    New Roof!
    gina t.

    Marcello and his team were amazing, thorough, professional, responsive, courteous and efficient. Our roof was done in 5 hours! The team was respectful of our home. Marcello knows how to take care of his customers and close out the job. It's always hard to find trustworthy and honest contractors and I'm so glad we did. Price did not break the bank and was reasonable. We are beyond happy with our new roof! Thank you for an amazing service! -Gina and Eric

    I would highly recommend Diamond Roofing Systems - 5/5 stars! Alex Lopes was our project manager and we were very impressed with his professionalism, communication and progress updates from the initial estimate to project completion. The cost of the project was competitive and he was able to work within our budget. We had to do a complete re-roof for our flat roof and Alex was very knowledgable about the process; he pulled the permit with the city and managed the project in a timely manner. He went above and beyond with all of our requests, no matter how big or small and took progress photos/videos before/during/after. We appreciated his attention to detail to ensure the roof was completed in excellent condition. After speaking with so many other roofing companies for initial estimates, I am glad we decided to do business with Alex and Diamond Roofing Systems.

    Joao and his crew were very professional and efficient. I would reccomend them for all roofing needs. He went above and beyond in offering recommendations and was honest if they were necessary. Some companies will tell you what you need without explaining the benefits and costs. Thanks again!

    Our roof was about 30 years old and it was time to redo it and the gutters. Everything about working with Diamond Ridge was great! We got 4 offers before deciding. We loved Sam our project manager and everyone else we touched base with along the way. Very quickly, we have our beautiful high quality new roof and gutters with long warranties. Of the 4 estimates, 1 was a higher but the others were in the same ballpark for 50 year materials.

    This is my second review for Diamond Ridge Roofing, my first review was based on my quote/estimate experience. Our roof was so outdated and it needed a full replacement before we hit the rain season. After interviewed with more than 12 different roofing companies, we finally decided to go with Diamond Ridge Roofing for our roof replacement project. Andre Moura (Our project manager) was able to start the job as soon as we got the permit within a week, originally I was told the job would take up about 4-5 days but it ended up they were able to finish everything in just 2.5 days, the longest time was waiting for the inspector to finalize the work. Andre would send pictures and videos to provide the updates in a daily basis. We love the drone videos and pictures and it shows us in a very professional way. Diamond Ridge has exceeded my expectation, not only just because of the exceptional customer service we received from Andre Moura, his roofing team, the owner Jose and also Fred from QA, the person who assist to get our permit was able to get it done quickly. The quality of work and materials, efficiency, warranty, thorough explanation of each steps and transparent progress are what we were looking for, not to mention the financing options. Like everyone said this is one of the biggest investment for your home, and you would want to choose the right company to do so. Andre and his team were able to provide and deliver the professional services we were looking for. I highly recommend Diamond Ridge Roofing to anyone who needs any roofing services. Thank you so much again Andre and the owner Jose. We really appreciated your help with this project. Thank you.

I got the estimate that night and it was very reasonable . (They will match other estimates). I couldn't be happier with the work Tony and his helper did, even did more than was on the written contract and didn't charge extra. He said my roof should last another five years. Definitely plan on hiring them when the time comes for a new roof.

He's conscientious, reliable and honest -- so rare in today's environment unfortunately. I felt completely taken care of throughout the entire project from quote to continued maintenance. He documents every step of the process with great photos and videos of the before, demolition, partial installation, and complete finished product so you understand every detail. He arranged to visit my house during the first rain of the season after my re-roofing to make sure everything worked as intended, and has consistently made himself available whenever I had questions. He has such pride of ownership for his company and it truly shows with how he treats his clients. While I don't look forward to future roofing issues, if there are any I know I'll be an incredibly capable hands if/when the time comes with Tony. I did a lot of research and received a lot of bids for this work and California roof technicians had a competitive price and Tony's bedside manor made me trust him from the beginning. I didn't feel like I was being sold, I felt like I was being shepherded through a complex process by an expert. Rarely in life do you find something that is GREAT QUALITY, FAST (completed in under a week) and HIGH VALUE. Not only this, he was able to schedule the work on a tighter timeline as I was expecting my first child and wanted to work completed before I got close to my due date. Bottom line, I could not recommend Tony more. If you need your roof done, he's the guy.

We had to reach out ourselves to find out what happened. In response, they blamed one of their employees for leaving and had no idea about the project despite the whole team cc'd on every communication since the quote. Geovanny in particular demonstrated a complete lack of accountability and professionalism. He was curt and disinterested in his responses, offered no apology, and showed no consideration for the time and effort wasted on our end. When we asked for reassurance on the revised timeline and quote Geovanny simply told us that it was "not up for negotiation." It is doubtful that Q7 is interested in or values your business. With service this bad before they started work or got paid it is hard to imagine they would even pretend that you exist afterwards if an issue were to arise. EDIT: See business owner response below obfuscating rather than simply offering an apology and solution to ghosting the project without a single attempt to reach out about it. Evidence that this was not a one time accident but just business as usual
