Options[Root]
(Information[Evaluate[#1[[1]]]] & ) /@ %;

{ExactRootIsolation -> False}
"ExactRootIsolation is an option for Root, which specifies whether
exact isolating intervals rather then numeric approximations should be
used to identify algebraic numbers."
Attributes[ExactRootIsolation] = {Protected}

Can someone provide me more information about this undocumented option
of Root with some examples of the setting ExactRootIsolation ->True?

Thanks
