Ace & his guys were amazing! Has a woman I'm always fearful of hiring contractors, I just feel like I'm gonna get taken advantage of. Not these guys! Very honest and through.  So responsive and just overall amazing service! I would hire them again and again!!

GNS came in and identified a leak point on my roof that several other contractors were not able to fix. Very impressed with the professionalism and attention to detail. Had 6” gutters installed as well for a fair/reasonable price. I will absolutely be using these guys again in the future. Highly recommend!

After months of searching and asking for referrals, we were finally recommended GNS Roofing Corp—and we couldn’t be happier with the experience! From the very first call, they were incredibly responsive, answering all our questions and scheduling a visit within a week. Their team spent a large portion of the day thoroughly cleaning out our gutters, ensuring that nothing was left behind. Our business looked spotless and refreshed when they were done. It’s clear they take pride in their work and customer satisfaction. We highly recommend GNS Roofing Corp to anyone in the Winchester area looking for reliable and professional service. Plus, it’s great to support a trusted local business!

It was a pleasure dealing with GNS Roofing from start to finish. They were very professional, friendly and efficient from the scheduling, the shingle delivery, the management and crew, compleing the job in one day, the clean up, and most importantly, the quality of their work. I was so pleased with their work that I had them replace a shingle and metal roof on another property. I highly recommend GNS Roofing.

We have used GNS for roofing repairs. GNS located and repaired a leak around a vent pipe on our home. We have also had them to repair some wind damage on our detached garage. Their response was quick on both issues. They are reasonably priced and very reliable. They do good work, and we are very satisfied. Recommend. Winchester, VA

GNS Roofing is a 5 star all day.  Performed roof work and installed a wire basket over a vent as we had wildlife living in our walls.  Work was performed timely, as promised, no surprises.  Thanks GNS, you guys rock!!!

They did great job putting new roof on our house.  We got a total of five bids and GNS was most competitive.  Great service at great price.

We had an issue with a leaky roof last winter and called GNS Roofing.  GNS was able to repair the issues to get us through the winter season.  In the summer, when we decided to get a new roof, we called GNS Roofing for an estimate. GNS' service was great.  The owner provided fair pricing and walked us through every step of the project.  He explained the details of how the work would be performed and gave us various options for materials.  He showed us previously completed projects to make sure we understood the differences in the colors and materials.  Every facet of the project was performed professionally, from stocking the job to completing the project to following up with any issues and concerns.  We were so impressed with their service that we decided to contract with them for additional services, including cleaning our siding and gutter replacement.  I highly recommend GNS Roofing.

GNS put on my new roof several years ago, and I couldn't be more pleased.  They did a beautiful job with the original install, and have been extremely responsive regarding my requests for annual inspections, maintenance, leaf removal, etc.  They usually respond within a day of my call.   I would highly recommend them.
