10. The device of claim 1 , wherein a bottom of a trough of the at least one trough is below in elevation from a top of the gutter lip rail.
11. The of claim 1 , wherein a trough of the at least one trough has a gutter lip side wall inclined in a direction towards the gutter lip rail and has a roof side wall joined to a bottom of the gutter lip side wall and inclined at an angle greater than 90 degrees from the gutter lip side wall, wherein the roof side wall is longer than the gutter lip side wall.
12. The device of claim 11 , wherein the gutter lip side wall is proximal to the gutter lip rail.
13. The device of claim 1 , wherein a cross-section of the at least one trough is U-shaped.
14. The device of claim 1 , wherein a cross-section of the at least one trough is partially U-shaped.
15. A gutter debris preclusion device for securing to a top portion of a gutter that is attached to a building, comprising:
a mesh having apertures, corrugations, a roof side, a gutter lip side, a gutter lip portion, and a water dam with corrugations disposed proximal to and parallel to the gutter lip portion, wherein the mesh is configured to substantially cover a gutter when the device is in use; and
a gutter lip rail attached to the gutter lip portion.
16. The device of claim 15 , wherein the water dam is formed from a first and second wall, joined at a bottom, wherein the bottom is below the gutter lip rail when the device is in use.
17. The device of claim 15 , further comprising a plurality of water dams.
18. The device of claim 16 , wherein at least one of the first and second wall is curved.
19. The device of claim 16 , wherein the joined walls form a contiguous curved shape.
20. The device of claim 16 , wherein a top portion of the first wall is connected to a gutter lip.
21. The device of claim 16 , further comprising a roof side rail attached to the roof side.
22. A gutter debris preclusion device for securing to a top portion of a gutter that is attached to a building, comprising:
a mesh having apertures, corrugations, a roof side, a gutter lip side, and a gutter lip portion terminating the gutter lip side, wherein the mesh is sized to substantially cover a gutter;
wherein a first plane of the gutter lip side is different from a second plane of the roof side, forming at least one offset between the first and second planes, the at least one offset being bridged by one or more third planes of the mesh; and
wherein a roof side end of the one or more third planes of the mesh being lower than a gutter lip side end of the one or more third planes of the mesh.
23. The device of claim 22 , wherein a width spanned by the first plane is less than a width spanned by the second plane.
24. The device of claim 22 , wherein a depth of the at least one offset operates as a water reservoir.
25. The device of claim 22 , wherein the corrugations are disposed in the second plane.
26. The device of claim 22 , wherein the corrugations are disposed in the one or more third planes.
27. The device of claim 22 , wherein a cross-section of the at least one offset is curved in shape.
28. A gutter debris preclusion device for securing to a top portion of a gutter attached to a building, comprising:
a water permeable mesh having corrugations, a roof side, a gutter lip portion, and a trough disposed parallel to and proximal to the gutter lip portion, wherein the mesh is sized to substantially cover a prospective gutter attached to a prospective building, wherein the trough has a longer first wall extending towards the roof side and a shorter second wall extending towards the gutter lip portion, wherein a shape of the longer first wall and shortrer second wall form a 2-sided reservoir, and wherein a bottom point of the reservoir is lower than the gutter lip portion; and
a gutter lip attachment member coupled to the gutter lip portion.
29. The device of claim 28 , wherein an angle between the longer first wall and shorter second wall is greater than 90 degrees.
