Playing game number 150, Mitchell Pearce put in a stand out two try performance as the Roosters recovered from a disappointing opening forty to run away with an impressive victory.
In another positive for the club, young Samisoni Langi impressed as he stepped up from the Holden Cup competition to make his NRL debut.
It was the forwards however who made sure the club secured the two points with an aggressive opening to the second half, setting up plenty of space for the outside backs to weave their magic.
Jake Friend kick started the scoring for the visitors, weaving under the Tigers defence after a great offload from Sam Moa.
A misread in defence then helped the Tigers level the score, a clever pass setting up Tuqiri to score out wide.
Moments late a lucky bounce seemed to set up a try for Tedesco, only for the video ref to rule he had gone dead before grounding the ball.
The Tricolours then made the home side pay with a bit of Sonny-Bill magic, shifting momentum back in their favour.
Williams sprinted on to the ball from five metres out and carried defenders over the line as he wrested the ball down to make it 12-6.
The intensity increased after the try, with Luke O'Donnell involved in a scrap with Galloway before later being put on report for a lifting tackle.
James Maloney slotted a penalty goal after the siren to have the Tricolours up by eight heading in to the break.
Dynamic as always off the bench, Daniel Mortimer showed his elusiveness scoring a quick fire double after the break, including a determined effort which must have just reached a blade of grass, to have the Tricolours in front by twenty.
There wasn't' anything fancy about the Roosters next back line movement direct from a scrum.
Halfback Mitchell Pearce passed the ball to a flying Daniel Tupou who simply ran hard and straight, right through the heart of the Tigers defence to further extend the Tricolours lead.
Pearce began his 150 game celebrations soon after, throwing a clever dummy and showing a handy step to score a four pointer of his own.
A brilliant example of never giving up, saw Jennings put down a ball that looked dead for all money before Pearce leaped on a terrible pass from Benji Marshall to hit the fifty mark and seal the result for the Tricolours.
