  Was referred by my friend to do do my roof and siding. I was not there to see how they did the roof, but the staff who did the siding work was easy to work with, works hard and fast. It comes out very nice, they really did a great job. Thank you Manny and your team for make us a new house! Because of the look, couple of the neighbors already asked for the contact!

  Manny and his team installed new gutters for our house early 2025. Stellar work, and Manny was very communicative and reliable. New gutters withstood the harsh snow from last season as well. Excellent work overall, and would definitely recommend him and his team.

  I recently hired GN Exteriors to replace a rubber roof, and from the start, the experience was impressive. Manny, the owner, personally came out to give an estimate. He was not only friendly but also very knowledgeable, which immediately gave me confidence in their work. Once hired, the team showed up as promised and completed the job with exceptional attention to detail. As someone who tends to be quite picky and observant, I was pleasantly surprised to find nothing I would have wanted done differently. Every aspect of the roofing replacement was handled with care and professionalism, reflecting a high standard of quality. Overall, I’m very satisfied with GN Exteriors and Manny’s team. If you’re looking for a reliable company that delivers excellent results without cutting corners, I’d definitely recommend them. It’s rare to find a service that leaves you completely worry-free and confident in the outcome, and GN Exteriors managed to do just that
