His popularity, originally in central and northern Italy and at Montpellier, spread through Spain, France, Lebanon, the Low Countries, Brazil and Germany, where he was often interpolated into the roster of the Fourteen Holy Helpers, whose veneration spread in the wake of the Black Death.
The 16th-century Scuola Grande di San Rocco and the adjacent church of San Rocco were dedicated to him by a confraternity at Venice, where his body was said to have been surreptitiously translated and was triumphantly inaugurated in 1485; the Scuola Grande is famous for its sequence of paintings by Tintoretto, who painted St. Roch in glory in a ceiling canvas (1564).

We know for certain that the body of St. Roch was carried from Voghera, instead of Montpellier as previously thought, to Venice in 1485.
Pope Alexander VI (1492–1503) built a church and a hospital in his honor.
Pope Paul III (1534–1549) instituted a confraternity of St. Roch.
This was raised to an arch-confraternity in 1556 by Pope Paul IV; it still thrives today.
Saint Roch had not been officially recognized as yet, however.
In 1590 the Venetian ambassador at Rome reported back to the Serenissima that he had been repeatedly urged to present the witnesses and documentation of the life and miracles of San Rocco, already deeply entrenched in the Venetian life, because Pope Sixtus V "is strong in his opinion either to canonize him or else to remove him from the ranks of the saints;" the ambassador had warned a cardinal of the general scandal that would result if the widely venerated San Rocco were impugned as an impostor.
Sixtus did not pursue the matter but left it to later popes to proceed with the canonization process.
His successor, Pope Gregory XIV (1590–1591), added Roch of Montpellier, who had already been memorialized in the Holy Sacrifice of the Mass for two centuries, to the Roman Catholic Church Martyrology, thereby fixing August 16 as his universal feast day.

Numerous brotherhoods have been instituted in his honor.
He is usually represented in the garb of a pilgrim, often lifting his tunic to demonstrate the plague sore, or bubo, in his thigh, and accompanied by a dog carrying a loaf in its mouth.
The Third Order of Saint Francis, by tradition, claims him as a member and includes his feast on its own calendar of saints, observing it on August 17.
