A prefabricated building structure generally consisting of at least two modular units having complementary roof systems secured together to provide an integral building structure, each of the complementary roof systems including a longitudinally disposed stationary roof section and a longitudinally disposed movable roof section hingedly connected along a longitudinal axis to the stationary roof section, the stationary roof section having upwardly projecting seating means, the movable roof section having rigidly connected, depending support means and an extension leg hingedly connected to the depending support means whereby the extension leg may be moved away from the seating means and the depending support means may be seated on the seating means to support the movable roof section in a downwardly disposed, inoperative position, and the extension leg may be moved between the depending support means and the seating means and seated on the seating means to support the movable roof section in an upwardly disposed, operative position, means rigidly interconnecting the opposed free ends of the movable roof sections of the complementary roof systems when the movable roof sections are upwardly disposed in their operative position, and means for covering the roof systems when the movable roof section are disposed in their operative positions.
