"This contractor is an absolute gem! The project entailed a complete gut of a galley kitchen, an expansion of a first floor bathroom, and renovation of first floor upper and lower foyer floors and walls. All work areas were in original condition from 1972. The owner was on site every day. His workers were knowledgeable, clean, respectful, and professional in every sense of the word. When problems with the original construction of the house were revealed, Ray (the owner) offered solutions as to how to overcome them, providing options and opinions. As with any major renovation, there were only a couple of items that needed to be addressed. Ray and his crew came back even after being fully paid and corrected the defect with no additional cost to us. His price was fair for the amount of work he performed and the kitchen, floors, and foyers look spectacular! It's tough to find a contractor with ethics and integrity, but Ray Lamanna and Tri-Build Construction are certainly in that category. We certainly will be using them again for our next project."

"I hired Long Island handyman construction group to remodel a 400sf basement and bathroom in Melville. They were priced in the middle compared to other bids. I picked them thanks to their out of the box advice which saved me thousands of dollars. There was one problem with the plumbing which cost an extra 1800 dollars. The owner settled with me 50/50 even though it was a pre-existing issue. The project was started early and completed early. All mess was cleaned up and the crew was very friendly and fully aware. Very reputable guys and very easy to deal with. Thanks Moises and Eddy."

"I was very satisfied with the job and Jeff and his workers were very courteous and professional. They showed up when they said they would. While they were working on the bathroom, I added some additional work and they accommodated me. They replaced the sheetrock on part of the wall going downstairs to basement and installed a banister. I will definitely use Jeff in the future and recommend him to others."

"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."

Customers say: Quick response

"<p>This is the 2nd major project I contracted Art DeRosa & Co for.  The 1st being 4 years ago a major living room/family room renovation which was hugely successful.  That 1st experience led me to award Art (after several other competitive quotes) this 2nd and far larger & more complex project.<br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /></p> <p>Overall it went well but this was a complicated project encompassing all the typical trades and expertise of building a new luxury house but far more complicated because it was a renovation performed while we were living in the home. Dust partition walls with wood framing had to be erected in several locations in the house which included temporary doors for entering and egress in certain areas of the remaining living areas of the house in order to protect the remaining house from dust and demolition , as well as, provide privacy for us during construction. </p> <p>Experience, Experience, Experience and Professionalism, Professionalism, Professionalism are the hallmarks of Art DeRosa and company.  He is a seasoned performer and pretty much seen it all.  Art has such a vast amount of home construction experience in both hi-end and medium end homes that he can draw upon a wealth of knowledge in all construction disciplines to implement a fine finished result.  As a former tool and die maker his penchant for hi-precision finish work yields highest quality appearances to things like moldings; trim; windows; doors; floors; etc. etc. </p> <p>This complex renovation project lasted 7 months which was within the initial time estimate given at the beginning and Art DeRosa and team were here every single day, day in and day out,  bright and early during that time frame. He did not start any other projects and stayed on the job day-in and day-out even when other sub-contractors such as plumbers and electricians were on the job site excluding his people from doing any other work. Art DeRosa and team were here every single day until final signoff.</p> <p>I would not hesitate to recommend Art DeRosa & Co for any planned New House and/or House Renovation of any kind.</p> <br />"

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