ABSTRACT:
A roof structure is fabricated by forming a lattice of support straps between the inclined rafters and the purlins, supporting one or more reels of insulation material on adjacent pairs of purlins with the width of the material spanning the space between the purlins, moving the reels along the lengths of the purlins and paying out the insulation material from the reels down into the spaces between the purlins and onto the lattice of support straps. Additional insulation material is applied to the upper surfaces of the purlins. The workmen follow the reels of insulation material and connect the hard roofing material over the insulation material to the purlins to complete the roof structure.
