"If you’re considering a bathroom remodel, look no further than California Designers Remodeling. I had a fantastic experience with them. Ray Vanunu, the project manager, was an absolute gem to work with—friendly, knowledgeable, and always available to address any concerns. The team’s attention to detail was impressive, and they delivered a finished bathroom that feels both luxurious and functional. The entire process was hassle-free, and I appreciated how organized and well-communicated everything was. It’s clear they take pride in their work, and the results speak for themselves. I couldn’t be more pleased!"

Addition to existing structure building services FAQs

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.
