Abstract: The invention concerns a material for producing built-up roofing, comprising a textile support (T) covered, on one of its faces, with a surface layer (4) closely bound thereto, and consisting of a synthetic resin, said surface layer (4) being based on thermoplastic resins selected from the family of polyolefins, capable of being produced in sheet. The invention is characterized in that said surface layer (4) is based on ethylene polymers or copolymers, its combination with the textile support (T) being obtained by calendering, the latter being embedded over part of its thickness inside the resin layer (4).
