While the scoreline was slightly flattering towards the hosts, their sharpness in front of goal was much superior.
Adam Birchall’s diving header was cleared off the line by Nathan Stanton and the Bees striker twice forced saves from Tommy Lee.
Adam Le Fondre netted Dale in front from six yards after Gary Jones won a high ball in the Barnet box.
Rochdale’s second came four minutes into the second half. Jones was again provider, collecting Adam Rundle’s pass and playing the ball across the face of goal for Rene Howe, who slotted in from close range.
Kallum Higginbotham made the result safe in the 72nd minute tapping home after work from Howe.
