In a game played in scorching heat, Rolfe scored the equalizer in the 70th minute when he got on the end of Fabian Espindola's inch-perfect cross from the right wing to volley home from six yards.
Rolfe scored the winner from the penalty spot in the 81st minute after New England's Steve Neumann was adjudged to have fouled United substitute Miguel Aguilar just inside the box.
Revolution had taken the lead inside the first 10 minutes when Davies's deft left foot touch diverted a low cross from Lee Nguyen into the net off the inside of the post.
Davies, an ex United player, declined to celebrate his seventh goal of the season, a modern tradition of players who score against a former team.
Despite the loss, the Revolution remain second in the east, four points clear of third-placed Orlando.
