HALCO to the Rescue! After my in-laws (both in their late 80s) had their roof replaced in late 2025, concerns were later identified regarding the quality of the installation. Multiple inspections and an independent assessment confirmed that significant corrective work would be needed. When a trusted local painter noticed some of the issues, I asked him who he would recommend for an honest evaluation. Without hesitation, he said HALCO, a company that has been serving our community for more than 40 years. From the first inspection through the final repairs, HALCO was exceptional. They thoroughly evaluated the roof, clearly explained what needed to be corrected, and communicated every step of the process. Scheduling was smooth, the office staff was responsive, and there were no surprises along the way. A special thank you to Lupe and his crew for their professionalism, attention to detail, and pride in their work. Throughout the entire project, communication was clear, expectations were met, and the workmanship was outstanding. It's easy to see why HALCO has earned such a strong reputation over the past four decades. If you're looking for a roofing company that values integrity, quality, and customer service, our family had an excellent experience with HALCO.

Halco helped me fix a leak in the flashing and set up a better drainage solution plus cleaned off moss and gutters with a competitive price. The team left the area clean and walked thru their work with pictures to show before and after. Highly recommend! read more

Halco Roofing was great! I would not hesitate to use them again in the future. They replaced our roof for a rental. In our case we had the additional challenge of having the work completed by a certain time to meet our insurance requirements. Jennifer was very helpful in helping us with everything and going the extra mile to provide info for insurance. Lupe and his crew did an outstanding job in completing the roof per what we wanted and following up with inspections in a timely manner. Thank you!! read more

Lupe, Darío, and Eduardo did a great job replacing my roof. Lupe provided samples, explained what needed to be done, how they would proceed , replaced rotted wood, was considerate of my property and did a great job cleaning up. His crew was hard working and a pleasure to work with. His pricing was very reasonable as well. read more

A friend referred me to Halco for a leak I was hearing for our recent down pour. Jose was able to come out that afternoon and found our problem. It was fixed within 2 days. Jose was very pleasant to work with and very good at explaining our problem. read more

Halco roofing, specifically Lupe and his team did an exception job with replacing our roof. I consulted at least 5 different roofing companies, got quote from each of them. Among all 5, Halco Roofing stood out, both in terms of quote and also their approach to roofing. Hal, who helped me finalize the contract and scheduling did an amazing job as well. Once we had scheduled finalized, rain prediction created a last min twist but Lupe and team started a day earlier, worked longer and finished well before rain arrived. I highly recommend Halo Roofing! read more

During the storms, the holiday season, and a lot of confusion in working with insurance, it took a bit to properly connect with Halco. However once we figured out how to proceed, we had great communication with them to organize an estimate and the repairs. Very competitively priced, Halco Roofing came out and quickly assessed what needed to be done. The offered multiple options, including the bare minimum to resolve a leak and satisfy the insurance piece, as well as other value added work that could help us. We chose what we wanted without any pressure from them and agreed on the work and price. They came out and took care of the services we selected, and also took before and after pictures of everything they did so we could submit for our insurance claim. 5 star service from these guys - will certainly keep their number handy when we have any roofing needs! read more

Our insurance company notified us that they were not going to renew our policy due to roof condition. We contacted Halco based on yelp reviews and they responded timely with both repair and replacement bids. We opted for the very competitive re-roof bid. Halco had an opening in their schedule and the work was completed timely with good quality. Very pleased with experience and would use them again in the future. read more

I wasn't Stressed I was Blessed to have Jay Adrion Take care of my roof needs Jay does what he says he will do. I do not have enough good words to say about Jay and Hailco.

Jay doesn't need a red, white, or blue cape he needs a GOLD one. Thank You Hailco for employing such an honest, dependable, young man and roofing crew. I rate you a 10 for a job well done. Sincerely Nancy Neal. read more

Halco was recommended to me by a friend and neighbor. They did an excellent job re-roofing my home in Livermore at a competitive price. Hal, Jennifer and Lupe are very good to work with, taking time to address customer concerns. They are experienced professionals that gave me confidence the job would be done right. During the quoting process Hal did an inspection of my existing roof and estimating the remaining life. He addressed my questions about replacing all of the barge rafters and all the soffit vents including adding a few for better air flow. Other companies I got quotes from sent out sales people that just referred to satellite images and said I could discuss those "extra items" with the crew when they show up. That sounded too late to me. Jennifer's was good about discussing shingle options and where I could go to see samples. In the end I went with the upgraded Certain-teed Presidential Solaris on the house and two small sheds. Lupe was good about discussing the few areas of wood repair that was needed and had matching materials. The 47 year old original barge rafters on the house were weathered and cracked with rot on some ends. Rather than the minimum patching of the rotted sections, I had them all replaced. Halco used high quality trim wood in single piece runs and pre-painted them to match. This was not that expensive and it's best done with the roof. I highly recommend considering it, it made my house look new. I'm very happy with the results and happy to support a local small business. Thank you Hal, Jennifer, Lupe and the crew. read more

This is a well run family operation. Hal and his wife are a great team. Anytime we had a question, they got back to us immediately. The installation team, headed up by Lupe, were great. They completed all the work within 2 days. They were efficient, neat and very professional. We wanted the solar braces to be installed before the roof was completed. They worked very well together with our solar vendor. We love working with Halco and will make sure to let our neighbors know how pleased we are with their professionalism. Thank you. read more

Hal, Jennifer, Lupe and crew were awesome. Support local business. Thanks for a stress free experience.

I've known the owner for many years and through several jobs for family and friends. Always superior care and attention to details. Hal, the owner, cares about the quality of his company's work and is often hands on himself. Checking in after the job is done to ensure all met one'd expectations. I highly Recommend Halco for any roofing need! read more

Our neighbor recommended Halco Roofing after our insurance company wanted to cancel our policy for our roof needing repair. We contacted Hal and Jennifer and told them our situation. They went over and beyond with their support in dealing with the urgency of our problem. In a nutshell, we have a new roof that was expertly finished at a reasonable price and that met our time requirement. They worked hard, cleaned up every day and were careful and respectful of our landscape. My wife and I couldn't be happier. If you need I new roof we highly recommend Halco. read more

I received several bids while selecting a roofing contractor. I sent out a request for recommendations on a local social media site, and Halco was one of 3 recommended. From my first conversation with his wife, I was pretty sure I wanted to hire them. She was very informative and really took the time to explain the qualities of certain roofing materials, but answered all of my questions honestly. When I finally met Hal I quickly found him to be equally as personable. Within 3 days my roof and gutters look excellent, they cleaned up each day, and they even made a couple of repairs at no charge. HIGHLY recommended. read more

Thank you for your great work on replacing our roof. Hal and Jenifer guided me through the process of replacing the roof and replied to my emails and calls quickly to answer my questions. We talked to different contractors and the price was very good compared to other quotes. The work was done in three days and professionally. Highly recommended. read more

Hal was quick in responding, to give verbal quote followed by written quote/invoice before the work. Next day his crew came (lupen) came and fixed missing rake tile and covered rake-edge junction. read more

There are not enough good things I could say about Hal, Lupe, and team! Everyone had their masks on with every interaction and kept a respectful distance (roof repair work on a 2 story was done during pandemic). Went with them after a referral from a neighbor and the good reviews on Yelp. Hal worked with our budget and kept us in the loop via email, calls, and text. Lupe & team did high quality work quickly (total 1 day). The team was reliable, a pleasure to work with, and super diligent in terms of cleaning up after the work was done. Roofing is not cut and dry so expect changes to the estimate as they get started. Would highly recommend for anyone looking for repair or roof maintenance work! read more

When I bought my house, the inspection company suggested replacing the whole roof. In need of a new roof I reached out to multiple Roofers and Halco Roofing. Halco roofing was cost efficient and very professional. Hal and Jennifer (The owners) came out to my house immediately after speaking by phone to inspect the roof. They provided an estimate that was comparable to other companies. Their partner (Lupe) showed up on time and completed the job as outlined in the estimate.  They also cleaned up after themselves, you would have never known that they were there. This is a family owned and run business. They take pride in their work and reputation. read more

I've had a couple leaks pop up on our tile roof over the years. There's a number of trees around the house and the roof gets quite a bit of debris that clogs up the valleys and gutters. I had Hal and Lupe come out the first time and have since been a repeat customer. Absolutely the best roofing company I've dealt with, and one of the best companies, period, when it comes to customer service, reliability, communication, and results. Simply the best, highly recommended read more

I am in the process of selling my home and Hal from Halco Roofing was accommodating on the timing to get some repaires done that were needed. His team worked on the trim and roof matching the trim and getting the work done with no delays. Highly recommend them... read more

Halco just put a new CertainTeed Solaris roof on our house in Pleasanton, and we are extremely happy we chose them. Their bid was significantly lower than any of the other companies we contacted, and it turned out their work was exceptional. Hal and Jennifer were very easy to work with, and they helped us through every step of the process. Lupe did the installation, and he was helpful, conscientious, and very skilled at his job. There were no surprises that you often find with contractors. The job was completed on time and within the scope of the bid. Cleanup was thorough, so when they left, the only thing left behind was our beautiful new roof. We highly recommend Halco Roofing. read more

During the last big storm, I noticed water was leaking from the garage ceiling. Called Halco to get a quote. Left a message and heard back within the hour. They sent out someone to do the quote and was actually able to perform the repair right away - before the next wave of rain! He was timely, professional, did the work thoughtfully (I did not feel it was a rush job), and cleaned up afterwards. I will not hesitate to call again should I have other roofing needs. read more

We hired Harold/Hal to reroof our house in 2012. They came out and replaced it in a fair amount of time with no problems, however, every year it rains we get a leak on the porch at the chimney. Every year I call Hal to come out and fix it. He came out two times and the third time he sent someone else. He called me back the third time and told me he was "Never coming back out" He claims the problem is with the chimney but the water falls thru the roof. He gave us a 5 year warranty, has not stopped the leak and now refuses to fix it properly. Since he has refused to fix it I will probably have to go the the contractor's license board to make him fix it. I do not recommend this company. read more

I've used Halco for a job on a rental property in San Jose and again just last week on my home here in Livermore. My issue last week involved a leak that sprung during the storm. Hal was onsite within an hour or so and a few hours later the job was done for a great price to boot. Hal is the nicest guy and a consummate professional and they're a local company. I can't say enough good things about Halco. read more

I just had Halcal Roofing replace a roof on a house I own in Santa Clara. Their bid was very competitive. Hal's crew were some of the best roofers I have seen. I have done quite a bit of developing in the past so I know good roofing when I see it. I now have the best looking roof in the neighborhood. I highly recommend Halcal Roofing. read more

Unlike some situations with contractors working on my house, I was home the entire time the roof replacement project was underway, so I got to watch and inspect constantly. Work consisted of a fair amount of carpentry changes I wanted to eves and some messy bad wood replacement, in addition to the new roof. Crew workmanship was first class / crew was respectful of my property and effective at job site cleanup / no smoking / no loud music / promptly showed up every morning / worked on weekend days to get the job done quickly. Interaction with Hal and Jennifer throughout the bidding, acceptance, execution and closeout phases was exemplary. They were on site regularly to help with the work and provide q/c. Hal identified the requirement from the roofing material mfg for upgraded adhesive underlayment that I would have wanted anyway. Valley and other sheet metal work and caulking came out fine. Hal kept me promptly informed on his recommendations for wood repairs so I could inspect and approve of contract extras in advance. Hal also coordinated with his recommended insulation company to arrange for additional insulation blown into the attic while the roof was off so the insulation installers did not have to go though my house to get attic access. I'd use Hal and Jennifer again and recommend them to friends. read more

We recently had Halco Roofing replace the roof on our house in Livermore. We're extremely happy with with the result. They were very professional, easy to work with, and very conscientious.

First major rain fall of 2018 and I found I had a leak in my tile roof that was dripping into the house. I understand that the day after rain like that most roofing companies are beyond busy. Hal called me back within 20 minutes of sending out an estimate email. He told me he would be right over (that day) to check it out. He came by, looked at the damage, provided an extremely fair estimate to fix a leak in an emergency situation, and said he would send a couple of his guys over to work on it later that day. He had a team that was doing a full roof replacement close by and said he could spare a couple workers for a bit. He even left his personal ladder there so I would be reassured. Sure enough, a few hours later, he came back with a couple people. They replaced a few broken tiles from some leftover pieces that I had on hand, and fixed the leak. The whole process from initial contact to completion was about 5 hours. I couldn't wait around for the guys to finish on the roof because I had a prior commitment. So I told him I might not be around to pay them after they completed the work. Hal said it was not a problem and he could swing by tomorrow to give me the invoice. He got the job done quickly, and was extremely relaxed about payment and making sure I was happy. Plus, he is just a great person to talk to. When he came the next day with the invoice (exactly the estimate amount) we just chit chatted for about an hour about nothing in general. Cars, life, kids, etc. All around great service from a great guy. My roof needs to be replaced in a few years, I'll probably get a few bids from other companies. But you can't put a price on customer service and great people. Would recommend 100% read more
