We had a leak in our mud room after the latest rain storm. UL Roofing was able to come out the next day to assess and seal the leak. Peter was punctual, professional and had very competitive pricing. I would highly recommend UL Roofing to anyone with roofing needs.

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.

Contacted Peter about replacing my roof. He was very professional and was quick to answer my questions. His team did a great job. Would definitely recommend to my family and friends.

UL Roofing is a solid company to go with. Peter Choung, the owner, is very easy to communicate with and professional. Peter came out to my location and assessed the condition of my roof and made solid comments and suggestions. I would not hesitate to hire UL Roofing.

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.

New owner cuts corners. Don't recommend this company. He promised the same looks of the roof, but he Failed to do it. The new roof leaked even more. We had to hire a new roofer to do all over. No one wanted to fix that leak.

Peter was very efficient from quote to completion. His offer was competitive. Construction and cleanup were right on schedule and done right. He and the other workers are highly recommended!

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.

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.

We worked with UL Roofing to replace our roof and install a skylight over our atrium. Peter and his team were fanastic. Peter was very communicative, offered a fair price, and was able to schedule our job within a couple weeks of reaching out to him. His team was efficient and friendly, and everything looks great. Definitely recommend working with UL Roofing.
