"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."

"contacted Gus for recent roof leak; he was here the same day. He first went into attic space (while there he replaced a burned-out light bulb) to check location of leak, took photos, had me view them; then went on the roof. He located popped nails, which he removed and sealed. Took photo of that as well as surrounding area which he also sealed with a product called, through the roof. He came down and told me the roof vent required a cap and said he would return to install it. Once he installed cap, he also took the opportunity to blow the leaves from the gutter. Once on the ground, he proceeded to blow leaves and debris from front and back walkways."

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