"Finding a builder who can take your idea (aka Dream) and make it a reality is not easy. Norman Builders created a house for me that exceeded my expectations. Ryan Norman provided me direction before the existing house demolition started. He connected me with others needed for pre-build items. Norman Builders then built exactly what was designed on paper. What sets Norman Builders apart from others is their communication and commitment to understanding what the customer wants. Ryan and his assistant Collin were always available and communicated at every milestone along the way. There was never a time I did not know what was going on or what I needed to decide. The contractors they use are highly professional and care about their part of the build. I love my new house! I highly recommend them and appreciate all Ryan and his team did for me."

"Sean and his crew are truly Professionals within this Industry. Courteous, Friendly, Responsive and produce Excellent Quality Workmanship. By far, Sean and his crew are the best I have ever had the opportunity to hire for a major construction project that resulted in a comfort level knowing that everything was being handled properly. Construction is a challenging venture when putting on an Addition to an existing dwelling. There are many obstacles and challenges that can be faced throughout the project and within the home. Sean and his Team went over and above and addressed each challenge professionally and with timely resolution. I couldn't ask for any better service and results! The addition came out beautiful, I have an awesome Garage and my Wife is ecstatic with her new Mud Room and Pantry! I would recommend Hand and Some for any project that you may need."

FAQs for addition to existing structure building service projects in Newton-Junction, 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.
