Wind noise and wind caused noises in buildings include these common mechanisms. In addition regardless of whether there is an attic or not we suspect that most of the wind noise is caused by wind moving through the attic vents. The wood sheathing could be rubbing against the trusses and you could be getting noise from wood rubbing against metal fasteners.
A loose attic vent or shutter on a window can make a banging noise in the wind. Air movement through building openings leaky windows gaps cracks in siding. Air movement over irregularly shaped building surfaces or attachments. This noise can get annoying but there is a remedy for it.
Heating ducts as they cool also make banging. By replacing the old flap with one that is weighted or has a spring you can stop the wind from opening the vent flap. As to what s causing the problem and the noise it s pretty simple. Air passing through ducts and radiators can sometimes create a loud noise as can water passing through pipes.
