Roof edges (5)
I believe the answer is:
eaves
'roof edges' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for eaves that I've seen before include "what might constitute a hangover?" , "Section of roof" , "Roof's overhang" , "Overhanging part of roof" , "Overhang at edge of a roof" .)
