ROOFING AND SIDING SYSTEMS
Embodiments of the present invention provide improved metal roofing and siding systems. In one aspect of the invention, a roofing or siding system configured to be positioned against a structure is provided. The roofing or siding system includes a first panel including a female locking element opening away from the structure when positioned thereon; a second panel including a male locking element directed toward the structure when positioned thereon; and an anchor bar configured to be attached to the structure, wherein the anchor bar defines an channel directed away from the structure which is configured to engage the male locking element and defines a flange directed towards the structure that is configured to engage the female locking element.
1 . A roofing or siding system configured to be positioned against a structure comprising:
a first panel including a female locking element opening away from the structure when positioned thereon;
a second panel including a male locking element directed toward the structure when positioned thereon; and
an anchor bar configured to be attached to the structure, wherein the anchor bar defines a channel directed away from the structure which is configured to engage the male locking element and further defines a flange directed towards the structure that is configured to engage the female locking element.
2 . The roofing or siding system of claim 1 , wherein the female locking element comprises a hem section formed in a substantially U-shape.
3 . The roofing or siding system of claim 1 , wherein the male locking element comprises a hem section.
4 . The roofing or siding system of claim 1 , wherein the first panel has an elongate shape having an elongate length and a first and second lateral edge and wherein further, the female locking element is positioned proximate the first lateral edge.
5 . The roofing or siding system of claim 4 , wherein the anchor bar is an elongate structure having an elongate length substantially the same as the elongate length of the first panel.
6 . A roof panel or siding panel system configured to be positioned against a structure comprising:
a first panel having a first lateral edge portion extending upwardly relative to the structure when the first panel is positioned thereon, wherein the first lateral edge portion includes a groove portion and an inclined portion; and
a second panel having a second lateral edge portion that includes a first leg portion extending upwardly relative to the structure when the second panel is positioned thereon, and a second leg portion which is substantially parallel with the first leg and terminates in a lock flange directed towards the first leg portion,
wherein the first and the second panels are configured to be adjacently positioned, and wherein the second lateral edge portion of the second panel is configured to receive the first lateral edge portion of the first panel between the first and the second leg portions such that the lock flange engages the groove portion.
7 . The roof panel or siding panel system of claim 6 , wherein the first leg portion and the second leg portion are jointed by a U-shaped section.
8 . The roof panel or siding panel system of claim 6 , wherein the first lateral edge portion includes a female locking element opening away from the structure when positioned thereon.
9 . The roof panel or siding panel system of claim 6 , wherein the second lateral edge portion includes a male locking element directed toward the structure when positioned thereon.
10 . The roof panel or siding panel system of claim 6 further comprising an anchor bar configured to be attached to the structure and to discourage movement of the first and second panels.
11 . A roofing or siding system for attachment to a structure comprising:
an elongate panel having two opposing lateral edge portions and an intermediate portion between the opposing lateral edges wherein the intermediate portion has a substantially convex shape when the panel is positioned on the structure; and
a pair of anchor bars, each having an engagement element configured to engage a lateral edge portion of the roofing panel and wherein the pair of anchor bars are attached to the structure wherein the pair of anchor bars are substantially parallel and spaced apart a predetermined distance such that the intermediate portion remains convex when the panel is engaged by the pair of anchor bars.
12 . The roofing or siding system of claim 11 , wherein one of the two opposing lateral edge portions includes a female locking element opening away from the structure when positioned thereon.
13 . The roofing or siding system of claim 11 , wherein the female locking element comprises a hem section formed in a substantially U-shape.
14 . The roofing or siding system of claim 12 , wherein the other of the two opposing lateral edge portions includes a male locking element directed toward the structure when positioned thereon.
15 . The roofing or siding system of claim 14 , wherein the male locking element comprises a hem section.
16 . The roofing or siding system of claim 14 , wherein each of the pair of anchor bars define a channel directed away from the structure and a flange directed towards the structure.
17 . The roofing or siding system of claim 11 , wherein one of the lateral edge portions extends upwardly relative to the structure when the elongate panel is positioned thereon, and wherein the one of the lateral edge portions defines a groove portion.
18 . The roofing or siding system of claim 17 , wherein another of the lateral edge portions includes a first leg portion that extends upwardly relative to the structure when the panel is positioned thereon, and transitions into a second downwardly directed second leg portion that terminates in an locking flange directed toward the first leg portion.
