Capstone Roofing replaced the roof on our duplex in Rincon Valley last week. Having previously had a bad experience from a different company we were nervous about this project. Turns out we worried for nothing. Capstone Roofing did an amazing job. The workers were fast, friendly, efficient, and clean!. As a matter of fact, the property may have been cleaner when they left than before they started!

They showed up exactly when they said they would and completed the job faster than we expected. One thing we really appreciated was the great communication with their office staff. They responded to every question in my multiple emails - always patient - always clear. We cannot say enough good things about this company. Thanks Captsone!

We were very impressed with Capstone's professionalism. We had our house and granny unit roofed in record time. They started promptly at 7:00 am and were done by 4:00. The work was efficient and well performed. We will recommend Capstone. Great company.

Where do I start, I am grateful that my husband and I choose this company. It took us while to decide on what company to use. When the day came, the crew members were prompt on arrival 7am. By 2:30pm, they were done and cleaning up. As a nice gesture, we provided lunches, drinks and ice on a hot day for them. To show our appreciation. Thanks for a job well done Capstone and Crew.

Having a roof replaced is a big ticket item so I was expecting quality material and workmanship! And that's exactly what I received from Capstone. One of the best experiences I had with any work on my house. Exceptional service from Bill who provided the estimate and answered numerous questions. On the scheduled roof replacement day a group of workers started removing my old roof at 8:30 and had the entire roof replaced and the job completely finished by 2:00 that afternoon. They were all very polite, worked clean and the noise wasn't all that bad either. I highly recommend them. Thank you Capstone for my beautiful new roof!

Incredible all the way around. Capstone was quick and efficient with the initial quote, came when they said that they would, and did a fantastic job. All done in one day. The crew was respectful and courteous as well. On top of everything, they sent a crew out a month before the job to tarp and cover a hole in the roof. HIGHLY RECOMMENDED.

When you're forming hangs out on the phone all day and watches all the other guys work it doesn't look so good. The guys do a good job and they get the job done quick. But where I come from the foremans lead the crew they just don't boss people around. I speak fluent Spanish and I heard the guys talking about how much better things were with Nathan was around. Whoever Nathan is sounds like things aren't doing so well since he hasn't been around. I strongly suggest hiring Foremans that are willing to work the guys and show leadership.

The owner of Capstone came out to give us a bid. He was professional and easy to talk to. Capstone's bid was in the cost range we expected. The communication with the office was professional and very pleasant. The workmanship was fast and efficient. The supervisor was readily available during the work being performed. The list of past roofing jobs in our area was readily made available. This gave us a look at the color of shingles we wanted. Our expectations were met. Fred

Highly recommend this roofing company. Submitted a request for a bid, within a couple of days Bill came out, he flew is drone over the house, walked around and he was done, then a few days later I received my bid. The bid was very competitive and everyone I dealt with was super friendly and professional. The day the 20 roofers arrived, all of them arrived before the 7am start time and were ready to go at 7am.

The supervisor (sorry I don't have his name) was amazing. He explained to me exactly what they would be doing and he and his team carried it out in unbelievable efficiency. Our house is pretty large and has an extremely steep pitch roof. They had all the equipment and supplies needed to carry out the entire job in 1.5 days. Then his team cleaned up every last sign of them being there and were on their way.

The team at Capstone Roofing just finished replacing our roof and I HIGHLY recommend them! Bill was my main point of contact and he was thorough in his appraisal of the project and helpful along the way when we added two skylights as part of the job. Pricing was competitive to other vendors and while I was skeptical of his estimate the massive amount of work would be completed in 1 day, it was finished in under a day. His prompt and courteous team of 18 moved quickly, rebuilt parts of the roof that had rotted and left the exterior area cleaner than they found it. 10/10!

I was so amazed at the whole process. From the quote through the execution this company was 5 star all the way. The communication was great. They arrived exactly when they said they would. Everyone was so polite. The work was finished in one day. They truly left my yard cleaner than they found it. And their price was less than most

From start to finish, 6 hours! I've never been so impressed with a business as I am with Capstone. They left my back patio and driveway cleaner than before they got to my house. They arrived right exactly when they said they would. The crew was as well choreographed as anything I've seen, you could tell they had the process nailed down tight. Just really impressed.

6 hours start to finish. The whole process with Capstone has been great. From the list of addresses, they give so you can check out the colors to the quality and speed of the work everything was great. When comparing make sure you do apples to apples as other bids with 30-year shingles and these guys do 50. They left our back patio and yard cleaner than it was when they arrived. Did I mention they were done and cleaned up in six hours.

I am absolutely delighted to write this review. My only wish is that there were 10 stars. I had an interaction with Bill (owner) today that 100% made my day. He was professional, kind, courteous and so so helpful. This company is the real deal and I am so happy to report that good people exist in the world and Bill and his team are in that group! If you are in doubt, look no further.this is the roofing company for you!

Incredible job from bid to scheduling to installation. I can't believe how efficient and professional EVERY member of the team working were. Our 3000 sq ft house was stripped/papered/repaired where necessary/installed - in less than eight hours. A person has to see it - to appreciate the organization and hard working individuals that made it happen.

We had a 3 1/2 inch storm the very next day and not a leak to be found. We can't be happier. We will have two roofs done in the near future and I will recommend Capstone, here in Santa Rosa to anyone needing a roof replacement.

Can't say enough other than, high quality work, on time, and fair pricing. There was not any debris left over after they re-roofed my house in one day. Amazing work! I liked the fact that the owner is Sonoma County native and love to support local businesses like his.

Capstone squeezed me into a tight schedule (I'm getting the house ready for sale), showed up on time on the date promised, and with enough workers to finish the job in one day! And my roof is definitely most difficult: a steep pitched A-Frame in front with a wider roof toward the back, all 3 stories in the air, with lots of stairs and uneven terrain surrounding the house!

No problem with these guys; it was actually exhilarating to watch people work so quickly, efficiently and carefully! The foreman on the job made sure I was consulted when necessary during the job because, as we are all expecting, problems were discovered when the old roof was removed. I initially thought that this would delay them finishing, but they still managed to complete the job and then actually leave the house and area around it cleaner than they found it!

The roof and gutters look great! When they finished, the foreman had me do a walk around to make sure I was happy with the job and clean up and that there were no problems. It's been years since I have had such a positive experience with any company, roofer or not! I give them the highest rating and recommendation possible!

From beginning to end of job, Capstone has impressed me. We received an estimate from them YEARS ago to have our roof replaced, when we bought our house. We were finally in a position to do so this summer. I called and they still had our records on file from 6 years ago! Nathan was out to look at our roof within just a few days, the estimate received within 2 days after that, and they came back to do the tear off and roof installation just a few weeks later. (BTW - the the other roofer I consulted couldn't come out for weeks to even give us an estimate, took a week to get the estimate back to us, their estimate was $10k more than Capstone, and they wouldn't be able to install said roof until Oct or Nov!) When the Capstone team arrived at 7am, there were many of them and they worked quickly and efficiently.

They were in communication with me throughout the project to let me know when they needed to do a bit of dry rot repair. I was shocked when they were finishing up by 12:30! They cleaned up so well that you would never know they were here in the first place. And the roof looks really wonderful! This was all around a great experience. I wouldn't hesitate to recommend Capstone 100%!
