Abstract

The blocking assembly includes one or more pre-formed component structures fabricated from a non-corrosive, durable material, each of the component structures including an anchoring flange for attachment to the roof structure, an upper flange defining a mounting base for attachment of various roofing components, materials and/or equipment thereto, and an intermediate portion between the anchoring flange and the upper flange creating depth therebetween to accommodate insulation or lightweight concrete. The intermediate portion is provided with vent holes for venting gases and moisture which accumulate within the roof structure, thereby reducing the likelihood of premature roof failure.

Claims

1. A blocking assembly adapted for the installation of roofing components, materials, insulation materials and equipment on the roof structure of a building said assembly comprising:

an anchoring flange structured and disposed for attachment to the roof structure;

an upper flange defining a mounting base for attachment of the roofing components, materials of equipment thereto, said upper flange extending in parallel, spaced, overlying relation to said anchoring flange to define an area of depth therebetween, and said upper flange and said anchoring flange being adapted for receipt of the insulation materials therebetween;

an intermediate portion including a flat plate extending vertically between said anchoring flange and said upper flange;

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 gases from within said roof structure; and

a fascia portion integral with said anchoring flange and extending downwardly therefrom, said fascia portion including means for installing the roofing components thereto.

2. The blocking assembly as recited in claim 1 wherein said plate of said intermediate portion is perpendicular to said anchoring flange.

3. The blocking assembly as recited in claim 2 wherein said anchoring flange and said upper flange extend from said intermediate portion to define an area of depth therebetween to accommodate roof insulation or lightweight concrete.

4. The blocking assembly as recited in claim 3 wherein said anchoring flange, said upper flange and said intermediate portion are formed as an integral unit.

5. The blocking assembly as recited in claim 4 wherein said integral unit is formed of galvanized steel.

6. The blocking assembly as recited in claim 4 wherein said integral unit is formed of steel.

7. The blocking assembly as recited in claim 4 wherein said integral unit is formed of aluminum.

8. The blocking assembly as recited in claim 4 wherein said integral unit is formed of plastic.

9. A blocking assembly adapted for the installation of roofing components, materials, insulation materials, gutters, and equipment of the roof structure of a building said assembly comprising:

an anchoring flange structured and disposed for attachment to the roof structure, said anchoring flange having a flat top surface;

an upper flange defining a mounting base for attachment of the roofing components, materials or equipment thereto, said upper flange extending in parallel, spaced, overlying relation to said anchoring flange to define an area of depth therebetween;

an intermediate portion including a flat plate extending vertically between said anchoring flange and said upper flange;

vent means formed in said intermediate portion and including a plurality apertures provided at spaced intervals along said intermediate portion for venting moisture and gases from within said roof structure; and

a fascia portion integral with said anchoring flange and extending downwardly therefrom, said fascia portion including means for installing the gutters along an outer perimeter of the roof structure.

10. The blocking assembly as recited in claim 9 wherein said plate of said intermediate portion is perpendicular to said anchoring flange.

11. The blocking assembly as recited in claim 9 wherein said anchoring flange, said upper flange, and said intermediate portion are formed as an integral unit.

12. The blocking assembly as recited in claim 9 wherein said integral unit is formed of steel.

13. The blocking assembly as recited in claim 9 wherein said integral unit is formed of aluminum.
