"Matt is fantastic! I hired him to do some carpentry work. I know nothing about such things, and he made sure to explain everything—what he recommended, different things he could do, why he was doing certain things—and he included me in every step of the process. In addition, he is very responsive and communicates really well and PROMPTLY! He takes his work seriously, and it shows. I’ll definitely be hiring him again, and I highly recommend him!"

FAQs for addition to existing structure building service projects in Washington, MO

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.
