The Bulldogs (8-18 overall, 2-13 Southeastern Conference) led 25-21 at halftime and by as many as nine points early in the second half, 32-23 before the Gators went on a decisive 21-2 run. The Bulldogs were up 34-29 when Georgia's Levi Stukes made a layup with 13:51 to play.
Roberson, only 3-for-11 at that point, came off the bench and the Gators scored the next 15 points. A trey by Roberson gave them the lead for good at 35-34.
Roberson hit another 3-pointer and made a lay-up during the run, which ended when Stukes made a pair of free throws with 5:30 left. Stukes made another lay-up with 4:51 left, Georgia's first field goal in nine minutes and also the Bulldogs' final points of the game. Florida held Georgia to just four field goals in the second half.
Stukes scored 20 points for Georgia, which wound up 12-for-49 from the field, including 3-for-17 from 3-point range.
The Gators finished with a 5-3 record on the road in SEC play. Florida can match the best SEC record in school history for a 16-game schedule on Sunday when the Gators host Kentucky at 2 p.m. on CBS. Florida will be gunning for its seventh consecutive 20-win season in what will be the final home appearance for David Lee.
