Abstract

A steel roofing panel support system is disclosed herein. The system generally includes a support element positioned on a roof surface, the support being configured to support at least a portion of a steel roof panel to be placed thereon. The support element may be cut from a block of expanded polystyrene such that the support is substantially wedge-shaped. A support element as disclosed herein may also be used in installations of steel panels over existing wood shakes or other roof surfaces.

Claims

1. A roofing system comprising:

a steel roof panel having a non-planar shape;

a roof surface;

a wedge-shaped support element having a substantially planar upper surface, and disposed between said roof panel and said roof surface, wherein the shape of the support element is substantially independent of the shape of the roof panel; and

wherein the support element is configured to allow the position of the roof panel to be adjusted laterally, forwards, or rearwards on the support element.

2. The roofing system of claim 1, wherein the support element is made of expanded polystyrene.

3. The roofing system of claim 2, wherein the support element is cut from a block of polystyrene.

4. A roofing system comprising:

a steel roof panel having a non-planar shape;

a roof surface;

a wedge-shaped support element having a substantially planar upper surface, and disposed between said roof panel and said roof surface, wherein the shape of the support element is substantially independent of the shape of the roof panel; and

wherein the roof surface comprises previous roofing tiles.

5. The roofing system of claim 4, further comprising:

a plurality of strips disposed vertically on the tiles;

horizontal battens secure to the top of the strips;

a riser disposed between the strips, and underlying the horizontal battens.

6. A roofing system comprising:

a steel roof panel comprising a longitudinal cross-section with a repeating pattern including a plurality of high points and a plurality of low points;

a roof surface;

means for supporting a central portion of said panel on said roof surface, wherein the means for supporting contacts only the low points of the roof panel

existing roof tiles;

a plurality strips disposed vertically on the tiles;

horizontal battens secure to the top of the strips; and

a riser disposed between adjacent strips, and underlying the horizontal battens.

7. The roofing system of claim 6, wherein the means for supporting comprises a wedge of expanded polystyrene.

8. The roofing system of claim 6, wherein the roof panel comprises a corrugated shape.

9. A method of assembling a roof covering, comprising:

providing a first steel roof panel and a second steel roof panel;

providing a wedge-shaped support element;

placing said support element on a roof surface;

placing said first panel on said support element such that a portion of support element remains exposed;

placing said second panel on said support element such that the exposed portion is covered by the second panel; and

securing said first and second panels and said support element to the roof surface;

wherein the roof panels have a non-planar shape as viewed in a cross-section parallel to a longitudinal axis of the panels.

10. The method of claim 9, wherein the support element is cut from a block of expanded polystyrene.

11. The method of claim 9, wherein the support element provides a thermal resistance rating of at least 4 ft²°

Fh/BTU.

12. The method of claim 9, further comprising, after placing the first panel, adjusting a position of the first roof panel on the support element by moving it laterally, forwards or rearwards.

13. A method of assembling a roof covering, comprising:

providing a first steel roof panel and a second steel roof panel;

providing a wedge-shaped support element;

placing said support element on a roof surface;

placing said first panel on said support element such that a portion of support element remains exposed;

placing said second panel on said support element such that the exposed portion is covered by the second panel; and

securing said panel and said support element to the roof surface;

wherein the roof surface comprises a plurality of existing roof tiles, the method further comprising the steps of;

placing a plurality of strips vertically over a plurality of roof tiles;

placing a riser between adjacent strips;

placing horizontal battens over said strips and said riser.

14. A roofing system comprising:

a steel roof panel;

a roof surface comprising previous roofing tiles;

a wedge-shaped support element having a flat upper surface, and disposed between said roof panel, and said roof surface.

15. The roofing system of claim 14, further comprising:

a plurality of strips disposed vertically on the tiles;

horizontal battens secure to the top of the strips;

a riser disposed between the strips, and underlying the horizontal battens.

16. A roofing system comprising:

a steel roof panel;

a roof surface;

means for supporting a central portion of said panel on said roof surface;

existing roof tiles;

a plurality strips disposed vertically on the tiles;

horizontal battens secure to the top of the strips; and

a riser disposed between adjacent strips, and underlying the horizontal battens.

17. The roofing system of claim 16, wherein the means for supporting comprises a wedge of expanded polystyrene.

18. A roofing system comprising:

a steel roof panel;

a roof surface; and

means for supporting a central portion of said panel on said roof surface;

wherein the roof panel comprises a corrugated shape

wherein the means for supporting comprises a wedge of expanded polystyrene.

19. The roofing system of claim 18, wherein the means for supporting a roof panel underlies a plurality of roof panels.
