But they were pegged back on the half-hour mark when Dale were awarded two penalties in quick succession. First, Michael Rose was brought down by Sam Morsy but George Donnelly's spot-kick cannoned off the woodwork.
Yet when Rochdale worked the ball back into the box, goalkeeper Tommy Lee was adjudged to have fouled Scott Hogan, paving the way for Andrew Tutte to convert from the spot.
Hogan then fired Dale into the lead with a fine individual goal in the 51st minute before Roberts levelled things up when he raced on to Jimmy Ryan's throughball to lob Josh Lillis.
Hill echoed Spireites counterpart Paul Cook's enjoyment of the contest and having blasted the match officials last weekend for sending off Peter Cavanagh seven minutes into the defeat at Burton, this time he felt they were spot on with key decisions.
"It was a superb game, fiercely contested and it had the feel of an end of season game where two teams are vying for promotion," he said.
"Both penalty calls were correct, we cannot argue about that. There was nothing crazy about it except reactions and the furore of the supporters and, let's be right, the opposition's bench and their players.
"But that's football, it's part of the kidology and the psychology of trying to get at the referee. But they were both correct and we missed one and scored the other.
"It was a really entertaining game and one I will watch back with no boredom."
