1. A roof system, comprising:
a frame;
a plurality of roof panels, wherein each roof panel is connected to the frame and is rotatable with respect to the frame; and
a holding mechanism for holding a first roof panel among the plurality of roof panels in a closed position,
wherein each roof panel has a center of mass and a center of rotation, wherein the center of mass is offset from the center of rotation to allow each roof panel to rotate upon release of the holding mechanism,
wherein each roof panel among the plurality of roof panels overlaps or is overlapped by at least one adjacent roof panel among the plurality of roof panels,
wherein release of the holding of the first roof panel by the holding mechanism causes each of the roof panels to rotate toward an open position in a sequential manner, and
wherein adjacent ones of the plurality of roof panels rotate in opposite directions toward the open position.
