Abstract
An improved method and apparatus is disclosed for a roofing system which uses an improved standing seam joint such that the roofing system can be used for flat roof applications. A standing seam is conventionally formed and then compressed in a press fit manner by compression apparatus. Provisions are made to apply a gasket material to the compressed sections of the standing seam prior to compression which material is deformed when the seam is compressed to provide a sealed joint which is significantly stronger than the conventional standing seam.
