The present invention relates to a roof window structure and a roof window installed therewith, comprising at least one horizontal part, the top edge of the front surface of the horizontal part extends forward and then gradually downward to the front bottom edge of the horizontal part. Between the top edge and bottom edge of the horizontal part there forms at least one operative surface that cooperates with a flashing part connected to the window. The operative surface can be a curved concave surface; it well protects the flashing part. The operative surface also has at least one front top edge extending outward then exceeding the covering connected with the sash, thus well protects the covering. The exterior surface of the frame is configured a sloped surface along the basic edge facing outwards and along the glass of the window. This configuration saves the material for the frame and lowers the production cost.
