Abstract: A deck covering apparatus for selectively covering a portion of a deck from the elements. The deck covering apparatus includes a pair of support assemblies each having a base portion and a rail member. The base portion is designed for coupling to a support structure. The rail member is coupled to the base portion whereby the base portion of each of the support assemblies is designed for supporting the rail member of an associated one of the support assemblies in a spaced relationship above the deck. Each of a plurality of panel assemblies is slidably coupled to the rail member of each of the support assemblies. Each of the panel assemblies is slidably positionable along a length of the rail member of each of the support assemblies whereby each of the panel assemblies are designed for covering a portion of the deck from the elements.
