"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."

"After they redid our counter tops and island, we had them paint out cabinets and build shelves up to the ceiling. The communication was on point this time and the results speak for themselves. Would definitely recommend them to anyone for any home project. "

The project was finished ahead of schedule and with no unexpected extra costs. I am super satisfied with result and high quality work, thanks for everything. Highly recommended contractor!"

"After I contacted several contractors on a room addition I decided to go with Sky Tech Builders and I can tell that it was a really easy decision because they gave me great offer and they completely understood what I wanted to do. They were also available on acceptable time and project started soon after we signed a contract. The project manager and his crew were professional, honest, helpful and very respectful to me and my home. They finished project within time they promised and within my budget. And final outcome is excellent, I am fully satisfied with everything they did and would definitely work with Sky Tech Builders again!"

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