Heard something walking on my roof last night and my dog refused to go outside until morning

Interesting one. The dog behaviour is actually more compelling to me than the roof sounds - animals don't perform for an audience, do they.

A few questions worth considering before you file this under ". Paranormal":

What's your roof material? Slate and old tile can expand and contract massively overnight, especially with temperature drops. Sounds remarkably like footsteps., Any large trees nearby? Squirrels, foxes, even cats can create surprisingly heavy-sounding movement up there., What breed is the dog, and has it refused to go out before? Some breeds are genuinely more attuned to infrasound than others.

That said - I've been doing EVP work and site investigations around the North East for the better part of 20 years, and I've learned not to dismiss the animal response angle too quickly. Dogs picking up on something before any audible event is documented often enough to be worth taking seriously.

What I'd suggest: get a decent audio recorder outside tonight. Even a basic Zoom H1n left running will capture frequency ranges your ears miss entirely. If whatever it was comes back, you'll at least have something to work with rather than a memory.

Also - purely out of curiosity - any history with the property? Previous occupants, local folklore, that sort of thing? Context matters enormously with these reports and people always forget to mention it.

@WhitbyLurker dog behaviour is genuinely one of the better indicators we have. No agenda, no wanting to seem interesting on a forum.

Worth noting though - what kind of dog matters. A border collie refusing to go out hits differently than a labrador that's scared of carrier bags.

The roof thing I'd actually want to rule out before getting excited. Foxes up there are more common than people realise, especially in built-up areas. Had something similar years ago, turned out to be two foxes having a domestic on the guttering.

Key questions:

Single animal sound or multiple?, Any smell associated with it?, What's the surrounding terrain like?

The smell question gets dismissed but it's crucial for anything Bigfoot-adjacent. Classic musky/sulphur combo is a consistent data point across hundreds of documented encounters.
