We had UL Roofing replace our roof in 2021 after an atmospheric river revealed many leaks. The install was fast, the crew was pleasant, and the work held up exactly as promised: five years, zero leaks, zero issues. When I reached out recently about a check-in inspection, Peter flagged something I hadn't thought to ask: our solar panels (added 2022, post-install, by a different company) had penetrated the membrane, and he wanted to get eyes on it in case it had become a problem. He offered to come look even though follow-up visits aren't part of his standard service. We recommend without hesitation. read more

We had an exceptional experience with UL Roofing and couldn't be happier with the results. From the beginning, Peter (the owner) was knowledgeable, friendly, and highly professional. He took the time to answer our questions thoroughly and provided a fair, transparent quote with no pressure or surprises. What truly set UL Roofing apart was their integrity and responsiveness. Before our scheduled service date, we experienced a roof leak. We contacted Peter, and he came out within 24 hours to patch the leak -- and did not charge us anything extra. That level of care and going above and beyond is rare and speaks volumes about the kind of company they run. The crew completed the full roofing job in just 3 days -- one day ahead of the original 4-day estimate -- without compromising quality. The workmanship is excellent, and the final result exceeded our expectations. Since the roof work has been completed we've been through a week of heavy storms/rain and withstood with no issues. If you're looking for a roofing contractor who is honest, efficient, skilled, and genuinely cares about their customers, I highly recommend UL Roofing. We would absolutely use them again. read more

Peter of UL Roofing was the highest of three bids to replace my roof in San Francisco, but was only $2,000 more than the cheapest bid and his approach gave me the most confidence -- so I chose to contract him. He said he would be working on the roof himself and on-site every day; he described the job in much greater detail than other bids, and explained where my trouble spots were located; and he spent much more time photographing the repairs needed. By contrast, the middle priced bid simply surveyed everything with a drone, and didn't even go on the roof (that was an immediate red flag). The cheapest bid gave very little detail on the condition of the roof, and simply submitted the bid. At any rate, he completed the job according to the projected timeline (5 days) and the final bill was only $300 more than the original bid (some wood needed to be replaced, which is standard and explained up front). He and his crew also did my neighbor's roof three weeks later, and by all accounts, he is happy too. The one negative: The work around the skylights created some mess inside the home interior -- unavoidable, but a warning would have been nice. read more

Peter and his crew were the perfect crew for the job. Arrived on time every morning and cleaned up everything before the end of each work day. The job was finished a day early and I'm grateful for him and his crew for the hard work they put in. Would recommend their services to anyone! read more

I would highly recommend UL Roofing. They replaced our very old modified bitumen flat roof and added a silicone elastomeric coating. Project was completed on time with no problems. Peter was great to work with. We've had a number of contractors in for various projects on our new house over the past year. The owners of many contracting companies do the initial consultations and get the contract signed, never to be seen again. Not the case here. Peter was on site every day to supervise the project, start to finish. read more

Thank you Peter for coming to inspect our roof. We will continue to refer your company to our neighbors and friends.

Peter and his team at URL Roofing are truly exceptional. Peter has come by my home multiple times completely free just to check for leaks and make sure everything was safe. That level of honesty, patience, and genuine care is incredibly rare. When it came time to replace the back part of my roof, I didn't hesitate to hire him because I trusted his work and his integrity. He and his team did an amazing job. The new roof looks great, and the quality of the work shows in every detail. They were efficient, respectful, and made sure everything was done the right way. Peter also went above and beyond by sealing exposed gutter nails and checking areas that could cause future leaks. He has consistently taken the time to explain everything clearly without ever trying to upsell unnecessary work. If you're looking for a roofing company that is honest, reliable, and truly cares about its customers, URL Roofing especially Peter and his team is the best choice. I highly recommend them. read more

Highly recommend UL Roofing, especially its owner Peter, who was straight-forward, honest, communicative and follows through with both the plan and estimated costs. My 2200 sq ft roof was replaced recently, changed from tar and gravel to modified 3-layer Bitumen. I interviewed several companies, after studying their reviews, and decided on UL Roofing because Peter seemed clear about his plan, his cost estimate was comprehensive and reasonable, and his office is in SF, versus the 5-6 other also highly-reviewed Bay Area companies I found off of different websites/apps. Peter was clear about the scope of the work, took 3.5 days to remove my tar/gravel roof and then, day by day, applied the layers of the new roof, replaced my skylight and gutter, and cleaned after their work was done each day. The final cost even stayed the same as his initial cost estimate. I will certainly recommend Peter and his company to my family and friends. read more

Been meaning to post this review! UL Roofing Inc did some solid service on our roof last year. Absolutely flawless work. It's been super windy rainy lately and we lost one of our vent caps. Called in for a quick fix, before the rain came back. They came through with a prompt, professional and great job! They even replaced the whole unit! Not just the cap. For the best value, you can count on them! read more

UL Roofing recently completed my roof replacement in DC for our rental. Working in DC is extra difficult, iykyk. UL Roofing is by far one of the most responsive and communicative contractors I've worked with to date. Their price was competitive to competitors. One of the biggest troubles with working with construction is communication with contractors. What stood out is Peter's (owner) honesty. He was very transparent as far as scheduling, concerns about unforeseen conditions, impacts to occupants, and willingness to help out. He offered to help with any interim leaks from the old roof due to weather conditions and scheduled work. He even followed up a few weeks after the work was completed to see if we have any issues. I would definitely recommend UL Roofing and would for sure use them again for other roofing needs. Get the quote and commit early, as it's always surprising how many people need roof work! read more

Peter is a very professional and timely. He answered all my questions and provided solutions and recommendations for my current issue and general roof care. He had great communication, arrived as promised and promptly addressed my roofing issue.

We worked with Peter & his team after moving into our new home in the Sunset and discovering after a winter of heavy rain that our roof had a lot of small leaks and was overdue for replacement. Despite being very busy with the heavy rain, Peter responded quickly and gave us a good quote, his fair, thorough, & organized assessment stood out compared with other roofing providers so we went with him fairly quickly. A few months later during the summer he & his team replaced the roof within a week, working quickly & efficiently. During the replacement he discovered some water damage that he quoted to repair at a very reasonable price. He also proactively suggested we integrate solar panel stanchions since he knew we were planning on getting solar. We were very happy with the resulting roof & experience. Our roof has a lot of small clay tile detail areas that are detached from the main roof. The following winter we saw some remaining small leaks and let Peter know. He again responded quickly and was able to discover the leaks in these smaller areas and patched them in a few hrs. After that, no leaks and now we have a relationship with Peter that we're grateful for to keep the roof maintained over the long haul. read more

We interviewed several roofing companies to replace the existing flat portion of our roof along possible shingle replacement. Peter was very timely, knowledgable and professional. I had many questions and Peter answered all of them via email. His reply times were excellent. We also wanted to consider replacing our center patio corrugated cover with a skylight as well as the one over our bathroom light well. The posted pictures on yelp let us know that he was very familiar with this type of addition to our center patio. The completed project did not disappoint. Peter and his team cleaned up at the end of each day. The completed center patio skylight needed extra ventilation as well as an assessment with morning mist water getting through the frame. Peter was very responsive to this and contacted the fabricator of the skylight to assist. Another timely response. The cost was competitive to other folks we interviewed. It was expensive but his work provided 3 ply bitumen system vs other's 2 ply system. You get what you pay for. Peter has definitely earned my trust. It is hard to find a good trust worthy roofing company. UL Roofing has earned this trust with my family and I. I would recommend UL Roofing to anyone needing any roofing work. read more

Highly recommend this company and not only for the quality of the work, but for the fact the owner, Peter Choung, is there with his guys all day to ensure the highest quality control. I live a couple blocks from the beach in the outer sunset, where aluminum turns to dust and galvanized metal completely rusts through within 20 yrs, and Peter was able to offer copper roof flashings, bronze skylights, as well as all the other vents for my roof made out of copper. I also had solar installed just after the roof was completed, and Peter did not charge me extra for waiting for the solar company to install the mounts, as well as the added work of sealing the copper flashings that go around the solar supports. I had a lot of delays due to another siding project that had to be completed first, and Peter had no issue rescheduling me back to a time for me to finish the other project (twice). Another item that sets UL Roofing apart from other roofing work that I've seen done, was the fact they wrapped and sealed my cast iron plumbing vent pipes to stop further corrosion. I can't say enough about this company and the fact that I will refer them in a heartbeat to anyone that needs roofing work in the salty corrosive areas of San Francisco. read more

UL Roofing did an amazing, thorough job with our roof replacement project. Peter and his team were the only group among six other companies I contacted who showed up on time for our initial price estimate appointment. Peter was also very responsive to our questions and extra requests and I was impressed with his patience. We actually forgot to inform him before starting the project that we installed a new drain pipe that we wanted him to attach to the new gutters. But he was willing to return a week later to finish that part with no extra charge. Overall, UL Roofing gave us the best price for our project as well as a great experience. I highly recommend them if you want a respectful, punctual, hard working team. read more

Peter and his team did a repair in the past which held during this past winter's storms. But we had some new problems.

I got an estimate from Peter on a new roof, and he was honest in telling me that I did not need to replace the roof now, even though it's 25 years old. His bid also included some less expensive options that would save me money without compromising the life or integrity of the roof. I decided to replace the roof anyway because I'm installing solar panels, and used another roofer mainly because of timing (Peter could not get to me in time for the solar installation). However, I was very impressed with Peter's honesty, professionalism, and responsiveness to my numerous questions. When I need roofing work again, I will definitely call Peter, and I highly recommend UL Roofing. read more

This winter's storms finally brought an end to the life of the old tar and gravel roof, with mission tile sections, in my San Francisco home. I contacted half a dozen roofers, of which UL Roofing was the most professional and thorough in analyzing the situation. Peter came personally, identified deficiencies in the old roof, and provided a thorough and fair estimate for the work. As it turned out, unrelated and unexpected circumstances put the project on hold before it could begin, but Peter was wonderfully understanding. I would recommend Peter to any homeowner looking for roof work. Trust is a precious commodity, and he earned mine. read more

If, right now, you are doing what I did - searching Yelp! for a highly reviewed roofing company - look no further. Peter is *exactly* what you want in a tradesperson: responsive, reliable, honest and does great work. I live abroad and every trip home involves undertaking maintenance on my elderly Mom's house. My trips are short and pressurised. Peter was able to come over within a few days of contact via Yelp! There were a few aspects to this job not to mention very tricky access at the back of the house (downspout needed replacing) due to the location of my Mom's house. He sent me three clear, reasonable quotes before I left the country and gave me honest advice about the parts of the job that I could do later (we are not flush with cash). We were able to book the job in via email with a family member providing access on the day. He turned up with his guys on time and completed the work exactly within the time frame he stated and sent me photos on the day. Highly, highly recommend him and will definitely have him back to replace the skylights when I have the money. read more

Amazing service! I had UL Roofing do the roofing for my parents' house during COVID. Peter took all the necessary precautions by giving us plenty of notice when he'd come by (with masks on of course) and if/when he'd have to enter the house. He was also always very quick to respond as I liaised my Asian parent's inquiries and concerns. The job was done quicker than estimated even despite a few hiccups, and the roof and new skylights look great! Peter was honest about what needed replacing and what didn't, and from contract-signing to finish, everything was pretty straightforward. I highly recommend UL Roofing to anyone who needs a new roof, and I would gladly do business again if I can ever afford my own house in SF. read more

Peter and his crew broke all the norms of contractors. They kept me informed of their schedule and work progress. They showed up when the said they would. The cleaned up after their work.

Very friendly and honest family owned roofing business. My family is out in San Francisco and their house was leaking around the sky light. I contacted this business and they were quick to respond.

They offered to show where and what the exact problem/ source of the leak was. They came out and patched the leak within 1 day. No more leaks in the house and we are very happy with the result.

They installed a new membrane on our roof some 7 or 8 years ago. When water began dripping through my ceiling I called them and they were extremely helpful and polite. They were able to accommodate my schedule and come quickly. They had to wait for the rain to stop and made a plan to come on a Sunday as I was leaving town on Monday. Ultimately something came up and they had to reschedule to first thing Monday but I really appreciated their kindness and willingness to help. In the end it was some caulking that had come loose from the wall (it gets ludicrously hot on our roof) and they replaced it, as well as recaulked any other potential spots. For no charge. I highly recommend this company. read more
