A garage door apparatus includes a frame for mounting above an opening, the frame comprising a pair of spaced transverse frame members, a shaft rotatably coupled to the transverse frame members and extending along a longitudinal axis of rotation between the transverse frame members, a pair of spaced winding frames rigidly coupled to the shaft between the spaced transverse frame members, each of the winding frames having a plurality of side edges, a driver couplable to the shaft for rotating the shaft with respect to the transverse frame members, and a plurality of door panels hingedly coupled together and linked to the winding frames, each of the door panels being of equal width and having a longitudinal panel length, the plurality of door panels including at least one inner door panel and at least one outer door panel, wherein the winding frames are spaced apart a predetermined distance that is less than the longitudinal panel length of the plurality of door panels, such that when the winding frames are rotated by the driver about the axis of rotation, the side edges of the winding frames progressively engage each of the door panels, thereby moving the door panels between an extended position wherein the door panels obstruct the opening, and a retracted position wherein each door panel is wound onto one of the side edges of the winding frames, the opening is at least partially unobstructed, and the at least one outer door panel overlaps with the at least one inner door panel.
