Edge closure with cant for roof systems

Abstract

An integral, pre-formed edge closure fabricated from a non-corrosive, durable material includes an anchoring flange for attachment to a roof structure, an upper flange, an intermediate panel spanning between the anchoring flange and the upper flange, a cant panel positioned at an acute angle relative to the upper flange to define a cant strip along a length of the edge closure, and a mounting strip above the cant panel for securing the edge closure to a concrete parapet or other adjoining vertical wall on a roof structure. The anchoring flange and upper flange are spaced apart for receiving a thickness of insulation of lightweight concrete therebetween. The intermediate panel is provided with vent holes for venting gasses and moisture which accumulate within the roof structure, thereby reducing the likelihood of premature roof failure. In one embodiment, the mounting strip extends vertically to a top plate and downwardly depending lip.

What is claimed is:  
     
         1 . An edge closure for installation to a roof structure of a building, wherein the roof structure includes insulation materials, said edge closure comprising: 
 an anchoring flange structured and disposed for attachment to the roof structure;    an upper flange positioned and disposed in parallel, spaced relation above said anchoring flange to define an area of depth therebetween for receipt of the insulation materials between said upper flange and said anchoring flange;    an intermediate portion including a flat plate extending vertically between said anchoring flange and said upper flange;    a cant panel angled upwardly from said upper flange to define a cant strip;    a mounting strip, extending upwardly from said cant panel, said mounting strip being structured and disposed for attachment to the roof structure; and    a top plate extending perpendicularly from said mounting strip and opposite to said cant strip and said upper flange.    
     
     
         2 . The edge closure as recited in  claim 1  further comprising: 
 vent means formed in said intermediate portion and including a plurality of apertures provided at spaced intervals along said intermediate portion for venting moisture and gasses from within said roof structure.  
 
     
     
         3 . The edge closure as recited in  claim 1  further comprising: 
 a downwardly depending lip extending from said top plate.  
 
     
     
         4 . An edge closure for installation to a roof structure of a building, wherein the roof structure includes a slab, a parapet or vertical wall extending upwardly and generally perpendicular to the slab, and insulation materials applied in overlying relation to the slab, said edge closure comprising: 
 an integral one-piece unit comprising: 
 an anchoring flange structured and disposed for attachment to the slab of the roof structure;  
 an upper flange positioned and disposed in parallel, spaced relation above said anchoring flange to define an area of depth therebetween for receipt of the insulation materials between said upper flange and said anchoring flange;  
 an intermediate portion including a flat plate extending vertically between said anchoring flange and said upper flange;  
 a cant panel angled upwardly from said upper flange at an acute angle to define a cant strip;  
 a mounting strip extending upwardly from said cant panel, said mounting strip being structured and disposed for mating engagement and attachment to the parapet or vertical wall of the roof structure; and  
 a top plate extending perpendicularly from said mounting strip and opposite to said cant strip and said upper flange.  
   
     
     
         5 . The edge closure as recited in  claim 4  further comprising: 
 vent means formed in said intermediate portion and including a plurality of apertures formed at spaced intervals along said intermediate portion for venting moisture and gases from within said roof structure.  
 
     
     
         6 . The edge closure as recited in  claim 4  further comprising: 
 a downwardly depending lip extending from said top plate.
