The first three are Google’s own figures for Sierra Roof, read on 24 September 2026; the share is of every rating Google has counted, not of the review texts on this page. The median is ours — the middle figure among the California roofers we list with enough ratings to compare.

Much higher than most — the typical roofer in California sits at 0.8%. A higher share is a reason to read the critical reviews below, not a verdict.

Communication was very poor. Job is not complete. Almost every day a crew was a no-show from day one until they finish two weeks late. I was pressured to sign off on progress and completion before stucco patching, gutters or inspection. My credit card was run for final payment days prior to work completing. I was also promised a 50 year warranty and delivered a 5 year workmanship warranty. Salesman told me based on his assessment going on the roof that I would need 5 tiles and then after paying the desposit was told I needed 180!

the job was done good, but they will offer me a 1K discount just to sign the contract but at the end the job they denied me the discount because they use extra materials that they never clarify

Once you hire them, they spam your phone several times a day for years to get more work.

If I could give you no stars, I would. You sent competing salesmen to my house...one from each of your companies to compete against each other for my business. You tried to trick my husband into signing off on an additional $8k of wood we …

I arranged for a roofing inspection and estimate, but since the homeowner wasn’t available, the inspector set up a follow-up appointment for the following Monday at 9 AM. After waiting until 9:20, I called to check on their arrival. …

Hi Josue, thank you for taking the time to share your experience. We’re truly sorry for the frustration and confusion you encountered, as this is not the level of service we aim to provide. It appears there was a breakdown in communication regarding the scheduled appointment time, and we understand how disruptive that can be, especially when you had made arrangements around a specific time. We apologize for the inconvenience and for how that interaction felt to you. Regarding the follow-up call, we regret that our outreach came across as accusatory. That was never our intention. When company equipment is reported missing, our team is required to make inquiries to determine its whereabouts, but we are sorry that this process made you feel uncomfortable or blamed in any way. We appreciate you bringing these concerns to our attention, as they help us improve our internal communication and procedures. If you’re open to it, we would welcome the opportunity to discuss this further offline and better understand what happened. Please feel free to contact our office directly and ask for management. Again, we apologize for your experience and wish you all the best moving forward. - the Sierra Roof team

Avoid this company! They gave me an estimate that was significantly lower than other quotes, but then tried to charge me double the original price once the work started. They also took weeks longer than they promised to finish the job, …

Got my roof repaired with Sierra, they were the only ones who didn't try to sell us a full roof replacement being that our roof is only 4 years old and the company that installed our roof went out of business. Thank you Lisa

We recently had our roof replaced by Sierra Roof and overall had a really great experience. The whole process was much easier than I expected. Everyone was friendly, they kept us updated on what was going on, and the crew worked hard and cleaned up everything when they were done. Our new roof looks great and we’re really happy with how everything turned out. I would definitely recommend Sierra Roof to anyone looking to get their roof done.

Excellent service
- 3 out of 5Jennifer Phallera month ago
The best parts of working with this company for the first time were connecting with Nathan, Andres, Aldo, and Diego and feeling confident that our roof turned out entirely better than its original state. Throughout our project, Nathan willingly answered our technical and general questions, listened to our needs and concerns, and problem-solved as issues came up. He is communicative, consistent, and considerate and we are fortunate to have worked with him. Although our interactions with Andres were limited due to his packed schedule, he made a good impression by being polite and assuring us that his team would deliver quality work. Aldo and Diego really stand out to us because they are very skilled in their craft and absolutely hard working. We are completely satisfied with their solid craftsmanship. However, despite things going smoothly with these people, there were definite challenges along the way that were not properly addressed, one of which is a major red flag. We reached out to the owner on LinkedIn on June 17th to connect with him, but we haven't gotten a response as of posting this review, which doesn't sit well with us.

Hi Jennifer, John has been trying to schedule a good day to come out to meet with you to address your concerns. Can you please call our offices so you can connect with him? He does not monitor his LinkedIn, the best way to contact him is to call our office. Apologies for the scheduling conflicts, but please call us as soon as possible so we can make it right. Thank you - the Sierra Roof team

The company came in at the best price and it included the permit too. This topped it off along with a 10yr labor warranty and 30yr for the shingles. I am very pleased and would definately recommend them to anyone looking to get a new roof!
