Interlocking panels having a decorative pattern thereon and having a system of interlocks for providing a weatherproof covering system for use as roofing, siding and the like. The panels may be of a readily formed material such as a thermoplastic having a decorative pattern thereon complimentary to the pattern on adjacent panels to provide a continuous decorative roofing or siding panel system. The panels have a simple hook-like region adjacent the upper edge thereof, just below the nail line retaining the panel to the roof, to receive and retain the lower edge of the panels of the next higher course in a manner so as to eliminate the otherwise exposed nailheads. Decorative patterns simulating conventional materials such as shake may be impressed into the panels by vacuum forming and/or other manufacturing techniques. Use of a staggered panel side provides for a substantially hidden junction between sidewise adjacent panels to provide a continuous and unbroken pattern. By dropping the regions separating individual simulated shake to the basic roof plane, maximum panel stability and registry onto the roof surface, as well as enhanced visual characteristics, are achieved.
A panel for use in plurality to simulate wood shake covering an area, comprising a panel member formed from a unitary sheet of thermoplastic having upper, lower and first and second side edges, and having an area therebetween with the desired three dimensional decorative pattern on the top surface thereof simulating a plurality of individual wood shake, said decorative pattern including a hollow raised portion at least adjacent said first side edge thereof, said unitary sheet having a first planar region above said three-dimensional decorative pattern for lying flat against a surface to be covered, and a second region extended between said first planar region and said upper edge of said unitary sheets, said second region being folded through approximately 180.degree. to overlie said first planar region to define a slot adjacent and facing the top of said decorative pattern with a double thickness nailing flange thereabove, said double thickness nailing flange being defined by a portion of said second region immediately overlying and substantially in face to face abutment with a portion of said first planar region, the remainder of said second region being formed to only overlie the first planar region with a space therebetween which is substantially unaffected by the passing of nails through said nailing flange during installation of the panels, said bottom edge of said unitary sheet being curved under to define a lip adjacent and under the lower region of said panel approximately parallel to said first planar region, said slot being proportioned to receive and retain at least a portion of the lip of a similar decorative panel, said panel member further having a raised portion adjacent said second side edge thereof, complimentary to said hollow raised portion adjacent said first side edge, whereby said first side edge of one panel may overlie the second side edge of another panel to provide a decorative pattern extending across both panels with a moisture barrier therebetween, at least one end of said slot in each panel terminating short of the adjacent edge of said panel so that the slots in adjacent panels cooperate to provide a slot of substantially uniform elevation across adjacent panels, and at least one end of said lip also terminating short of the adjacent edge of said panel so that the lips in adjacent panels are substantially colinear to mate with the slots defined by similar panels in a lower course in any desired staggered relationship.
A decorative panel for use in plurality to simulate wood shake covering an area comprising a unitary sheet of thermoplastic, said sheet having upper, lower and first and second side edges, and having a substantial decorative portion therebetween formed away from a base plane to simulate a plurality of individual shake arranged in a plurality of courses and defining a hollow raised portion adjacent said first side edge of said sheet, said sheet being folded upward through approximately one hundred eighty degrees to provide a slot adjacent the top of and facing said decorative portion with a double thickness flange-like extension in said base plane extending between said slot and the upper edge of the panel, said double thickness nailing flange being defined by a portion of said sheet immediately overlying and substantially in face to face abutment with another portion of said sheet, the portion of said sheet defining said slot being formed to only overlie the adjacent region of the sheet with a space therebetween which is substantially uneffected by the passing of nails through said nailing flange during installation of the panels, the lower portion of said sheet being folded under to form a lip under the lower part of the decorative portion and approximately parallel to said flange like extension, said slot being proportioned to receive and retain at least a portion of the lip of a similar decorative panel, the edges of said simulated shake in at least two courses adjacent said first side edge of said sheet being staggered, said sheet further having a raised portion adjacent said second side edge thereof complimentary to said hollow raised portion adjacent said first side edge, whereby said first side edge of one panel may overlie the second side edge of another panel to provide a decorative pattern extending across both panels with a moisture barrier therebetween, and a flange-like region extending between said hollow raised portion adjacent said second side edge and said second side edge, at least one end of said slot in each panel terminating short of the adjacent edge of said panel so that the slots in adjacent panels cooperate to provide substantially colinear slots across adjacent panels, and at least one end of said lip also terminating short of the adjacent edge of said panel so that the lips in adjacent panels are substantially colinear to mate with the slots defined by similar panels in a lower course in any desired staggered relationship.
