Customer Reviews

Chelsey Wilkinson

Troy and the team did an outstanding job replacing our roof in San Francisco. Our home looks great now, and we really appreciate their professionalism from start to finish. They guided us through every step, including handling all the insurance details and even talking directly with the insurance company to make sure our roof got replaced. The crew arrived on time, worked efficiently, and made sure to leave everything spotless after removing two layers of old shingles. We’re extremely satisfied with the whole process and highly recommend them if you ever need roofing work done!

When we bought our house in San Francisco, our home inspector told us the roof needed to be replaced soon since it was reaching the end of its life. After looking into our options, we decided to upgrade from shingles to a metal roof. We met with a few different roofers before choosing Bay Contractors & Roofing to handle our new metal roof and install half-round gutters. Troy answered all our questions before the job started and helped us understand the different types and gauges of metal, what kind of maintenance we’d need, and what the installation process would look like. We really appreciated his knowledge, since we aren’t roofing experts and wanted to make the right decision for our home. We also had a lot of questions, and Troy was always patient, making sure we felt comfortable and informed throughout the whole project. The installation went smoothly and the crew kept everything tidy while working. We are very happy with how our new metal roof and gutters turned out—they look great and give us peace of mind for years to come. A few months after the work was done, we noticed some water had made its way into a bathroom exhaust fan. Even though the job was finished and paid for, Troy made sure the problem was fixed right away at no extra cost. They replaced the fan, repaired our ceiling, and even touched up the paint inside our home. This really showed us how much they care about their customers, even after the work is done. If you want a roofer who treats your home like their own and goes the extra mile, we highly recommend reaching out to see what they can do for you.

Kyle Rodgers

i had a wonderful experience working with this roofing company in san francisco. after a big hail storm, i needed a new roof and already had insurance money ready, so i called around for a few estimates. some other companies gave much higher quotes, but this company offered a fair price and had great reviews, so i decided to hire them. even though they were busy and scheduled out several weeks, it showed how much people trust their work. from start to finish, they communicated clearly, showed up on time, and did a fantastic job. troy and the crew finished my roof quickly—about 37 squares in just six hours—and made sure to leave everything clean. working in the california sun isn’t easy, but they handled it like pros. i definitely recommend this team to anyone in need of roof repairs or a full replacement. they are honest, professional, and truly care about their customers. the only thing i’d love to see is if they could get certified to install certainteed shingles, since i like those options and their warranties. overall, a great roofing company that takes pride in their work!

A few years ago, we realized our 2-story house in San Francisco needed a new roof, as the old one was showing its age. After getting several quotes, we chose this roofing company because their estimate was by far the most affordable, and they included high-quality, long-lasting shingles in the price. We were really impressed by how quickly Troy and his crew completed the reroof—they finished the whole job in just two days. They made sure to leave our property spotless afterward, which we really appreciated. Troy also took detailed photos of the finished roof, which helped us when providing information to our homeowners insurance. Thanks to this, we received a great discount on our insurance premium. Years later, we noticed a few shingles on a steep peak had cracked. We reached out to the company to see if they could fix it. Troy came out and reroofed the entire peak area for us. When I later asked about the invoice for this repair, he let us know there was no charge for the work! If it were possible to give more than five stars, we definitely would. The service, quality, and care from this roofing team in San Francisco truly stand out.
