I came upon GNS by accident when they were replacing a friend’s roof and am glad I did.  I was pleased with the whole process, including not just a job well done, but also the explanation of what would be done, and what to expect with follow up procedures as well. It was very nice dealing with this local family-owned company, and I would recommend them to others.

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 Update 6/7/26 GNS Roofing has been repairing and maintaining our aging roof for several years. This year we had them replace the roof on our house and detached garage. They also did some vinyl siding repairs for us. They did an excellent job on all of it. Their prices are reasonable and they are very reliable. Very satisfied. I highly recommend GNS Roofing, Definite 5 star.

I found a leak near the exhaust of a B vent on my roof. I had called one other company first that came out and said my six-year-old roof was installed poorly and desperately needed replacement. I then called GNS Roofing and they sent a representative to my house pretty quickly. He identified that the vent was installed incorrectly and they would need to pull up shingles, reinstall the vent, and replace the shingles. GNS Roofing offered to do the repair that same day. He spent about 4 hours total on the repair, and for a very appropriate price I now have a leak-free roof. The dispatcher was very communicative on the phone and the representative that did the repair was very friendly and effective. I hope to never have to call a roofing repair company again, but if I do, I'm calling GNS Roofing.

Over the past year, GNS has helped me with a few roof repairs and eventually a full roof replacement. They were always fair, honest, and upfront with the entire process and all that it entailed. Very reasonably priced for the quality of work. Would highly recommend

Jose and Ace started the job on time and finished ahead of schedule. All the materials they used were top quality. The crew that installed were respective and courteous. The workmanship was excellent.  When finished they cleaned up everything. I would recommend them.

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.

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.
