Abstract: A wall or roof covering for mounting to a support surface, comprising: a plurality of panels securable to the support surface, each of the panels having a front surface comprising a covering section with simulated building elements, an opposed rear surface facing the support surface when secured thereto, a first marginal edge region and an opposed second marginal edge region, the first marginal edge region having an elongated receiving groove with an elongated aperture oriented one of substantially upwardly and substantially downwardly, the second marginal edge region being at least partially insertable in the first elongated receiving groove of a vertically-adjacent panel and being at least partially covered by a first section of the covering section of the vertically-adjacent panel when inserted therein.

Abstract: A corner assembly for siding and roofing coverings includes two complementary corner molding members, each one of the two corner molding members having a front wall including a covering section with simulated building elements on an outer face thereof. Each one of the two corner molding members further has at least one protruding finger and at least one recess. The at least one protruding finger and at least one recess are configured in an alternate configuration in order to interlock in a male-female configuration when the two complementary corner molding members are engaged with one another to define a corner. A method covers a length of a corner defined at a junction of a first support surface and a second support surface.
