"Donna and Jeff (owners) were hands on supervisors. They both patiently answered lots of questions and provided recommendations and resources out of their scope of business.  I felt confident that Jeff and Donna knew their business well and that my best interests were being well served.  I feel confident that they will respond quickly to any questions that I may have in the future regarding this project.  I would recommend them without any reservation.  I felt like I was fairly treated and charged a fair price for their services and the system installed.  Stated scheduled was maintained with proposed start and completion dates.

"Eric and his crew arrived when they said they would, began work immediately, including moving everything from the room, stripped away all damaged subflooring and cleaned up all the mess. The next day arrived promptly, laid new subflooring and cleaned up the mess. They returned to lay the vinyl tiles and had it looking beautiful in a matter of a few hours. I could not be more pleased with Eric's work ethic, professionalism, and efficiency. I would definitely hire them again! Eric even came back and provided and installed 2 doorway transition pieces at no additional charge! It was overall a great experience for me!"

"Green Home went above and beyond what we initially expected from getting someone to build this deck for us. They were able to work with our budget and deliver what we were looking for. My husband and I are so excited to have a new, nice outdoor space where we can spend time with family and friends. Thanks green home team!"

"Shawn and his workers did another fantastic job for us. They added additional space to our pavilion deck to allow improved access to our swim spa. He has done several other projects for us that have turned out so well. He'll continue to be our first choice as we continue to improve our home."

FAQs for addition to existing structure building service projects in Louisville, TN

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.
