A paint roller edge guard apparatus facilitating the painting of a wall surface adjacent a non-painted surface from the application of paint to the non-painted surface from the roller sock. The apparatus comprises a handle and an edge guard having four edges and front and back faces. The edge guard is pivotally and rotatable supported on the handle. The roller is rotatably supported on the handle such that the roller may be rotated between a painting position, wherein the roller sock longitudinal axis is perpendicular to and adjacent the edge guard front face, and a filling position wherein the roller sock longitudinal axis is parallel to the edge guard front face. The roller sock may be placed in contact with the painted wall by application of pressure to the handle deflecting the edge guard rearward allowing the roller sock to contact the painted wall surface. In an alternative embodiment, the roller and edge guard may be mounted on separate handle portions such that the edge guard and roller may be separated by separating the handle portions. A toothed roller may also be associated with the roller to facilitate its rotation on slick surfaces.
