Repair to new roof is a bargain (3,3,3)

Ross

I believe the answer is:

two for one

'a bargain' is the definition.
(as in a two for one deal)

'repair to new roof' is the wordplay.
'repair' indicates anagramming the letters (letters are fixed or repaired).
'to'+'new'+'roof'='tonewroof'
'tonewroof' with letters rearranged gives 'TWO FOR ONE'.

'is' acts as a link.

(Another definition for two for one that I've seen is " money-saving offer".)

I've seen this clue in The Guardian.
