Abstract: A roof flashing for or suitable for flashing a “ridgeline” as herein defined, the flashing being of multiple materials and being at least in part laminated and comprising or including a “ridge” overlying region to overlie the actual or phantom “ridge” to be flashed, the ridge being as herein defined, a first flanking region extending from the ridge overlying region, and a second flanking region extending from the ridge overlying region, wherein the ridge overlying region is conformed to a retainable three dimensional form and/or is conformable and can retain to a three dimensional form, and wherein the first and second flanking regions extend from the ridge overlying region so as to flank the actual or phantom “ridge” to be flashed by the flashing, and wherein there is a weathering surface of one or more weathering material(s) and at least one of the flanking regions has at least a partial underlying support of the weathering material(s).

Abstract: A building cladding has a cladding material (6) which is fusible and which attached to fastening (7) by fusing. The fastening penetrating the building substrate (4). By fusion to itself the cladding material forms a generally continuous membrane over the substrate. Preferably polyurethane is used as the cladding material fusible surface.
