After 356 games at Fitzroy and Sydney between 1982 and 1998, Roos lived in the United States and briefly coached their national team, before returning to Australia as an assistant coach at the Swans under Rodney Eade. When Eade was dismissed midway through 2002 Roos took over as caretaker. The side turned the corner under him, and despite Sydney's management trying to lure Terry Wallace to take over Roos won out after winning support from the club's fans.
In 2005 he led the Swans to their first premiership in 72 years, and they played another Grand Final the season after. He missed the finals just once more, and retired from coaching at the end of the 2010 season - a year in which the Demons handed him his biggest ever loss as coach to that date.
He continue working for the Swans as head of their Development Academy, and for the media until late 2013 when the Demons finally landed him as senior coach after a hunt which had begun when Mark Neeld was dismissed midway through the season. Roos was unveiled as coach on Friday 6 September, under an arrangement where he would appoint a senior assistant coach to take over when his term of two years (with an option for three) expired.
He later exercised his option for a third year, appointing Simon Goodwin as his successor, and took the team to its best record in a decade in 2016, winning 10 games and remaining a chance of a finals finish until the second last week of the year.
In 2020 he joined North Melbourne to help select their new coach, then stayed at the club as a consultant through 2022.
