A comfortable evening saw the hosts take the lead after just 13 minutes, when Dodo's cutback found Rodrigo Taddei, who fired through a packed penalty area to score.
Roma continued to dominate proceedings and doubled their lead a minute before half-time, when Daniele De Rossi selflessly helped on Francesco Totti’s pass to Adem Ljajic, who finished with aplomb.
Totti, who put in a particularly sparkling performance, and Ljajic were on hand once again midway through the second half, combining to tee up Gervinho for Roma’s third.
In the day's other game, relegation-threatened Sassuolo claimed a vital point at home to Cagliari in a 1-1 draw.
The home side took the lead after 37 minutes when Nicola Sansone's perfectly weighted ball picked out Simone Zaza, who fired a left-footed strike into the roof of the net.
Agim Ibraimi stepped up to slot home the penalty, dealing a blow to the home side's survival bid and giving Cagliari boss Ivo Pulga something to smile about in the first game of his second spell in charge of the club.
