Siding and roofing panels and method for mounting same

A wall or roof covering panel for mounting to a support surface, comprising:

• a front surface including 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 comprising a first flange and an elongated receiving groove opened one of substantially upwardly and substantially downwardly, the elongated receiving groove extending between a first section of the covering section and the first flange and being configured to at least partially receive therein the second marginal edge region of a vertically-adjacent panel with the first section of the covering section being uncovered by the vertically-adjacent panel;
• and
• two side marginal edge regions extending between the first marginal edge region and the second marginal edge region, a side receiving groove extending in a first one of the side marginal edge regions and being defined between a first side flange and a first side section of the covering section overlapping at least partially the first side flange and a second one of the side marginal edge regions comprises a second flange entirely insertable in the side receiving groove of a horizontally-adjacent panel and covered by the first side section of the covering section of the horizontally-adjacent panel when inserted in the side receiving groove, the first side section of the covering section being uncovered when the second flange is inserted in the side receiving groove of the horizontally-adjacent panel and a second side section of the covering section, adjacent to the second flange, abutting the first side section of the covering section of the horizontally adjacent panel.

A wall or roof covering panel securable to a support surface, comprising:

• a front surface including a covering section with simulated building elements,
• an opposed rear surface facing the support surface when secured thereto,
• a first marginal edge region, an opposed second marginal edge region, and two side marginal edge regions extending between the first marginal edge region and the second marginal edge region,
• wherein a first one of the side marginal edge regions comprises a side receiving groove defined between a first side flange and a first side section of the covering section with the covering section being aligned with or extending past the first side flange along a vertically-extending side edge of the panel and a second one of the side marginal edge regions comprises a second flange entirely insertable in the side receiving groove of a horizontally-adjacent panel and being entirely covered by the first side section of the covering section with the first side section being exposed outwardly when the second flange is inserted in the side receiving groove of the horizontally-adjacent panel and a second side section of the covering section, adjacent to the second flange, abutting the first side section of the covering section of the horizontally adjacent panel.
