    When it comes to picking a construction company it boils down to two questions really. What is the quality of their work? Are they fair and responsive to customers? Bay Valley earns five stars from us on both accounts for the job they completed at our house. Here is why... We accepted the bid from Mr. Raul Diaz because we appreciated his candid, transparent communication about costs. We had been warned that construction companies often execute multiple surprise change orders to increase their profits throughout a job, but this never happened with Bay Valley. The one increase in cost that was unexpected was understandable and due to observable issues with our electric system infrastructure. As Mr. Diaz had initially promised, we stayed on budget throughout the job. The quality of a company's work is the end result of many small choices. We were both present during the entire job. We watched each step of the way and saw that all of the lines were perfectly straight, and everything was made perfectly level at each step of the way. One of Bay Valley's greatest assets is a finisher who does meticulous work. He came in to put the finishing touches on the flooring, every single door, the molding around the doors, the aprons for the windows, and the finishes for the bathroom - all done perfectly. Bay Valley also worked with subcontractors who held similarly high standards - Baltodanos for texture and taping of drywall and S.Y. Electric were both top shelf companies that did excellent work. In the end everything was done beautifully. We are 100 percent satisfied with how everything turned out. Also, this is important, because living in a house throughout a major construction job is an inherently stressful process. Never once did we witness any argument between anybody on the crew or with any of the subcontractors. Everybody worked cooperatively together with capable leadership and helpful communication from John Piermattei. Mr. Piermattei was wonderful to work with throughout the process. He was fair minded and a great communicator. For example, he warned us that there would be a lot of dust and then put up several high-quality dust shields that prevented nearly any dust from getting into the rest of our house. I noticed that the entire crew was really professional in the small things as well. For example, the worksite was always kept clean and organized. They never left over a weekend without putting their tools in a corner of the room in a neat and organized way and sweeping out the room. Every job will have a setback or two - this we accept as inevitable. Like any other job, this happened during the process. Here's why I mention this - you cannot know how a given company will actually treat you until you have a setback. The way that Bay Valley handled these setbacks was evidence to me that this company is dedicated to being decent, fair and reasonable with its customers. They communicated clearly with us and resolved each of the two setbacks in a way that left us feeling respected and treated fairly. Our understanding is that Bay Valley is transitioning to becoming the Bay Area's Premier roofing company. They will now be working on installing solar panels that are part of roofing systems in affiliation with a high-quality product made by GAF. We feel very fortunate to have been able to work with them before they made this transition. They made a beautiful room extension for us. If future customers have roofing needs or want to install these kinds of solar systems, we highly recommend Bay Valley as a company that is run with integrity and very high standards. 5 stars from us!

    We just finished our home's expansion (a very complicated project) done by Bay Valley Contractor's back in July. This was a not that so easy project. Both Bay valley contractors management and their staff member did a great job with excellent result. First of all they treated our home as their own home and were cleaning after themselves every day they finished their work even we didn't lived there during the construction. They were on top of things the whole time during the planing , permitting and construction process. It was a pleasure working with Both Raul (owner) and John (Manager, Forman) the entire time. Looking forward to work with them on the next project and enjoying some return costumers discounts from them.

    We've hired Bay Valley contractors for a couple of roofs. We had good experience in the past however when we hired them for a roof replacement this April they did a sloppy job. - Ugly stucco patch. A couple of neighbors even came to tell me that "your roofer did a terrible job with your wall, are you going to repaint?" - When they took down the old gutter a bit of wall damage occurred. They should have painted the exposed stucco before adding the new gutter but they didn't. Now it's very hard for us to paint the stucco to avoid water damage without taking those gutters down! - They left a huge mess in our attic. I didn't know about it because they picked up in the yard. When my electrician told me that our attic is covered in roofing debris I couldn't even believe it. He said the roofer should have protected it with a tarp and it's unusual that it's left so dirty. I uploaded the photos my electrician took to show me, but it's actually worse than the photos can show. - They also left roof debri in the gutter, which can clog our new gutters - The estimator gave us a verbal estimate on lifting the solar panels (by a third party provider) but never provided us a written contract, until the day before the take down. They called and said the solar take down would be $6000 (in addition to the roof replacement charges) instead of the $3000 that we were told before. With this change we decided to evaluate other options including getting new solar panels. We wanted them to inform us the exact cost of the different sizes of the solar panels in order for us to decide, but they said "You just need to tell me that size of the panel you want. Our workers are ready to start the job and you have to decide now!" without even telling us how much it would cost. We were firm that we are not starting the job unless we know how much will have to pay, and finally an hour later we received the solar contract in the email. The solar part was done by a third party but the estimator of Bay Valley recommended the provider and was supposed to coordinate for us. It could have been much less stressful if he didn't wait until the last day to tell us about the big price change. Although the review on the company is overall negative, i would like to mention that the owner Raul had been extremely professional and courteous as usual. Maybe it's just hard to maintain the quality of the crew with the expansion of business.

We had 4 different roofers come by to give me quotes and estimates for repairs, but we eventually went with Apollo Roofing. Shahar, their sales rep, provided me with a very detailed analysis of what needed to be fixed and even provided me with multiple quotes. He even showed me drone footage of my roof and pointed out all the problem areas of my almost 40 year old roof. During the whole process, he was very accommodating and provided updates along the way. While the project start was postponed due to weather, it was worth the wait as they did a great job with redoing the underlayment of my entire roof in a timely manner. I would highly recommend them for any future projects and to my friends and family as they were very competitive in pricing compared to others while maintaining quality work.

Now that our roofing project is officially wrapped up, I want to give a huge shout-out to the team at Apollo Roofing. The overall experience was great, and the professionalism from both the crew and management really stood out. A special, well-deserved shout-out goes to our project manager, Andrew. His dedication to problem-solving, combined with his patience and compassion, made a world of difference. Andrew stuck with the project from start to finish, always providing prompt responses. What I appreciated most was how well he listens to feedback; he seamlessly pivoted his communication approach to bridge the gap between the roofers and us as homeowners, truly building trust along the way. We did hit a minor hiccup with inspection scheduling that caused some delays and issues, but management stepped up right away. Nadav quickly jumped in to resolve the problem, proving himself to be incredibly responsive, reasonable, and trustworthy. Despite that, the exceptional service, communication, and leadership from Andrew and Nadav made this a fantastic experience. Highly recommend them!

(As well as we wanting to adhere to the true aesthetic style of clean lines and edge profiles) We received 5 quotes and chose Equinox Roofing and we are glad we did. They were not necessarily the cheapest, but the price was competitive, they had a well outlined proposal, great reviews, and there were not any big surprises throughout the process that were not in line with what was outlined in the proposal. Ben, Abel (as the PM) and the entire crew were professional, responsive and worked rapidly to replace the roof in-between rainstorms that surprisingly popped up unannounced on the forecast. They resculpted previously problematic drainage areas through thoughtful insulation techniques that led to improved drainage flow and removed ponding issues that were there with the previous old roof. They also did a great job cleaning up at the end of each day. My wife and I are in the design industry, so we can be overly picky and there were a few tweaks we asked them to do throughout the process - which they did without any hesitation. You can tell they care about their craftmanship. Highly recommend Ben and the Equinox Roofing team.

I could not be more satisfied and we have a couple of projects coming up in the next year and will definitely use them. We now have a roofer for any needs. My highest recommendations for Ben and Equinox!
