"Artie & Mike are simply the best. I used them to: 1) Build a LARGE extension to my house and redo my entire kitchen and dining room. The job was completed on time and on budget. Throughout the process Artie was transparent & professional. EVERY person who has stepped into my house has complimented at the detailed perfection. 3) Artie built us a custom walk in pantry 2) Built 2 large decks in the backyard as well as an outdoor shower. This project was completed on time, on budget while exceeding all expectations. If you are looking for a contractor and crew that is responsible, responsive, polite, creative and delivers the HIGHEST LEVEL of quality - Artie is the one."

"My husband and I are so happy with our new deck. Just in time for the beautiful weather! We have Jose Diaz with Alta renovations corp. to thank for making our home improvement job stress free. He and his crew were extremely prompt, meticulous, courteous and great communicators. Jose made me feel comfortable asking questions and was prompt to respond. It was truly an absolute pleasure working with them from the start to the finish !"

"From beginning to end the process was flawless Let’s just start by saying not only was communication and follow up excellent, but unlike a number of contractors, Coco s team shows up punctually and on schedule. The work is priced fairly and done with skill and precision. My neighbors inquired about work on their home after seeing this company in operation. All work was explained and progress updates were provided. I’m totally pleased and would not hesitate to recommend them to anyone, and I have, and will continue to recommend them and utilize their craftsmen going forward"

"Excellent job. Showed up on time and did a nice clean up after. This job was to replace a hole in the ceiling with sheetrock and painting. Very good work; I can't even see where he patched it, so smooth. I will definitely use James Agate Contracting again."

"Ronald and his team were great. He was the first to give me an estimate and was the only one who went on the roof to inspect it. He gave me an amazing price snd was available if I had questions. His team came early (7am) and worked until the afternoon. I would recommend them to anyone and hope to use them again for more work on my home."

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