Nach dem Studium in Heidelberg arbeitete er unter Robert Wilhelm Bunsen, mit dem ihn eine lebenslange Freundschaft verband. Er übernahm 1857 den Lehrstuhl für Chemie am Owens-College in Manchester. Seine wichtigsten Arbeitsgebiete waren Fotometrie (Bunsen-Roscoe-Gesetz) und Spektralanalyse sowie die Chemie der Übergangselemente Wolfram und Vanadium. So stellte er 1867 metallisches Vanadium dar. Ein von James Blake 1876 erstbeschriebenes Mineral erhielt Roscoe zu Ehren den Namen Roscoelith.

4to. 1 p. Double sheet. Lined paper. On corner missing. Roscoe accepting an invitation: Archibaldus Geikie | salute Je igitur, vir praeclarissimus, accepto coro delecto rogam honorabilissimum date in nomine tus et consilio et sodale Societatis nostrae, ut in die XVI mensis Julii et duobus insequentibus Diebus celebrare Vobiscu natalem nostrum Vale". He is particularly noted for early work on vanadium, photochemical studies, and his assistance in creating Oxo (food), in its earlier liquid form.Roscoe's scientific work includes a memorable series of researches carried out with Bunsen between 1855 and 1862, in which they laid the foundations of comparative photochemistry. In 1864 they carried out what is reputed to be the first flashlight photography, using magnesium as a light source.[8] In 1867, Roscoe began an elaborate investigation of vanadium and its compounds, and devised a process for preparing it pure in the metallic state, at the same time showing that the substance which had previously passed for the pure metal was contaminated with oxygen. In so doing he corrected Berzelius's value for the atomic mass. Roscoe was awarded the 1868 Bakerian Lecture for this work. He also carried out researches on niobium, tungsten, uranium, perchloric acid, and the solubility of ammonia.
