"Couldn’t ask for a better response to our request, signing the contract and having the work completed. Bryan is very conscientious and diligent in his work and professionalism. He always kept us appraised of what he was doing, how all was going, and if there were any additional issues that needed to be addressed. Bryan never left the site without making sure everything was clean and in order."

"From my very first phone call, Tim was extremely helpful and eager to assist, clearly explaining the process and answering all of my questions. Jim visited first to assess the project, and I explained that the work would involve remodeling an existing built‑in furniture unit and transforming it into a functional home office. He fully understood the scope and offered practical input based on his experience. Jim completed the work on time and to a very high standard, with excellent attention to detail and overall quality. The transformation from the original built‑in to the finished home office exceeded my expectations, both in terms of craftsmanship and functionality. It was a pleasure working with Tristate from start to finish, and I would not hesitate to highly recommend them."

"Our time with Turner Builders has been amazing from start to finish! They demolished our old porch and built a beautiful screened-in porch. Dave and Bob were fantastic to work with—Dave had great ideas and Bob kept us updated every step of the way. We're thrilled with our new porch and can't wait to work with them again on future projects. Huge thanks to the whole team!"

"Gary & Fred were very professional. They were friendly and courteous and arrived on time. They went above and beyond in doing the work which they completed on time. They even installed a new front door knob and deadbolt when the original one broke which is not what they were contracted to do. I would definitely recommend them to anyone."

FAQs for addition to existing structure building service projects in California, KY

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.
