ABSTRACT:
A retrofit roof riser subframing support assembly for attaching a new roof over an existing roof wherein the new roof has a slope independent of the slope of the existing roof. The assembly can include a series of spaced apart rows of roof support members having one end attachable to the new roof structure and another end mountable on the existing roof. Each row of roof support members can have a different height such that the difference in height between the tallest row and the shortest row defines the slope of the new roof. Each roof support member can include at least one fixed length post member having one end retained in a socket portion of a mounting member which is mountable on the existing roof. The other end of the post member can have a purlin clip rotatably connected thereto. The purlin clip can be rotated to the desired angle, locked in place, and attached to the new roof structure. The assembly can also include a sleeve member for connecting at least two fixed length post members together to form a roof support member having a desired height. All of the aforementioned components can be provided in kit form.
