We study even unimodular Euclidean lattices in dimension 32 with small root systems. It is shown that such lattices are generated by the vectors $\nu$ with $(\nu,\nu)\leqslant4$. For lattices without roots we obtain special properties of the configuration of minimal vectors which are reminiscent of strongly regular graphs.
