"WOW!! I am impressed!! Osvaldo Molina and his crew managed a beautiful finish on my parent's roof. He was great, very calm, collective and informative through out the whole process. Osvaldo helped answer any questions I had and explained every detail needed. As a the field manager for my parent's roofing project, he provided high quality results and even touched on areas not listed as a courtesy. I am very grateful and feel blessed to have someone like Osvaldo manage our roof repairs. Also, a big shout out to Bo Hovanesian!!

"Lucio and Ronald came out today to install 2 solar vent fans and perform some roof repairs. They suggested a better way to mount the garage fan and it works great. They noticed some repairs that were needed that were not on the worked order. It was done at no charge. They are true professionals at what they do. I am 100% satisfied with the job they performed."

"Working with Darah Roofing from beginning to end was a great experience. Unlike other companies I called for a quote, I got a call back from Darah Roofing within minutes and they came the next day to give me quote. During the quote, Jorge (the owner) explain to me the entire process, what to expect, and timeline. He definitely knew what he was doing and instantly got my trust. Especially after getting another company to give me a quote before Darah Roofing, the other company was not as thorough as Jorge. I gave Darah Roofing the job, they finished a my 1100 sqft house within 3 days. Looks amazing. My general contractor saw the job and was happy with the work and asked me for Jorge's contact information as he would like to use him in his future jobs. A general contractor to ask for this information was another assurance that I hired the right roofing company. I would definitely recommend Darah Roofing."

"I’ve worked with Darah roofing to replace my 20y old roof. I gave them a call, and the next day Jorge and his father came for an onsite inspection. One day after that they’ve sent me a quote, that was very competitive. We’ve talked through all the details and made some adjustments to the project. After I’ve signed the contract, we’ve agreed on the installation date and Jorge filed the paperwork for the permit. At the day of installation, the crew arrived on time. They’ve covered the pool, all windows, deck and tile around the house to avoid any damage to the property. They’ve removed the old roof, did some repairs to the plywood and we’ve successfully passed the first inspection. In 3 days I had the new roof fully installed. They’ve also added a layer of thermal insulation, cleaned the gutters and put the protective covers on it. 2 days after the installation was complete, I had the final city inspection, and passed it. Every day, before leaving the site, they’ve cleaned after themselves. Jorge was very responsive during the project and attentive to the details. I’m very happy with the results and can recommend Darah roofing to anyone looking for a roofing contractor in SF Bay Area."

"It is an excellent experience working with Jorge (Darah Roofing Owner) and his team, actually I did not know them before the roof and gutter replacements. They did a very detailed and careful job, and also paid a lot of attention to your property as well. I am more than happy to make a great recommendation for them."

"Darah Roofing installed an exceptional quality GAF composite roof with ridge attic venting. The work included careful removal and disposal of our old shake roof. Darah Roofing provided timely install of the energy efficient LP Techshield Aluminized OSB, Tiger Paw Underlayment, Pro Starters, Flashings, Vents, High Reflectivity RS Composite Shingles, plus all Gutters and Downspouts (subcontract). We will now be saving money on energy with the new thermally efficient roofing. Enrique kept in close contact throughout the process and made the extra effort under tight scheduling constraints to finish the job within a few days -- right before heavy downpouring rains. He brought on additional teams and experts to accelerate the work to finish on time and at budget. Great Job ! Highly Recommend !"

"Jorge replaced two roofs one after another for me recently. He’s very responsive and communicative. His crew were working diligent and finished the job on time. I’m very satisfied with their work. Looking forward to working with Jorge team in the future."

"We had been thinking about getting the roof and insulation done for couple of years. We looked for contractors and found Journey Builders as one of our options. Upon meeting with Zack, the project manager, we decided to do the roof with them. They had, in comparison to other estimates, a fair price. However, it came down to how comfortable we were with their transparent process. The process was fairly smooth and easy going. The roof was done in a timely manner and they worked really hard to finish everything before the rains started again. Overall it was very easy working with them and we would definitely recommend to work with Journey Builders."

"We are so happy with our new roof! For the last few weeks, we haven’t really gotten to know this company and the people who work for it and are so happy with their service. When they did our roof, they had uncovered bad work that previous roofers had done before us, where they had patched up spots instead of using new materials it had sold it to us as otherwise. They have been really kind to our family and gave us a great deal on a great product. I would definitely refer them to friends in need of a new roof."

"I recently bought my first house, and it was a bit nerve-wracking, especially knowing I needed a new roof and had no idea where to begin. I reached out to several companies to compare pricing and customer service, wanting to find one I could trust. When Journey Builders Roofing sent Ramon, I immediately felt reassured. He was kind and took the time to explain everything I needed to know about getting the right roof. Ramon and his team were efficient and professional, and I’m so glad I chose this company. I’ll definitely be recommending Journey to my family and friends."

"I had a ton of leaks on my roof, so when I starting looking into roofers, Journey Builders popped up on my screen. I saw they had great reviews on google and yelp, so I decided to take advantage of their free estimate. I called them up and had a appointment the next day, the girl that I spoke with was very polite and professional, When the roof specialist came out, he took a look at my roof and showed me pictures and was very thorough in explaining the process of changing my roof. He have me a great price and seemed like he knew what he was talking about. When they started my project, they were very fast and efficient, the guys clean up very good and the process was more seamless than I anticipated. I definitely will recommend them to my friends, when they need their roof done!"

"Chris and Will were so nice. They told us a price and when the construction would start and end. They kept in touch throughout the roofing project. The crew they sent completed our job and it looks fantastic. They left no mess to clean up."

"We worked with Roofworx to redo our roof. The roof was not a standard re-shingling. We wanted to add insulation on top of our existing exposed beam ceiling to preserve the beauty of the wood. The insulation was desired because our roof did not have any insulation and during sunny days in the summer it would be quite uncomfortable inside. They worked with us to get all the details right and in the end our roof is quite nice. It is very comfortable inside and looks great."

"Had a stubborn leak on the Spanish-clay tile roof at our cemetery site in San Francisco. ROOFWORX booked us the same day, swapped the cracked mission tiles, laid high-temp underlayment, and rebuilt the flashing—all without disturbing the historic look. First Pacific rainstorm: bone-dry ceilings, spotless grounds. If you need tile-roof leak repair, waterproofing, or full roof replacement in the Bay Area, these roofing contractors deliver. Five stars."

"We had a small leak in our roof. Sam at Roofworx came by to examine the roof and provide a quote. He was on time and provided an excellent explanation of what he discovered and our options to get the roof repaired. Their quote was one of the most detailed and best priced bids for the project. We hired them to do the section tile reset option. The work was promptly scheduled and it took a bit over a day to complete. No problems were encountered. The roof has performed well during the past couple of storms. At the end of the job they were able to provide pics of the work. I would definitely recommend them."

"We had a fantastic experience with Roofworx! They provided excellent service from start to finish and installed our new roof in just one day. It looks amazing! We worked with Quentin who was wonderful. Great communication, easy scheduling, and he handled everything smoothly with our insurance company. The shingle options were great, and the final result completely transformed the look of our home. Highly recommend Roofworx for anyone needing a new roof. Professional, efficient, and high-quality work!"

"We just completed a full roof replacement with Mike Smile and his crew, and I couldn’t be happier with the entire experience. Mike was patient as we got started, worked with my schedule, and gave us the best quote we found after comparing multiple contractors. At the very beginning, he took the time to walk us through the whole roofing process so we knew what to expect, which really gave us confidence. We had multiple layers of old roofing that needed to be stripped before installation, and his team handled the demolition in a single day and installed the new roof right after. They work fast, they’re professional, and they keep the property clean throughout. Any time something came up, Mike communicated immediately and worked with me to resolve it — no hesitation, no excuses. In the end, the results exceeded my expectations. I highly recommend Mike and his team for anyone looking for a reliable, knowledgeable, and hardworking roofing contractor."
