Bay 101 Roofing is an phenomenal company. It was a pleasure to work with Jose, Isis, Mauricio, Teresa, Cesar, Jose P., Edgar and Carlos. They all were professional, knowledgeable, organized, patient, helpful, and neat. The step by step process for the shake roof and flat roof replacement was explained in detail and executed in a timely manner. The strategic preparation of the refooing project was focused on communication, transparency, efficiency, customer service and satisfaction. It was a reasonable price for all the work done. Multiple inspections with photos, videos and even a drone! Before the project started rain was in the forecast and they kindly came and placed a tarp over the flat roof. I really appreciated that gesture, so no more damage would occur. Bay 101 is exceptional! The shake roof and flat roof were removed with ease. The roof installation involved care and safety first. I was impressed with all their protocols. The gutters were also repaired, new attic venting, ... I highly recommend the conscientious experts at Bay 101 Roofing. read more

We hired Bay 101 Roofing to put a new roof and gutters on my wife's mom's house. They did an excellent job. The work was completed in a timely manner. They were professional and highly skilled. We got 5 bids for the job. Their price for the job was very reasonable and competitive. We had a tremendous experience with Cesar and his crew. read more

We hired Bay 101 Roofing ~10 years ago to re-roof the flat part of our roof (around 1,250 sqft), installing frame to slope the roof, insulation and torch-down material. The roof held Ok for 8 years, but leaked in the south and east corners of our home 2 years ago. Bay 101 made repairs under warranty. It leaked again last year -- and again was repaired. This summer I checked roof condition and found that it now came apart at the west side (photos 1, 2). On top of that, there were bubbles in the middle of the roof. Bay-101 told me that the reason for continued issues is that the material they used poor quality material and switched suppliers. However, the roof is no longer under warranty and I have to pay to replace it. We had to re-roof again! I hired another company to do the job and during the tear-down they found that while framing and insulation was done well, the torch-down material was installed on top of insulation (fire hazard) and also wasn't fully treated (as seen on photos 3, 4 and 5). The new installers told me that another layer of material (i.e. plywood) on top of insulation was needed to ensure torch-down material would hole. This cost me another $3,500 on top of the cost of re-roofing to get the insulation covered. I am not happy with the poor work done on my house by Bay 101 Roofing, to put it mildly! read more

Great service and job well done for my roofing. I worked with Cesar who was attentive, caring and communicative. My only bit I was over promised on completion time. My project was to be 2-3 days and expanded to 5 days. I still give this company huge credit for making my gutters and roof look great. Cesar took many photos and thoroughly described all the existing damages and had me climb to the roof to get a view. I felt that I could make the best decision and also comfortable to work with him. He also worked with my insurance company to gather information and to be a point of contact. I would certainly recommend this company. read more

Amazing. Got a referral to them from our realtor. The sales rep was always available, gave a detailed quote with reasonable pricing for various options, and most importantly had the job done in record speed. About that: I paid a deposit to secure my spot on their schedule in three weeks or so. But then they called me and said that due to a cancellation they had an opening earlier - which was the next morning at 8am. They finished the entire job, with permits and passing inspection, before my initial deposit check even cleared! This is probably a personal record for speed on a big job. read more

You pay for what you get. I went with Bay 101 because they had the lowest bid. What a mistake that was. They use low quality part from nails that already started to rust because they are not galvanized nails and cheap thin drip edges. Also on the bid they will try to sell you unnecessary upgrade that you dont need on your roof. The worker do poor quality job too. read more

BAY 101 ROOFING INC. has tended to my leaky roof problem with swift, and adequate service. I will not hesitate to call on them whenever I have issues with my roof. Their pricing is fair, and their service is trustworthy. read more

We received several quotes and decided to work with Bay 101. Their price was very competitive. Mauricio is awesome . He came to our house not once but four times to show us samples and explained the process. My husband was very detailed oriented and had a lot of questions . Mauricio was so patience and professional to answer all the questions. During re-roofing, he also came over to make sure everything was smooth and meet our expectation. When he found something were not right, he would help us to fix them. His crew also arrived on time everyday to work on the roof. They cleaned up the area and also made sure no messy on our neighbor's properties. It is a family run business and they care about their customers. The most important thing is Mauricio always responded to my text and they did a great job. I highly recommend Bay 101 and work with Mauricio. Let him put a smile on your face. read more

Working with Bay 101 Roofing is one of the best experiences I had with contractors. Mauricio was extremely helpful and patient to answer all my questions and concerns. He and his crew finished the jobs very fast and professionally. They cleaned up everything after finishing the job, and all my neighbors were amazed by work and the new roof. Before I contacted Bay 101 Roofing, I also received other bids, and Bay 101 was the most reasonable one. In the bid, Mauricio listed out all the items and materials to be used, and even recommended us good shingles which met our needs and not costed us too much. He even came to my house multiple times before beginning of the project, and went on top of the roof to make sure there was no extra layer to remove, so that no surprise during demo. During the project, Mauricio and his crew not only finish the re-roofing fast and well, they also help me fix some leakage in the gutter and put on some extension for the downspouts. They even used the extra material and shingles to replace the roof on an attached shad, which was not part of the project scope but they did it for free. I was really amazed. The inspection was smooth, and they reacted quickly when something was up. The paper work for the inspection was handed over after the inspection and I was really happy that the whole project was finished in 6 days! I would definitely recommend Bay 101 Roofing to anyone who is looking for a high-quality, professional and budget-friendly roof replacement. read more

Had our roof installed in 2015 by Bay 101 Roofing. Good experience overall. 9 years later, had a small leak in the garage. Happy to discover Bay 101 is still in business, called them - they had an after-hours answering service which was reassuring. Since it was a small leak, I told them it wasn't an emergency. They sent Mauricio and Jose out to take a look. Turns out one of the rat-proofing repairs someone did for me in recent years on the roof was sticking out, obstructing a water channel, causing water to pool and eventually seep under the shingles. Mauricio and Jose quickly diagnosed the problem and fixed it, and did some preventative work to make it much less likely to happen in the future. Overall great experience, prompt, professional service with a smile. Thank you so much Mauricio and Jose! Very glad we believed all the other Yelp reviews back in 2015 and went with Bay 101 Roofing. I hadn't been up on the roof since 2015, and the work still looks really good in 2024. Put that together with great customer service and you have a great roofing company =) Highly recommend! read more

I reached out to Mauricio, and he quickly came and gave me a competitive quote for my roof replacement for both main unit and ADU with flat roof. He explained all the details of the process and my responsibility and their responsibilities. His team was able to start timely and get the job done in 3 days. The quality of job and their friendly and honest approach was the game changer for me. They even cleaned up all floors of the house after installation of two sun tunnels. It is a family run business and they are doing overall great job. I strongly recommend them. read more

Cesar with Bay 101 Roofing was courteous, professional and hands-on during the entire project. Cesar and his dad (Jose) went above and beyond to make sure that we were happy with our new roof (including flashings, chimney saddle and skylight). I am very happy and glad that I chose Bay 101 Roofing. I have already recommended my sister and neighbor:-) Also, the pricing is very reasonable. Thank you to the crew/staff for an excellent job well done!!! JanetD. read more

What an amazing job this company did for us! The crews were professional and careful. They arrived on time and got the job done efficiently and well. Even our inspector praised their excellent work. We vetted three companies and would absolutely recommend them for the price and the great roof job. read more

We had our main house unit roof done by Bay101 Roofing team over 10 years ago, and the result was great! so we hired them for our inlaw unit again last year. Recently bay area weather was so bad that one of the gutter chips fell, so we called the team and Mauricio(not sure if I spelled the name correctly) came to our house the next day and fixed everything within 2 days. What a great team! read more

Highly recommend this company. Had a complete reroof performed. Mauricio was very informative and easy to contact for any questions. He assured me that if any problems arise with the roof to let him know and he would address them. Crew kept the job site neat and clean. read more

Full disclosure: Bay 101 asked me to leave this review, which I'm happy to do. I reached out to Bay 101 Roofing to get a quote on repairing some lifted shingles for a property I manage - they gave me a call and set someone up to come by within the next hour. Imagine my surprise when I heard back from them a couple hours later that they'd gone ahead and put shingles back in place free of charge! As such I can't speak to anything other than that they went above and beyond in customer service, and I'd definitely put them top of the list to consider if I have future roofing needs. read more

I am very happy on the work they done. Very professional and very nice people. Job get done on time. I would recommend to all my friends family. read more

Bay 101 just finished our roof replacement (single family home), putting in a new CertainTeed Presidential TL Solaris roof and removing our old shake roof that was nearing the end of its lifespan. Breaking it down into a few areas: Estimate/Communication: Overall really responsive with emails and phone calls and was able to come out and give an estimate pretty quickly. Went the extra mile to come to our home to show us colors, show us gutter samples, and pick up the check etc over several occasions which was helpful too. Worked primarily with Lorena in the office and then Jose about the actual roofing. Had some minor miscommnication initially about the scope of the work (thinking it was just for the garage vs entire roof replacement) but sorted that out pretty quickly. Jose also had me go up with him on the roof and showed me the completed work. Quality of work: I'm no roofer so take it all with a grain of salt- the completed work looks great and have had some rain with no issues. That isn't saying that much quite honestly but after doing some research, Bay 101 are also CertainTeed Select Shingle Masters as well as Owens Corning Platinum Preferred contractors meaning they can offer the best warranties (I'm not sure if you can just pay to get these things but I'd assume they have some quality standards that have to be achieved before getting this status). Hence, we ended up getting the best Certainteed Sure Start Plus warranty with 50 year coverage so that gives some peace of mind. They also were careful to clean up (which was appreciated given 2 young kids who might step on any stray nails etc) and were polite/courteous when they were over. Value: This is where Bay101 really shined, coming in not at the lowest, but the lowest (by several K) for roofers with well established reputations/select shingle masters/oc platinum preferred etc. Also, the final cost was very much in line with the estimate. Bottom line: Easy to work with, communicative, great reputation (via yelp, certainteed select shingle master/oc platinum preferred contractor etc), good value. Would recommend them to others looking to get roofing work done. read more

We requested several bids for our re-roof project during a very busy time - I'm glad we found Bay 101. Jose came out within a few days to take measurements of our roof and dropped off the longest set of references and brochures that we got. Some companies couldn't even come out for a site visit for a month. We requested an itemized quote for a full single layer re-roof along with new gutters, downspouts, and gutter guards. We worked with Mauricio to refine the bid with these options and a GAF HDZ shingle for better efficiency - he was easy to get in touch with by email and phone. Not only did Bay 101 have one of the most reasonably priced bids, but they also had their own experienced in-house crews and got to our job very quickly despite the tremendous rainy season we had this spring. We also needed to call for a couple of small issues after a few weeks and they sent someone out right away to correct them. I'd definitely recommend getting in touch with them for any roofing project. read more

I met with Maurico from Bay 101 Roofing for an estimate to re-do a TPO roof that has gone bad after only having it for 2 yrs. The company who did the TPO roofing denied the leak was their fault and would not pay for the damages or do the repair. Maurico was punctual, professional, and well informed about the different types of roof. He explained what the problems were with TPO roof, but more importantly, he helped find the possible cause of the leaks. There were obvious holes that I'm surprised the TPO roofers who did the job, did not see or just did not want to admit was there when they came by a few days ago to check the roof; they claimed they found no problems and that it was my fault for not keeping the roof cleaned. Also, I'm really afraid of heights but Maurico showed me safety techniques on how to go up and down the ladder and I was amazed at how comfortable I was getting up to the 3 story roof and down. I also appreciated that Maurico was professional when speaking about other roofing companies, he didn't bash any other companies (I never mention the company who did the work). Maurico spent a good amount of time educating me, he was very patient in his explanations and really did a thorough check of the roof's integrity; he also provided recommendations going forward and even offered to review my contract with the TPO company to see if I was covered by their warranty (now that was above and beyond any expectations I had). I would highly recommend Bay 101 Roofing company in a heart beat. Thanks Maurico for all your help today! I wish I had called Bay 101 Roofing 2 years ago when I got my roof done. read more

They confirmed an appointment with us but never showed up. When I follow up with them I can see they read the message but simply ignored it.

We hired Bay 101 Roofing to replace the tiles of our three buildings in our HOA. The tiles were about 30 yrs old but when our structures were initially built, the contractor may not have laid down the tiles with the appropriate overlay next to each other. Over the years the underlayment deteriorated allowing a critter or two to enter some parts of the attic. This, of course, resulted in repairs of leaks etc throughout the last couple of years. Argh! We selected Bay101 due to the sales, services, competitive bid and warranty. Bay101 sales to the actual roof installers on this project are so customer oriented and do outstanding work. They are on time and efficient. In addition they pay attention to detail and the result is a beautiful new roof for my building as they complete the work for the rest of the HOA. Michael and Jose are great to work with and so responsive and this behavior is pervasive though out the whole team. It was interesting to watch this whole process, especially as they load the pallets of tiles onto the first and second floor using this portable pad to navigate the large truck arm through wires on the street etc. very cool. I can't say enough about this company that isn't positive. If you need anything to do with your roof, call them. The also do roof/gutter cleaning which might be better to use and they know how to walk on a tile roof so it doesn't break. Michael (Sales) or Jose R (owner) and Mauricio or Jose (project lead) are absolutely the best! read more

Great service, highly recommended. I had new roof installed by them, looked great, no longer leaks. We didn't replace our old gutter but they still spent some extra effort get our gutter cleaned. After a few weeks I noticed an issue with our gutter positioned a bit too low. It might be pre-existing issue but I still called them, they came to take a look, even it's not likely they caused it, they still did the repair well. read more

We just had Bay 101 Roofing completed our new roof. It is quite a pleasant experience to work with the team. I chose Bay101 after doing a few research. I first went to GAF and Certainteed official websites to search for their certified roofing contractors. Then I read reviews of these contractors on yelp. I reached out to ask for quotes from 3 roofing companies who are certified by both roof brands and who received many positive reviews on yelp. Bay 101 is one of these three contractors. Bay 101 gave us a pretty reasonable price. Actually, another contractor also gave us a very close price. But we are impressed with the information package that Michael gave us at his first visit for quote. He showed us the number of roofs that they did in the past three years. There are a lot! That makes us to believe that this company is very professional. After a few emails discussing some detailed questions, we decided to work with them. The company exceeds our expectation for its quick timeline. They completed the new roof, gutters, dry rot repair, and an additional layer of OSB deck for 3 days and a half. They even work on Saturdays. The workers cleaned up everything after the work was done. They also helped us to clean the garage on the last day. The day right after the roof was completed, we passed the city's inspection! And it is within 4 weeks of signing the contract! We really didn't expect that we could get it done before November. That's terrific! I will recommend Bay 101 Roofing to everyone who are seeking for a new roof. read more

Last weekend we all know that Bay Area had very heavy rain. As property manager I was so desperate that I called almost ten roofing companies for roof repair but I can't get to talk to anyone. Just one company told me their earliest availability will be a week later. Bay 101 Roofing was the last phone call I tried. They picked up my call, and told me they probably can send a roofer to check it up that day and they will let me know the time frame when they have better idea. Later they called me back and send the roofer in the early afternoon. The roofer found the reason of the leak, they quickly solved the problem and made preventive procedure and their fee is very reasonable. As a property manager who manage 30+ properties in South Bay, I finally found the trust-worthy roofing company that I want to partner with. I won't be hesitated to recommend Bay 101 Roofing to any of my friends and clients! read more

Bay 101 Roofing - This is the leaking point - Roofing Near Me - San Jose, California

Our experience of Bay 101 Roofing was a story of excellence from the start. Jose came to estimate a roof repair for us (he was the only one who would) and when we decided to replace the roof, he returned with the most complete packet of information we could imagine, from shingle choices to previous jobs done by the company, to a list of clients to contact for recommendations. The estimate was among the best, and after some discussion of details, we chose materials. Our job was scheduled for the following week, and Jose and his crew of three came each day on time, and scrupulously took care of the area, leaving each day after cleaning up. I see remarkable attention to detail and good problem-solving. We would use Bay 101 Roofing again in a heartbeat, except we think the roof will outlast us! Many thanks, Jose, Lorena, Juan, Jose, and Adan! read more

We recently had our old shake roof replaced by Certainteed Presidential Solaris TL by Jose and his team. Michael, the sales professional, provided friendly and prompt service, quoted us quickly, and helped educate us as to the alternatives. Jose, the owner, then came to meet us and answer any other questions. The team started on the indicated day and finished quickly. They were efficient and cleaned up daily, although roofing is truly messy work. The end product came out beautifully. And it's helped us reduce the heat on our house tremendously (Ask for Low E material - Michael can tell you all about it. It really works! ) On completion, Jose asked us to walk the roof with him to show off his work. From the careful custom nailing to the ridge venting to the leaf blaster gutters. He was so proud of his and team's work. Overall, we are pleased with their work and found them easy to deal with! Fingers crossed that the roof lasts the 50 years they say, and protects from rain, wind, and sun! I do recommend Bay 101! read more

Overall, we had a good experience with Jose and his team. They arrived promptly, worked fast, and did a great job for our roof. Jose took the time and showed me on the roof the work they did and gave tips for caring for our roof and gutters. One thing I wish could have done better is if they would inform us of the debris that was going to fall into our unfinished garage/laundry room. Jose did offer to give us a $200 refund for the cleanup work, which was a nice gesture we appreciated. read more

We needed a new roof so we sought a few different bids from highly rated roofing companies. Bay 101 came back with a reasonable estimate and a clear explanation of the different choices and considerations. There was no upselling or pressure at all. Communication was clear and honest. The team worked fast, kept a clean job site, and was friendly and easy to work with. Definitely strongly recommend them. read more

I will very seldom make any recommendations because people genuinely feel they have been mistreated at some point. That being said I could not give 6 stars otherwise I would have. I contacted they want to one and contracted with them they helped me deal with an excessive amount of roof problems and gave great suggestions and solutions without question or asking for more money! I contacted eight different roofing contractors for a reroof at my home. Bay 101 Took the time and made the effort to keep tabs on my home and it's specific issues. Not one other contractor, diamond certified or not ever recontacted or had any other interest in my home or its roof status like Bay 101! If you're asking if it was a perfect project it was not. But they 101 roofing never stops its professional attitude towards customer satisfaction until the job was completely finished! I cannot recommend Bay 101 highly enough and their contact person Mike Hunt! read more

Bay 101 did our roof in Willow Glen back in 2021 and did a very professional and thorough job. Today during the rain I noticed what appeared to be a leak in one of the joints and reached out to them - they had said they would be very responsive to any repair requests. Boy were they! They came out within an hour in the rain to look at it and as it turned out it was largely due to leaves rather than any mistake they had made. They were very quick, efficient, and gracious and of course charged nothing for their efforts. A great experience. I would have recommended them for the roof alone, doubly so now seeing firsthand their great customer service after the fact. read more

I am rating Dave 5 stars and the job/customer service 3 stars, which give you an average of 4 stars! Overall I am very satisfied about this (stressful) journey. My 5-stars rating: Dave is the one who contacted me after I contacted them via Yelp. He is a really nice human being and very professional. He scheduled a first inspection with me, and did not show up (...). But you know what? It happened FOUR times to me before with other roofing companies, and Dave actually apologized! So we re-scheduled another one with him, he went up on the roof, gave us his insights and then worked on a quote. During the whole process, he made sure to answer all our questions and  he was always available by phone and/or emails. My 3-stars rating: A team of 4-6 workers came at home with their big trucks and start tearing stuffs apart. I was very impressed by their professionalism, the job took only 4 days total. There is a mid-inspection by the City, which is taking care of by Bay101. There is another final-inspection whenever the job is done. You get a nice paper saying: OK. Why did I rate 3 stars? 3 reasons: 1. I was supposed to call the office back to confirm the color of my gutters one day prior start date, they close at 5pm so I called at 4:45pm. They put me on hold for 15mins and told me that the office is now closed (5pm)... The lady I had on the phone did not want to help me at all. 2. Look carefully at the quote. They will not be responsible for any damages inside the house. I thought it usually does not happen often. But it did. Hopefully I could take care of it, but still... 3. After job was completed, they left a ladder in front of the house to let the inspector know this is the house he needs to inspect (final inspection by the City). That ladder stayed for 5 days in front of our house... read more

My shingle roof plus various damage underneath were removed and replaced by Bay 101 a couple of weeks ago. Michael was excellent to work with from work proposal to the final walk through of the completed job, and answering lots of questions in between. He was generous on the cost, considering the amount of replacement rafters that were uncovered. The crew led by Jose was professional and thorough from stripping off two layers of shingle, hauling away debris each day, putting together a beautiful new roof, and a paint job to match. The included roofer and manufacturer warranties will give peace of mind for the rain seasons. read more

The office was very easy to work with when I called to requested an appointment for a quote for roof replacement. Jose came to our house right on time. He inspected our roof and informed me that our roof would still be good for another six to eight years and did not need to be replaced yet. He also took the time to answer our questions and explain different types of roofing materials. I found him to be down on earth, honest, and experienced. We will definitely call on him again when it comes time for roof replacement. read more
