"I hired Kevin Martin (H. Hedges Home Improvement) to build a new deck, replace a bathroom floor, and repair kitchen cabinetry. Kevin's quote was very competitive and fair. He and his crew showed up exactly when they said they would. He was very collaborative and his communication throughout the project was excellent. It is clear that he wants his customers to be happy at the end of the day. Our HOA also hired Kevin to replace fencing for a 14 unit association and build a new enclosure for a dumpster. Again, his bids were fair and competitive and he performed quality work. I would not hesitate to recommend him."

"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."

"Asa again was easy to work with. He is professional and honest in his recommendations and was fine if I wanted to go in different direction as long as it maintained the quality of the work. I almost always went with his recommendations though. Other tradesmen have commented on the high quality of his work which meant that potential renters were willing to pay more to live in such a great place!"

"It went great. Chris built our custom home exactly to our specifications. We lived out of state for the entire build. Chris maintained open lines of communication with us so that we always knew what was going on. His work is impeccable. His attention to detail resulted in our dream home being exactly what we expected when we hired him. His group of subcontractors were great throughout the entire process. I have not spoken to anyone in the area that has anything but praise for Chris and his work ethic. Chris came highly recommended by a number of people and I would carry on that tradition and recommend Chris Johnson for any construction project from a remodel to building a new home from the ground up. I would certainly use Chris again for any future construction needs."

"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, the owner of Magic Frog Carpentry & Woodworks is great to work with. He is responsive via text and phone conversations. He has a lot of skilled people he works with and does a lot of the work as well. When any hiccup comes up he is quick to get it resolved. This past fall I hired him to do a partial remodel of my kitchen (new countertop, new backsplash, new flooring and painting. I was happy with the work and decided to hire Adam again for a tub to shower conversion. I am really happy with the results of both projects. I plan on reaching out to Adam for the next home project."

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.
