"I used K&A Home Repairs to rebuild my deck. I found them to be dependable, professional and experienced for what I needed. Anthony came at the appointment time to provide a fair estimate and followed the work schedule as close to the plan as He could, weather permitting. I am extremely pleased with my new deck and will be calling K&A for more projects on my home."

"Artie & Mike are simply the best. I used them to: 1) Build a LARGE extension to my house and redo my entire kitchen and dining room. The job was completed on time and on budget. Throughout the process Artie was transparent & professional. EVERY person who has stepped into my house has complimented at the detailed perfection. 3) Artie built us a custom walk in pantry 2) Built 2 large decks in the backyard as well as an outdoor shower. This project was completed on time, on budget while exceeding all expectations. If you are looking for a contractor and crew that is responsible, responsive, polite, creative and delivers the HIGHEST LEVEL of quality - Artie is the one."

"Jose and his crew did an outstanding job on our extensive interior and exterior renovation, which included a new addition. The project covered everything from a new structural roof with shingles and skylights to new construction windows and doors, siding, a Trex deck, and fully renovated kitchen, bathroom, and laundry room. They also refinished a bedroom and installed beautiful hardwood floors. As with any large project, a few unexpected challenges came up, but Jose handled them with professionalism and kept everything moving forward smoothly. His craftsmanship is excellent, and he’s not only easy to work with but also patient and highly skilled at problem-solving. I wouldn’t hesitate to hire Jose again for future projects and highly recommend him to anyone looking for quality work and a reliable contractor."

"From beginning to end the process was flawless Let’s just start by saying not only was communication and follow up excellent, but unlike a number of contractors, Coco s team shows up punctually and on schedule. The work is priced fairly and done with skill and precision. My neighbors inquired about work on their home after seeing this company in operation. All work was explained and progress updates were provided. I’m totally pleased and would not hesitate to recommend them to anyone, and I have, and will continue to recommend them and utilize their craftsmen going forward"

"I had a new porch built and working with Ken and co, and they were outstanding from start to finish. The crew showed up when they said they would, kept the workspace clean, and treated my home with real care. They walked me through choices, gave clear timelines, and delivered exactly what they promised. The craftsmanship is solid and the porch has already become our favorite spot at the house. What stood out most was how easy they made the whole process. No surprises, no pressure, just steady communication and thoughtful work. I’d recommend them without hesitation to anyone looking for reliable, high-quality construction."

FAQs for addition to existing structure building service projects in Bellport, NY

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.
