A gutter protection assembly includes a frame, stanchions, and a mesh. The frame includes a rear brace and a supporting flange. The supporting flange is detachably attached to a front lip of a gutter using fasteners. The frame is defined by a series of alternating parallel ridges and a series of parallel channels such that each of the parallel channels define equally spaced openings. Each of the two self-supported stanchions include a base portion, an elongate stem portion inclined relative to the base portion, and two jaw portions extending from an end of the elongate stem portion that include a support clip for receiving adjacent portions of parallel ridges of the frame to define a space between a rear lip of the gutter and the rear brace of the frame. A mesh covers the frame to filter debris through the gutter.
