"Although Cody did a great job on my roof, he then stole $9600.00 from my parents after I referred him to them. He has also stolen money from several other customers over the last year. My parents have been unable to get their money back from him to date. He has also been known to change his business name when customers realize he is taken their money without doing the work. He is a con and his felonious business practices should make anyone leery of hiring him. "

"Jim and crew are reliable and knowledgeable. I agree with all that Dana C in Kensington shared. We hired Jim to close in a carport for an addition by seeing the work he was completing for Dana. I then had him remodel an old garage that needed a face lift. We now have Jim building a ranch home for us from the ground up. It is going just as well. If only the prices due to the economy were not so disappointing. Materials are through the roof as a result. Here hoping for some REAL change in 2025 !!!!"

FAQs for addition to existing structure building service projects in Seabrook, NH

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.
