EPDM is stamped with the manufacturer and the thickness along the edges of the roll (and sometimes in the center field areas) as I recall. EPDM is 'usually' always black.
TPO is harder to identify as the labeling disappears into the white color (all TPO I've seen is white, some is white through and through, some is black underneath and white on top).
