Asphalt roof shingles are the most popular roofing choice in America. They are designed to be durable and affordable, and they are available in hundreds of colors and styles to match almost any exterior. There are three major categories of asphalt roofing shingle products available today – strip shingles, dimensional shingles and luxury shingles. It is important to understand the differences between each type of roofing shingle to pick the right product for your home.
