Kasey Palmer’s first league goal in Rovers colours was enough to earn the points on a sunny afternoon at Ewood Park.
The Chelsea loanee struck early in the second half to earn what was a just about deserved victory for Tony Mowbray’s men, slamming home from close range after Daniel Bentley spilled an Elliott Bennett cross into his path.
The hosts produced a disciplined defensive display throughout the game and in the end nullified Brentford’s rare forays forward.
The result pushes Rovers further up the table and continues our unbeaten run this term whilst adding a first home victory of the campaign.
Mowbray made two changes to his side from the one that started against Reading in midweek, with Joe Nuttall and Palmer coming in for Danny Graham and the injured Adam Armstrong.
Brentford made four changes from their midweek draw at Aston Villa with Neal Maupey out through suspension and Sergi Canos, Josh McEachran and Lewis MacLeod all on the bench. Nico Yennaris, Kamohelo Mokotjo, Marcus Forss and Said Benrahma.
It was an even start to the game, but it was the returning Forss who had the first opportunity of the game 12 minutes in but his strike was straight down the throat of David Raya.
Up the other end, Joe Rothwell weaved his way into the box before seeing his left-footed curling effort deflect just past Bentley’s right-hand post.
It was a great tactical battle between the two sides and after the half hour the visitors hit the bar. A dinked ball from the right found the head of Benrahma, who clattered Raya’s upright just after the half hour mark.
Rovers responded a moment later when Nuttall glanced a header into the arms of Bentley before the highly-rated Ollie Watkins let fly but saw his attempt whistle just past Raya’s right-hand post.
The hosts improved after the break but it was Brentford who went close again as Nico Yennaris slammed a curling effort onto the bar before Rovers earned the opener seven minutes into the second half.
A superb ball from Rothwell switched the play from left to right and freed Elliott Bennett, whose low ball in was tipped away by Bentley but only into the path of Palmer who rifled home to put Rovers a goal up.
The game was getting stretched and Benrahma saw an alert Raya in the way of a dipping 30 yard effort to tip around the post.
Time was running out for the visitors to get an equaliser and Watkins drifted a shot well wide of target after Romaine Sawyers' pass in from the right.
In the dying embers of the game, Rovers were thankful to see Lewis MacLeod’s ferocious strike dart a yard or two past Raya’s post but that was to be the last notable action of the game and Rovers ran out winners.
