Honours even in Greater Manchester
Town were forced to settle for four points over the Easter weekend after being held to a goalless draw at Crown Oil Arena.
Alan Judge went closest to breaking the deadlock while substitute Josh Harrop was denied by a last-ditch tackle in the second half as neither side could find the breakthrough.
Paul Cook made one change to the starting XI from Good Friday's victory over Bristol Rovers, Troy Parrott replacing James Norwood.
Myles Kenlock and Oli Hawkins returned to the bench as Freddie Sears dropped out of the matchday squad.
The first half-chance of the game fell the way of Town after Teddy Bishop's cross was only cleared as far as Judge but the Irishman couldn't keep his half-volley down from the edge of the D.
An in-swinging corner from Andre Dozzell caused problems on 20 minutes but Luke Woolfenden's off-balance shot couldn't make it through a sea of bodies in the penalty box as the hosts cleared.
Town went closest to the opening goal just over 15 minutes later, Judge firing narrowly wide of the bottom corner from 25 yards.
Kayden Jackson was inches away from latching onto a loose back pass from Jimmy Keohane late in the half but Dale 'keeper Jay Lynch was alive to the danger and cleared.
Blues were left frustrated as the referee blew up for a foul on Judge early in the second half with Bishop looking to play advantage and running into the box. Dozzell went for goal from the resulting free-kick, curling wide of the bottom right corner.
Rochdale pinched possession deep in Town territory as they looked for an opening 10 minutes after the restart but Jake Beesley's pullback across the face of the goal was cleared by Stephen Ward before it could reach Keohane at the back post.
Cook's side were denied a big claim for a penalty on the hour mark after Parrott had appeared to have been bundled over by a combination of Eoghan O'Connell and Haydon Roberts on the edge of the six-yard box.
A break from substitute Armando Dobra nearly carved out an opening that Town needed with just under 15 minutes remaining. The Albanian sprinted 50 yards before playing the ball to Jackson on the right of the box. His drilled cross found Harrop but the ball was cleared by Keohane before the Preston loanee could get the decisive shot off.
Woolfenden was in the right place at the other end to clear the danger after Matty Done had skipped past a couple of defenders to reach the byline.
Harrop was booked late on for a trip on Ollie Rathbone in the middle of the park.
