A panel assembly ( 40 ) that addresses oil canning when installed over a substrate or deck ( 72 ) is disclosed. The panel assembly ( 40 ) includes a panel ( 42 ). The panel ( 42 ) includes a first primary panel surface ( 44 ) that faces the substrate ( 72 ) in the installed configuration, as well as a second primary panel surface ( 46 ) that faces away from the substrate ( 72 ) in the installed configuration. Another component of the panel assembly ( 40 ) is a first structure ( 60 ) that is disposed between the panel ( 42 ) and the substrate ( 72 ). Typically, either a first surface ( 62 ) of the first structure ( 60 ) is chemically bonded directly to the first primary panel surface ( 44 ) such that an interface between the first surface ( 62 ) and the first primary panel surface ( 44 ) includes a chemical bond, or a second surface ( 64 ) is chemically bonded directly to the substrate ( 72 ) such that an interface between the second surface ( 64 ) and the substrate ( 72 ) includes a chemical bond. In any case, the first structure ( 60 ) produces a convexity on the second primary panel surface ( 46 ) to address oil-canning effects or stress wrinkling of the panel ( 42 ).
