The 2002 Premiers, on home territory, outgunned the Bulldogs early, maintaining a 10 point lead for most of the match after leading 16-0 at one stage in the first half.
Man of the Match Adrian Morley led the Roosters� defensive domination in a bruising clash of the forwards.
Roosters coach Ricky Stuart said he was impressed with his side�s attitude.
�They�re a team that you can never turn your back on,� he said.
�I think with that sort of attitude going into the sheds we are going to be tough going into the second half,� he said after the match.
�It was good preparation for next week.�
The Bulldogs struggled to match the Roosters physically, and were undisciplined conceding a 4-1 penalty count against them at one stage the first half.
Former South Sydney winger Chris Walker scored two tries; his second after a Bulldog�s charge-down gave Ryan Cross a line-break before passing to Walker on the burst who ran 40 metres to score.
Earlier, the Roosters opened their account with a penalty goal to second-rower Craig Fitzgibbon.
The Roosters dominated their opposition early with four-man gang tackles close to the Bulldog�s line.
Roosters fullback Anthony Minichiello could have turned his side�s early domination into points after receiving a bat-back off a Roosters kick in the 4th minute.
But the Australian representative, in his 100th first-grade match, knocked the ball on with the try-line open and just metres away.
Likewise, Minichiello�s opposing number one, Luke Pattern, could have put his side in front early, but couldn�t handle an inside ball 10 metres out.
The Roosters compiled an early lead, with winger Shannon Hegarty completing an exciting attacking movement after an Adrian Morley half-break. Brad Fittler juggled a ball before passing to Chris Walker who in turn found Hegarty on his outside.
The Bulldogs had opportunities throughout the Roosters� domination, but bad luck and the Roosters� relentless physical presence hit them hard. Minichiello counter-punched Bulldog�s halfback Brent Sherwin�s attempted chip and chase, running 50 metres amongst Bulldog�s defenders that eventually led to a penalty goal kicked by Fitzgibbon.
The Bulldogs finally troubled the scorers when Mark O�Meley charged over with four minutes to go till halftime. The try came on the back of two consecutive penalties to the Bulldogs, giving the Bankstown-based club a sniff trailing 16-6 at halftime.
The second half saw two tries to Bulldog�s winger Matt Utai, but despite conversions from Hazem El Masri and an improved effort, it wasn�t enough to get close enough to the reigning premiers, the Roosters winning 28-18.
Bulldogs� halfback Brent Sherwin said his side could hold their heads up after a good effort. �It gave us a bit of a boost scoring before halftime,� he said. �We had to meet them at that intensity, the boys tried hard,� he said. �It was a long road�we gave them a good run for the whole 80 minutes�we look forward to next year.�
