Diamond Certified Brings Contractor Rating System to Colorado

The expansion focuses on local roofers capable of meeting the company's 12-step rating standard, which evaluates businesses on quality and customer expertise. Companies interested in securing a "Founder" position—which includes five years of top placement and rate protection—must submit applications by September 23. CEO Greg Louie emphasized that the region’s susceptibility to hail and storm damage makes reliable contractor vetting a necessity for residents.

Unlike standard review platforms that allow open-access posting, the Diamond Certified process relies on surveys of randomly sampled, verified customers. Beyond customer feedback, candidates undergo credential checks covering business licensing and insurance, alongside assessments of their performance history. According to Director of Ratings David Pak, the goal is to help businesses compete on service quality rather than price alone, increasing their visibility in search engine results and local market comparisons. For the past 25 years, the organization has operated primarily in California, maintaining a directory that serves over 180,000 preferred members.
