What kind of property is it, old or new build? Makes a difference.
