A roof system is provided including a roof deck and a first waterproofing membrane disposed upwardly adjacent the roof deck. A channel member is arranged over a portion of the first waterproofing membrane near a perimeter of the roof system. The channel member is secured to the roof deck with a plurality of fasteners. Insulation is arranged upwardly adjacent the first waterproofing membrane A weighted cover board is disposed on top of the insulation. A portion of the insulation and the weighted cover board is arranged within the cavity of the channel member. The first waterproofing membrane surrounds the channel member and extends over a portion of an upper surface of the weighted cover board. A second waterproofing membrane is positioned upwardly adjacent the weighted cover board. The second waterproofing membrane overlaps the portion of the first waterproofing membrane extended over the weighted cover board.
