They have been beaten 32-12 by the Roosters at the Sydney Cricket Ground, after leading 12-4 midway through the first half.
The result leaves the Warriors' 11th on the NRL ladder, outside the top eight on points differential.
"They were a bit too good for us," Warriors coach Nathan Brown said.
"Even though we were in the game for longer periods than what it ended up, I still think we've got a way to go to catch up with those sides.
