Customers say: True professional

"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 ? ? ? ? ?"

"Memo and Abby are fantastic. The communication is exceptional in both clarity and attentiveness, and the work quality - from prep to the job itself to clean up - itâ s the tops. I engaged Memo to build/install and paint, finish, and wallpaper a double-sided wall with some mill work and moulding details. For the same room I also engaged him to purchase/hang/install a solid core slab door in an existing doorway. Though not a huge job, as a designer I was really keen to work with someone on the details - and Memo was so easy to do this with and delivered on everything I wanted. I will absolutely be hiring Memo again for more things and bigger jobs."

"cannot recommend this company enough. They very graciously took on my very difficult project after another contractor resigned. I am beyond happy with the result. I know that with this company that the job has been done properly. Robert was able to communicate exactly what was being done, when, and why. The communication was unmatched. I will actually miss their excellent communication, the job was done in a timely manner. More was completed with this company in 2 weeks than 10 months with my previous contractor. Robert was kind and hardworking. I have only positive things to say about Classic Home Design and Construction LLC and I will happily use them again in the future, and I am thankful I was put in touch with such an upstanding company and people behind it."

"I am incredibly thankful to Ray LaManna and Tri Build Construction for my new roof. I had major structural damage to my roof due to improperly installed solar panels. Not only did Tri Build diagnose the leaks before the repair, they fixed it in record time. It was extremely reassuring to know what the cause was and how it would be resolved so that I would not have to worry about my home, my greatest investment. If you have roof damage due to improperly installed solar panels, or if you’re looking for a new roof and need a competent and honest contractor, you need Tri Build Construction, a U.S. Veteran owned company."

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