Abstract: A roof element and a process for the production of a roof element are provided, which may have the steps of providing a polymer mixture; admixing an organosiloxane compound with the polymer mixture; a mixing of the polymer mixture, with the organosiloxane compound admixed, with an isocyanate compound to give a polyurethane material and introduction of the polyurethane material into a mold cavity of a foaming mold in a manner such that the polyurethane material reacts to completion and a molded section of the roof element is shaped in the mold cavity wherein the organosiloxane compound is accumulated at the surface of the molded section, wherein in a surface layer of thickness from 0.5 μm to 20 μm of the molded section, the organosiloxane compound is accumulated; and demolding of the roof element from the foaming mold.
