    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. 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.

    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.

    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.

    From the very start of my engagement with Attic Bros it has been fantastic! I found them in a…read moresearch on Yelp and no joke, my 8 year old calls me Bro, so figured I would fit right in with the Attic Bros! I think within maybe 20 minutes of submitting my Yelp quote I had a call back and an appointment. Michael came out and did a THOROUGH inspection of the attic took a ton of before pics. But not only that he then sat down with me and went through the entire process, which is quite frankly, amazing. He also answered all of my questions and offered some input on my ducts. He made himself available for any other questions too, which was so nice since my husband wasn't around - there's always another question. With this process, not only do you get your old attic crud sucked out, they look for and seal any entry point for critters. They add mesh from the inside plus they go around the whole perimeter from the outside of the house too just to make sure they caught all entry points. They seal all air gaps from things like recessed lights and fans. And then they sanitize. Something about knowing my 70 year old house got a deep clean is VERY satisfying for my OCD cleaning tendencies. The insulation went in - they use a batting that is 12" thick, my attic before probably had an inch, maybe 2 in spots of the old blow-in stuff which was just dust and dirt and disgusting. This batting is eco-friendly - no pink artificial coloring, just the insulation which also is no longer harmful. Night one and I already saw a difference. Usually when it gets cold at night by 2:00 am our home temp inside drops, we stayed a steady temperature throughout the night, I might be a bit crazy, but it feels like there's a sound dampening effect too - I don't have to have the TV on as high of a volume. Follow-up, they add traps and will come back to monitor in a couple weeks to make sure there is no activity. Another over the top customer service layer - we had Jordan as our project/site manager for the day - I was texted by the system with his picture, LOVE this feature, its really helpful. And he called when he was closer. He kept me updated throughout the day and was just really kind, very professional and the crew he brought, Jesse and I did not catch the other gentleman's name - they worked so incredibly hard, and efficiently. We really appreciated this crew, they were amazing. If you are hesitating for any reason to get your insulation in your attic done - DON'T - it is 100000000% worth every dollar, which by the way is an incredible value when you really think about what it does for your home. I am quite mad at myself for not doing it sooner, but certain things had to happen first, so here we are! I would choose Attic Bros in a heartbeat and whole heartedly recommend them!

    Did a complete Attic clean up and R44 blow in insulation & in wall insulation for an old 1959…read morehouse. I would say, they did an excellent job - Starting with Jeremy, who accommodated my schedule for preliminary inspect and gave me a on the spot quote. Elder and the guys did an excellent job in covering up the entire house and finished the job in 2 days. My house had no insulation in the walls- to very less in the attic. After the insulation my Heat as well as Cold is retained inside the house. Heat turns on once in a 24 Hr cycle vs multiple times in an hour previously. If you are thinking of in wall insulation, it's totally worth it. The quote was the most competitive and they were very flexible. I am still closing out the multiple holes in the wall, will take time as i prefer to do it myself- I had plans to paint anyway .

    I was initially impressed with what seemed like a thorough and well-considered estimate. It felt…read morelike the team really evaluated my attic and cooling needs. The addition of two QuietCool fans also seemed like a major plus, as I was already familiar with the product and expected it would significantly help with cooling. When it came to the insulation work, I was very pleased. The crew did an excellent job removing the old insulation and installing the new. They worked efficiently, protected my floors well, and ensured that no insulation debris entered the living areas. That part of the job was handled professionally. However, I was less impressed with the radiant barrier installation. This may partly be due to a misunderstanding on my end, as I expected a different type of material, but the end result did not meet my expectations. The biggest issue, unfortunately, was the installation of the fans. At best, it was very poorly executed. The fans are 16" units with 12" duct openings, yet they were installed directly against the gables, which severely restricts airflow. Proper installation should have included a box or shroud to help direct airflow effectively through the fans. Because of this poor airflow, the fans do not cool the attic--in fact, they appear to make things worse. I can actually watch the temperature on the thermostat increase when the fans are turned on. I reached out to my representative multiple times, but the response was disappointing. I was told they could not take the fans back, and when I asked why the attic temperature increases when they are running, I was told there was no explanation and nothing further could be done. As temperatures continue to rise, I'm left frustrated that I spent $1,200 on two fans that perform the opposite of what was promised, with no meaningful support or resolution offered. UPDATE: After posting my initial review, I was contacted by both the project manager and the owner. I reiterated the reasons for my frustration, explaining that my review reflected my honest impression of what I saw as a lack of clear communication and effective management of the project and customer expectations. The project manager apologized for the communication breakdown and asked if I would be open to giving them an opportunity to make things right. A technician was then sent out, and he took the time to fully understand the issue, carefully examine the installation, and make several adjustments to the original work. He believes these changes will help improve airflow in the attic. Since my attic has some unique characteristics, he also provided helpful suggestions for additional ways to improve cooling and airflow--something I feel should have been addressed during the initial planning stage of the project. Whether these changes will result in significant improvement remains to be seen; I'll have a better sense once the weather warms up. I do appreciate the follow-up and the willingness of the project manager to reach out and try to make things right, and I have updated my review accordingly. That said, I want to be clear that the increase in my rating is largely due to the technician and the time he invested in evaluating the full situation, as well as both implementing and proposing thoughtful solutions.

    Beyond easy experience with Chris. My dryer suddenly started giving off a burning smell, which I…read moremistakenly attributed to the lint catch being overloaded. But even after cleaning it out, the smell wasn't going away. Then the vent started giving off either smoke or steam, and in a panic I immediately turned off the dryer. Thank God I didn't start a dryer fire. The second I shut it off and made sure everything was ok, I opened Yelp and searched for a dryer vent cleaner. Chris's Insulation came up, he had great ratings, he was super close by, so after calling a different service and going to voicemail, I called Chris. Chris picked up after the second ring. When I told him that I needed someone to clean our dryer vent and what had happened, he said he could come out either between 5:00 and 6:00 pm that evening or the next day. It was already mid-afternoon when I called, so I was surprised to hear him say he could still come out same-day, but I decided to have him do that since I was free and also still a little shaky following what happened with the vent either smoking or steaming. Chris showed up during the window he quoted and wasted no time getting to work. He started the second he arrived and was done within the hour. His pricing was incredibly reasonable and fair and so far, in the couple of weeks since he was here, we've had no issues with the dryer. Before he left, he also sent us a ton of pictures of what the vent looked like post-cleaning. Super happy and relieved.

In the back of my mind, I've been stressing that the sawdust and debris could be creating a fire hazard. We got an estimate from another company that shocked us and found Chris Insulation on Yelp for a comparison quote. He came out to our house (in Sac) the next morning, suited up and spent about 15 minutes getting pictures and measurements of the attic. The quote was nearly $3,000 less and he was able to do the job the very next day. The team came by the next morning while we were gone and removed all of the debris and old insulation, vacuumed/sanitized, rodent proofed and air sealed the entire attic, cleaned out our dryer vent (for free), and replaced all of the insulation, including around our skylights. There is zero evidence that their crew was even here - the garage is spotless and the attic looks amazing. I am so relieved that we found someone so fantastic and that our job is finally taken care of.

The estimator's in-person presentation was very good -- professional, clear, and well organized. The overall process was explained pretty well however I needed more info after he left.

I tried to follow up with the estimator to get clarification and asked for a call back. While multiple emails were exchanged from what seemed to be the corporate end, there was no actual human interaction, and my request for the estimator to call back failed. Because of that lack of follow-through, I ultimately decided to go with another vendor who was more responsive. AttiCare made a good first impression, but communication after the initial visit failed. I wouldn't proceed without speaking to the estimator. They lost a job due to that.
