Abstract

A roofing insert, comprising a molded insert made with insulating material having at least one planar surface opposed by either a non-planar surface or more than one non-parallel surface.

What is claimed is: 
     
         1 . A roofing insert, comprising:
 a molded insert made with insulating material having at least one planar surface opposed by either a non-planar surface or more than one non-parallel surface.   
     
     
         2 . The insert according to  claim 1 , wherein said insulating material is selected from the group consisting of polyisocyanurate, polyurethane, polystyrene, and lightweight insulating concrete (LWIC). 
     
     
         3 . The insert according to  claim 1 , further comprising:
 a plurality of sidewalls extending from said at least one planar surface, each side wall having a top edge, wherein said non-planar surface slopes downwardly from said top edges.   
     
     
         4 . The insert according to  claim 3 , further comprising:
 a platform which is connected to said non-planar surface at about a central position of the insert.   
     
     
         5 . The insert according to  claim 3 , wherein said molded insert is segmented into at least two segments, wherein a mating segment joint extends along a facing surface of each said segment. 
     
     
         6 . A roofing insert, comprising:
 a molded insert made with insulating material having a planar bottom surface, an abutment surface extending from said planar bottom surface, and wherein the planar bottom surface and the abutment surface are connected by two sloping surfaces.   
     
     
         7 . The insert according to  claim 6  wherein each sloping surface has a top edge, and wherein said top edges meet at an apex. 
     
     
         8 . The insert according to  claim 6 , wherein said insulating material is selected from the group consisting of polyisocyanurate, polyurethane, polystyrene, and lightweight insulating concrete (LWIC). 
     
     
         9 . A roofing system comprising:
 (i) a deck board layer;   (ii) an insulation board layer disposed on said deck board, said insulation board layer having an insulation board layer opening;   (iii) a molded insert received in said insulation board layer opening; and   (iv) a membrane layer disposed over said insulation board layer and said molded sump.   
     
     
         10 . The roofing system according to  claim 9 , wherein said molded insert is made with insulating material having at least one planar surface opposed by either a non-planar surface or more than one non-parallel surface. 
     
     
         11 . The roofing system according to  claim 10 , wherein said insulating material of the molded insert is selected from the group consisting of polyisocyanurate, polyurethane, polystyrene, and lightweight insulating concrete (LWIC). 
     
     
         12 . The roofing system according to  claim 10 , the molded insert further comprising:
 a plurality of sidewalls extending from said at least one planar surface, each side wall having a top edge, wherein said non-planar surface slopes downwardly from said top edges.   
     
     
         13 . The roofing system according to  claim 12 , the molded insert further comprising:
 a platform which is connected to said non-planar surface at about a central position of the insert.   
     
     
         14 . The roofing system according to  claim 12 , wherein said molded insert is segmented into at least two segments, wherein a mating segment joint extends along a facing surface of each said segment. 
     
     
         15 . A roofing system containing a vertical abutment means comprising:
 (i) a sloped roof deck comprising:
 a) a deck board layer; 
 b) an insulation board layer disposed on said deck board; and 
 c) a membrane layer disposed over said insulation board layer; 
   (ii) a vertical abutment means, wherein the intersection of the sloped roof deck and the vertical abutment means creates a roof-abutment intersection; and   (iii) a molded insert received within the roof-abutment intersection.   
     
     
         16 . The roofing system of  claim 15 , wherein said molded insert is made with insulating material and said insulating material is selected from the group consisting of polyisocyanurate, polyurethane, polystyrene, and lightweight insulating concrete (LWIC). 
     
     
         17 . The roofing system of  claim 15 , wherein the molded insert comprises a planar bottom surface, an abutment surface extending from said planar bottom surface, and wherein the planar bottom surface and the abutment surface are connected by two sloping surfaces. 
     
     
         18 . The roofing system of  claim 17 , wherein the planar bottom surface of the mold insert is placed adjacent the sloped roof deck and the abutment surface is placed adjacent the vertical abutment means within the roof-abutment intersection. 
     
     
         19 . The roofing system of  claim 17 , wherein each sloping surface has a top edge, and wherein said top edges meet at an apex. 
     
     
         20 . The roofing system of  claim 15 , wherein the vertical abutment means is a chimney.
