Abstract
Abstract An auxiliary insulated roof system for mobile homes, metal buildings and the like includes a generally continuous panel structure of insulation material, a plurality of insulated support blocks for supporting the panel structure in clearance relation above the building roof surface and a plurality of fastening brackets for securing the panel structure to the building sidewalls. The insulated support blocks may include a base plate having a stud extended from one side for penetrating the panel structure and a block of insulation material secured to the opposite side thereof. The insulation blocks may be connected to elongated straps at spaced-apart positions therealong with opposite ends of the straps secured to the building sidewalls for partially securing the panel structure in place. A trim strip covers the fastening brackets and opening between the panel structure and roof surface. The panel structure includes a plurality of panels of insulation material, the panels having rabbeted ends and being arranged to end-to-end shiplapped relation. A cover sheet is secured to the exterior surface of each panel and includes an overlap portion at one end which is adapted to overlie and be secured to the adjacent panel to form a continuous panel structure.
