"The initial build went reasonably well. We did find problems which they did come back and fix. I noticed a railing support that was cracked. I was told that I must of done it, that was that. The plugs that cover the screw holes in the stairs are falling out. I looked for some at Home Depot, but couldn't find the right color. I still had Chase's cell #, so I texted him and asked if he could send me some plugs, and I would do it myself. No response. Tried again the next day, still no response. I'm not surprised. Aging the build was decent, price was higher than most. Now that nearly 2 years have gone by, and customer service should be anticipated, nothing. Never again."

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