Angry smiles for roofing supplies (5-5)

I believe the answer is:

cross-beams

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

'roofing supplies' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'angry smiles' is the wordplay.
'angry' becomes 'cross' (cross can mean annoyed or angry).
'smiles' becomes 'beams' (beaming is a kind of smiling).
'cross'+'beams'='CROSS-BEAMS'

'for' acts as a link.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
