Customers say: Quality work

"Can somebody enjoy and connect with the company of roofing personnel . I doubt. Many finish their work and vanish. What makes Steve & Sons different is the way they understand the needs of the customer. The team excel in meeting with the client ahead and in analyzing all the aspects of the work along with what can and cannot be expected . This gives a better idea of the work schedule and work details involved. They did a great job with our Asphalt shingle roof installation. We appreciate their work and dedication. Steve says he talks a lot , but thatâ s a good quality in this business to communicate things well. Thanks again."

"David from Belinquete immediately understood what we were trying to accomplish and provided thoughtful, thorough recommendations throughout the process. His quote was delivered promptly, and once we accepted it, he quickly scheduled the installation. David and his team completed the work exactly as promised, on time and with great attention to detail. We had high expectations going into the project, and Belinquete exceeded them in every respect. I would not hesitate to hire David and his team again and highly recommend them to anyone seeking quality workmanship and exceptional service."

"Working with Mark was easy and efficient. He talked through what we were looking for in additional space (master bedroom suite) and we worked out all of the small details. We love the old New England look of our home and he was able to capture that look in his plans while giving us the modern updates we were looking for (closets and a large bathroom). He gave us 3 versions of the overall design to choose between. Once we had chosen the design, he produced the building plans. He also coordinated with an engineer to do the engineering report. All the while, he was extremely responsive and reached out whenever he had a question about what we were looking for. I highly recommend working with him!"

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