Abstract: Corrugated fine mesh material is configured to be located overlying a gutter. The fine mesh material has an upper edge opposite a lower edge with the upper edge configured to fit beneath shingles on a roof adjacent the gutter. The lower edge is configured to be held to a lip at a forward edge of the gutter. The corrugations add strength to the material and collect water at troughs thereof where the collected water more readily forms droplets that fall down into the gutter. A lower strip is preferably provided to hold the lower edge of the mesh to a lip of the gutter. An upper strip is optionally provided which includes a tab, which can fit beneath shingles to the roof. A barrier such as a bead of caulk can optionally be coupled to an underside of the corrugated mesh to further encourage water droplets to fall.
