The intense waste generation moved by the urban and industrial activity and the wastefulconsumption of natural resources, encourage the development of new technologies for theutilization of wastes and its reuse in new industrial processes, which decreases the environmentalpollution and the removal of virgin materials. In this sense we work in the development of newmaterials and components from urban and industrial waste prepared by different techniques andwith various applications.We work on the development of a composite material made with recycled rubber from tires out ofuse (NFU) and recycled polyethylene, linked through the fusion of the plastic and the subsequentpressing of the material. In this article we present the partial results obtained in the physical andmechanical testing of the roof tiles, and the burning behavior of the components manufactured withflame retardants additives available in the market, to comply with the regulations in order to usethese housing components. These components have as main advantages the high resistance toflexion and the hard impact, low thermal conductivity, and low water absorption by immersion inwater. Despite the fact that the components do not meet all the points of the reference Norm inregard to its behavior when exposed to fire, further amendments in the formulation and themanufacture process have shown interesting results, with which roof tiles could comply with theregulation for the use proposed.We developed a sustainable covering system for roof using two types of wastes in great abundancein all urban sites, which involve a simple manufacture process. Besides, due to its high flexibilityand resistance to impact hard is presented as a good constructive alternative for housing covering inareas affected by the fall of hail or by the risk of blowing up and deterioration by strong winds.
