After Raphael's death, Raffaellino continued working in the Vatican, helping complete the Sala di Constantino though now under the direction of Giulio Romano. After the 1527 Sack of Rome, like most of Romano's studio and most of the foreign art community, Raffaellino and other artists dispersed through Italy, most returning to their home cities.

He also worked in Borgo San Sepolcro. He worked for the service Duke Della Rovere in Urbino from 1539 to 1543. He also worked with Girolamo Genga, decorating the Camera dei Semibusti, Sala della Calunni, and Cabinet of Hercules of the Villa Imperiale of Pesaro for Francesco Maria I della Rovere, Duke of Urbino. In Perugia, he worked at the Rocca Paolina (1540). In 1536, Vasari commissioned from ephemeral street decorations based on the occasion of the entry of Charles V into Florence.
