"The work went exceptionally well. The work was professionally done and completed within the original estimates for time, cost and schedule. The work included repairing of plaster, painting of walls, floors and ceilings. Also a problem with existing shingles on the roof was repaired. Several good suggestions were made and used as to the materials to be used and how to best perform the work."

"Exactly what I was looking for, when I hired this company: they “delivered” a good quality product! They were fast, serious and did not overcharge. Yes! I would definitely ask for their service again and absolutely I would recomend them to my friends and family."

Customers say: Super punctual

"Excellent - Tito was extremely responsive and his team did excellent work. I shopped around and got multiple quotes, and his was the lowest. More importantly, he had done work on a number of my neighbors’ homes and came highly recommended. His team was very responsive and got the work done on a short time frame which was great because I needed much of the work done before I moved in to my new home. My floors and skylights look great and I have full confidence in his work. One thing which I really liked is the fact that he is constantly in communication, is always available, and is local. The last part is important because he understands the importance of reputation which gives me full confidence in his work. I will definitely be coming back to him again for any future work on my house and wholeheartedly recommend!"

FAQs for addition to existing structure building service projects in Riverside, CT

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.
