"Ray and his team are my go to contractors when I need work done. I have now worked with California Designers Remodeling four times (since 2008) and I am thrilled with the results. I hired them again this year to build out a new kitchen, bath, laundry room/pantry . They created this stunning new addition They also enclosed the carport to give me extra garage space, which has been incredibly useful. All of the workers are professional and courteous."

"My husband and I had a ton of work done by Conber Construction and we couldnâ t have asked for a better experience. The scope of the project includes roof, windows, electrical work, exterior wall, tankless water heater, building a new gate, among other things. The project took a few months and it went smoothly the whole way through. Quality of work - Weâ re picky people. Between my husband and I, we checked everything with a fine tooth comb. And at the end of it, even WE were delighted with what we saw. Cesar does everything he can to make sure you're getting what you want. And he delivers. This was apparent from the very beginning. Heâ s got the experience and know-how to achieve what the customer wants, and he really cares that youâ re satisfied with the work. Price - Their quote was very reasonable & fair, and they stayed on budget. We definitely feel we got our money's worth. Strong communication - Customer service is very important to me. Iâ m happy to say, these folks are very responsive. I could reach out at any time with questions or comments and felt very supported throughout the whole process. Even at the very end (when some contractors can peter out), Conber was with us the whole way through. You just donâ t see this kind of customer service anymore. Ideas - When we were stuck and looking for ideas, Cesar and Fabiola were always so helpful. Between Cesar sharing what he has done on other projects, and Fabiola searching for ideas & possibilities online, we got great guidance from them. Construction crew - All their workers were very nice and & respectable. I felt very safe with this team in and out of our house (even during covid!). Very clean, neat & tidy. This is important to keep neighbors happy. Flexibility - We added projects along the way and they were very accommodating. Overall - Our entire experience went so well! The house has been transformed and weâ re constantly getting compliments from the neighbors and friends as they come over! We plan on doing more work on the inside of the house next year and we will, for certain, be reaching out to Conber Construction. Highly, highly recommended."

FAQs for addition to existing structure building service projects in Highland-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.
