Waterproofed uniform slope with dry-lay surface material
A simple rooftop deck over living space is built with a single waterproof shallow slope in one direction to an edge drain. Float this floor over this surface without screws or fasteners. No damage to waterproofing and max UV protection. FLoat plates snap to the bottom of the deck plank to elevate the floor 5/16". A paver grade material is dry-laid over the structural flooring.¹ No sand fill required.
