We study the surface roughness of adhesive tape peeled in stick-slip. We find two regions: a smooth surface region associated with fast crack propagation and a rough surface region associated with slow crack propagation. In both regions the surfaces may be self-affine fractal-like with the fractal dimension Df≈2.3. This fractal dimension is typical for surfaces produced by crack propagation, but unexpected in the present case.
