Needing reconstruction, use photo for roof (8)

I believe the answer is:

housetop

I'm a little stuck... Click here to teach me more about this clue!

'roof' is the definition.
(housetop is a kind of roof)

'needing reconstruction use photo' is the wordplay.
'use photo' can be anagrammed to 'HOUSETOP'.
However, I am unsure how this is indicated.

'for' acts as a link.

Can you help me to learn more?

(Other definitions for housetop that I've seen before include "[PROCLAIM] from up here?" , "Roof (from which to shout?)" .)

I've seen this clue in The Times.
