The GC never builds a tree. It marks the roots and puts them on a worklist. Then it loops pulling an item off the worklist, tracing all pointers, and putting all newly found objects on the worklist. This loop is done concurrently with program execution. See the long comment at the top of runtime/mgc.go.
