    New paper

    Richard and the gang took care of my leaking roof by pulling back a section of tiles, replacing the paper, and expertly reassembling it all. They educated me, an avid DIYer, on known issues with my roof's construction style and what leads to the leaks I was having. Extremely kind and courteous, prompt service as well. Crew cleaned up after themselves (which involved roof-buried ash blown from nearby fires years ago). Highly recommend them to anyone.

    We used Rational for the re-roof of both our main house and our ADU this year and I have to say they are the most skilled, professional, and also nicest roofers I have ever worked with. They not only handled our roofing, but also helped replace the siding on our dormers that was found to be rotted during the demolition process. We also had them install all new insulation for us since the old insulation was incorrectly installed, insufficient in R-value and also not installed everywhere we needed it. They also replaced our skylights with brand new automatic ones as well, and they handled the whole process of dealing with the skylight manufacturer for us when one of the units we installed turned out to have a faulty control unit. Rich and Ryan and the whole crew are class-acts. They do the job right, and take care of the customer in the process. Thanks guys!

The roof looks great and I'm not worried about rain now. The quote was on the higher side but because of their professionalism I'm glad I went with them. I highly suggest them if you want a real good job and won't just do the minimum. Thank you Terrazas Roofing!

He emailed me a comprehensive estimate and offered me a financing option that was very affordable. Interest-free loan if paid in 18 months. I asked the main office lady (Sam) to please do the legwork and obtain the permits for me, and she did so effectively and got them right the first time. When the crew came out to replace my roof, their Foreman (Jose) explained each step to me as they progressed. The first day was tear-off and replacing 3 sheets of plywood. The second day, the crew met with the State Inspector who approved the crew to proceed to install the new shingles. Final Inspection was done by the same Inspector during the following week and Jose came out to meet with him and get the Final Signoff. The whole process was smooth and friendly which I believe is due to this family-owned roofing business who actually CARE about doing a fine job for a fair price. I can completely recommend them for your roof.

David came by to inspect my leak by physically going up on my roof. He told me that he would email me the estimate next week. I waited until yesterday, 4/7/26 to reach out to David for the estimate. I texted him at 9:23 AM about when he would be sending me the estimates for either the repair or the entire roof underlayment replacement. I saw that he read my text message but he did not reply back. The next day I texted him again that I will be informing his office of my interaction with him. He texted back right away that he is out of town for training and he apologized for the late response. I told him that I will not be using his company for my repair/replacement due to his lack of care and commitment. He texted me by the name of Trina and Angela, although all he had to do was scroll up on the text messages for my name. If it's this difficult to get a hold of this company to give them money for their service, it might be impossible to get a hold of them once they have your money.

When Arturo came out to inspect the roof, he provided a verbal quote, but no written estimate was ever sent. Since my husband and I were in the process of making decisions based on contractor bids, I later reached out and specifically asked if a written quote could be provided. After waiting without receiving anything, I followed up with Arturo by text and was told that he would send the quote later that day. Four days passed, and I still did not receive the written estimate or any update. I sent another follow-up message and received no response at all. The only positive part of my experience was communicating with their staff, Abigail. The person responding to my texts, who I believe was Abigail, was responsive and helpful whenever I reached out to the company's main number. Unfortunately, despite her responsiveness, I still had difficulty getting the information I needed from the technician assigned to my project. I understand that delays can happen, but timely communication and following through on commitments are important. Based on my experience, I was disappointed by the lack of responsiveness and would encourage the company to improve communication between their technicians and potential customers.

We started with an initial inspection and quote from Leo, who was very attentive, he took the time to explain the process clearly and addressed all of our questions. They even tarped our roof on very short notice just before the rains arrived. Special thanks go to Pablo our project foreman, Ethan, and the entire crew for their professionalism and doing such a beautiful, quality job. Pablo was very attentive, he listened to all our concerns and was always respectful and considerate of our needs. He took the time to explain the problem areas as we had a lot of damaged wood, took pictures for me and went through repair options, always being fair and honest. He clearly takes pride in his work and works hard to ensure the best results for his customers. They were always on time, cleaned up thoroughly after each workday and completed the project in 5 days. After the project was completed we had minor concerns in the following days and the team took care of these promptly. We highly recommend them you will not regret it.

I was provided with a non English speaking crew, which made it hard to communicate important details. Because of this, I was never informed that my previously installed EV charger would create a solar permit issue. That oversight ended up costing me an additional $2,000. For a company charging at the higher end, I expected clear communication and a thorough review of existing electrical work. Instead, I was left paying for issues that should have been identified upfront. My advice to future customers: - Make sure they thoroughly review all prior electrical work done in your home. - Ask specifically about permit implications before signing. - Get clear confirmation on who will be onsite and whether they can communicate effectively with you. - Do not assume they will proactively flag electrical conflicts, you may be asked to pay for corrections later. The company is on the expensive side, and I accepted that cost in exchange for what I believed would be a smooth, well-communicated experience. Unfortunately, the communication breakdown and unexpected added costs did not justify the premium pricing. Proceed carefully and ask very detailed questions before committing.

This was a huge project with our roof having 17 valleys which required extensive planning and precision installation. The total job cost was in the six-figures. We could not be happier with the outcome. Chris Barnett and Blake Cox were consummate professionals not only leading up to and throughout the job, but afterwards as well. We had some issues relating to the gutters, which were not related to the re-roof itself, but Chris and Blake wanted to make sure that everything worked perfectly and so paid us a visit a few more times after the job was complete and made absolutely sure that the roof channeled water in perfect coordination with the gutter system. I have worked with many roofers throughout my career in property management and Barnett Roofing is the absolute best of them. I found them via their outstanding reviews here and so thought I should complete the loop and make sure that others know what my experience has been. The only thing I wish is that they could handle my roofs in other regions but understandably, they are local to the greater Los Angeles area. Superb workmanship, quality and support - could not ask for more!

The entire crew worked seamlessly work together in unison to finish my whole reroofing in 3 days. I was initially skeptical since others stated 5+ days, but I could see how organized and efficient the team was. Since roofing is expensive and stressful, I made sure to get four other competitive quotes from other roofers. The price from ASR came out the best with the same specs, but I would still have went with ASR even if they were more expensive, just because of the trust I had in Bryan. Throughout, I got to meet Bryan's father, Frank who has 30 years of roofing experience and was accommodating to my needs such as when I requested protection of my garden during tear-off. I also met Bryans brother Steven during the shingle installation, which reinforced the sense that this was a family business that genuinely cares about the quality of their work. Finally, after the installation was finished, the team still cared very much about passing inspection for permitting and to ensure their reputation is upheld. Even after payment was completed, they continued providing follow-up support when needed, which gave me additional assurances in their commitment to quality. I highly recommend All Service Roofing (ASR).
