Hi HecKel:
For the root > you could actually just add it to the Code Inserter Module for insertion into the head tag, but, we have not integrated this into SEO Ultimate on a page by page basis.
Add your language and it should work fine <link rel="alternate" href="http://example.com" hreflang="en-us=" />

This is a great idea though so, we can add this as a new feature once we burn through the backlog.
All the best,
Jeffrey
You can add hreflang tag easily by using this plugin https://wordpress.org/plugins/language-selector-related/
see the example..visit this site http://www.viduweb.com.au/about-us/
and check source code
<link rel=”alternate” href=”http://www.viduweb.com.au/about-us/” hreflang=”en-au” />
<link rel=”alternate” href=”http://www.viduweb.com/about-us/” hreflang=”x-default” />
