Abstract

In a roofing structure, two roof panels with different slopes and lengths are positioned back-to-back, the vertical back walls of the panels having a uniform height. The seam between the two differently-sloped panels are connected by a ridge cap set at a uniform height. The ridge cap covers the seam, extending on both sides to a distance from the back walls of the roof panels sufficient to create a capillary break therefrom (preventing moisture migration) and then downwards and slightly towards the back walls of the roof panels, thereby using gravity to direct the water into the downward sloping roof panels.

First claim

What is claimed is:

1. A roofing structure comprising:
a first roof panel having (a) a first bottom sheet, (b) a first side sheet and a second side sheet, the first side sheet and the second side sheet being positioned at opposite sides of the first bottom sheet, and (c) a first back wall connecting the first side sheet, the second side sheet, and the first bottom sheet, wherein the first bottom sheet is positioned so as to be angled at a first slope, a vertically-highest side of the first bottom sheet being at an intersection of the first bottom sheet with the first back wall, and wherein a vertical distance from a vertically-lowest portion of the first bottom sheet to a vertically-highest portion of the first back wall is of a first height;
a second roof panel having (a) a second bottom sheet, (b) a third side sheet and a fourth side sheet, the third side sheet and the fourth side sheet being positioned at opposite sides of the second bottom sheet, and (c) a second back wall connecting the third side sheet, the fourth side sheet, and the second bottom sheet, wherein the second bottom sheet is positioned so as to be angled at a second slope that is different than the first slope, a vertically-highest side of the second bottom sheet being at an intersection of the second bottom sheet with the second back wall, and wherein a vertical distance from a vertically-lowest portion of the second bottom sheet to a vertically-highest portion of the second back wall is of the first height; and
a ridge cap;
wherein the first roof panel and the second roof panel are positioned adjacent to each other, the first roof panel and the second roof panel being separated by a gap, and
wherein the ridge cap is positioned so as to seal the gap between the roof panels.

2. The roofing structure of claim 1 , wherein the first bottom sheet has a first length, and the second bottom sheet has a second length that is different than the first length.

3. The roofing structure of claim 1 , wherein an external side of the back wall of the first roof panel is positioned so as to face an external side of the back wall of the second roof panel,
wherein the ridge cap is positioned so as to cover the gap between the roof panels, the gap being a gap between the external side of the back wall of the first roof panel and the external side of the back wall of the second roof panel,
wherein the ridge cap comprises a first pane extending from a first position above the gap between the roof panels to a second position that is above the first bottom sheet of the first roof panel, at a vertical height that is lower than the first height, and at a horizontal distance from the back wall of the first roof panel that is greater than a length sufficient to create a capillary break for water at a predetermined temperature and pressure, and
wherein the ridge cap further comprises a second pane extending from the second position to a third position that is above the first bottom sheet of the first roof panel, at a vertical height that is lower than the vertical height of the second position, and is located horizontally closer to the back wall of the first roof panel than the second position.

4. The roofing structure of claim 1 , further comprising:
a z-shaped clip attached to the back wall of the first roof panel, wherein the z-shaped clip has an overhang that extends away from the back wall of the first roof panel, and
wherein the ridge cap is positioned such that the first pane of the ridge cap extends to a position farther from the back wall of the first roof panel than a termination point of the overhang of the z-shaped clip, and the second pane of the ridge cap extends to a position closer to the back wall of the first roof panel than the termination point of the overhang of the z-shaped clip.

5. The roofing structure of claim 1 , further comprising:
a gutter attached to the vertically-lowest portion of the first bottom sheet of the first roof panel.

6. A roofing structure comprising:
a first roof panel having (a) a first back wall, and (b) a first bottom sheet positioned at an angle, wherein a vertically highest end of the first bottom sheet is attached to the first back wall, wherein the height of the first back wall is a first height;
a second roof panel having (a) a second back wall, and (b) a second bottom sheet positioned at an angle, wherein a vertically highest end of the second bottom sheet is attached to the second back wall, wherein the height of the second back wall is the first height;
a ridge cap; and
a z-clip attached to the back wall of the first roof panel, wherein the z-clip has an overhang that extends away from the back wall of the first roof panel,
wherein the first roof panel and the second roof panel are positioned such that the first back wall of the first roof panel is adjacent to the second back wall of the second roof panel, and
wherein the ridge cap is positioned so as to cover the first back wall of the first roof panel and the second back wall of the second roof panel.

7. The roofing structure of claim 6 , wherein a length of the first bottom sheet is equal to a length of second bottom sheet.

8. The roofing structure of claim 6 , wherein the first bottom sheet is angled at a first slope and the second bottom sheet is angled at a second slope different from the first slope.

9. The roofing structure of claim 6 , wherein an external side of the back wall of the first roof panel is positioned so as to face an external side of the back wall of the second roof panel,
wherein the ridge cap comprises a first pane extending from (a) a first position above a gap between the external side of the back wall of the first roof panel and the external side of the back wall of the second roof panel to (b) a second position that is above the first bottom sheet of the first roof panel, at a vertical height that is lower than the first height, and
wherein the second position is located at a horizontal distance from the back wall of the first roof panel that is sufficient to create a capillary break.

10. The roofing structure of claim 6 , further comprising:
a z-clip attached to the back wall of the first roof panel, wherein the z-clip has an overhang that extends away from the back wall of the first roof panel,
wherein the ridge cap is detachably coupled to the z-clip.

11. The roofing structure of claim 6 ,
wherein the second position is located at a distance from the overhang from the z-clip that is sufficient to create a capillary break.

12. The roofing structure of claim 6 , further comprising:
a z-clip attached to the back wall of the first roof panel, wherein the z-clip has an overhang that extends away from the back wall of the first roof panel,
wherein the ridge cap further comprises a second pane extending from the second position to a third position that is above the first bottom sheet of the first roof panel, at a vertical height that is lower than the vertical height of the second position, and located horizontally closer to the back wall of the first roof panel than the second position,
wherein the second position of the ridge cap is located farther from the back wall of the first roof panel than a termination point of the overhang of the z-clip, and
wherein the third position the ridge cap is located closer to the back wall of the first roof panel than the termination point of the overhang of the z-clip.

13. A roofing structure comprising:
a ridge cap;
a first roof panel having (a) a first bottom sheet positioned at an angle, (b) a first side sheet and a second side sheet, the first side sheet and the second side sheet being positioned at opposite sides of
