"We recently completed an attached 2 car garage with finished space above, a large undertaking, and hired Christian with Nighthawk construction. My husband and I Couldn’t be happier with the results. His communication was top notch, always responding to our calls and texts quickly and keeping us in the loop and up to date with plans and progress. He was knowledgeable, professional, and an all around nice guy. He was able to troubleshoot effectively and helped us navigate the home renovation process. We really enjoyed working with him and are thrilled with the final results. The addition looks fantastic and he was able to do it all within our budget. We have recommended him to everyone and won’t hesitate to use him for any future projects."

"BJ built a beautiful, durable deck. Him and his crew were very professional and the communication was top notch. This was definitely a tricky project as some of the other contractors that came to give quotes did not even know where to begin or just did not want to attempt the project all together. I made some changes to my end goal during construction and BJ was extremely accommodating and understanding. Will definitely be hiring him again."

"I cannot say enough great things. Top-notch communication, speedy responses. Arrived on time. With the whole lawn being seeded, weeks later half of the lawn was not growing, while the other half was clearly doing well so they came out (as promised and on time) and assessed the situation and decided to add more seed to the bare part of the lawn - free of charge. They also left the little bit of leftover seed. They wanted to make it right. Would definitely hire again in a heartbeat."

FAQs for addition to existing structure building service projects in Oswego, NY

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.
