A prefabricated cupola and the like for mounting over a roof ridge comprises a rectangular body and a mounting bracket. The mounting bracket comprises two clam-shell like opposed cylindrical segments that fit under the bottom edges of and fill the gaps beneath the outer walls of the rectangular body when it is centered on the ridge line. The mounting bracket is preferably attached for pivotal motion to the interior bottom edges of the walls straddling the roof ridge. The arms of the cylindrical segments fill the triangular gasp beneath the straddling walls.
