My wife and I recently worked with Diamond Ridge to replace our roof, with Marcelo as our project…read moremanager. We've worked with countless contractors on many home projects over the years (HVAC, water heater, exterior painting, etc) and our experience working with this company was about as close to perfect as we've ever had. From the initial consultation to the execution and the final tying of loose ends, Marcelo always made us feel like he had our best interests in mind... like he's working on his own home. His bid was competitive with the other bids we got, but what really set him apart was his endless patience answering all our questions, his attention to detail even during that first visit, and his positive attitude. It's clear that he loves what he does, and it shows in the results. His team members all seemed very professional and efficient, and they worked together well as a cohesive and happy team. We loved all the in-progress photos and drone footage Marcelo would send us throughout the project. It went a long way toward making us feel at ease and engaged the whole time. Shortly after we thought we were done and concluded the final payment of the schedule, we noticed a few minor flaws. Marcelo still made sure every single one of our concerns were addressed, which we really appreciated. Obviously we don't expect to replace our roof again anytime soon, but we would definitely recommend him with no hesitation to anyone needing roof work. We really felt he went above and beyond to make sure we were satisfied with the work. Marcelo's a member of our team now. He's our roof specialist.

I cannot say enough great things about Diamond Ridge Roofing System and especially Marcelo Candido…read more After meeting with three other roofing companies, I was honestly stressed, each one tried to convince me that I needed to replace my entire roof over a leak caused by a single broken drain. One contractor even had me believing my roof could cave in at any moment. Then I met Marcelo, and everything changed. From the start, he was incredibly professional, transparent, and trustworthy. Instead of pushing unnecessary work, he clearly explained that he doesn't believe in persuading customers to pay for repairs they don't actually need. That alone immediately set him apart. He used a drone to thoroughly inspect and video my entire roof, walking me through exactly what he saw and pointing out the specific areas that needed repair. After hearing vague explanations from others, this level of clarity and honesty was refreshing. Not only was his approach honest, but his pricing was also very reasonable, actually less expensive than most of the other quotes I received. Marcelo personally came out and stayed on-site with his crew to ensure everything was done right and met my expectations. After the repair, they even used my water hose to test the work and make sure there were no more leaks coming into my home. That level of care and attention to detail meant everything to me. A week later, I had a follow-up question and texted Marcelo. Instead of just replying with a quick answer, he came by the very next day to personally address my concern. That kind of responsiveness and commitment is rare. Because of this experience, I hired him on the spot, and I have zero regrets. While I don't need a full roof replacement right now, when the time comes, I will absolutely go with Diamond Ridge Roofing System and will specifically request Marcelo as my Project Manager. If you're looking for honesty, quality work, fair pricing, and someone who truly stands behind what they do, Marcelo is your guy.

My gutters leaked in a few spots and I called Commercial Gutter for a repair or replacement quote…read more Carla answered and said to text a few pictures of the gutters to Paul, who would be doing the estimate, and then he would stop by for the quote. Paul came out about a week later, and determined that the gutters needed replacing on one side. He took measurements and it came out to about $1000 for 77 feet of aluminum gutter. The work was scheduled about two weeks later. Two guys came out around 7:30 in the morning for the old gutter removal and new gutter installation, and they finished up around 11. The gutters look great, and the style and color matched up perfectly with the other half of the gutters that did not needed replacing. The only issue was that when they removed the old gutter, in spots they dented in the aluminum underneath the gutter with their prying tool.

Review #1,056 Posted on 5.7.26…read more I've used Tri-City Roofing a bunch of times now as a property manager. Most recently at a house in Union City I manage just this last month in April to do roof repairs & a new gutters throughout. Tri-City is a family owned company that's been around for years. They're extremely organized and have really transparent & good communication skills. Their work is clean, and they do a good job for a very fair price. Vendor reliability is tough for consumers or someone in my position professionally as well, you have lots of people counting on you to get quality work done, at a fair price. I've had great experiences working with the team at Tri-City Roofing.

Tri-City Roofing has been an AMAZING find for our roofing needs. We found out suddenly that our…read moreroof shingles may be failing so Tri-City was our first call. Greg came out very quickly for the initial inspection. He was courteous, honest, and helpful. They gave us their assessment within a few hours of their inspection. We needed a whole new roof. We were in shock but Tri-City helped us understand all of the different aspects of why. We emailed many, many questions. We always got very prompt, detailed responses (sometimes within the hour of sending the email!). When we got the bid, it was very competitive to the other bids we had received. Tri-City's bid though had many more options as well as a breakdown of ALL of the costs. When we signed our contract with them, we felt that there would NOT be any "gotchas" during the project where the contractor would say, "Oh we have to charge you more than we thought". Tri-City gave us the option to go to the roofing supply company, QXO/Al's Roofing Supply, to select which roof we preferred. Jeff at QXO was very helpful and reinforced what a good company Tri-City was to work with. When asked about scheduling, again, Tri-City & their office staff Jeannine and Viviana were super helpful. They were able to get us on their schedule quickly to work around things from our schedule. Once they started working, the foreman Oscar was easy to access and again, very responsive and helpful with our many questions. There were various crews that came at different stages of the total roof replacement. Each of the workers wore Tri-City Roofing shirts, acted professionally and courteously and worked hard the entire time they were here. We were told the project would take @ 3 days to complete. They were completely DONE in TWO days!!!! We were able to take photos and observe the different stages of their stellar work. At the end of each day, the workers made sure the house, garage, & grounds were clean and free of debris. They were very careful about the pets we have as well. When we started this project we were worried and overwhelmed. Once we met Tri-City Roofing and got to know them through our many, many questions via emails and phone calls, we knew that we were in good hands. Tri-City Roofing has the experience you want in fixing or replacing your roof. They have the right crews, staff, and knowledge to help with anything you need regarding your roof. They are competitively priced and is willing to give you options so you can pick what works best for your wallet as well as for the beauty of your home. Our new roof is spectacular! We are confident that this new roof will last us for many years to come. We also know that if we have any concerns regarding our roof, Tri-City Roofing will be there to help and support us. They are in it for the long haul which we very much appreciate. On a scale from 1 to 10, they are a 20+!! Thank you Tri-City Roofing!

Right from the start, their thoroughness blew me away. When they first came out, they flew a drone to take photos and videos of the roof, and then used that footage to explain every single issue to me. I have never had a company--regardless of the project--explain things in such clear, impressive detail. Throughout the entire process, they were incredibly responsive and went above and beyond. They answered every single question I had with absolute honesty and provided practical suggestions that made sense for my home. Their communication was flawless--they were available whenever I contacted them. What really stood out to me was the personal care. The owner even got on a call with me to address a few specific concerns I had about their products. They are not the cheapest option out there, but you absolutely get what you pay for. The quality of work, advanced technology, and peace of mind were worth every penny. I am incredibly happy I went with them!
