"I hired Jesse's company to repair violations in the building code. Jesse's employee was very punctual, professional and a very skilled tradesman. I noticed during the project that they took pride in their work, and always went the extra step to absolutely do everything right. This experience renewed my faith in some contractors. Anything and Everything will be my only phone call for any work around the house. Even his sub contractors were a reflection of his company. Talented and professional with competitive pricing."

"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."

"I recently had my shingle roof replaced and I?m very happy with the results. The team was professional, punctual, and completed the job efficiently. The quality of the work is excellent, and the new roof looks great. They kept the work area clean and communicated well throughout the process. I would definitely recommend them to anyone needing a roof replacement."

"In summary I have to say Richard was  excellent!  He came when he said he would and finished the work when he said it would be finished.  As I solicited multiple bids for the work NE Renovations was among the most competitive.  As the work was completed I was so pleased I ended requesting he come back to do additional jobs.  He was very accomadating and even explained various options on how best to accomplish the additional work.

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