"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."

"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."

"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."

"The construction company, MGT Construction has just completed our +/-600 sq foot deck at our home in Southold. MGT managed the planning: We were determined to build the deck per Southold Town code using Timber-Tech composite decking and railings per their specifications. After we had the survey done Steven coordinated with their architect and liaised all building inspections. He was instrumental in all follow-ups with the town until final approval of the permit. We sourced the pressure-treated framing lumber from Amagansett Lumber and with four feet deep footings the underlying structure is solid and constructed to last 30 years, which is also the guaranteed life of the decking. MGT Construction excels in the carpentry aspect of the decking. They made sure the planks were correctly aligned and the surrounding picture frame planks were precisely fitted. This was also true as well regarding the fitting of the railings. We opted for “drink rails” and their finishing on those is superb. Our overall impression of the construction staff was that they were always courteous and friendly. We did however make the observation that the workers should pay attention to their attire, which at times was needlessly sloppy and awkward. However, they were hard workers and respectful. An electrical subcontractor had to redo work because a supervisor was not on the site. The work was corrected and promptly made without complaint. Cleanup was done in a timely manner and to our satisfaction. Having had other construction work done on homes I can honestly say, MGT Carpentry was professional and their work was excellent. I highly recommend them."

"The installers arrived on time, were immaculate and the tile job was perfect. The slab was uneven but they somehow managed to pit in a perfectly level floor. The employees are very pleasant and professional. They came highly recommended by Cancos Tile, which is how I found them."

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