At first, trouble and strife shattered tiles (7)

I believe the answer is:

titfers

'tiles' is the definition.
(titfer and tile can both informally mean hat)

'at first trouble and strife shattered' is the wordplay.
'at first' suggests taking the first letters.
'and' is a charade indicator (letters next to each other).
'shattered' indicates anagramming the letters.
The initial letter of 'trouble' is 't'.
'strife' with letters rearranged gives 'itfers'.
't'+'itfers'='TITFERS'

(Another definition for titfers that I've seen is " East End headgear".)

I've seen this clue in The Independent.
