FIELD: process engineering.
SUBSTANCE: invention relates to roof protection against formation of icicles on its edges. Proposed method consists in application of hydrophobic coating on roof surface. Note here that coating with limiting wetting angle of over 120° is selected. Hydrophobic coating is applied in strips with their width making at least 50 mm, seeing from the edge. Water drop on surface is ball shaped to roll on roof surface with no wet traces. Boundary layer disappears on such surface.
EFFECT: higher repellent properties.
