"Abraham and his team were awesome. They help us remodel our kitchen and bathroom, and did a great job. We met with several companies before starting our project, but decided to go with My Construction Group because of the great communication and clear cost structure. Abraham really went above and beyond for us! I would highly recommend them to my family and friends."

"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!"

"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$) and paint (about 40$)."

"It went well. There were some surprises. Damaged shingles and structural damage were discovered once we were underway. This lengthened the duration and cost of the project. Fortunately Sigura has carpentry capabilities in addition to their painting skills and were able to make the needed repairs before resuming the painting. The rest went without a hitch."

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