Dimitrov had just held serve to start the match when rain began falling and the match was briefly suspended while the roof was closed. It had been closed for Maria Sharapova's earlier three-set win over American Lauren Davis, but it was re-opened for the start of the men's match Friday.
Ball boys and girls used towels to wipe off the court while Federer and Dimitrov took shelter under shades usually used to protect players from the sun.
After about a 15-minute delay, play resumed.
The rain has prevented play Friday on outdoors courts. Seven doubles matches have been postponed.

Sharapova served 16 aces but made 42 unforced errors, compared to just 34 by her 103rd-ranked opponent.
The No. 5-seeded Sharapova faces Swiss teen Belinda Bencic in the next round and could meet top-ranked rival Serena Williams in the quarterfinals.

He said after the match that after he got treatment, the wrist ''got better.''
The seventh-seeded Nishikori saved eight of 11 break points, including three at 5-3 in the third set when he was serving for a two-sets-to-one lead.
Belinda Bencic has become the first player to advance to the fourth round at Melbourne Park with a 4-6, 6-2, 6-4 win over Kateryna Bondarenko in the opening match Friday on Rod Laver Arena.

Bencic, the first Swiss woman to advance to the final 16 here since Martina Hingis and Patty Schnyder in 2007, will play either fifth-seeded Maria Sharapova or American Lauren Davis in the next round.
Tournament officials said play would not be possible on outdoor courts until at least 2:30 p.m., and the rain was still falling at Melbourne Park.
