Roofing panel

Abstract

A pre-manufactured roofing panel includes a joint having a first and a second edge that form a locking joint. The first edge includes a longitudinal protrusion extending outwardly from first edge. The protrusion has a generally trapezoidal cross-sectional shape. The second end includes a longitudinal cavity. The cavity has a generally inverse trapezoidal cross-sectional shaped substantially corresponding to the size and shape of the protrusion. The unique shape of the protrusion and cavity greatly facilitates the alignment of the two edges and reduces the likelihood of damage to either edge. The panel also includes a ribbed gasket disposed along an outer edge that seals any voids created by imperfections in the panels. The gasket is installed at the factory, and includes a polyethylene foam gasket.

       14 . The panel as claimed in  claim 9  wherein an inner surface of said panel proximate said first and said second edge portions includes a beveled region disposed along said first and said second longitudinal axes of said first and said second edge portions.  
   
   
       15 . The panel as claimed in  claim 14  wherein said first member includes an outer support surface, a plurality of framing supports secured to said outer support surface, insulation disposed between said plurality of framing supports, and a plurality of inner skins wherein said plurality of inner skins form said inner surface of said panel.  
   
   
       16 . A paneling kit comprising: 
 a plurality of generally rectangular panels including: 
 an inner and an outer generally parallel and generally planar surface;  
 a first edge region having a first longitudinal axis and first transverse axis, said first transverse axis disposed generally perpendicular to a longitudinal axis of said inner and said outer surface, said first edge region including a protrusion disposed along said first longitudinal axis and having a generally trapezoidal cross-sectional shape extending substantially perpendicular to said first longitudinal axis; and  
 at least a second edge region having a second longitudinal axis disposed substantially parallel to said first longitudinal axis and second transverse axis disposed generally perpendicular to said longitudinal axis of said inner and said outer surface, said second edge region including a cavity disposed substantially along said second longitudinal axis, said cavity having a generally trapezoidal cross-sectional shape and sized and shaped to friction engage said protrusion such that when a protrusion of a first panel is inserted into an adjacent panel said panels are substantially locked together and form a generally planar inner and outer surface.
