"Peter came and gave us a very transparent and comprehensive assessment of the roof. Very professional and informative about all the work that needs to be done on the roof. He was prompt and left us a bid before leaving. You can't go wrong by calling Clear View roofing. "

"The exterior of our home had been neglected for years and it was starting to show. The siding was worn out, trim boards were rough, and the paint had definitely faded. Julian with Imperia Roofing & Exteriors helped us plan a full refresh with James Hardie siding and new paint. They also repaired a few window trim sections while everything was open. The whole property feels cleaner and more updated now."

"Excellent service, very fast, very professional!"

"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 would strongly caution anyone considering this roofing company. We had our roof redone in July 2025, and by February we experienced water damage inside our home. After inspection, the issue appeared to be related to poorly installed flashing around a vent. Instead of taking accountability or even seriously investigating the workmanship, the company quickly dismissed the problem and claimed it was caused by an animal, therefore not covered under their warranty. This was disappointing, especially given how soon the issue occurred after a full roof replacement. A reputable company should stand behind their work and be willing to thoroughly assess potential installation issues rather than deflect responsibility. The lack of accountability and unwillingness to help resolve the damage left us dealing with repairs on our own. Based on our experience, I would recommend looking elsewhere if you want a company that stands by the quality of their work and provides reliable customer service."

"Just started the project today."

"Great experience from start to finish. Professional, honest, and high-quality work. The crew was on time, efficient, and left everything clean. The roof looks fantastic and I’d absolutely recommend them to anyone needing roofing work."

"Joao was professional, honest, a great communicator and got the job done sooner than expected. Would definitely work with him again!"

"BEWARE !! This company is a SCAM. After signing a contract and paying $610 downpayment for getting windows installed, I also signed a three day cancellation policy which made me think i had three days to cancel. Contractor ( Daniel Khachaturyan ) did a really good job by having me sign that right away without saying that there were some exceptions in the back in SMALL letters. I decided to cancel on second day and after a week of not hearing from company or contractor , i decided to call the company to get my money back. To my surprise, the agent mentioned that they couldn?t reimburse me because ?NUMBER 17 IN THE BACK OF THE CONTRACT STATES DOWNPAYMENT IS NON-REIMBURSABLE? The agent gave me two options. I either lose the money or i can use that money for future projects with them. I decided to lose the money as i no longer wish to do any kind of business with this company. This is just to help others to be aware of this company and how overpriced their services are ($9k for 6 windows"

"They did a beautiful job, and did a great clean up! Looks so nice."
