"I am overwhelmed with the way my projects turned out. I had a patio redone and added a sunroom to the back of my house with a wood deck bringing the two spaces together. The crew was courteous and meticulous with their equipment. I really appreciate how responsive the office and my project manager were every step of the way. I can’t wait to spend an enormous amount of time in my new living space. "

FAQs for addition to existing structure building service projects in Westerville, OH

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.
