The present invention relates to a horizontally-roofed roof in which a laterally elongated roofing material is laid in a direction perpendicular to the inclination direction of the roof, and particularly to a horizontally-thatched roof in which a hard base member is provided in an overlapping manner on the lower surface of the roofing material.

<Prior Art> As is well known, as a type of roof for a building, a locking part that bends downward is provided on the front edge of a horizontally long board, and an engaging part that bends upward is provided on the rear edge. There are horizontal roofs in which the plates are successively blown in a direction perpendicular to the direction of the roof's inclination, and a base material is attached to the bottom of the plates for the purpose of heat insulation and soundproofing. A conventional horizontal roof is raised by fitting the engaging part of the roofing material located on the eaves side with the locking part of the roofing material located on the ridge side.
