"We needed a skylight installed in our bathroom, and MMP did an excellent job--we are very happy with it! The team was friendly and worked quickly and efficiently to get it done before it got dark, and the quality of their work was excellent. Matt was very friendly and nice to communicate with as well, and always responded right away. I highly recommend MMP Construction to anyone looking for great quality work and excellent customer service."

"Can't speak highly enough of Paul and Jay and the job they did for us. It started out as just adding windows to the screened in porch and some insulation and walls in the space underneath to adding a roof over the small sun room on the side of the house to stop the waterfall coming through! Paul was very quick to respond to messages and no changes ever phased him. A complete pro from start to finish. The people he recommended for the electrical were top-notch as well. We have just moved back to the States from overseas and have never lived in this area so he became our go to guy with questions on services in the area and he never led us astray! We have more projects that we will be doing in the future and he will be the one to do them. "

"Corey and his team are great to work with. He is a prompt communicator and is very organized. He also has a great attention to detail and ensures the project is perfect before claiming he is done. He is easy to work with and was able to make our ideas a reality. We have used him for several projects already and have him lined up for another. I highly recommend St. James Construction."

"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 New Boston, 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.
