Asphalt Shingle

Asphalt shingles are the most common type of residential roofing, as they are relatively inexpensive and simple to install. They are composed of asphalt and a reinforcement layer that is coated with mineral granules. Asphalt shingles come in two standard design options: Architectural shingles and 3-Tab shingles. Architectural shingles are generally thicker and stronger and vary in shape and size.
