Our services are customized to the individual project, paying close attention to the details of each project that we're involved with. We pride ourselves on the quality of our work as well as our commitment to outstanding results. We look forward to building lasting relationships and guaranteeing your satisfaction!

"My project was small compared to many other projects out there. And yet Josh and Straight Line Constitution were happy to take my business and made it a priority. There was some urgency to getting it done and they sent the right number of people to meet the deadline. And when unforeseeable complications arose they worked with me in order to find a solution that would achieve the goal of the project without extreme cost overrun. There are many contractors out there who will give you a wide range of quotes. If you want to go cheap then find someone who will do a half ass job for little money. But if you want it done right and you want it to last call Straight Line Constitution. The rates are reasonable the quality is top-notch and they're very friendly people to work with."

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