This diagram shows you the components of a TPO roofing system. TPO is a single- ply roofing membrane that is mechanically attached to wood or metal. TPO roofing membranes are among the fastest growing commercial roofing products and have gained broad industry acceptance for their many performance and installation advantages. Though TPO is mechanically attached to wood or metal, a concrete base has to be done differently. It actually has to be a fully adhered system rather than a TPO system.
