The invention relates to a method for assembling metal sheets (1, 2), and end portion (1a) of a first metal sheet (1) overlapping an end portion (2a) of a second metal sheet (2), with application of a line of sealing adhesive (3) over a width of the end portion of one of the metal sheets (1, 2), overlapping the end portions (1a, 2a) and squeezing the line of adhesive (3) between the end portions (1a, 2a), locally securing the end portions (1a, 2a) to one another, applying a first mastic seal line (4) to a free end of the end portion (1a) of the first metal sheet (1) and to a facing zone of the second metal sheet (2), turning over the metal sheets (1, 2) and applying a second mastic seal line (5) to a free end of the end portion (2a) of the second metal sheet (2) and to a facing zone of the first metal sheet (1).
