    The Challenge

    Project Overview

    RTS Roofs is a roofing company whose WordPress site suffered from outdated software, an old PHP version, and slow hosting. They needed a comprehensive overhaul including speed optimization, technical SEO, and hosting migration.

    The site was running on outdated PHP, outdated WordPress core, and slow shared hosting. Beyond speed, the site had technical SEO issues that were limiting local search visibility. A complete technical overhaul was required.
