"The entire team at Ohio Exteriors was amazing to work with. The owner and lead field tech communicated with us all along the way and was very patient with our questions. I was particularly impressed with their attention to detail and the care taken to make sure that we were satisfied. The team promptly took care of any issue that we made them aware of. They were also very gracious about taking care of an issue that was actually our fault. It is evident that Ohio Exteriors cares about the satisfaction of their customers. This is the second time we have used them and look forward to working with them again in the future."

"We had the pleasure of working with River Mill Construction for our Screened Porch project. We had originally worked with Matt back in 2019, and finally in the Spring of 2025 were able to begin the project. Every step of the way was very well executed. The initial plans were clear, concise and accurate. During the construction phase we got to know our builders Mike and Tom, who are absolute rock stars and know exactly what they are doing. We built a very large screened porch with some tricky roof integrations which required the utmost skill and confidence. Everything was done exceeding our expectations and we loved working with the team at River Mill. The build team was incredibly conscientious while working around our home, they would spend extra time sealing off the work areas to limit dust and debris, cleaned up their workspace daily, and were "Meticulous" about their craft. I felt as though they put the same care and effort as if they were working on their own home. They were very flexible and willing to make and discuss any design changes needed. I would highly recommend them for your custom screened porch project!"

"Tim did a superb job of tearing out the old, putting in the new and repairing the active wet spots in the kitchen ceiling. I feel that his estimates were fair and reasonable and the craftsmanship was a world of difference from the previous subpar job I had done. He is very timely, works consistently and stays on schedule. I can't say enough how happy I am with his end result on this project! I'll be having him back to do another bathroom soon!"

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