Top 3 modified bitumen contractors in Alviso, CA

"After the last big storm we had, our roof took a beating — leaks everywhere, shingles missing, and water spots starting to show inside. We decided to call Martin & Isaac from Balcorp Roof Repair & Commercial Roofing and honestly, it was the best decision we could’ve made. They really know their stuff when it comes to **Santa Monica roofing**. They helped us go through **FEMA**, walked us through every step of the process, and even helped us secure a pretty large chunk of the repair cost through the program. They pulled all the necessary permits, kept everything clean and organized, and handled the **roof replacement** like total pros. After today’s storm rolled through, not a single drop made it inside — the roof held up perfectly. If anyone’s looking for reliable **roof repair in Santa Monica**, Martin & Isaac are the guys to call. They made the whole experience easy and stress-free."

"Just finished getting a new roof with Roof Repair Specialists. Great experience. Can't say enough good things. Did exactly what they said they were going to do and at the price they quoted. No surprise add-on fees. Everyone involved, including Grace and Aaron were fantastic. But a special shout out to our project manager, Alvaro. He was the absolute best. Couldn't be happier and can't recommend them highly enough."

"I hired RRS back in February 2025, after suffering damage from the January wind storm/wildfires and meeting with several roofing companies. They were the obvious choice from the start. Noah came out to do a thorough inspection of my roof and showed me photos (proof) of the damage and what was necessary to repair everything the correct way. He took the time to explain the RRS company values, how the project would go and the materials they would use (I got to pick what would fit into my budget). He was a pleasure to work with and I instantly felt comfortable with what initially felt like to me, a very intense process. Roof repairs/replacements are some of the larger expense repairs on a home and I wanted to make sure it would be done right and up to code. Noah was on the same page. After much back-and-forth with insurance (special shout out to owner, Chris, for being on top of everything and for his constant and thorough communication with me throughout this process), the project got underway in June and went as well as Noah promised. I think I got the best QC manager - Alvaro - and install team. Seriously incredible and knowledgeable guys. I can't thank them enough. My home is old and historic and he understood and took the most care with all things throughout the replacement process. They showed up right on time, every day, and got the job done. Super impressed with the everything. Thank you again, guys! I've had a lot of work done on my home in recent years and nothing has gone as smoothly as my roof replacement. This company and team is a class act, all the way from the team that answers the phone to the guys installing the roof. I always recommend that homeowners do their research but be sure to give RRS a call. You'll be happy you did."

"Erik and Alvaro were both very helpful as the field supervisors, staying in contact and sending me pictures daily as the project progressed. The job was done on time and very well done."

"They installed a new skylight and improved our attic ventilation. The team was professional, courteous, and made sure everything was done correctly. My home feels much more comfortable now."

"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."

"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."

"Journey builders did a great job with fixing my roof. Yero the project manager was very professional and explained everything very thoroughly. They were very quick to start and I am very happy with the results. Will be referring to my friends and family. Thank you Yero and the journey builders team"

"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!"

"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 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."

"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!"
