Played in front of almost 9,000 people at the Sydney Football Stadium, West Tigers appeared to have the better run of play late in the match, but were unable to convert this into points.
The Roosters celebrated the return to form of veteran fullback Anthony Minichiello.
Minichiello, who turns 29 in May, has had a tough last three years, playing just 25 games due to spinal injuries. But he showed his best form in some time when he barged over Tigers halfback Benji Marshall to score in the 51st minute for a crucial 16-6 lead.
Marshall otherwise had a stand out match at halfback. The Kiwi international put second-rower Willie Mataka across the line in the 67th minute to make it a four point ball game, and set up a nail-biting finish.
