    We couldn’t be happier with our experience with Long Island Roofing and Siding! From start to finish, everything went exactly according to plan. Chris, Russ, Bobby, and Edgar, along with the entire crew, were an absolute pleasure to work with — professional, friendly, and truly skilled at what they do. Their craftsmanship and attention to detail are outstanding. Every part of the job was done with precision and care, and the results speak for themselves. The team showed up right on schedule each day and completed the entire project in just four days, exactly as promised. Any small issues that came up were resolved within minutes — no delays, no hassle, just great communication and teamwork. It’s rare to find such a dependable, detail-oriented crew that also takes pride in their work. I highly recommend Long Island Roofing and Siding for anyone looking for top-quality workmanship and a smooth, stress-free experience!

    We recently had our entire roof and siding replaced by Long Island roofing and siding, and the experience exceeded all expectations. We are incredibly grateful for the high quality of work and the outstanding professionalism displayed by the entire team. From start to finish, the crew was meticulous, efficient, and clearly took immense pride in their craftsmanship. The finished result is stunning—not only does our home look beautiful, but we are confident in the durability and protection provided by the new materials. They ensured the worksite was cleaned up perfectly every evening, leaving no trace of debris. What truly set this experience apart was the exceptional communication and responsiveness. We want to specifically commend Chris and Russ who were our main points of contact. No matter how small the request or how many questions we had about the process or materials, they were always quick to respond, thorough in their explanations, and genuinely patient. It felt like we had a true partner managing this large project, not just a contractor. If you are looking for a roofing and siding company that delivers top-tier quality combined with world-class customer service, we wholeheartedly recommend them. Thank you, Chris and Russ, for making this a smooth and stress-free project

    Russ, Chris and the entire crew did an incredible job from start to finish on my roof! They were extremely competitively priced, gave the best warranty out of all 6 quotes I received and communication from my first phone call to handing over payment was seamless. I only have good things to say about these guys and I’ll be the first one to say I’m not easy to work for! 5 Stars all across the board!!! (I’ll post pics when siding and windows are all complete)

    What can I say Long Island Roofing and Siding was phenomenal! I couldn't be happier with the results of my roof and siding replacement! From start to finish, the team was professional, efficient, and detail-oriented. Honestly I can’t say enough good things about Chris and Russel! Chris came to my house twice to make sure I was comfortable with the roof and siding I selected not to mention he explained GAF’s Warrantees and the installation in a way that I understood. Then when the work began Russel was on site for both days and was amazing and answering questions and explained everything every step of the way. Russel addressed all concerns I had. The crew worked efficiently and cleaned up thoroughly after the job. I would also like to give a special thank you to Bobby for his hard work during this process. If you're looking for high-quality work and excellent customer service, I highly recommend this company. Thank you for transforming my home, I love it!
