Thiago and his team did a great job installing our new roof and insulation. They worked efficiently and professionally and their pricing was extremely competitive. Highly recommend them and wouldn't hesitate to use them in the future. Thanks ELM! read more

My partner and I happened to get a leak in our roof in basically the luckiest possible place, so we saw it as soon as it started and it wasn't serious yet, but obviously we still needed it fixed. So we got in touch with ELM Roofing and had them come out to do an inspection. Lucas was great. He identified the issue quickly, stepped us through what our options were, and kept us in the loop the entire time. He checked the roof out with a drone, since it was too high to run a single ladder up, and we got to watch the neighbor's resident hummingbirds go nuts trying to threaten it away. Evidently hummingbirds hate drones! We had our entire roof and the garage roof replaced, because the builder had cheaped out on underlayment materials and is a pain to get to fix anything under warranty. So, y'know, forget him, but this isn't a review about him. We've got a much tougher underlayment now, all the chipped tiles we had have been replaced, and it is quite honestly better than new now. They did clean work, too. Didn't mess up the yard at all, they were fastidious about noise levels and allowed work times, everything you'd hope a certified contractor would do (but do they? Well...many don't, believe me). Quick and thorough, and when the project got interrupted by rain, they kept us informed about that, too. They came out on a Saturday to get ahead of the weather and even let us know exactly what the local weekend construction ordinances were ahead of time so we'd know what to expect. I think that's what I'd say about them the most: No surprises. They don't do anything unexpected with the final invoice, they don't jerk you around, they don't treat you like you won't understand what they're doing. You're fully in the loop at all times and you're treated as a partner in the project. You get exactly the work and quality promised. And it's good work, with a 20 year guarantee. I'd highly recommend them. read more

Quoted me $10,700.00 for a small leak repair that I paid another company $1,600.00 to fix. If you have a simple leak these are not the guys for you. They don't want small jobs and they will try to talk you into replacing half the roof! Update: Derek has been calling me repeatedly about my 2 star review. The facts are Derek quoted me almost 11 grand to fix that leak! You guys were way out of line. No other quote exceeded $3,600.00. It is my opinion that you don't want small jobs and were not the right fit for me. I'm entitled to my honest opinion and that's how I feel about it. All my roof needed was the mortar patched, and the hole fixed. There was nothing wrong with the underlayment. We checked! The company I hired patched up ALL the holes in the mortar on the whole roof and replaced 19 broken tiles in addition to fixing the leak for $3,600.00. To just fix the leak would have been $1,600.00. That is an appropriate quote for a simple leak, not what you did. read more

I can't say enough good things about ELM Roofing Contractors and their manager, Matt. We recently had the roof replaced on our ADU and the whole experience was very good. The quote was reasonable and the team was responsive. During the tear-off we requested that they take out every old nail so that the plywood was perfectly smooth and ready for the new underlayment and they honored our request. They worked efficiently and kept everything neat, the whole project was finished in two days. Throughout the project, they kept us in the loop, showed up when they said they would, and made sure everything--from scheduling to inspections--was handled smoothly. We really appreciated how organized and easy they were to work with. I'd happily recommend ELM Roofing to anyone looking for a dependable, professional, and genuinely pleasant team. read more

ELM and Refael specifically saved the day, again! We had an issue with the city around our downspout that was causing us enormous grief, as we could not figure out a realistic way to meet the ask from the city. Refael suggested we bring the inspector back and the two of them worked out a great path forward. This was the second time in a year where Refael helped us out in a jam. Thanks! read more

If you need your roof replaced I can highly recommend ELM Roofing Contractors. Our home had a 20 year old tar and gravel flat roof (~4000 sq ft) that had sprung small leaks the past two years. We decided to replace the entire flat roof as well as an 800 sq ft pitched roof that had ancient wood shake shingles, and solicited bids from 5 companies, including two we had previously worked with. We selected ELM Roofing not because it was the lowest bid, but because of the professionalism of Derek, the Estimator who also became our Project Manager. Recognizing that our flat roof had areas that did not drain consistently he designed an approach to introduce a small pitch from the house center towards most of the drains which are on the outer perimeter. We elected to replace the tar and gravel flat roof with a 3 ply system using modified bitumen roofing material; we chose aged wood colored shingle for the pitched roof. Derek navigated the permits required efficiently and effectively. The communication between he and myself as well as with the team of roofers was excellent; we received frequent updates including work in progress photos and drone videos. The crew cleaned up every evening before leaving which was greatly appreciated! We are very happy with our new roof and whole heartedly recommend speaking with and using ELM Roofing Contractors. read more

The project manager Thiago and the whole crew are very professional throughout the entire project. I got daily update, quick reply to every inquiry from Thiago, who makes the process smooth and stress free. read more

The quote was competitive, the team was professional, responsive, and clearly very experienced. The roof installation was done neatly and efficiently, and the final result looks fantastic. They kept the job site clean, communicated well throughout the process, and followed through on scheduling and inspections. We really appreciated how organized everything was.

We first hired this team to repair sections of flat roof on our 12,000 sq. ft. Commercial warehouse building. They did an outstanding job, the work was completed on schedule, the site was kept clean, and the entire process was handled with professionalism and efficiency. Because of that great experience, we hired them to replace the roof on our 6,000 sq. ft. home in saratoga, which included flat sections and some very challenging angles. Once again, they delivered excellent workmanship. The crew was prompt, organized, and incredibly professional, and they maintained a clean job site throughout the project. They also repaired areas of our balconies, and the quality of the work was excellent. Communication was exceptional. Thiago - Project manager kept us informed every step of the way, explaining progress and next steps so we always felt in the loop. If you are considering any type of roof repair or replacement, I highly recommend this team. We will definitely use them again in the future. read more

We had a great experience with ELM Roofing replacing our old leaky roof. Thiago was really communicative and had all the answers I needed for my first big renovation project as a homeowner. He was great at explaining the process and keeping me informed about the permits and timeline. He was able to schedule us a full 6 weeks before another company I also got a quote from, and ELM's quote came in less than that other company. This allowed us to have a new roof before the rainy season started here in Half Moon Bay. The work itself was completed surprisingly quickly in just 3 days, and we even had a double roof which required extra demolition and they had to fix up quite a few places that had dry rot. The men who did the work were respectful and did cleanup after the job was complete. Our roof looks fantastic now and we won't have to worry about it for a few decades. I recommend contacting Thiago and ELM if you are needing this type of work done. read more

When the first rains hit a few weeks ago, the roof leaked. It turns out the workers clogged the trap for the roof drain with their construction debris. When I called them, they sent out Milton who contacted a plumber to unclog the drain within a few hours. Milton returned a week or so later and added tar and roofing where the drain from the first floor roof, passed through the wall into a downspout down to the garage roof. We'll see whether that fixes the issue. I knocked off one star for clogging the drain and not checking it but they did respond quickly when I called them so they still get 4 stars. read more

Rodrigo did a very thorough job while inspecting my roof. From all the contractors that came by, he and his team were the only ones to take the time to really look at all sections and determinate what needed to be done without guessing. He also did an amazing job explaining the process and the different materials and pros and cons of each. Communication afterwards was also great. We ended up going with a different vendor because we were also doing solar at the same time and it turned out a lot cheaper that way, but I would have totally picked them otherwise. read more

We had a great experience with ELM. Max was super knowledgeable and from start to finish, walked us through every step of the process, answered all our questions, and made sure we were comfortable with everything before moving forward. The installation was quick, and the quality of the new flat roof really shows. Since having it installed, we've noticed a huge improvement in our home's temperature where it's been 10-20 degrees cooler inside, and we've barely had to run our AC this summer. That alone makes it well worth the investment in 80mil TPO away from standard torch down. Highly recommend this company for anyone looking for reliable roofing work! read more

I would like to thank Lucas and his team by replacing my roof. I talked to multiple roofing companies before deciding to go with ELM Roofing. They were not the lowest nor the highest bid, but decided to go with ELM because Lucas answered all of my questions and concerns about the replacement and installation of the new roof. It was important to me to understand the process and was reassured my questions and concerns would be followed up. The new roof installation was not a smooth process, but everything came together and completed. I'm completely satisfied and happy with the work, the tidiness of the job, and its appearance. Even my neighbor dropped by and complemented how the roof looks. Thanks again Lucas for managing the roof project as it made my stress level manageable. Thank you ELM Roofing for my roof replacement and having a great team. Highly recomended. read more

I hired ELM Roofing to help renovate my flat roof. Rodrigo was wonderful to work with, very patient, communicative, and flexible. I considered both a reroof and silicone coating, and Rodrigo worked with me as I thought through the options. Their prices were very reasonable, and it is clear that they are experienced and an established company. I especially liked that Rodrigo has experience in solar. My roof work was related to a solar project, and it was fantastic that he knew what to expect there. (Verdict is still pending on the solar company.) The foreman Alvarro was also really good and experienced, and pleasant to work with. To improve quality, they included extras like polyester(?) webbing at the edges of the roof, which I appreciated. I hope this roof lasts for a long time. When it's time for a re-roof I will start with ELM. read more

Thiago and his crew from ELM Roofing were great. They completed the removal of the old roof in one day and cleaned up all their roofing debris that made it to the ground daily. I got drone pictures of the work progress each day. They finish the entire reroofing in 4 days. The best part was when the city inspector came by I got to chat with him and he commented on the quality of the work being done (and he mentioned that he was a former roofer by trade). I highly recommend ELM Roofing--Thiago and his crew certainly lived up to their very high Yelp rating . And their price was more than fair.

I've been putting off getting our roof replaced for way too long. I was worried that since we have solar installed, it would complicate the process. We evaluated multiple vendors and ELM was the best vendor who gave us the most peace of mind. They not only offered us the most thorough in-person inspection (most companies just remotely used AI), but they gave us the best competitive price as well. Thiago was assigned to our project and he was very professional, clear and friendly in guiding us throughout the process. We ended up doing Roofing and Insulation with ELM and we couldn't be happier with the results. Big shoutout to Thiago and team for making this an extremely easy and painless process. I would highly recommend them to anyone looking for high quality roofers! read more

I was lucky to find Refael and his team from ELM roofing to work on my roofing project this year. This is a complicated project since we are adding framing for insulation and ventilation on top of the roof. There are also electric, hvac and solar involved. I prepared for the project in the last couple of years. However, my previous contractor walked away last minute due to the rain (and the anticipated project duration) in September. Before I give it up this year, I found ELM Roofing had the right qualifications, and Refael was able to start project the same week I signed the contract (including arranging sub-contractors). Looking back, this would be a challenging project to finish without Refael's coordination and dedication to it. His team (Francisco and Edgar) are hard-working professionals. I liked Edgar's attention-to-detail on the installation of shingles, gutters and air vents. The new roof looks amazing, and it has gone through a few rainy days without a problem. read more

I recently had ELM Roofing Contractors replace my roof and I'm really impressed with the service I received. Carlos came out to give us a quote and was very knowledgeable and professional. What really stood out was that he noticed a few places where water may have been penetrating the old shingles. Seeing that there was a storm coming in a couple days, Carlos went above and beyond by adding tarps to my roof the same day he gave me a quote, which gave me peace of mind as the storm came through and we had to wait for better weather to start the project. The work itself was done quickly and efficiently. My only minor complaints there was some minor work that needed to be fixed, and we did experience some leaking into the house overnight when the old roof was off. Both of these are common with getting a new roof installed, and ELM Roofing Contractors was quick to fix these issues. Everything looks great now. Overall, I would highly recommend ELM Roofing Contractors and particularly Carlos. They're a reliable and professional company that stands behind their work. read more

Reached out to a few different companies for a quote to replace a roof for a house in San Leandro and my dad was genuinely more impressed with this one out of all the rest because they were prepared with showing him options of shingles, went through what timeline looked like, and had their project manager there on their first meeting. They communicated with us from start to finish and got the project completed as they projected. When something came up outside of the original quote, they were transparent and we were able to work something out and got it done. So far, we are very happy with working with ELM and the whole team had been great with open communication, transparency, and great work! read more

I went with ELM roofing at the recommendation of a neighbor. The quote provided was fair when compared to the few others I had received and I feel extremely satisfied with the work that was done. Sean and his team were professional in our interactions and in their workmanship. They also cleaned up before leaving each day which I appreciated a lot. Pretty sure my driveway had never been cleaner. Sean was also super patient walking me through the process, helping me choose a color, and answering all of the questions I had (I had a lot). I'd definitely recommend this company and would not hesitate to use them again if the need ever arises. read more

We engaged ELM Roofing to fix ~1.2ksqft of flat roofs on our house this winter and they did a phenomenal job. My project manager was Sean and he was professional, courteous, responsive, and knowledgable. I never once felt like he was trying to over-sell me on any of ELM's services. He took a ton of time to explain the various issues with my roof and went above and beyond to help us fix troubled spots on our 2nd floor patio. Based on the research I did, I also found their pricing to be fair and transparent. If you have roofing needs in the bay area, look no further than ELM! read more

Wow, where do I even begin? My roof was beyond repair--it hadn't been replaced in over three decades since I bought my home. To make matters worse, it has steep roof pitches and no vertical sides. So, I thought taking on this job for them would be like taking a masterclass. However, Elm Roofing Contractors quickly exceeded all my expectations. They dispelled my fears that their sales pitch and offer was too good to be true. Working with them ultimately turned out to be a masterclass in integrity and quality work, for me. From the very first overview with Amir, the project manager, who is respectful, professional, personable, and transparent regarding potential problems and how it could possibly change the price - to the quality workmanship of the entire crew, Elm Roofing Contractors truly knocked it out of the ball park. Byron and Jose in particular, were always in beastmode as they worked on my roof from about 8 am to after 5 pm, sometimes even until 7 pm. Their work was exceptional. Elm Roofing Contractors are awesome and true to their word. The price was fair and the quality of work was above and beyond what I could imagine I would refer them without hesitation, and to anyone without question. read more

I highly recommend Lucas and ELM Roofing. Exceptional experience all around. Upon returning to SF from a holiday trip, we discovered we had a very bad roof leak caused by the recent winter storms. Our master bedroom ceiling was sagging and had pooling water on the drywall. Not a great experience coming home from a trip. I called a few companies on Dec 31 to come out and provide a quote, and fortunately Lucas with ELM Roofing was available to come out on Jan 2. The holiday week and multiple storms caused some availability challenges for other companies. Lucas was on time, very professional, and notably used a drone to get great photos of our roof. I appreciated his use of technology which enabled him to show us how poor of a condition our roof was in. Whomever our prior owners were definitely didn't maintain it very well and did a pretty poor job of patching it up. It looks like there were 3-4 repair jobs at various points. It was very clear we needed a new roof and it was not going to be a quick repair. I signed the contract on Jan 5 and Lucas started on the permitting process with the city. He also provided me with the documentation I needed to get my HOA's approval (they were also great). After coordinating with the city, Lucas scheduled our roof repair for Jan 16. The day before the roof replacement, Lucas and I chatted about what to expect for the day, including making sure we got permission from neighbors to use their parking spots. The roof repair took just one day (~10 hours total), which was fantastic. Here is an overview of how it worked. - Demolition: The demolition team arrived in the morning around 7:30am and finished removing our roof by 8:30am, though it was already partially gone on its own base on the photos. The demo team had their own disposal truck and were extremely considerate about the debris. They did a great job cleaning up. - Prep: The next team spent about 3 hours getting the roof ready for installation. Lucas arrived during this window to check on the project and make sure everything was going okay. - Delivery: A large truck with a crane arrived around 11:30am and delivered the roofing materials. It had a conveyer belt to deliver supplies directly to the roof. It was really cool to watch, and I didn't get much work done as I was just staring at the supply deliver for an hour. I went outside to check it out as well, looking like one of those dads in auto commercials staring at workers doing their jobs. The truck was off the street by 12:30pm. - Installation: The team spent about 4.5 hours installing the roof and were done around 5pm. So from my first call to roof replacement was 2 weeks. That was an extremely fast turnaround considering that involved waiting out the storms to finish, getting permitting with the city, ordering and getting supplies delivered, and getting the HOA to sign off. Really A+ work from Lucas all around. He project managed everything and came by in person to check the finished project to close out the project. If you have a roof issue, I highly recommend Lucas and the ELM Roofing team. read more

It was an absolute pleasure working with Amir, Claudia and the ELM team. We had not one, not two, not three, but four old roofs rotting over our heads with really steep pitches. Amir showed up, gave us a very precise quote, explained all the affiliated costs and process and what they'd need from us. As soon as we paid the deposit, we were able to schedule within a week and the work was completed in six business days. (They also provided financing options as well, which was very much appreciated.) Something critical to note: they were not the cheapest offer we received, but were absolutely competitive. That said, we opted for them because of their professionalism, preparation work they did on the site, warranty and the thorough service they provided. For example: when scrapping off four layers of roof, sometimes an old shingle falls where it shouldn't. In my instance, on an apple sappling and on my livin room ceiling. I immediately told Amir and the team replaced the drywall the next day, came to paint the day after, and found my exact sappling and replaced it the day after that. No additional charge and offering nothing but grace in the process. They're insured, bonded, have an outstanding warranty on the work and did an incredible job. I highly recommend them! Worth every penny! read more

I need to replace an old roof, and add a skylight. I got reference from my friend, who just had her house roof replaced to contact ELM.

Thiago , helped to set up the schedule for the project. Everyday, he updated me with the scheduled work and progress of the project. I was quite impressed by his work knowledge and his professional approach in dealing with problems encountered. The work crew was also great ,together the project was completed on time.

I'd give more than 5 stars if I could! What an absolutely amazing experience! From the moment I reached out through Yelp, my experience with ELM was fantastic. The request was responded to very quickly and the next day Celio came to the house to discuss options and needs. From the time that I reached out to ELM to the time the project was fully complete, only a little over three weeks went by. They had to remove 35 solar panels, strip off the existing roof, replace three skylights, put down a new roof, and reinstall all 35 solar panels. The price was absolutely reasonable for the work that was done and was on the lower end of middle of the road compared to the other companies that gave me a quote. And the customer service could NOT be beat. Working with Celio was so easy and made what can be a challenging project into a very easy one. I strongly recommend ELM for any roofing needs! read more

Tamir met up with my mother & husband to provide a quote for her mobile home w/sky light to be reroofed. He was on time, polite and helpful. She was particularly concerned about the skylight and they did inspect it and indicated it was good to stay. Once she chose ELM for the job Rafael became the project manager. ELM worked with the government to get permits, which took quite a while due to it being a mobile home and the inspector coming from Sacramento.. When she called for updates throughout the job they did respond quickly. They brought color samples to her in person and left them with her so she could get management approval. Her neighborhood will not allow dumpsters and ELM was very helpful in bringing a dump truck to receive the old roof debris as it was removed and drove it away the same day. They removed the old turbines, covered the holes, and installed a newer style of vents. They worked quickly and efficiently even in our extreme early fall heat waves. They also sent her photos and video from the roof so she could see the work. She is very pleased with the work and level of service ELM provided. read more

We got our roof replaced recently, because it was quite old, and leaked after heavy rain. ELM (Thiago) came onsite quickly after we requested their service to assess the roof's condition and recommended a replacement. The previous roof was not just old (and leaky), but also used an outdated design & material. Thiago and team worked quickly once we received permit from the city. It is absolutely critical for us that they got the repair done before Christmas, because it rained very heavily around Christmas. I am certain that had the project got delayed, our home might be flooded during Christmas, considering the weather condition. Generally speaking, doing roof work in the rain season (winter) is difficult, but they were able to get the work done so quickly, in a perfect time window between two rains. Thiago and team also ensured that all trash and debris were properly hauled away immediately after the job. read more

Had a roof leak, so I had to get 3-4 estimates to make sure I could make the right decision. Roofers are pretty competitive so in my case they were easy to schedule all on the same day. The problem they all share is they are booked out at least 4-6 weeks so be aware of that; however if rain is forecasted they usually will give you temporary coverage until they get to the actual installation date. Max was the rep for ELM, and he was very knowledgeable, helpful, and friendly yet efficient. He used a drone to survey the roof, and showed me the pics immediately. His bid wasn't the lowest but he offered the better materials and a slightly better delivery date. So there was a slight delay due to slow materials delivery from the manufacturer but it wasn't an unreasonable amount of time. The actual installation took only 3-days, and everything dropped was completely cleaned up before the crew left. Very happy with ELM's results and Max is a great rep for them! Highly recommend!! read more
