Something in the roof unsettled me: ie bat (3,4)

I believe the answer is:

tie beam

'something in the roof' is the definition.

'unsettled me ie bat' is the wordplay.
'unsettled' indicates an anagram.
'me'+'ie'+'bat'='meiebat'
'meiebat' with letters rearranged gives 'TIE-BEAM'.

(Other definitions for tie beam that I've seen before include "Roof rafters connector" , "connecting timber" , "It joins rafters" , "Horizontal support" , "Structural part of roof" .)

I've seen this clue in The Times.
