Working with Scott restored my faith in the existence of professionals out there who are committed to delvereing results with impeccable work ethics, attention to details and care for client satisfaction. I will go back to Scott for future work as I have watched him priotrise my happiness with everything from the quality of paint to the smallest issues with the new floors we got."

"Anthony and his crew were friendly and professional throughout the whole project. Anthony gave us a clearly broken down estimate prior to starting the work and we were very confident in his work from start to finish. He and his crew did an excellent job and we would absolutely use him again for future projects. His prices were reasonable and comparable to other quotes we received-he provided us with a clear payment schedule over the course of the project, communicated with us every step of the way and went above and beyond to give us tips and additional info that was helpful to us as new-ish homeowners. Would absolutely recommend."

"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."

"We purchased a new construction home in Hicksville built by Sun Luxury Homes, and the quality is simply unmatched. A close friend bought a new build from another builder around the same time, and the difference is night and day. From the craftsmanship to the materials, everything in our Sun Lux home feels solid, high-end, and built to last. Ace and his team don?t cut corners ? the finishes, layout, and overall attention to detail are far superior to anything we?ve seen locally. Sun Luxury Homes has no real competition. If you want true quality and value, this is the builder to trust."

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