You can easily get *root* page this way:

        $GLOBALS['TSFE']->getPageAndRootline();
        $res = $GLOBALS['TSFE']->getStorageSiterootPids();
        if (is_array($res) && isset($res['_SITEROOT'])) {
            $siteroot_uid = $res['_SITEROOT'];
        }

For "any page" you can walk through $GLOBALS['TSFE']->rootLine array.
You still have to call $GLOBALS['TSFE']->getPageAndRootline() first.

Btw, $GLOBALS['TSFE']->getPageAndRootline() is marked as private but it
is very convinient to use. Not sure why it was marked as private.

Dmitry.
