1. A system comprising:
a rain gutter defining a vertically upward facing open channel between a first longitudinal lip affixed adjacent to a roof fascia and a second longitudinal lip disposed at least substantially parallel to the first longitudinal lip; and
a first drainage grate comprising:
a first support member having a first support member length and comprising a beam leg;
a second support member spaced at least substantially equidistant from the first support member along at least a majority of the first support member length;
a first support beam extending along a first support beam length and spaced at least substantially equidistant from the first support member along at least a majority of the first support member length, the first support beam being located between and spaced from the first support member and the second support member;
a second support beam extending along a second support beam length and spaced at least substantially equidistant from the second support member along at least a majority of the second support member length, the second support beam being located between and spaced from the first support beam and the second support member;
a first plurality of drainage ribs extending from the first support member to the first support beam, a majority of the first plurality of drainage ribs having an upper surface extending from a first end coupled to the first support member to a second end coupled to the first support beam;
a second plurality of drainage ribs extending from the first support beam to the second support beam, a majority of the second plurality of drainage ribs having an upper surface extending from a first end coupled to the first support beam to a second end coupled to the second support beam; and
a third plurality of drainage ribs extending from the second support beam to the second support member, a majority of the third plurality of drainage ribs having an upper surface extending from a first end coupled to the second support beam to a second end coupled to the second support member,
wherein the second end of the upper surface of the majority of the first plurality of drainage ribs terminates in a knee that is positioned at a greater distance from the first support beam than the first end of the upper surface of the majority of the second plurality of drainage ribs, and
wherein the second end of the upper surface of the majority of the second plurality of drainage ribs terminates in a knee that is positioned at a greater distance from the second support beam than the first end of the upper surface of the majority of the third plurality of drainage ribs.
