Do a rush job on the roof? (6)

I believe the answer is:

thatch

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

'the roof?' is the definition.
(thatch is a kind of roof)

I don't understand the rest of the clue.

(Other definitions for thatch that I've seen before include "part of House?" , "Rural roofing" , "Cover for house" , "Traditional material for covering" , "Old fashioned rural roof covering" .)

I've seen this clue in The Globe and Mail.
