A roof screen system comprises a number of triangular frames assembled from aluminum beams held together with pivotable clamps. Such clamps also bolt down onto roof footers with flashing boots that prevent roof leaks. A number of clips are attached to the upright triangular frames. Horizontal rails are then attached with the clips to the triangular frames, and screen panels are hung and attached to the rails. The pivotable clamps allow a slip-connection anywhere along the aluminum beams that can be locked down with ordinary wrenches. As such, the screen panels can be tilted back or forward to accommodate painted signs, electric signs, advertising, and even solar photovoltaic panels.
