Roger foi revelado pela Ponte Preta, onde jogou durante três anos, antes de ser contratado pelo São Paulo. Neste clube, como reserva, foi campeão da Libertadores de 2005. Foi negociado com o Palmeiras ainda em 2006, quando a diretoria do São Paulo trocou o jogador pelo lateral Lúcio. No entanto, não teve sucesso e acabou voltando a Ponte Preta em 2007, para a disputa da Série B.
