"Their team did an awesome job in building an additional room out of our large game room upstairs. They were very respectful and professional throughout the process. Answered all our questions and made sure we wanted exactly what we asked for. I would highly recommend this team to anyone looking to do any upgrades to their home. Pricing was fair and install was quick and easy."

"We are extremely pleased with the quality of work done by Eli and his crew. The quality and passion was evident in everything they did. Our neighbors have noted the beautiful addition to the front of our home and gone out of their way on praising the front garden border. In fact two of our neighbors want to hire them!"

"I was so excited with the work Unique Remodeling did for me. I had been trying for nearly a year to get a remote controlled electric attic ladder installed. Most I talked to had no idea they existed. I company never even started it even after collecting my deposit. When Albert responded to an online inquiry, I was so impressed with his professionalism & enthusiasm, Albert kept me informed of every aspect of the install. He is highly skilled & knowledgeable. What he’s unfamiliar with, he thoroughly researches. High quality, reliable, aesthetically pleasing work. I also needed grab bars installed in both of bathrooms. I asked Albert if he could install. Again friendly, professional, quality, prompt workmanship. In all that he does, I witnessed a high level of attention to detail and efficiency in completing the jobs with minimal disruption. Albert did an admirable job cleaning everything up and removing all debris. I highly recommend Unique Remodeling & Floor Design!"

FAQs for addition to existing structure building service projects in Seguin, TX

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.
