"Jeff did a great job with our projects. He completed each project with experience, knowledge, and attention to detail. He installed hardwood floors, tiled our master bathroom, removed wallpaper, and painted the interior of our house. The tiling and hardwood install were precise, with no margin for error. The painting looks great. We would definitely hire Jeff again!"

"Bruce is always honest and very fairly priced. Stays true with the estamint I hired him for tree felling and 2 new deck builds on the front and back of my house. I couldn't imagine having another carpenter do work on my house. He makes himself available and keeps you updated on what ever project he's doing. 100% recommend BMC Builders! You won't be disappointed!"

"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."

"Went smooth as it could, the building was built in 1835 so there was some apprehension about the doors but overall it went super smooth. They showed up when they said they would be there, strategically coordinated around my tenants schedules and did a beautiful job. Will def hire again."

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