The Jumbo-Visma rider looked unstoppable in the closing kilometres of the final haute-category climb (17.5km at 6.2 per cent), aided by teammates Sepp Kuss and Tom Dumoulin.
Nairo Quintana (Arkéa-Samsic) and Emanuel Buchmann (Bora-Hansgrohe) made tentative moves early in the final kilometre, but it was Roglič who took over and vaulted away from his fellow general classificiation contenders for his fifth victory of 2020.
"We all knew about the hard climb at the finish and we started to control the race from the beginning. The guys are really strong so they managed it perfectly and in the end, I was happy to be able to win this," said Primoz, who took the GC lead with the stage victory.
The stage included five categorised climbs across 135 kilometres. All five days of racing will feature summit finishes this week.
