Abstract:
1. A tile assembly for installation on a roof comprising: a plurality of tiles having a main surface with upper and lower vertical apices and left and right lateral apices; wherein the main surface is flat throughout; at least two upper flanges extending peripherally directly from the main surface between the upper apex and lateral apices; wherein the at least two upper flanges extend directly from the main surface at an obtuse angle in a first direction; at least two lower flanges extending peripherally directly from the main surface between the lower apex and lateral apices; wherein the at least two lower flanges extend directly from the main surface at an obtuse angle in a second direction; wherein the first direction is directly opposite to the second direction such that the at least two upper flanges are parallel within 20 degrees to the at least two lower flanges with respect to the directions of extension from the main surface; and at least two inflection edges positioned at the lateral apices of each tile, wherein each inflection edge is defined by transition edges of the upper and lower flanges and an adjacent portion of the main surface; wherein the plurality of tiles includes a left and right center tile positioned so as to abut at their adjacent inflection edges; wherein the plurality of tiles includes an upper tile positioned with its two lower flanges overlapping the two adjacent upper flanges of the left and right center tiles; and wherein the plurality of tiles includes a lower tile positioned with its two upper flanges underlying the two adjacent lower flanges of the two center tiles.
