A roofing system and kit including a texture layer for application to an upper surface of the deck of the roof with an upper face of the texture layer being contoured to resemble a different roofing material, a transition texture strip for positioning across gaps between texture layer occurring at transitions in the upper surface of the roof deck and having a contoured upper surface, and an edge strip for application along the perimeter edges of the roof to create an outer perimeter for the roofing system. A finish layer is applied to the texture layer, transition texture strip and edge strip positioned on the roof deck in a liquid sprayable form as a coating onto the texture layer, transition texture strip and edge strip to solidify into a solid layer such that the finish layer forms a continuous membrane over the texture layer, transition texture strip and edge strip.
