Leading 8-0 at halftime after a converted Michael Jennings' try - the 100th of his NRL career - and a James Maloney penalty, there was little indication of what was to follow after the restart.
The floodgates were blown open by prop Sam Moa from close range, followed by a double from Anthony Minichiello and efforts by Jared Waerea-Hargreaves, Shaun Kenny-Dowall and Daniel Tupou in a 20-minute blitz.
Despite losing star prop Aaron Woods with a knee injury and Robbie Farah heading to the sidelines due to the flu that had affected him all the week, the Tigers finally showed some fight late in the game.
Chris Lawrence threw Minichiello into touch and, from the resulting scrum, debutant Jy Hitchcox ensured the Tigers avoided a first shutout at their spiritual home with a neat run and finish.
The Roosters still had the final say when Mitchell Pearce darted over after another bulldozing run from Moa, with Maloney adding his eighth goal of the night.
