class RootCategoryIds extends \Magento\Framework\View\Element\Template
{
    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        \Magento\Store\Model\StoreManagerInterface $storeManager,
        array $data = []
    ) {
        $this->_storeManager = $storeManager;
        parent::__construct($context, $data);
    }

    /**
     * Return ids of root categories as array
     *
     * @return array
     */
    public function getRootIds()
    {
        $ids = [\Magento\Catalog\Model\Category::TREE_ROOT_ID];
        foreach ($this->_storeManager->getGroups() as $store) {
            $ids[] = $store->getRootCategoryId();
        }
        return $ids;
    }

Call from template file,

echo "<pre>";print_r($this->getRootIds());

Output as array,

Array
(
    [0] => 1
    [1] => 2
    [2] => 42
)

In above case 1 is for Root Catalog id,
2 is your Default Category id.
