Abstract
Abstract A sheet metal roofing/siding system for application on the sheathing substrate of a building wall or roof structure comprising an elongated joint strip secured to said structure in combination with a pair of elongated panel members interlocked with the joint strip to form a watertight cover. The elongated joint strips are secured to the sheathing substrate of the building structure in parallel, spaced apart configuration and the panel members are interlocked with the joint strips along upper and lower marginal edges to provide a lap siding type appearance which is watertight and easy to install and apply.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
163 words
A sheet metal roofing and siding system for application on the sheathing substrate of a building structure comprising an elongated continuous joint strip adapted to be secured to said substrate and at least one elongated sheet metal panel interlockable with said joint strip, said panel including marginal edge portions folded in opposite directions, one edge portion extending downwardly and inwardly and an outer edge portion extending upwardly and inwardly to define reverse bends for interlocking engagement with said joint strip, said joint strip including a leg extending transversely outward of said substrate and having an exteriorly exposed surface, said leg including structure along the lower edge defining a channel opening in a first direction for interlocking engagement with the upwardly and inwardly folded marginal edge portion along one edge of a panel, said leg including an Upper flange along an upper edge extending transversely and outwardly thereof for interlocking engagement with the folded marginal edge portion along an edge of an adjacent panel.
Claim 2
Dependent Claim
163 words
A sheet metal roofing and siding system for application on the sheathing substrate of a building structure comprising an elongated continuous joint strip adapted to be secured to said substrate and at least one elongated sheet metal panel interlockable with said joint strip, said panel including marginal edge portions folded in opposite directions, one edge portion extending downwardly and inwardly and an outer edge portion extending upwardly and inwardly to define reverse bends for interlocking engagement with said joint strip, said joint strip including a leg extending transversely outward of said substrate and having an exteriorly exposed surface, said leg including structure along the lower edge defining a channel opening in a first direction for interlocking engagement with the upwardly and inwardly folded marginal edge portion along one edge of a panel, said leg including an Upper flange along an upper edge extending transversely and outwardly thereof for interlocking engagement with the folded marginal edge portion along an edge of an adjacent panel.
Claim 3
Dependent Claim
163 words
A sheet metal roofing and siding system for application on the sheathing substrate of a building structure comprising an elongated continuous joint strip adapted to be secured to said substrate and at least one elongated sheet metal panel interlockable with said joint strip, said panel including marginal edge portions folded in opposite directions, one edge portion extending downwardly and inwardly and an outer edge portion extending upwardly and inwardly to define reverse bends for interlocking engagement with said joint strip, said joint strip including a leg extending transversely outward of said substrate and having an exteriorly exposed surface, said leg including structure along the lower edge defining a channel opening in a first direction for interlocking engagement with the upwardly and inwardly folded marginal edge portion along one edge of a panel, said leg including an Upper flange along an upper edge extending transversely and outwardly thereof for interlocking engagement with the folded marginal edge portion along an edge of an adjacent panel.
Claim 4
Dependent Claim
163 words
A sheet metal roofing and siding system for application on the sheathing substrate of a building structure comprising an elongated continuous joint strip adapted to be secured to said substrate and at least one elongated sheet metal panel interlockable with said joint strip, said panel including marginal edge portions folded in opposite directions, one edge portion extending downwardly and inwardly and an outer edge portion extending upwardly and inwardly to define reverse bends for interlocking engagement with said joint strip, said joint strip including a leg extending transversely outward of said substrate and having an exteriorly exposed surface, said leg including structure along the lower edge defining a channel opening in a first direction for interlocking engagement with the upwardly and inwardly folded marginal edge portion along one edge of a panel, said leg including an Upper flange along an upper edge extending transversely and outwardly thereof for interlocking engagement with the folded marginal edge portion along an edge of an adjacent panel.
Claim 5
Dependent Claim
71 words
The system of claim 1, including a pair of said joint strips in spaced parallel relation, one of said panels interlocked along its lower inwardly folded marginal edge portion with the upper flange of a lower one of said joint strips, the upper inwardly folded marginal edge portion of said one panel interlocked with the channel along the lower edge of the leg of the upper one of said joint strips.
Claim 6
Dependent Claim
30 words
The system of claim 1 wherein said joint strip is of generally channel-shaped cross section and includes a second leg spaced from said first mentioned leg by a bight portion.
Claim 7
Dependent Claim
30 words
The system of claim 3 wherein said second leg includes a flange along the lower edge transverse thereof for bearing against the substrate on which said joint strip is mounted.
