For a family of group words $w$ we show that if $G$ is a profinite group inwhich all $w$-values are contained in a union of finitely many subgroups with aprescribed property, then $w(G)$ has the same property as well. In particular,we show this in the case where the subgroups are periodic or of finite rank. If$G$ contains finitely many subgroups $G_1,G_2,...,G_s$ of finite exponent $e$whose union contains all $\gamma_k$-values in $G$, it is shown that$\gamma_k(G)$ has finite $(e,k,s)$-bounded exponent. If $G$ contains finitelymany subgroups $G_1,G_2,...,G_s$ of finite rank $r$ whose union contains all$\gamma_k$-values, it is shown that $\gamma_k(G)$ has finite $(k,r,s)$-boundedrank.
