We investigate the surface roughness influence on the gain from parametric amplification in nanoresonators in presence of thermomechanical and momentum exchange noise. The roughness is characterized by the rms amplitude w, the correlation length X, and the roughness exponent 0>Qgas, the influence of surface roughness on the gain strongly diminishes.
