## Abstract

A metal roof panel includes a rib with a unique shape. The rib is bilateral with upwardly angled sides that each transition into an indentation, with both indentations transitioning into a central flat apex. Between each rib is a channel, preferably including at least one raised surface. The lower surface of the channel between the raised surfaces, and the top of the raised surfaces, are substantially planar and parallel to the flat surface of the apex of the panel. A unique method of manufacturing the roof panel employs a roll machine configured to shape a piece of sheet metal into the roof panel by modifying the shape in many small increments, which allows the final product to have a fairly intricate bend pattern.

## Claims

### Claim 1

A roof panel having a profile including:
A. a plurality of bilateral ribs having upwardly angled sides that each transition into an indentation, with both indentations transitioning into a central flat apex extending from one of said indentations to the other of said indentations and having a width of approximately ⅝″; and
B. a plurality of channels each positioned between two of said ribs, each channel including at least one raised surface and at least one lower surface, said raised portion haying a height of approximately ⅛″, and wherein said at least one raised surface and at least one lower surface are each substantially planar and parallel to said central flat apex .

### Claim 2 (depends on 1)

The roof panel of claim 1 wherein the angle formed between one of said upwardly angled sides and said central flat apex is approximately 126°.

### Claim 3 (depends on 1)

The roof panel of claim 1 wherein the angle formed between one of said upwardly angled sides and said raised surface is approximately 54°.

### Claim 4 (depends on 1)

The roof panel of claim 1 wherein each channel includes exactly two raised surfaces and exactly three lower surfaces.

### Claim 5 (depends on 1)

The roof panel of claim 1 wherein said raised surfaces are parallel to said lower surfaces.

### Claim 6 (depends on 5)

The roof panel of claim 5 wherein said central flat apex is parallel to said raised surfaces.

### Claim 7

A method of installing a metal roof including the steps of:
A. Positioning a roof panel on a roof, said roof panel having a profile including a plurality of bilateral ribs having upwardly angled sides that each transition into an indentation, with both indentations transitioning into a central flat apex; and plurality of channels each positioned between two of said ribs, each channel including at least one raised surface and at least one lower surface; and
B. Attaching said roof panel to said roof with a plurality of fasteners positioned primarily along said central flat apex.

### Claim 8 (depends on 7)

The method of claim 7 wherein said step of attaching said roof panel to said roof includes the step of tightening said fasteners.

### Claim 9 (depends on 8)

The method of claim 8 wherein said step of tightening said fasteners includes the step of ceasing tightening prior to deformation of said roof panel.

### Claim 10 (depends on 7)

The method of claim 7 wherein said step of attaching said roof panel to said roof includes the step of fastening at said channel, wherein said quantity of fasteners along said central flat apex is greater than the quantity of fasteners at said channel per metal roof.

### Claim 11

A method of manufacturing metal roof panel including the steps of:
A. Inserting a panel of sheet metal into a roll machine;
B. Passing said sheet metal through a first roller set to form sheet metal post-first roller;
C. Passing said sheet metal post-first roller through a second roller set to form sheet metal post-second roller;
D. Passing said sheet metal post-second roller through a third roller set to form sheet metal post-third roller;
E. Passing said sheet metal post-third roller through subsequent rollers to form a profile including a plurality of bilateral ribs having upwardly angled sides that each transition into an indentation, with both indentations transitioning into a central flat apex; and plurality of channels each positioned between two of said ribs, each channel including at least one raised surface and at least one lower surface.

### Claim 12 (depends on 11)

The method of claim 11 wherein said step of passing said sheet metal post-third roller through subsequent rollers includes forming a profile having an angle between said upwardly angled side and said central flat apex of approximately 126°.

### Claim 13 (depends on 11)

The method of claim 11 wherein said step of passing said sheet metal post-third roller through subsequent rollers includes forming a profile having an angle between said upwardly angled side and said raised surface of approximately 54°.

### Claim 14 (depends on 11)

The method of claim 11 wherein said step of passing said sheet metal post-third roller through subsequent rollers includes forming a profile having exactly two raised surfaces and exactly three lower surfaces.

### Claim 15 (depends on 11)

The method of claim 11 wherein said step of passing said sheet metal post-third roller through subsequent rollers includes forming a profile having raised surfaces parallel to said lower surfaces.

### Claim 16 (depends on 15)

The method of claim 15 wherein said step of passing said sheet metal post-third roller through subsequent rollers includes forming a profile having said central flat apex parallel to said raised surfaces.

### Claim 17 (depends on 11)

The method of claim 11 wherein said step of inserting a panel of sheet metal into a roll machine includes the step of inserting a panel of 29 gauge GALVALUME sheet metal.
