Customers describe Diamond Ridge as professional, transparent, and trustworthy. One customer noted the team did a great job at a competitive price and would use them again. After meeting with other roofing companies, another customer was stressed because each tried to convince them to replace the entire roof over a leak caused by a single broken drain. Diamond Ridge explained that they do not believe in persuading customers to pay for repairs they do not need. They used a drone to inspect and video the entire roof, walking through exactly what needed repair. Pricing was reasonable and less expensive than other quotes. The team stayed on-site to ensure everything was done right and tested the work with a water hose. A follow-up question was addressed the next day in person.
Another customer praised the team for identifying the source of a leak in a bathroom ceiling, which turned out to be more complicated than originally thought. Communication was great, staff were friendly and skilled, and the project was completed in less than a week. A customer also shared that a competitive estimate was honored a year later, the roof was finished in three days, and the team went above and beyond by helping resolve old city permits. Another customer appreciated the extra miles taken to repair a leak and fix a tile roof, getting the roof squared away for the rainy season. Diamond Ridge is recommended for honesty, quality work, fair pricing, and responsiveness.
