"We had a very small roof area need to be repaired. I sent request to multiple company to give a service quote. Few of them sent me replies and stated that they are too busy to come. Matt of MMP Consturction's contacted me promptly, scheduled an on-site visit and gave us a quote right away. The work was then scheduled and finished quickly. Matt did great job on reaching out, effective communication, and always arriving on-time. He also gave an evaluation on our roof condition. Also, Eric and Don did excellent job on finishing the project. They are all very polite, knowledgeable, and showed their professionalism. We would like to express our sincere appreciation to Matt and his crew. We are very grateful for having them arriving on-time before the winter storm to prevent potential damage of the house. From their react, we see a warm heart. No job is big or small, all jobs are equally important. Understanding the difficulties of others, for the people, been appreciated by the people. Thank you again for your high quality service. We definitively recommend MMP Construction Inc. to anyone for any related home project."

"Highly recommended. Jose and Cesar were great. They were reliable and their work was excellent. They completely remodeled our condo including 4 bathrooms, floors, fireplace/hearth, etc. It was a big job and they worked with us to make sure everything came out exactly the way we wanted. The cost was very reasonable."

"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."

"This is the 2nd job we has Steve do for us. The was a min bathroom renovation and also kitchen backsplash. Bathroom came out great. He walled off a second door to access the bathroom, ripped out old tile, and put down new tile and installed a new vanity. Very happy with the finished product. Steve also did the backsplash in the kitchen. It came out perfect. I would definitely recommend Steve for any home improvement projects you may have."

"Highly recommended and I will hire again for future projects. Peter was great to work with from start to finish. My project was to remove an existing deck and screen room, repair water damage caused by the old structure, and build a replacement composite deck with screen room beneath. He was punctual, polite, offered ideas, and very clean. My driveway and screen room are probably cleaner now than when he first arrived. As the project was worked on he didn't hesitate to ask for my preference on things that would pop up. He planned his time well, even unexpectingly working in the rain to try to stay on his planned schedule. Price was great for the quality of work."

"Edison and his crew were terrific and we couldn't be happier with the results. He was professional, responsive and even when they encountered some challenges with the gradation of the ground itself to install our fence they came up with a creative solution. I would reccomend Edison and his company for your home project and we plan on using him in the future for others. Thanks Edison!"

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