A roof paver system includes a plurality of roof paver elements having alternating dovetail-shaped and tapered grooves and an upper surface having raised portions to generate vortices for preventing wind from lifting the elements and to provide a safety tread. Connector members are provided in some of the dovetail grooves to interconnect the roof paver elements to further prevent their displacement. The tapered grooves break the vacuum between the roof paver elements and the molds in which they are formed. Some of the dovetail grooves are composite grooves defined by the cooperation of adjacent roof paver elements. Clips are provided to mate with outwardly projecting toes on the roof paver elements in perimeter courses to align and anchor them, and elongate battens, which are dovetail-shaped in cross section, are received in the dovetail grooves and include openings for receiving thin elements transverse to the battens to engage the concrete elements at the ends of the grooves. In one embodiment, the connector members have a truncated triangular cross section to provide a substantial area of contact with the walls of the dovetail grooves and ridges to bind against the walls. Flange stops project from the connector members to engage the roof paver elements at the ends of the dovetail grooves, and one end of the connector member has a bevel to mate with a roof paver element oriented with its grooves perpendicular to the connector member. |
