If you have a rooted stock rom, you will be able to receive update notifications from Sony and you can update using the offical methods.
However, the update will install the new stock rom without root, as this is not supported by the manufacturer.
There are some tricks to maintain root during an update, but there is no guarantee it will work.

FYI, for the current 4.3 stock release for V and T, there is a "one-click" root method.
