He was Dean of Dunblane Cathedral from at least 13 April 1554, a position he may have retained for the remainder of his life.[1]
In 1572 he was minister of Whithorn.[2] He was elected to the bishopric of Galloway on the death of Alexander Gordon in 1575.[3] He got Crown confirmation to the bishopric with mandate for consecration on 17 September 1578.[3]
However, John Gordon had been chosen as successor by Alexander in 1568, 7 years before the latter's death, and John Gordon seems to have prevented Roger from taking up the position of Bishop of Galloway in practice.[4] Roger was called "pretended bishop" on 27 June 1579.[3] Roger never seems to have taken possession of the see.[3]
