"My friend recommended My Construction Group and when I saw how many positive reviews they have I sent a quote. I got response very soon and estimate next day. I was satisfied and decided to hire them. The project was building an addition 250 sq. ft. Before start Ariel explained me every single detail about project and that was very professional from him. He and his crew were really great, worked hard, kept eye on everything and cleaned after themselves. It was a big project so normally there were some issues but nothing serious and they finished on promised time. Excellent work guys, highly recommended company."

Customers say: Quick response

"Zacharias Remodeling Construction did an outstanding job remodeling my mom‘s kitchen in July 2025. Oscar, the contractor, was professional, responsive, and easy to work with from start to finish. His team was meticulous with every detail and always arrived on time which made the entire process, smooth and stress-free. This was especially important to me as I had experienced a contracting company in the past where the workers did not show up on time (or at all), cut corners, and it made for a lousy 2 months. The finished kitchen looks beautiful and without hesitation, Zacarias remodeling construction will be my first call for future projects."

"Excellent experience. The price was fair, Ofer was very flexible and responsive to what we needed, and his team were punctual, professional, and efficient. When other contractors would take days to respond and provide estimates, Ofer always got back to me in a couple of hours at most. Adding the skylight took only two days, and the only additional cost was for the skylight itself (about 200$) and paint (about 40$)."

"I had a second storey addition completed by Rose Remodeling, and the results are truly amazing. The team did an outstanding job blending the new structure seamlessly with the existing architecture so that it looks like it was always part of the house. Adir guided us through every step, answered all of our questions, and kept the process stress-free. We now have the extra space we needed, and the work exceeded all of our expectations. Highly recommend their services."

FAQs for addition to existing structure building service projects in Livermore, 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.
