A ballast block deck system includes a plurality of ballast blocks (12) laterally positioned to form an elevated deck (14) on an existing roof structure. Each block (12) has a predetermined thickness and multiple corner portions (22). A pedestal assembly (30) is located directly beneath the corner portions (22) of adjacent ballast blocks (12) to space and support the blocks (12) a spaced distance above the existing roof surface. The pedestal assembly (30) includes a support plate (34) having a support surface (40) for supporting the corner portions (22) thereon, a cornercap (42) which overlies the corner portions (22), and a fastener (44) which removably attaches the cornercap (42) to the support plate (34). When installed, the corner portions (22) of adjacent ballast blocks (12) are captured between the support plate (34) and cornercap (42) of the pedestal (30). Preferably, the corner portions (22) of the ballast blocks (12) include a recessed area (18) so that the cornercap (42) lies flush with the top surface (16) of the ballast blocks (12), and preferably, the corner portions (22) have a groove (20) for cooperatively engaging a flange (56) depending from the cornercap (42) so that lateral movement of the blocks (12) relative to the pedestal (30) and to other blocks (12) is prevented. |
