Abstract
Abstract A roofing or siding panel and assembly method making use of panels each comprising a base strip (e.g., plywood) and a strip of surfacing material (e.g., composition). The strip of surfacing material has one margin secured to the underside of the base strip. When assembled on a roof structure or side wall, the lower horizontal margin of one base strip overlaps the upper horizontal margin of the next lower strip, and the composition surfacing strip that is attached to the one base strip extends downwardly from the region of the overlap to cover the upper side of the next lower base strip. The lower horizontal edge of each base strip is of substantial thickness to provide aesthetic shadow lines. Preferably the base strips provide sufficient structural strength to serve as sheathing.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
187 words
An assembly of panels forming a roof or siding for the outer side of a building structure, each of the panels comprising a base strip of substantial thickness and strength adapted to be secured to a supporting structure to form structural sheathing, and a planar strip of waterproof surfacing composition having an upper margin of the same secured to the inner side of the base strip along the lower margin of the same, one panel in the assembly having the lower margin of its base strip overlapping the upper margin of the base strip of the next lower panel, with the upper margin of the surfacing composition interposed between the overlapping margins of the base strips, and with the surfacing composition of said one panel overlying and covering and secured to the outer side of the next lower base strip and terminating at the lower edge of the same, the upper surfaces of the composition extending between the lower horizontal edges of the base strips being exposed to the weather and the contiguous lower horizontal edges of the base and composition strips forming horizontally extending shadow lines.
Claim 2
Dependent Claim
187 words
An assembly of panels forming a roof or siding for the outer side of a building structure, each of the panels comprising a base strip of substantial thickness and strength adapted to be secured to a supporting structure to form structural sheathing, and a planar strip of waterproof surfacing composition having an upper margin of the same secured to the inner side of the base strip along the lower margin of the same, one panel in the assembly having the lower margin of its base strip overlapping the upper margin of the base strip of the next lower panel, with the upper margin of the surfacing composition interposed between the overlapping margins of the base strips, and with the surfacing composition of said one panel overlying and covering and secured to the outer side of the next lower base strip and terminating at the lower edge of the same, the upper surfaces of the composition extending between the lower horizontal edges of the base strips being exposed to the weather and the contiguous lower horizontal edges of the base and composition strips forming horizontally extending shadow lines.
Claim 3
Dependent Claim
23 words
An assembly as in claim 1 in which the surfacing composition of each panel has the same general configuration as the base strips.
Claim 4
Dependent Claim
28 words
An assembly as in claim 2 in which the base strips are plywood, the lower exposed edges of the base strips being sealed against moisture by a sealant.
