    New 3-ply ModBit flat roof with silicone coating

    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. [[HIGHLIGHT]]Peter was great to work with.[[ENDHIGHLIGHT]] 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.

    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. [[HIGHLIGHT]]He has consistently taken the time to explain everything clearly without ever trying to upsell unnecessary work.[[ENDHIGHLIGHT]] 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.

    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.

    Highly recommended. UL Roofing is great for quality, price, communication, and result. Peter is very responsive and knowledgeable. No nonsense or surprises. As owner/operator he is on the site doing and overseeing work every day. Finished result is beautiful. Co-ordinated with my solar installers to do everything at once. Color: Shadow Grey Presidential (upgrade)

    Old unit!

    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!

    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!

    Skylight over light well

    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.

    Finished roof with copper vents, flashings, bronze skylights, and solar roof mounts.

    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.

    We contacted Peter, and he came out within 24 hours to patch the leak -- and did not charge us anything extra.

I chose them for 2 major reasons. 1) they were going to deal with the scheduling of the removal and réinstallation of our solar panels. And 2) Shahar was so kind, informative, and honest during our consultation. He was through and kept us updated every step of the way. When our project finally started the crew were so respectful and kind! We found way more damage than we expected which resulted in our quote going up. However, due to Shahar being honest at the consultation we knew this was a possibility so it wasn't super shocking. The crew was great at cleaning up at the end of every day, which we appreciate as we have chickens, ducks, a puppy and cat as well as a child who are outside. When the project was done, there were a few concerns we had, we talk to Shahar and he quickly corrected and had the crew fix the items. Our roof is beautiful and will hopefully last many many years to come. I am thankful we went with Apollo Roofing and Happy Shahar was our project manager.

The job went well and he refunded me some money without me asking. Such amazing honesty and character. His son owns the company now and still a great company to deal with. They just put a roof on my son's house. We asked for some extra things be addressed and everything was perfect. They pull the permit for you and get the city inspector out for you to sign off! All included in the price. Fully licensed and insured.

I got quotes from 4 and found out quickly how much of a pain it is to look for a contractor (one tried to upcharge me and I was pretty distrustful over roofing companies after that). Fabian came super quick for a quote; offered a pretty fair price that included the scope of work; got the job done quickly; and was responsive before, during, and after the process. They finished fixing the roof in about 2 days actually (one day for the roof, one for the gutters) just in time for the nonstop rain this time around. He added vents so that the roof would circulate air a little better, fixed up the shingles, and added gutters so that we addressed all the possible ways the roof could've caused the leak. I will say in between the process since I'm super particular he answered any questions on building requirements needed, difference between materials, and general concerns. For example, the intake vents that initially were replaced looked wonky, or had stickers left over and he got his guys to replace it correctly and clean it/fix it. I noticed one of the gutters wasn't draining during the light rain and he had a guy check it out the same day-- fixed it the next. So the job close to perfect, but of course checking the work helps. So far no leaks (it's only been day 3 of the crazy rain this week) and the new gutters are draining great. They've been in business for years now and are local; if you're looking to deal with a pretty honest roofing company with no hassle, I'd reach out to them for a quote in a heartbeat.

During the teardown, we discovered that one of the walls hadn't been properly constructed originally. Cesar caught the issue immediately, and all the leaks are now completely resolved. They also uncovered some unexpected wood rot during the process, but instead of massive upcharges, Cesar gave me a very fair and reasonable rate to handle the repairs properly. As part of the project, they installed sound-absorbing insulation under the new siding. The difference is night and day--the house is much quieter now, completely weatherproofed, and the exterior looks gorgeous. Cesar is honest, highly skilled, hardworking, and possesses excellent communication skills. His team showed up, stayed on the job, and finished the entire project remarkably fast. He also handled day-to-day job logistics with total professionalism and ease. I was so impressed with the quality of their work that I've already referred them to family members for their own siding and roofing needs. I would not hesitate to hire Cesar and his team again. Highly recommended!

During the demolition we discovered that there was extensive water damage and that the source of the leak as the walls around the deck. Oscar's team repaired all the damage, installed a new roof, replaced the waterproofing on the walls, and redid the siding, followed by installation of a redwood deck. At each step he came clear explanations of our choices and options for repair and gave us a choice of deck options. The team was polite and cleaned up the job site thoroughly when they were complete. The final result looks great and is clearly much better done than the original roof. I would definitely hire them again.

I emailed a few companies with great reviews and the owner (Arcenio) of Leon Brothers Roofing not only replied quickly but he came out the next day (a rainy Christmas Day) to make the actual repairs. He shared pics with me of the roof damage and the work he did to patch it up, and said I'd need a roof replacement within a year. I subsequently contacted Arcenio last spring and got two other bids for replacing the roof; Leon Brothers came in at the lowest price. Even with additional work needed underneath the actual shingles, I saved $4-$5,000 over the next lowest bid. Most importantly, I was very pleased with the crew, the cleanup and the communication from Arcenio and his workers. They were diligent, stayed on schedule, and worked with my construction crew and painters to coordinate the work in the optimal manner. I cannot say enough good things about this company and highly recommend them!

I had a few quotes from different companies and they were just wanting to rip up the roofing on the light well and redo the whole roof. Brian came along and just said he could fix it with a corrugated panel on top and fixing the scupper like it was supposed to be fixed. The previous roofers did a lousy job and when my roof got clogged and flooded, it was just the side near the window that was leaking and caused all the water damage in the bathroom and in the garage. Brian said he could just fix it without having to redo the roof and my impression of him was that he was down to earth honest. He fixed the problem and without a lot of cost involved. His straightforwardness basically saved me a lot of money. These are the types of people I like to work with. Honest contractors are hard to find. If you have any roofing issues, I highly recommend you hire this company to take a look. Brian will give you an honest assessment and not try to get more money off of you than is necessary. That's worth its weight in gold.
