Recommended Customer Reviews

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.

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.

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.

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.

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.

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

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

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

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

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!
