FIELD: construction engineering. SUBSTANCE: this relates to waterproofing materials and can be used in arrangement of roofs of civic and industrial buildings and structures. It is also suitable for construction of floor coverings. Rolled roofing material contains protective course made up of composition based on thermosoftening plastics from line of polyolefins and rubber crumbs with addition of at least pigment and technological additives. Also included in material is liner consisting of composition based on thermosoftening plastics and crumbles similar to those used in protective course. Ratio of thickness of protective course and of liner is equal to 1: 3. Method for manufacture of rolled roofing material is based on ratio of ingredients in composition used in protective course and also is based on formation of rolled blank of protective course according to calendering technology. After manufacturing of protective course, similar procedure is used for formation of rolled blank for liner. Protective course which was manufactured and preliminarily heated is combined with liner in process of calendering of liner. After that, both courses are doubled. Aforesaid roofing material is of high quality and less expensive and can be manufactured at high productive capacity. EFFECT: higher efficiency. 3 cl, 1 dwg, 1 tbl
