"Mark and Jake were fantastic to work with. I met with three different contractors to get ideas and proposals for my deck, and Mark was the only one that proactively followed up with regular updates and explanations for any delays out of his control (e.g., from suppliers). They were also very helpful in providing ideas and suggestions. Jake also went above and beyond: we had wood rot on our original deck after only 5 years, and Jake volunteered to figure out who supplied the original wood, went in person to meet with the supplier to understand why it would have rotted, and he sent me a warranty claim form and instructions from the supplier to get a reimbursement for the rotted wood! I’ve never worked with any service provider that’s provided that level of service. I highly recommend ITP Renovations."

Customers say: Quality work

"Pablo is the best contractor I have ever hired in my life (age 67). He gave reasonable estimates in a extremely professional way. His subcontractors to do the tiling and excavation did perfect work done expeditiously. They were no nonsense but very friendly and were frankly, a joy to have around the house. My bathroom belongs in a design magazine. In the lifetime I have left, I will hire Pablo and Simplicity Construction for any construction job for everything this house needs. He is also a terrific guy. On time, within budget, beautiful work, friendly and dependable work. What else is left?"

"The process was very Professional. Greg came out and evaluated my old shingles roof and gave me a price to install a new metal roof. He was very informative concerning my change over from a shingles roof to a metal roof. Greg explained the step by step installation process and the warranty that was included. After an agreement was confirmed, I was always notified with everything from the material drop off date and time to the actual installation date and any delays.. Will definitely use Southern Signature Solutions in the future for other Home Projects!! Wonderful Customer Service! Thank You Mr. Greg Carter And Crew!! MY NEW ROOF LOOKS GREAT!!"

"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.

FAQs for addition to existing structure building service projects in Griffin, GA

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.
