Call us Today!!! With over 100 years of combined experience D & R Construction offers a wide range of residential and commercial services. Our focus is on client satisfaction and providing high quality work at a fair and affordable price. Many construction companies have a set hierarchy where owners, project managers, and employees each fall within their respective category. Here at D&R we challenge that hierarchy set up. The owner gets just as dirty as the laborer, and the carpenter gets to know the client just as well as the owner. At D&R we all work together to be the BEST decision a homeowner ever made! We look forward to earning your business.

"In 2021, I hired Eric to fix a water leak in my basement. I paid approximately $8000. Three months after the work was done, there was leaking again. He came over and told me that this was a different leak. After I saved up enough money, I was referred to an expert in basement leaks/foundations. He came over and completed the work. When he was doing the work, he proactively asked me who did the work previously. He said he was clearly not done by someone with knowledge of foundations. I have tried to resolve with Eric. At a minimum, I deserve a refund"

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