@friarpaul: For this you’ll need to create a child theme. You can find more details on creating child theme HERE. Then in your child theme’s functions.php add the following codes.
add_action('init', 'catchbase_child_move_header_right_sidebar_above_site_title');
function catchbase_child_move_header_right_sidebar_above_site_title() {
	remove_action( 'catchbase_header', 'catchbase_site_branding', 40 );
	remove_action( 'catchbase_header', 'catchbase_header_right', 50 );
	add_action( 'catchbase_header', 'catchbase_header_right', 40 );
	add_action( 'catchbase_header', 'catchbase_site_branding', 50 );
}
Go to Dashboard=> Appearance=> Customize=> Theme Options=> Custom CSS box and add the following CSS:
.sidebar-header-right, .sidebar-header-right .widget-wrap {
    float: none;
}
