"Everything went well. Yamin was very responsive. He always texted when they were on their way. The workers worked well and cleaned up after they were done everyday. They power washed the concrete, exterior of the house and deck. The exterior aluminum siding of the house was then painted and deck stained. We also had our railings scraped and repainted. In addition, they fixed some loose pointing on the chimney and a little masonary work on the front of the house. Yamin was very polite and professional, always willing to work with you. His prices also seemed to be fair."

FAQs for addition to existing structure building service projects in South Richmond Hill, 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.
