FIELD: construction engineering, particularly, roofing material prepared at construction sites. SUBSTANCE: roof material presents multilayer material consisting of alternating layers of binder and base. Binder is applied by spraying it in molten state or in the form of emulsion. Base is used in the form of fragments (flakes, petals, shreds) of flexible sheet material by scattering in movable shaft from optimal height. Fragments of base moving at random in air are uniformly distributed on cover. Amount of fragments is taken with 25% excess to obtain their mutual overlapping. EFFECT: reduced manual labor and provided spatial compatibility of roofing material with curved surface of base. 1 dwg
