Darius Sharpe

Cobex did an absolutely fantastic job with my home! They took a nightmare and made it into a dream-come-true. My roof was falling apart, I had dry-rot in multiple areas of my siding and even in the studs. These guys came and worked hard every single day, communicated well, and made my home into what I've always wanted it to be. I would give them 100 stars if I could!

We first had Cobex do our gutters last October. They had the size and the color we wanted. Their staff was friendly and did a beautiful job. We were so happy with the gutters that we had them come back and do our roof. We went with the Owen's Corning Duration Cool with the 50 year warranty. Yeah, the roof will out live us , but the extras that came with it were worth it. Once again their staff was professional and hard working. They were able to take the old roof off and replace it in 4 days. Thank you Cobex!

I hired Cobex Roofing to replace my roof on my manufactured home. My point person was Junior. He was awesome and professional. Extremely friendly and attentive. The crews were unbelievably fast, professional, courteous, and friendly. They worked consistently and steady and got my complete roof done in two days. I highly recommend Cobex Roofing. Ask for Junior! Oh and I live in Rural Sanger area and it's hard to find people willing to come out this far. Junior and Cobex Roofing didn't even hesitate. They set a date and were at my house promptly at 8am! I wish they did more than roofing because these guys are so great!
