Abstract
A roof structure and its components comprises a series of metal panels having flanges that interlock when the panels are laid side by side and which are subsequently tightly seamed together to convert the individual panels into an integrated roof forming membrane. The roof structure may be insulated through the use of a blanket vapor barrier and insulation under the panels preferably along with thermal blocks located over the purlins. The roof structure includes unique flexible panel mounting clips that attach the panels to the purlins in such a way as to permit the panels to expand or contract in response to temperature and pressure changes, thereby minimizing roof stressing.
