Roost's footballing career had a late start, due to the Second World War, eventually making his League debut in 1948 at the age of 24. He previously played for Stonehouse in Gloucestershire where he was spotted by a Bristol Rovers scout, and he joined Rovers initially as an amateur on 10 September. He was awarded his first professional contract after less than two weeks in Bristol, signing on 23 September.
After making 177 League appearances for Rovers and scoring 49 goals he moved to Swindon Town in 1957, but he played just eighteen League games for them in two years and scored only three goals, all coming in a single game against Shrewsbury Town in December 1957. After an unsuccessful trial with Yeovil Town in 1959 he joined non-League side Minehead in January 1960 for whom he played 90 times in all competitions and scored 21 times before retiring in 1963.
