FIELD: construction. SUBSTANCE: material for roofs with laminar structure in which layer of stress-absorbing and stabilizing plastic material is fully coated on one of its sides and, at least, partially coated on its other side, preferably, with sheets of metallic foil, for instance, sheets of aluminum foil made with formation of density located flat folded sections whose shape, for instance, in form of closed opposite folds, such that outer part of material of each folded section will come in contact with stress-absorbing and stabilizing layer only in case of unfolding of folded section in connection with deformation of water-proofing material with the aim of its improved fitting to roof. EFFECT: higher efficiency. 8 cl, 2 dwg
