Roger Brard entered Ecole Polytechnique in 1925 to continue with the Corps of Maritime engineers. With Henri Villat (1879-1972) as his mentor, he submitted a PhD thesis in 1929 on the theory of ship movement. During this time, he came into contact with Emile Barrillon (1879-1967). From 1932 to 1938 Brard stayed at the arsenal of Brest where he was involved in various prestigious French cruisers. He improved ship propulsion by a careful study of propellers, thereby accounting for the effect of cavitation. Among others, he was involved in the propeller tests of paquebot Normandie, which won the Blue Ribbon in 1935 as the fastest liner boat between Europe and America.
At the outbreak of World War II, Brard was appointed collaborator of Barillon at the National Naval Research Center. Brard succeeded Barillon's position in 1942 until retirement in 1969. Brard added in the early 1960s a computational center to his laboratory to profit of a combined experimental and numerical approach. He personally added to both the modern war and commercial French fleets, and was in particular active for the French prestige boat France. His main papers were published in the Bulletin de l'Association Technique Maritime et Aéronautique. In parallel to his position at the National Laboratory, Brard was appointed in 1942 professor of naval engineering at Ecole Polytechnique. He was involved from 1954 in the development of the French nuclear submarine fleet. From 1958 to 1962, Brard directed in addition Ecole Nationale Supérieure du Génie Maritime in Paris, and served as vice-president of Société Mathématique de France since 1946, taking over presidency in 1950. He was elected Member of Académie des Sciences in 1956 and served as president in 1972. He received prestigious awards such as the David W. Taylor Gold Medal from the Society of Naval and Marine Engineers, USA, and he was a Commander of Légion d'Honneur.
