"Pete (the owner) and his roofing crew (Genaro, Alberto, Pedro) were great! Pete replied promptly to my initial inquiry and came out right away to look at the roof. Following that, it took somewhat longer than I had hoped to get an initial bid and to actually start the job, but his bid turned out to be lower than the others, and I could see that the delay was for the right reason -- Pete always prioritizes the roof he's already working on to make sure it's done well and as quickly as possible, so a house doesn't stay unprotected for longer than necessary. Once they finally finished earlier projects and started working on our roof, they were 100% on task from start to finish. They are a small company and ours was a complex, 4000+ square foot roof that required ordering special materials along the way, so it took about a month to complete the job with 3 guys working 40 hours per week. However, I really appreciated the way they always started promptly on time each day and worked closely with my wife and I throughout the entire process to make sure work was being done exactly as we (and the City's historic rules) needed it done. Pete and his crew were friendly and very accommodating of special requests related to the historic peculiarities of our house, skylights, neighbor's concerns about parking, etc. Many parts of the roof required creative, on-the-fly problem solving, due to the non-standard construction of our 1800's house. Genaro, especially, was great at innovative problem solving and did beautiful work, but everyone on the team was super dedicated, hard working, and skilled. We have already had one heavy downpour since the new roof went on, and not a single drop got through! I can confidently recommend Positive Results Roofing if you are looking for a small, personable company that is licensed and bonded and does quality roof replacements or repairs for a reasonable price."

"I was looking for a company to replace my roof and received several bids, but none of them made me feel confident or comfortable until Diamond Ridge showed up at my home. From the moment they arrived, I felt I could trust them. I truly loved their service and highly recommend them to anyone in need of roofing work. Definitely worth more than 5 stars!"

"I highly recommend DS Roofing! I needed a new roof for my detached garage. The old roof had multiple layers of old roofing and was in poor condition. DS Roofing came out and gave me a fair price for the job. The owner was very helpful and informative, answering all my questions. Once I selected the bid, the crew showed up within a few days and tore off the old roof and installed the new one very quickly. What impressed me the most was how clean the ground was after all the debris that fell during the removal process. "

"GREAT! Really appreciated this company! Another reviewer on Yelp recently spoke to the honesty of this company. I can vouch for the same. Felipe came out today (after we called yesterday, for an estimate), after we discovered them on Angi's list. He spent nearly an hour looking at our upper and lower roof, as we had discovered a water spot on our ground level ceiling. He was very thorough and looked in every place that he thought the roof might possibly admit water, but could not find places where the runoff (from chimney/walls of house) might admit a large enough amount of water that would cause the damage that we were seeing. Instead, he deduced that the evidence seems to be of a plumbing, not roofing issue. He thoroughly checked our roof exterior and told us that he felt the shingles/flashing/nails seemed in good shape for now, and though this type of roof should need replacement soon, he felt it would hold up another 2-3 years. He did not charge us for the estimate, did not try to sell us products we did not need, and could've easily found reason for us to spend money with a roofing company, as another has told us they thought the spotting was a "roof" problem, but I definitely feel confident that their professional opinion reflects honest dealings and when it IS time for us to replace the roof in a couple of years, we will definitely look to this company to work with!"

"Tesla came by and said that I need a new roof before they can install the solar. Jacob was referred to me and came by the next day and helped me a lot to understand the roofing system to install leak barrier under roof to seal the screws drilled in"
