Roots: Custom Post Type 404 Not Found

So I'm trying to create a custom post type for my theme. I've written the function to register the post type and I can add a post from the admin panel, but when I try to view the new post's permalink, I get a 404 not found page.

Here's my post type function:

add_action( 'init', 'create_press_coverage' );

function create_press_coverage() {
    register_post_type( 'press_coverage',
        array(
            'labels' = array(
                'name' = 'Press Coverages',
                'singular_name' = 'Press Coverage',
                'add_new' = 'Add New',
                'add_new_item' = 'Add New Press Coverage',
                'edit' = 'Edit',
                'edit_item' = 'Edit Press Coverage',
                'new_item' = 'New Press Coverage',
                'view' = 'View',
                'view_item' = 'View Press Coverage',
                'search_items' = 'Search Press Coverage',
                'not_found' = 'No Press Coverages found',
                'not_found_in_trash' = 'No Press Coverages found in Trash',
                'parent' = 'Parent Press Coverage'
            ),

            'public' = true,
            'menu_position' = 8,
            'supports' = array( 'title', 'editor', 'comments', 'thumbnail', 'custom-fields' ),
            'taxonomies' = array( '' ),
            'has_archive' = true
        )
    );
}

I'm using the roots starter theme. Is there some extra configuration I need to do to make custom post types work with it?

Thanks.
