"Jaime and his crew were wonderful to work with. They stuck to the end of the job until every single item on the check list was done. This I find rare in the construction business. They were courteous and mindful of schedule. I recommend Rea Construction to anyone looking for quality work."

"

This is the 2nd major project I contracted Art DeRosa & Co for.  The 1st being 4 years ago a major living room/family room renovation which was hugely successful.  That 1st experience led me to award Art (after several other competitive quotes) this 2nd and far larger & more complex project.







Overall it went well but this was a complicated project encompassing all the typical trades and expertise of building a new luxury house but far more complicated because it was a renovation performed while we were living in the home. Dust partition walls with wood framing had to be erected in several locations in the house which included temporary doors for entering and egress in certain areas of the remaining living areas of the house in order to protect the remaining house from dust and demolition , as well as, provide privacy for us during construction. 

Experience, Experience, Experience and Professionalism, Professionalism, Professionalism are the hallmarks of Art DeRosa and company.  He is a seasoned performer and pretty much seen it all.  Art has such a vast amount of home construction experience in both hi-end and medium end homes that he can draw upon a wealth of knowledge in all construction disciplines to implement a fine finished result.  As a former tool and die maker his penchant for hi-precision finish work yields highest quality appearances to things like moldings; trim; windows; doors; floors; etc. etc. 

This complex renovation project lasted 7 months which was within the initial time estimate given at the beginning and Art DeRosa and team were here every single day, day in and day out,  bright and early during that time frame. He did not start any other projects and stayed on the job day-in and day-out even when other sub-contractors such as plumbers and electricians were on the job site excluding his people from doing any other work. Art DeRosa and team were here every single day until final signoff.

I would not hesitate to recommend Art DeRosa & Co for any planned New House and/or House Renovation of any kind.

"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 !"

"I used K&A Home Repairs to rebuild my deck. I found them to be dependable, professional and experienced for what I needed. Anthony came at the appointment time to provide a fair estimate and followed the work schedule as close to the plan as He could, weather permitting. I am extremely pleased with my new deck and will be calling K&A for more projects on my home."

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