"I’m very satisfied with the exterior painting that Jonathan did for me. He communicated well with me and has a lot of experience and overall knowledge. He is fairly priced and even saved me money by painting/repairing my fence instead of replacing it which I had thought was not a option but looks great! I have a lot of projects to do around my place and when I’m ready to start another one I would trust Jonathan to help me complete it again."

FAQs for addition to existing structure building service projects in Kapolei, HI

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.
