"Clearview did a great job on my roof at the project done within a week very replaced"

"Replacing a roof is a big job. my roof was part TPO and part asphalt shingle. I like the honesty and integrity of this company. Also the quality of the materials and installation. I feel confident that my roof was done right."

"Our roof had been on the house for decades and it was finally time to replace it. Sean from Imperia Roofing inspected everything and walked us through the process. The crew worked efficiently and finished the project right on schedule. The new roof looks great and the whole process was easy."

"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."

"Diamond Ridge did a spectacular job! They took off my severely damaged synthetic slate roof, repaired all of the rotting plywood, added another layer of plywood on top (I wanted to stiffen my roof because we live less than a mile from a major fault line), removed and reinstalled my 33 solar panels, and were the lowest of four bids. They were incredibly easy to deal with and super responsive to my concerns. They even covered my pool with plastic to keep any demolition of the slate roof from falling into the water. I can't say enough about the quality of their work!"

"Professional quality from first phone call to install. We felt very comfortable and confident in our project being in the right hands. Finished earlier than expected and left us with a beautiful roof we can appreciate for many years. Replaced 2 broken skylights, torched asphalt for the flat area, and new shingles. He let us know every aspect that needed to be done and offered an extra service of coating his work for added protection. He let us know it was not necessary but let us know all options. The added protection was a step above and beyond. Very valuable inciteful company that gave us options to work with our budget. Thank you guys "

"Ken Armstrong gave a prompt response and appointment made. Thorough inspection advising that the 18 year old composite shingle roof was in good shape, but quoted anyway. Will definitely contact the supplier again in case of roof questions or service."

"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!"

"Tony the project manager did an excellent job we are very happy and satisfied. We did a full roof replacement. From start to finish, the entire process was smooth, professional, and stress-free."
