"I can’t recommend Stars and Stripes highly enough for anyone considering a home renovation. From big projects like installing new countertops and a backsplash to smaller details like fixing the track on my sliding closet doors, everything was completed with exceptional care and attention to detail. What really sets them apart, though, is the trust factor. I’m not someone who’s usually comfortable leaving people alone in my home—but with Stars and Stripes, I never once had to worry. They were respectful, reliable, and I always felt my home was in good hands. It's rare to find that kind of peace of mind with contractors, and it's what will keep me coming back for future projects."

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

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