3 Best Roofing Contractors in San Francisco, CA

We recently hired Roofworx for a full flat roof replacement on our property in San Francisco, about 1,200 square feet, and the experience was excellent from start to finish. Vlad and his team were professional, clear with communication, and very knowledgeable about flat roofing systems. The old roof was removed and replaced efficiently, and the new flat roof installation was done with great attention to detail. The job site was kept clean, the work was completed on schedule, and the final result looks solid and well-built. If you’re looking for a reliable roofing contractor in San Francisco for a flat roof replacement, I highly recommend Roofworx inc.

I had a small leak on my low-pitch shingle roof and contacted Roofworx Inc. for an inspection. After a thorough evaluation, they explained that the issue was caused by improper roofing materials being used for a low-slope application. Instead of just patching it, they recommended the correct solution: installing a modified bitumen roofing system designed specifically for low-pitch roofs. They clearly explained why shingles are not ideal for low-slope areas and why modified bitumen would provide better waterproofing and long-term protection. The installation was done efficiently, cleanly, and with great attention to detail. Since the repair, we’ve had no leaks at all. I really appreciate their transparency and expertise. If you need low-slope roof repair, leak detection, or modified bitumen installation in the Bay Area, I highly recommend Roofworx Inc.

We worked with Roofworx to redo our roof. The roof was not a standard re-shingling. We wanted to add insulation on top of our existing exposed beam ceiling to preserve the beauty of the wood. The insulation was desired because our roof did not have any insulation and during sunny days in the summer it would be quite uncomfortable inside. They worked with us to get all the details right and in the end our roof is quite nice. It is very comfortable inside and looks great.

Quality service from start to finish. These are very professional experts in roofing. I was impressed with the way the analysis and estimates were provided and explained to me. It was nice to see drone footage of the areas they would address. Then the crew who came in did an amazing job of getting the job completed quickly and thoroughly with constant communications even with a daily photo log of the repairs. I highly recommend Mr. Roofing.

Great experience from the initial consult all the way through the installation. Everything was properly explained during pre-install consultation, all questions clearly answered, challenges addressed. The installation went smooth and quite fast. Didn't even have to be present aside from letting the team into the building. The skylight works great, gave us extra sound insullation and replaced and old, foggy skylight with a beautiful clear one that lets a ton more daylight into the room. Very happy with the experience and the final result. Thank you.

I love the 50 year materials guarantee! The crew was respectful and hard working. They showed up on time and made sure to accommodate my comings and goings. We got to test out the roof since it rained intermittently throughout the work schedule. Everything functioned perfectly.
