Building roof structure

DETAILED DESCRIPTION The roof system embodying the present invention does not require penetration into the interior of the building to affix a roof system to a building support system.
The roof system includes a plurality of elongate panels which are coupled together with side adjacent panels via standing seams.
The panels are oriented on the roof to be in overlapping relationship with end adjacent panels.
Thus, as viewed from the building ridge toward the building side, some of the panels have that end thereof located farther from the ridge overlapping the end of the next end adjacent panel which end is located nearer to the ridge.
Furthermore, the ends of the panels located nearer the ridge have a closed end structure which prevents water from splashing out of the panel.
The panels are mounted on roof purlins, or the like, via clips and brackets.
Screws penetrate the panels to attach the panels to the brackets.
However, such penetration is located in the overlapping area so that a panel backstop and a bracket, as well as further insulation, or the like, is interposed between that penetration location and the building interior.
The brackets are coupled to the purlins and are flexible to permit thermally induced panel movement to be accommodated through flexure of the brackets.
Thus, there are no penetrations through the roof into the interior of the building.
The attachments of the roof to the elements attached to the roof purlins, or the like, occur outside of the building.
Leak paths through the roof elements will be located outside the building.
OBJECTS OF THE INVENTION It is the main object of the present invention to provide a roof structure for a building wherein attachment of such roof to building support elements does not require penetration into the area enclosed by the roof.
Another object of the present invention is to provide a roof structure which accommodates thermally induced roof movement.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like reference numerals refer to like parts throughout
