Hi Paul it is all over the floor, it happens in summer as well if we have any rain, its not water coming in anywhere, but like condensation, when ever its damp out it is inside as well Thank you everyone for all replies and answers given
Can anyone tell me as to when its wet/damp outside the loft floor is as well, and how to cure it, there are 3 foot vents all across front of loft at bottom and a 3inch gap all along top at back, sputnik is left partially open as well
