Roy made his first impression on the darts circuit at the 1998 Dutch Open by reaching the semi-finals. He made his World Championship debut in 1999 but lost his first match to Rod Harrington. His overall record in the World Championship was quite disappointing, winning just three matches in his first eight attempts – but four times he has reached the last 16.

His record in the other televised PDC major tournaments has been slightly better with quarter final appearances at the World Matchplay in 2000 and 2003 and also at the UK Open in 2005 and 2006.

Roy won his first PDC title in March 2004 by beating Wayne Mardle at the JR+Vauxhall Holiday Park 128 Plus Classic and in May 2004 he reached the final of the Antwerp Open, losing to Colin Lloyd. In the following March he took his first Pro Tour (non-televised) title at the North West Regional Final of the UK Open beating Ronnie Baxter in the final. He has reached two other PDC non-televised finals since – the 2006 Sheppey Classic (losing 5–6 to Colin Osborne) and the 2007 Welsh Players Championship, when he beat Phil Taylor in the last 32 before losing the final to Raymond van Barneveld. He avenged that defeat to van Barneveld the following month at the Irish Players Championship before losing to Adrian Lewis in the quarter finals.

In October 2008 Roy won his first PDC title since March 2005 with victory at the Scottish Players Championship event in Irvine, beating Denis Ovens in a deciding leg in the final with a 161 checkout.^[1]

In 2017, Roy qualified for the UK Open through the amateur qualifiers, maintaining his record of qualifying for every UK Open since the inaugural event in 2003. He is one of eight players to have qualified for every event.^[2]

Roy quit the PDC in 2018.
