"Ben Dill worked with us in turning a garage loft into a functional, fully built-out room with bath. He is a creative craftsman who, with his team, did a beautiful job on the project. He is both easy-going and professional and clearly has a passion for his work. We appreciated his suggestions on many of the myriad details, particularly in relation to materials and finishing touches. He came in on budget and communicated regularly for clarification of plans when necessary. We enthusiastically recommend Ben and his team at Outermost Building & Renovations!"

"We recently had an “old school” original 1970’s Cape Cod kitchen fully remodeled including adding a slider. Richard did a great job from planning and design (shout out to Hanna on this), to demo, to install, to finish work. Richard was on time, reliable, and not your typical Cape contractor. Super clean at all times and was able to work with us on various hiccups/unexpected stuff along the way. He explained options and the pros and cons of each possible choice. He never upcharged us (unless we asked for something) and was exactly on budget. Very happy with his work and would definitely recommend. We will likely call on him again for our next project."

FAQs for addition to existing structure building service projects in Dennis, MA

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.
