"I went with Sky Tech Builders on a room addition. I decided to hire this company because they gave me very realistic offer, were available in short time and I also got some recommendations from my friends. The project started soon after we signed a contract and it went very smooth, there were no issues or hidden costs. Sky Tech Builders team was professional, efficient, quick and communication was great. They finished this project ahead of schedule, quality is superb and final product is excellent. I couldn't ask for more! Thank you!"

"I have been looking to get the recessed lights done for years, but couldn’t find the right people that I could trust. During consultation, I was able to trust them with their knowledge and their professionalism, and the results were beyond my expectation. I was out of town during the installation, but they cleaned everything at the end and installation was all done without any defects."

"We hired Clever Design and Remodeling to remodel our two bathrooms and a completely new master suite. We never thought small changes would make such a huge difference our home feels like new, Roy was great to work with too. We worked with them from the very beginning when drawing out our floor plans for the project and they lived up to our expectations. In addition to having new flooring, drywall, paint, completely new bathrooms there was so much more work involved. Their taste in design is impeccable. Thank you, Clever Design and Remodeling, for making it so easy."

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