Retired minister with a roofed canopy (7)
I believe the answer is:
veranda
'roofed canopy' is the definition.
(architectural feature)
'retired minister with a' is the wordplay.
'retired' is a reversal indicator.
'minister' becomes 'rev' (short for Reverend, a church minister).
'with' becomes 'and'.
'rev' back-to-front is 'ver'.
'ver'+'and'+'a'='VERANDA'
(Other definitions for veranda that I've seen before include "Roofed terrace along the side of a house" , "Roofed platform level with the ground floor" , "Stoop" , "Sheltered terrace attached to a house" , "Roofed platform along the outside of a house" .)
