The prefabricated roof structure is a self-supporting surface (1) with a bend-resistant bond (3) in one piece with a jamb (2), to be placed on a building top or an outer wall (5). The bend-resistant bond (3) is formed by wood boards, glued to the flat surface (1) and the jamb (3), or a combination of nails and glue or by dowels with steel plates.
