An integral truss system (20) for a roof (31) includes a pair of opposing end trusses (22) that can span between opposing (e.g. outer) walls of a building. At least one side truss (24) extends between the end trusses (22). The side truss is adapted for supporting a floor load and transferring that load to the end trusses (22). In addition, a roof portion (34) can be part of the roof (31) and can be moved between open and closed positions.
