I have used this company since buying my house ...full roof repair in 1995...and again for spot fixing twice ..just recently this year 2025.... Workers came on time ..I will be using them when I need to do a full roof repair.... read more

We had a roof leak and contacted a few roofing contractors to try to figure out what was going on. Ryan came out, looked at some pictures we took of the attic where we suspected the leak was, went onto our roof, and concluded that one of the roof flashings was where the leak was occurring and that it was previously not installed correctly. He was the only one to take pictures and show us the problem and explain it. He gave us a very reasonable quote for a repair and squeezed us in within 1-2 weeks, even though it was the holidays. His crew came and was very professional, came into our attic to confirm the problem area, and repaired the roof within a few hours. Leak problem went away after! Overall, a great experience. read more

We hired A&B Roofing to redo our concrete tile roof and we had to change start dates a few times as Ryan provided helpful information to assure the work started after the rain. From start to finish the A&B crew was friendly, professional and cleaned up nicely at the end each work day. They did a wonderful job on the new roof and we're so glad we went with A&B Roofing and would refer them to others in need of roofing work. read more

We had a roof leak and were recommended A&B roofing by one of our neighbors who had used them previously to fix their leaks. Out of all the roofers that came out, Ryan was the only one who could quickly pinpoint exactly where the leak was coming from. He was highly professional as well and took the time to explain the situation and showed us pictures. He gave us a very reasonable quote and a quick timeline for the fix. The repair was scheduled very quickly and I'm happy to say my roof is no longer leaking. I'd highly recommend A&B Roofing for any leak repairs. read more

We had a great experience working with A&B Roofing on a low-slope roof replacement. Fair pricing, efficient work. John maintained excellent communication with us and was able to work through some ventilation hurdles with the City Inspector stemming from an old building. read more

A&B Roofing has earned all 5 stars with their complete re-roofing job on our large home in the Belmont hills. They won the job after submitting a bid that detailed every process, every step and every material to be used on two different sections, one flat and one sloped, requiring different techniques. We had a very knowledgable contractor review all three bids we had gotten (all top-rated by BBB, licensed firms with no complaints, etc)... he confirmed that A&B was doing everything up to top professional standards. Steve Worthington explained everything in advance, offered two recommended upgrades (an energy-saving "Cool Roof" layer and more/larger downspouts) which we selected. Their total cost was upper mid-range, not the highest we saw... and well worth the cost. This isn't an easy location... up a very steep drive then 2 more levels stacked up a hillside. Also, we knew there was dry rot in several places... so Steve coordinated with the Structural Pest contractor, removing the old roof covering, waiting 2 days for wood sheathing and facia repairs, then continuing to finish the roofing job and gutter work. Steve, his son (who was the site supervisor) and every member of his crew were exceptionally courteous and considerate. It's done. It's beautiful. We're happy. A&B is very highly recommended. read more

Wet spots in the bed are always a pain especially when they are caused by a leaking roof, such things happen after three years of drought followed by massive storms. That was the first time that prompted me to ask my contractor neighbor whom I should hire to repair my roof. He recommended A&B Roofing, and they delivered. I had to wait a couple of weeks (very common), but we got a quote, picked our shingles and they installed it quickly. The invoice met the price and they were very good at getting all of the county inspections done. The second time I hired them was because of the quality of the first time. Luckily in this case we didn't have an emergency situation, it was just that we bought a new house and the one thing needed was a replaced roof. I didn't need to check other bids, I knew they would do a good job. I would note that an entire roof is expensive, you may be surprised on your quote. They will also do repair jobs if that is possible and requested. read more

I was client supervisor for the re-roofing of a large, pitched roof on a church in San Mateo. There were above-average challenges involved, including: age of the building (100+ years), steepness of the roof, complex sheet metal requirements, sensitivity of neighbors, coordination with on-site activities, etc. A&B Roofing exceeded my expectations in all areas. Their team, from top down, was professional, courteous and accommodating of our needs. If problems arose, they addressed them right away. And they got it done on time. The entire congregation is pleased with the results. Unquestionably, I would use A&B Roofing again. read more

Used them to replace a leaky tar and gravel garage roof. Professional, timely and competitive estimate. They are usually backed up, but managed to accommodate a smaller job. High quality work, took care of obtaining the necessary permit, and promptly corrected an invoice mistake. read more

On time great job trustworthy reasonably priced good clean up no leaks easy peasy read more

A roof inspector gave me their number. Good source. I don't think he does down sil valley much or rather I am in central Santa Clara Valley. He said he would come and give an estimate but I never saw it. So knocked a star off for lack of follow through. Though if I had to do it over again I would follow up and get him to give me an estimate if he still is willing to work in non-penninsula areas. Still they have to be better than the people we used. If you start to have problems with a roofing job - don't wait - go even if it is not finished - go directly to the contractors licensing board - that is what I have learned - not that I have heard of any problems with A&B or had any!!! just an fyi in general there. read more

I would recommend this company, before above all roofing services or any other companies in San Carlos , Steve and John are great people , I'm a roofer and have worked for them , they are respectful kind people and are true to they're work , no bs read more

John did an awesome job on my 5,000 square foot roof (on a 96 year old house). The job became much more complicated than expected due to uncovering prior bad flashing work that had resulted in a lot of dry rot inside walls and around two chimneys. John and his crew worked around all the other unexpected work that had to be done (stucco removal, stud replacement, etc) and still got the job done quickly. While a few very small issues arose during the work, John was quick to take responsibility and make everything right. When my mom needs a new roof in her Mountain View house next year, I am going to ask John to do it too. Thanks! read more

When it comes to roofing, the quality of the work can be judged by how well it lasts over time. A&B Roofing rates five stars for the great job they did for us seven years ago. When we bought our home as is, the big flat roof had large puddles during rains and it leaked. John Worthington came highly recommended and he changed the drainage of the roof as well as refinishing it. Since we also wanted to add solar electricity at the same time, he worked closely with the solar engineers to sequence the two jobs and seal all the posts and conduits the solar system required. Moreover, John proved to be completely reliable and trustworthy. I'm happy to report that we have no puddles, no leaks, and a much smaller electricity bill. Thank you A&B Roofing!! read more

Called to have my roof inspected due to a leak called them up to set a appointment,waited for weeks and they never called back.Maybe they forgot but couldn't wait got another company to repair it read more

The roof looks great but there were a few things that were sloppy. Nails through a ceiling wheee there is no attic and sloppy work around the chimney. Nice people but not watching what's got on read more

I got a quote from Steve for and new roof and gutters. I was very impressed with his knowledge and price. His crew arrived very promptly each day and did a great job. When the city inspector examined the finished job he said it was a great job. To me the job was great but to here it from an city inspector made me feel great. I would highly recommend this company for any work. Their employees and workmanship is the best. read more

Great experience working with John and his team. Excellent work, fair price and *excellent* communication. Very highly recommend.

Great service, This was the second call to Steve. After a great job years before. Thank you

I had a couple problem area's on my tile roof and I needed to have my old garage roof taken off and a new one installed.

They did a fantastic job :) read more
