After retiring from the NHL, Roy joined the Quebec Remparts of the QMJHL as vice-president of hockey operations; he also became the owner and general manager, and on September 29, 2005, he was named head coach of the team.

On May 28, 2006, the Remparts won the 2006 Memorial Cup, the top Canadian Hockey League (CHL) tournament, beating the Moncton Wildcats 6–2 in the finals (although the Remparts were only the runner-up in the 2006 QMJHL championship, they were able to participate in the Memorial Cup since the QMJHL champions were the host city—see Memorial Cup, 1983 to present).
Roy is the seventh coach to win the Cup on his rookie year, and the first to do so since Claude Julien with the Hull Olympiques in 1997.

On January 19, 2007, Saguenay Police investigated an incident involving Roy and co-owner of the Chicoutimi Saguenéens, Pierre Cardinal.
There were reports that Roy threw punches at the co-owner after he intervened in order to disperse a crowd of hockey fans that were blocking the Remparts' bus after a game between the two clubs.
A complaint for assault had been filed against Roy, who faced possible assault charges in the matter.
Montreal newspaper Le Journal de Montréal reported that Roy later apologized to the victim via telephone.

In a press conference following a Remparts game on January 21, 2007, Roy said that he was "suffering prejudice on the part of the media," and believed that he was not guilty of the incident.
He then questioned his future as head coach and co-owner of the team, even considering resigning from his duties.
On January 25, 2007, Pierre Cardinal announced that he removed his complaint against Roy, before Roy made a press conference about his future in the Remparts, where he announced he will stay coach and co-owner of the team.

On March 22, 2008, in Chicoutimi, Quebec, Roy was involved in another on-ice incident during Game 2 of a first-round playoff series against the rival Saguenéens.
Late in the second period, in which the Saguenéens were leading 7–1, a brawl started and Remparts goaltender Jonathan Roy, Patrick Roy's son, charged towards opposing goaltender Bobby Nadeau.
The younger Roy hit Nadeau numerous times despite Nadeau indicating he did not want to fight.
After knocking Nadeau down, Roy continued to hit him.
Roy then fought a second Saguenéens player before skating off the ice while holding both middle fingers up to the crowd.
Patrick Roy denied inciting his son to fight, despite video evidence showing Roy making a gesture towards his son while he was advancing towards Nadeau.
After investigation by the League office, Jonathan Roy was suspended for seven games and fined $500, while Patrick Roy was suspended for five games and fined $4,000.
The Quebec Ministry of Public Safety has launched a police investigation into the matter.
In late July 2008, Jonathan was charged with assault in Saguenay courts.

On November 21, 2008, Roy's other son, Frederick Roy, found trouble playing for the Remparts when he cross-checked an opponent in the head after a stoppage in play.
Frederick was ultimately suspended 15 games by the QMJHL for the incident, which occurred the night before Patrick Roy's jersey retirement ceremony in Montreal.

In May 2009, several unnamed sources reported that Roy was offered the head coaching position with the Colorado Avalanche.
He turned down the position, but expressed the possibility of becoming an NHL-level coach at some future date.

In September 2012, Roy started a new chapter in his successful career by becoming a permanent member of the French-Canadian hockey talk show l'Antichambre, where he worked as a hockey analyst.
He was reunited on the set with his former head coach, Mario Tremblay, the man in part responsible for his departure from Montreal.
