I choose Best Roofing of Virginia because they used GAF certified products and installers. I figured, I would get the best value for my money in workmanship along with a warranty. Don explained everything and provided samples and displays of GAF products. They did a great job in a timely matter which only took a day. Price was just right. Being a veteran, I also recieved a discount. Thank you Don and Best Roofing for a job well done.
