"I had an amazing experience with Be home Remodeling, I want to thank Josh Zack's and his team of dedicated professionals for the amazing job they did on my master bathroom. Josh?s dedication and communication was crucial in ensuring the job was done quickly and professionally. He was is always available and provided quick response! We decided to do a bathroom remodel a couple of weeks ago. The entire process was done properly and as described to me at the start. Project was on schedule and went extremely smooth. The workers and staff were really professional, polite and easy to work with. I highly recommended BE Home Remodeling and specifically Josh Zack."

"I highly recommend hiring Adrian Kovaci and his crew at Ceres Construction for your home construction project.The quality of their work was superb, the cost was comparible to the three other quotes I got from other companies, and their work presence at my home was unobtrusive as I could hope for. My two level 1923-built Richmond district home in San Francisco had a derelict passage to my garage - crumbling door, wobbly side stairs, and dry-rotted siding. Nothing was up to code. Adrian noted all the items that had to be reconstructed and said the project would take up to 20 days (it actually was finished in 18 days.) Adrian was very accommodating in giving extra finishing touches to my door hallway without extra charges, which I appreciated. I was concerned about the cost of the project and the disruption the work would cause, but Adrian's calm demeanor and the friendliness of the crew put my worries to rest. Thank you Adrian for leaving the work area spotless and for the quality work!"

"It was a pleasure to work with Eric, we hired him for a complete backyard renovation which included tree removal, leveling the surface and place pavers and a deck on top. Also built a retaining wall. The work came out very nice in part because of the great design ideas that Eric gave us. The project ran into some unexpected issues that Eric was able to overcome nicely. We were impressed how Eric handled the project and met all the deliverables, also his team was extremely polite an professional. Our backyard now looks like the ones advertised in magazines. All this led us to start a new project with him to replace the cracked driveway with nice new pavers."

"We recently remodeled our bathroom with McCormick, and it was a fantastic experience. Khaled was informative, patient, and genuinely helpful, guiding us through choices for a perfect design. The team’s professionalism showed in their punctuality and quality. Every aspect was done with care, from tile placement to lighting. The transformation is truly impressive; the bathroom now feels open and luxurious. We’re beyond pleased with the result and look forward to more projects with them."

"If you’re thinking about getting a new roof, definitely go with Build Atlas. I’m in my mid-20s and had no idea where to even start, but a neighbor recommended them and I’m so glad that they did! The whole team was super friendly, down-to-earth, and made the entire process way less stressful than I imagined. They showed up when they said they would, kept everything clean, and finished faster than I expected. Plus, the roof looks fantastic — it’s like my house got a facelift! It’s rare to find a company that’s this easy to work with!"

FAQs for addition to existing structure building service projects in San Rafael, CA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
