"We found REA Pro through positive reviews online. Jaime Rea was one of several contractors we interviewed. He is very prompt, energetic, and an excellent communicator. After an initial phone call and site visit, Jaime provided the estimate within a couple of days. The project – which included renovating 5 decks, repairing siding, and painting the exterior of the house – was started on time and completed within Jaime’s time estimate. His crew was very professional and personable and a pleasure to work with. We were really impressed with the quality of the work and their attention to detail. We are very happy with the final result, and would hire Jaime and his crew again for other projects."

"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."

"Excellent! Alta Renovations did my bathroom from the studs out. Tile, sheetrock, floor, vanity and the plumbing and towel hardware. The job was was in a co-op, with very frustrating "rules" and "requirements ". Most contractors would not want to participate (paperwork, time schedules and parking restrictions). Jose, the owner of Alta, abided by all the rules, whiles still keeping a smile!!! His workers worked neatly and orderly, knew exactly what had to be done, and did it. Very pleased. I'm recommending him to all my ? ? ? ? ?"

"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."

"Premier Home Remodeling was able to walk my family and me through the whole process of remodeling our kitchen and were able to save us time, money, and stress by getting us exactly what we needed at an affordable price. They were a one-stop shop for everything, their cabinet selection is beautiful and their selection of tile was far more diverse than most other showrooms we visited. In addition, they acted as our designer and were able to guide us on the different styles and layouts that would work together to make our kitchen our dream kitchen. I highly recommend this business! - Adam T."

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