While on approach to Runway 24 at ROA we received an EGPWS caution for terrain appeared. An EGPWS caution for terrain appeared along with an audible terrain. ROA Approach assigned an altitude of 4;000 ft. prior to clearing us for the visual approach 24. Setup to intercept final approach course south of HIBAN intersection and north of WUDAG. While on base leg with gear retracted a ground proximity warning caution appeared and disappeared immediately. A climb was initiated to comply with caution and message disappeared we presumed it was erroneous. The descent rate was arrested right as the message disappeared. Visual approach separation from all terrain was constantly maintained. Request full RNAV approach day or night to Runway 24 and ensure Roanoke Approach provides an adequate vectoring altitude.
Air carrier First Officer reported receiving a Enhanced Ground Proximity Warning on arrival into ROA airport.
