摘要

A roof system positionable over an existing roof wherein the roof system is formed of at least one roof section. The roof section includes (a) a plurality of adjustable trusses disposed along a preselected section of the existing roof, each of the trusses having a lower cord, a spatially disposed upper cord and an adjustable web assembly interconnecting the lower cord and the upper cord, the lower cord of each truss disposed substantially adjacent the existing roof such that the trusses extend upwardly from the existing roof in a substantially parallel relationship with the adjacently disposed trusses, the web assembly of each of the trusses being adjustable such that the upper cord of each of the trusses is substantially horizontally disposed a selected predetermined height above the existing roof and independent of the slope of the existing roof and the position of the lower cord; (b) truss fastener members for connecting the lower cord of each of the trusses to the existing roof; (c) at least one roof panel member supported by the upper cords of the trusses, the roof panel member being disposed to substantially traverse the upper cords of the trusses; and (d) fastener members for connecting the roof panel member to the upper cords of the trusses to form the roof system having a predetermined roof plane substantially independent of the plane of the existing roof. The roof system is further provided with gutter assemblies. A method for installing the roof system over an existing roof is also provided.
