You’ll want to setup a child theme:

https://startupwp.com/topic/child-theming/

Then copy over header.php from your parent theme. In your theme options you’ll want to choose the logo option. Then find the following in header.php:

<?php
if (!is_singular()) {echo '<h1>';}
echo '<a href="'.home_url().'/" title="'.esc_attr(get_bloginfo('name')).'" rel="home">';
if ($options['logo']!="")
echo '<img src="'.esc_url($options['logo']).'" alt="'.esc_attr(get_bloginfo('name')).'" id="logo" />';
else
echo esc_html(bloginfo( 'name' ));
echo '</a>';
if (!is_singular() ) {echo '</h1>';} ?>

Either above or below this block of code, you’ll want to add:

<h1>Your Site Title</h1>
