"Because we were going away for an extended time, and insulation work by others had to be completed first, we had to schedule drywall workday NH Projects under a rather tight time frame. Despite uncooperative weather (lots of rain slowing the drying time), they managed to get everything done as needed, working around other scheduled work they had. They were prompt, professional, and a pleasure to interact with, in addition to doing excellent work."

"Chris was able to put double closets in our bedroom. They now look like they have always been there. The work was done quickly quietly and efficiently. Pricing was very reasonable and the finish quality was excellent. I’ve seen other examples of his work and it’s well designed and definitely top quality. Happy to have worked with him."

"Nice family business. Had some trouble with some employees getting started but Costas and his dad always took over and made sure everything was great. They did most of the work themselves which was important to me that someone was always on site. My schedule is crazy. Iâ m often not home and I trusted them to be here and get the job done without my oversight. We ran into some challenges, even added a few more jobs to the project. He took in stride, eager for the work and honest and upfront about what he could do what needed to be done? I enjoyed working with him, so Iâ m giving him another project"

"Adam did an excellent job building our garage from the ground up. He was excellent to work with. Not only was he very professional, so were the subcontractors that he hired. Everyone was knowledgeable, helpful and friendly. Our project required that a road be built to accommodate large trucks in the springtime. The project stayed on track and proceeded smoothly. We were never left wondering “what’s next?” Adam has great communication and stayed in touch to make sure we knew what was coming up and when. I would definitely recommend using Magic Frog Carpentry."

"When you find a great contractor, don’t let them go. ;). I hired Tim to build a screen porch under my deck but added several projects as I recognized the high quality of work and attention to detail from his crew. In addition to the screen porch, they built a deck extension - so nice that I decided to have them replace the existing deck, installed a basement slider and replaced the door, installed a new fence and built a shed. Tim was responsive, open, honest and receptive of my requests and additions during the project. Great experience working with Tim and his crew: Dan, Brian, Eddie and Ben. Great job on all the work - I’ve received many compliments from neighbors and guests on the work you did! I can’t recommend Tim and his crew enough."

FAQs for addition to existing structure building service projects in Rochester, 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.
