Aqueous roof coating compositions contain an aqueous dispersion of a vinyl acetate ethylene copolymer obtained by polymerizing by aqueous emulsion polymerization, in the presence of one or more emulsifiers, of



a) 50 to 90% by weight of vinyl acetate,
b) 2 to 45% by weight of ethylene, and
c) 0.1 to 10% by weight of at least one functional comonomer which is an ethylenically unsaturated acid or salt thereof, an ethylenically unsaturated carboxamide, or an ethylenically unsaturated silane monomers, and optionally
d) 0 to 35% by weight of copolymerizable ethylenically unsaturated non-functional comonomers, based on the total weight of the monomers and fillers and optionally pigments.
