Sheet metal roofing or siding batten system (10) and standing seam system (30) are disclosed. The batten system (10) comprises pan (11), mounting bracket (16) and batten (23) sections. The standing seam system (30) comprises pan (31) and mounting bracket (32) sections. Both mounting bracket designs include a base (13,33), upwardly extending .legs (15,35), and downwardly extending securing legs (16,36) having inwardly extending protrusions (17,37) used to secure lateral borders (28 and 38,39) of the pans to the brackets. The invention ensures positive interlock of the components while allowing for thermal expansion and variations in pan geometry inherent in metal roofing systems.

Roofing and siding system

A standing seam roofing/cladding system (2) includes elongate pans (4) having first and second lateral edges (6, 8) secured to a support structure (12) by channel brackets (10). The channel brackets each include a base (36) and first and second U-shaped arms (38, 40) defining downwardly opening cavities (42, 44). The lateral edges of the pans each include upwardly extending hems (18, 20), sized and positioned to be housed within the cavities formed by the U-shaped arms. The lateral edges also include generally vertically extending legs (22, 24) extending from the hems. The engagement of the hems within the cavities secures the lateral edges of the pans to the support structure. The upper portions (26, 28; 58, 60) of the legs are mechanically interlocked to form a standing seam (30; 62) thus creating a standing seam joint (45). An optional batten (52) may be used over the standing seam joint if desired.

Standing seam roofing/cladding system

A roofing/cladding system (2) for mounting to a structure (4) includes elongate pans (6) having central portions (32) and lateral edges (8, 10) with U-shaped pockets (24, 26) defining inwardly opening edge recesses (28, 30). The pan also includes legs (34, 36) extending upwardly from the upper part (38, 40) of the pockets. The upper edges (72, 74) of the legs are plain to facilitate bending the pans to cover concave or convex surfaces. A bracket (12), used to hold down the pans at their opposed edges, has a base (14), first, upwardly extending arms (46, 48) and second, downwardly extending arms (50, 52) and defining regions (58, 60) therebetween. The legs of the pans are inserted into the regions. A batten (18), used to cover the joint, has inwardly extending lips (68, 70) which extend into the edge recesses immediately beneath the lower ends of the second arms so that vertical movement of the pans and batten are resisted almost immediately by the engagement of the lower ends of the second legs with the lips of the batten. Also, the upper edges (72, 74) of the legs are positioned at the junctions of the first and second arms to further limit upward movement of the pan.

Roofing/cladding system

A standing seam system includes parallel, elongate panels having first and second upstanding, interconnected edges forming a standing seam. The edges include spaced-apart upstanding portions and outer end portions. The outer end portions are folded together to form a lockseam. The outer surfaces of the lockseam and upstanding portions are generally coplanar to provide a uniform appearance and effectively conceal the lockseam. A portion of the panel between the pan section and the second edge is formed to create an upwardly extending bi-fold interior hem in the space between the first and second edges. This interior hem is engaged by brackets secured to the structure at appropriate positions to anchor the panel to the structure. Since the brackets only extend part way up the edges and do not extend into the lockseam, the lockseam is smoother and much more water tight than it would be otherwise.
