Could it be squirrels jumping from way above in the trees? Anyone experience this?
You might have 'flying squirrels' hunting a bug or acorn that was on your roof. Other squirrels only hunt in the daytime but flying squirrels are nocturnal. Or perhaps you have an owl hunting in the area.
Could be almost anything. By the time you get outside, your intruder will have heard you and taken off. If you're really curious, you could stick a 'game camera' up there to see what's 'thumping.'
