Great experience with NISI. We needed a new roof and gutters for our house and garage. Nelson never pressured us on his intitial visit. The estimate was better than the ones we previously received. Communication was flawless. The work crew showed up on time and were very professional. They did an excellent job all in one day. They spent much time meticulously cleaning up after the job was done. The yard was spotless when they left The roof looks fabulous. Not one complaint. Very pleased with the whole process and will absolutely recommend them. pete messina2025-03-20 Working with Rey and the NISI Home Improvement team on my siding project was a pleasure. They took their time to review and accurately diagnose the issue with my siding and provided a thorough plan to resolve it. They answered all my questions before starting the project and kept me updated on their progress throughout the work. The team arrived on time, worked diligently, and left my home clean. I am thrilled with the results of my siding project and highly recommend the NISI team for any exterior home improvement needs. I look forward to collaborating with them again.

Leslie Trigos2025-03-16 I happen to be walking my dog when I observed the workers replacing a roof on a house a block from mine. They were efficient, professional and very careful of what they were doing. After reading some reviews, I decided to call them as the local people I had called were not responsive to my needs and thought that I had an open check book. None the less, in the last 4 weeks, they have come to my house twice and replaced my gutters and five (5) windows that needed replacement. When Rey came over to the house initially, his demeanor and personality was spot on as he did not pressure me into anything unnecessary and I felt he was being very fair. Once the job got done, I have NOTHING but praise for his men, they were spot on, the installs were perfect and they cleaned up better than it was before. I would highly recommend this service if you want quality work that is fairly priced and want people in your house that take pride in their work.

Their price was competitive and the workers were clean and respectful. I want to thank them here. Ken Kenneth Kraemer2025-03-10 Professional service. I would recommend. Sal Lopez2025-03-04 Outstanding Roofing Service – Highly Recommend! I recently had the pleasure of working with NISI Home Improvement, owned by Rey Guevara, and I couldn’t be more satisfied with their work. From start to finish, Rey and his team were professional, responsible, and punctual. They delivered exactly as promised, completing the project within the agreed-upon time frame without any delays. One thing that stood out was their attention to detail and cleanliness. At the end of each workday, the crew made sure to clean up thoroughly, leaving no mess behind. This level of care and professionalism is rare and truly appreciated. If you’re looking for a reliable, high-quality roofing company, I highly recommend NISI Roofing. Whether you need a repair or a full roof replacement, Rey and his team will exceed your expectations. I will definitely be using them again for any future roofing needs!
