"TKT Remodeling Group LLC is professional, fast & responsive, and very skilled in their work. They did an incredible job replacing our asbestos tiles in the boiler room, leveling out the floor, and adding tiles. They also installed an excellent fire proof door for the room, and fixed our dryer vent so that it was up to code. Additionally, they installed 4 mini splits in the house. They were very diligent in their work and quality control. After the installation they tested all the units and found out one was malfunctioning. They immediately called the supplier to help us get a new replacement unit, advocating on our behalf and pushing back against the supplier's suggestion of simply replacing a part in the malfunctioning unit, and had it replaced in one day. They go above and beyond in all aspects of their work and are very pleasant to work with. We are incredibly satisfied with their fast, and efficient work and highly recommend their services. We'll definitely be using them in the future for any home projects!"

"Mr. Powers, at first, was courteous and reliable; the project seemed to have problems, and he was getting frustrated at having to surface the existing deck due to its configuration; he claimed that the measurements and figures were off, while another professional disagreed with his calculations; the project was delayed due to materials being delayed by supplier; Mr. Powers suggested another other remedies for steps and that I purchase an additional type of board for $120, which I did; i paid Mr. Powers in full of the understanding that he would come back and finish off certain areas; during this time, a death occurred and he was unable to come when scheduled; when I texted Mr. Powers, he began belligerent, and cursed at me. I do not find it professional to curse at a client and refuse to take phone calls. I ultimately told Mr. Powers not to come back to my house and to refund the board I purchased that was in his possession. He did so. Since the time of completion, May 2026, numerous boards have come loose. I had someone else correct this issue, and now more boards are coming loose, which I texted him about and showed pictures of on September 9, 2026, and have not heard back from Mr. Powers regarding acknowledgment or addressing the loose boards, as my contract provides for two (2) years."

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