Abstract. We obtain a formula for the essential spectral radius of transfer-type operators associated with families of C^(1+delta) diffeomorphisms of the line and Zygmund, or H\"older, weights acting on Banach spaces of Zygmund (respectively H\"older) functions. In the uniformly contracting case the essential spectral radius is strictly smaller than the spectral radius when the weights are positive.
