Loud vibration noise coming from loft/roof space during windy conditions

[JG26]

Hi, has anyone got an idea of what might be causing a loud vibration noise coming from my loft/roof space during windy conditions?

I think your house is possessed.

Eave trays vibrating.

Underlay laps not secured and flapping

An aerial lashing kit has failed and your old TV aerial is wobbling in the wind?

Have you tried going up there? (into the loft)

+1 for Eave trays flapping. I have the same noise
