  • Patent number: 5428931
    Abstract: A system for protecting the exterior surface of a static structure, such as a roof, a wall, a fence or other structure, especially those exterior surfaces that are exposed to the ultra violet rays of the sun, to the elements, to ice damning, and to external mechanical stresses. The system is a laminated construction module including a waterproof substrate material which is substantial completed coated on at least its top surface with an adhesive to which the bottom face of one or more exterior protective elements are secured. The protective element is substantially continuously secured, so that should it become cracked, broken or splintered, the fractured portions of the protective element will remain secured to the top of the substrate material without being displaced, thereby protecting the substrate from the elements, from ice damning, and from ultra violet deterioration.
