    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!

    After meeting Ryan and the crew, I knew everything was going to be OK and that I wouldn't need to "oversee" the work.

They were punctual and patient with me as I missed our appointment time the first time. Irving was very kind and made another appointment for me. His crew came and didn't need much other than the door to the roof. They sent photos of what needed fixing with their quote and again of what they fixed with their invoice. 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!

    This is my first posting, but I felt obligated to warn others about my experience with this…read morecompany. Like they warn you about contractors, take the low estimate and double it. That's exactly what happened here. My estimate was around $23,000 but the final cost was over $45,000. They placed a lot of the cost as 'extra' but most of it became necessary. I chose this company based on their good reviews. But I think they prevented bad reviews. I would have gotten a 'discount' if I didn't write this review. The clause they added was: "As part of this agreement, both parties agree not to make, publish, or communicate any statements, whether written or oral, that could reasonably be construed as negative, defamatory, or disparaging toward the other party, including but not limited to statements made on review platforms, social media, or to third parties. This includes statements regarding the project, the services performed, or the resolution of this matter. This obligation applies indefinitely." It seemed pretty standard, so I guess I am not the first to get it. When they added over $6,000 to the estimate, I requested to be notified of any further changes. I heard nothing. But when I called to ask what was going on, I was told that the cost had increased to over $40,000. And I had to call to find out. When I asked to see the items I was being charged, I was told I should have gone up to roof and watched to verify what was actually being used. That response alone speaks volumes. My advice: be careful when you get an estimate from a company who doesn't have someone go on the roof. I thought using a drone was modern and efficient, but it can also be lazy and gives them no idea what needs to be done --adding costly surprises later.

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.

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.

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!

I would definitely recommend them.

Importantly, there is no subcontracting unlike some other roofing companies which stated their use in fine print. 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).
