"Greg & his team did a wonderful job on my renovation project, with exceptional marks for honesty and communication. Pricing was fair, and there was always confidence in the work itself: it's clear that Greg brought a tremendous amount of experience to the project, and he consistently ensured that work was done correctly (down to every last detail). I could not ask for a more reliable and honest person to deal with! Additionally, the scope of work changed on our project due to additional requests we had (our decision to re-do walls, install new lights, etc.) yet there was never any worry or concern on unfair pricing. Greg gets five-stars, and we will definitely work together again in the future."

"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."

"Hector and Moises were excellent! Hector came with one other of their crew and assembled my permanent gazebo. I have stone pavers and they were very careful in cutting them and digging Deep enough to establish a good anchor. They even installed railings for my back stoop. I would highly recommend them! Clean... affordable and professional."

"This was a fairly big job to completely remodel our unfinished 1000 sq foot basement. The job took about 5-6 weeks to finish. Jeff showed up every day with his small crew and did an amazing job. Jeff was easy to work with and delivered everything we asked for. We also had Jeff's team replace our den floor with a heated tile floor which came out amazing. In addition, they also resolved a complicated leak that required some detective work to determine where it was coming from and thy were able to find and resolve the issue. I would highly recommend Northgate! Thanks Jeff!"

"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."

"<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 />"

"Bobby and David provided great customer service, high quality work and excellent pricing. For my new kitchen, I had an interior wall removed (they brought in a structural pro to check for safety) , moved plumbing and added electrical. The entire kitchen was gutted and redone. They helped me with all my flooring and cabinet selections- they really know what works best! All my phone calls to them were returned very quickly. I highly recommend them and plan to call them back for more work!"

"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."

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