"Larry was very timely in his response and quick to send an estimate. He was very thorough in his explanation of what was necessary to fix my home. He also matched the color of my other pillars in the front of my home perfectly. A neighbor even came over at the end of the repair to get a estimate on some work for his home! Thanks, Larry!"

"We hired Harrison to put in a new fence in our backyard to enclose our property, he not only did a great job with the fence but he was very good at communicating with us when he would be by doing the work, leaving, or if something had came up. Would definitely rehire."

"Beaver Home Renovations were a pleasure to work with and did a superb job at a very fair price. They were respectful, timely, and did excellent work in an expedient manner. They were flexible and accommodated additional requests that we made as the project progressed. They also point out ideas that could improve the project, as well as suggested cost saving measures. We will hire them for all future renovations and home improvements we have."

"I had two bathrooms remodeled. This included new tiles in the showers, new vanities with new faucets, new plumbing fixtures in the showers and painting of both bathrooms. All jobs were performed well and I am very satisfied with the results. Work was completed in a reasonable amount of time and pricing was also reasonable. I can certainly recommend this company."

"I had damage to my ceiling that needed prompt attention. Alex came out the same day to assess the situation, explained what needed to be done, cleaned up the affected area, and provided a clear estimate. The very next day, his team arrived and completed the work — repairing the damaged ceiling, blending and repainting so it matched seamlessly, and leaving the space clean and orderly when they finished. This is the second project they’ve completed for me, and once again the work was professional, timely, and well done. I trust their process and their results. I’ll absolutely be calling them back for future remodeling projects and would confidently recommend them to others."

FAQs for addition to existing structure building service projects in Dunwoody, 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.
