FIELD: building, particularly special arrangements or devices in connection with roof coverings.
SUBSTANCE: roof structure comprises roof with de-icing coverings having lower edges supported by lower roof edge and extending downwards for at least 2 cm. Water drain gutters are mounted in lower roof part so that upper de-icing covering edge is installed on water drain gutter surfaces. De-icing coverings are made as resilient assemblies having at least one point located along 3 m roof perimeter and characterized by flexure with respect to line connecting upper and lower edges of not less than 0.2% of covering strip width. Structure is provided with oscillation sources connected with de-icing coverings in points, which provide maximal resilient flexures of outer covering surfaces. Inner surfaces of water drain gutters and adjacent roof zones extending upwards from gutters for at least 10 cm are covered with de-icing material.
EFFECT: prevention of ice formation on lower roof edge surface.
