Call to undefined function roots_template_path() error

I’m trying to create a single page for a custom post type.

use Roots\Sage\Setup;
use Roots\Sage\Wrapper;

<!doctype html>
<html <?php language_attributes(); ?>>
<?php get_template_part('templates/head'); ?>
<body <?php body_class(); ?>>
<!--[if IE]>
  <div class="alert alert-warning">
    <?php _e('You are using an <strong>outdated</strong> browser. Please <a href="">upgrade your browser</a> to improve your experience.', 'sage'); ?>
<!-- Google Tag Manager (noscript) -->
<noscript><iframe src=""
height="0" width="0" style="display:none;visibility:hidden"></iframe></noscript>
<!-- End Google Tag Manager (noscript) -->
<div class="wrap container body" role="document">
  <div class="content row">
    <main class="main">
      <?php include roots_template_path(); ?>
    </main><!-- /.main -->
    <?php if (Setup\display_sidebar()) : ?>
      <aside class="sidebar">
        <?php include Wrapper\sidebar_path(); ?>
      </aside><!-- /.sidebar -->
    <?php endif; ?>
  </div><!-- /.content -->
</div><!-- /.wrap -->

<script type="text/javascript" src=""></script>
<div class="mobile-booking">
  <a href="">Book Now</a>

This is my code on my base-single-rooms.php but when I run this it fires an php error.
