Roy was a firm favourite during his time at St. Andrew's between 1950 and 1957.
He died yesterday (Tuesday 7 January) aged 87 of natural causes.
The 'Blue destroyer' as he was nicknamed by the fans, made 239 appearances and scored ten goals.
Roy, who originally hailed from Sheffield, joined Blues from Sheffield United in March 1950 for a fee of £8000.
He began his Blues career as a forward, but was soon switched to a left wing-half role, a position where he remained for the duration of his time in the second city.
He was well-known for his tough tackling style and hard work on the field. He also had a spell as club captain.
He was a key member of Blues' Divison Two winning side of 1955, but missed the 1956 FA Cup Final through injury. His absence was said to be a key factor in Blues' 3-1 loss to Manchester City.
The following year Roy actually joined City for a fee of £10,000. He later went on to play for Crewe Alexandra and Oldham Athletic, before finishing his playing days with Banbury Spencer in 1961.
After retiring from the game he moved to Lichfield and worked as a scrap metal dealer.
Roy is survived by his wife Jean, children Karl, Keith and Kim, as well as nine grandchildren and nine great-grandchildren.
