## Abstract

A roof framing structure (20) is disclosed, and includes a plurality of primary supports (30) (e.g., rafters) that may be disposed in parallel relation and extend along the roof pitch (14). One or more secondary supports (40) extend between each adjacent pair of primary supports (30). Each secondary support (40) is of a triangular cross-sectional configuration, and may extend orthogonally to the various primary supports (30).

## Claims

### Claim 1

A roofing section, comprising:
a roof framing structure comprising a plurality of structural supports, wherein said plurality of structural supports comprises:
a plurality of primary supports, wherein each said primary support has a length dimension that extends in a direction of a roof pitch;
a plurality of secondary supports, wherein each of said plurality of secondary supports comprises a hollow interior, a length dimension that extends in a different direction than said length dimension of said plurality of primary supports, and a closed perimeter which in turn comprises first, second, and third sides, wherein said first side of each said secondary support is flat and defines an uppermost surface of said secondary support, and wherein said first, second, and third sides of each said secondary support collectively define a triangular cross-sectional configuration that is taken perpendicularly to said length dimension of said secondary support; and
a plurality of brackets, wherein each said bracket is attached to a side of one of said plurality of primary supports, wherein each said bracket comprises a V-shaped receptacle, wherein each said secondary support extends between an adjacent pair of said plurality of primary supports, wherein one end portion of each said secondary support is positioned within said V-shaped receptacle of one said bracket attached to one member of the corresponding said adjacent pair, and wherein an opposite end portion of each said secondary support is positioned within said V-shaped receptacle of another said bracket attached to the other member of the corresponding said adjacent pair; and
a panel system disposed in overlying relation to said roof framing structure and comprising a plurality of panels, wherein said first side of each said secondary support is in a relative position to said panel system that is selected from the group consisting of engaging a corresponding flat portion of an underside of said panel system or disposed in closely-spaced relation to said corresponding flat portion of said underside of said panel system, and wherein no portion of said roof framing structure is closer to said underside of said panel system than said first side of said plurality of secondary supports.

### Claim 2 (depends on 1)

The roofing section of claim 1, wherein an elevation of each said primary support continually changes proceeding along its corresponding said length dimension, and wherein an elevation of each said secondary support remains constant proceeding along its corresponding said length dimension.

### Claim 3 (depends on 1)

The roofing section of claim 1, wherein said triangular cross-sectional configuration for each said secondary support comprises an equilateral triangle.

### Claim 4 (depends on 1)

The roofing section of claim 1, wherein said plurality of primary supports are disposed in parallel relation to each other, and wherein said plurality of secondary supports are disposed in parallel relation to each other in a different orientation than said plurality of primary supports.

### Claim 5 (depends on 1)

The roofing section of claim 1, wherein a flat, uppermost surface of each of said plurality of primary supports and a flat, uppermost surface of each of said plurality of secondary supports are coplanar.
