As someone who plays both of these characters, I'd say Greninja wins the matchup.
Greninja can whiff punish, outspace and combo Roy well, and can edge guard him using back air, Substitute and Hydro Pump. Greninja also has the speed to keep up with Roy. While Roy's shield pressure is still relevant in this matchup, it isn't as relevant here unlike other matchups, as Greninja is almost never sitting in shield against him.
Roy has to play a bit more patiently than usual against Greninja in order to win. It really feels like an uphill battle for him. If you're Roy, down tilt is your best friend here.
My vote is Greninja 6 / Roy 4.
