"We contracted Henry as our GC to lead a 175K addition/renovation of our home. We added a master suite (w/ walk-in closet), another bedroom, a play/rec-room, and a workshop. We also took down the walls of an existing room to open up the common areas and built a hallway of pocket doors. We found him to be a great communicator. His subs were professional and courteous. Highly recommend him for others and would be happy to hire him again for future projects."

We pride ourselves on being a unique construction company. Everything Under the Roof is an interior, residential construction company owned by Kim and Jay Spanier. At work we are a husband and wife team, but at home we are mom and dad, so we truly understand the importance of keeping your project orderly and on time, while keeping your family (including your pets) safe. We can also guarantee NO high pressure sales calls, and no crabby, condescending construction guys working on your home improvement project – just our family helping yours! Kim is your main point of contact through the project. She walks you through the construction process, acts as your personal construction jargon translator, and, most importantly, she is the budget master. Kim will help you shop for materials so that you stay on budget. Jay is the jobsite superintendent. He manages the day to day activities of your remodeling/construction project, he coordinates and manages the sub-contractors, and it’s his skillful carpentry that will transform your home. All of our projects work within the existing footprint of your house. What exactly does that mean? Well, in a nut shell, we don’t do additions, and we won’t raise your roof. We find all the hidden, un-used spaces in your house and re-create your floor plan to work for you and your family.

"My wife and I needed to finish our basement to accommodate our growing kids. We had an excellent experience with Everything Under The Roof. They really listened to what we wanted to build and everything was done well, on-time, and on-budget. One thing I particularly appreciated is that the owner was onsite doing the work, and not simply sending a team of workers. We'll definitely be using Everything Under The Roof for any future projects. "

FAQs for addition to existing structure building service projects in South-britain, CT

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.
