Born in Haedo, Buenos Aires Province, Zárate played most of his career for Club Atlético Vélez Sarsfield, representing the club in two different spells. He made his professional debuts in 1997, playing in only 17 Primera División games in his first two seasons combined.
Zárate moved to Spain in 1998, going on to remain in that country for the following four years, always on loan: he started out at Terrassa FC in the third division, joining Real Madrid Castilla in the same level the following year. His impressive scoring form prompted Real Madrid boss Vicente del Bosque to promote him to the main squad, and he scored three official goals for the club (one in La Liga and two in the Copa del Rey); between 2001 and 2002 he represented Ciudad de Murcia and its neighbours Real Murcia, respectively in divisions three and two.
Zárate played with Livingston in the 2002–03 season, still owned by Vélez. He netted twice on his debut in the Scottish Premier League, a 3–2 home win against Motherwell, and eventually proved instrumental as the Livi Lions retained their division status.
Zárate's last loan would be with Ittihad FC in Saudi Arabia. Again with Vélez, he scored 13 times in the 2004 Clausura Tournament, adding eight in the following year's Apertura. In the subsequent Clausura, Roly netted seven goals as his team won the national championship for the first time in seven years.
In the following years, Zárate played in Mexico for two teams, also representing Club Atlético River Plate without any impact. On 25 July 2009, he re-signed with Vélez on a free transfer after a period of trial, from Ecuador's Barcelona Sporting Club, but was released during that year due to injury to his spinal cord; he returned to training in early 2010 and, eventually, signed a new one-year deal.
For 2010–11, 32-year-old Zárate joined Club Atlético Huracán in the top flight, for free. At the end of the campaign, the side were tied with Gimnasia y Esgrima de La Plata for the second-to-last position in the relegation ranking, and thus needed to play a tiebreaker, losing it 0–2.
After his retirement Zárate became a football agent, representing Argentine striker Maximiliano Romero, among others. In december 2017 he arranged the transfer of Romero from the Argentine Vélez Sarsfield to the Dutch footballclub PSV.
