Composite shingles, also known as asphalt shingles, are one of the most popular types of roofing materials used in residential and commercial construction. They are made up of several layers that work together to provide durability, weather resistance, and aesthetic appeal.

The basic design of composite shingles typically includes the following layers:

  1. Asphalt: This is the base layer of the shingle, made up of a tar base that stabilizes and forms the undercoating of the shingle

  2. Mat: This is the second layer of the shingle and is made up of a fiberglass or organic material. The mat provides strength and stability to the shingle.

  3. Asphalt: This layer provides waterproofing and adhesion to the shingle. The asphalt is typically a petroleum-based product that is applied to the mat and acts as a glue to hold the shingle together.

  4. Granules: The granules are the outermost layer of the shingle and provide protection from the sun, wind, and rain. They also add color and texture to the shingle. The granules are typically made from ceramic-coated mineral granules that are embedded in the asphalt layer.

The composite shingle design can vary depending on the manufacturer and specific product line. Some shingles may have additional layers or features such as an adhesive strip for easier installation or additional layers of asphalt for increased durability. Overall, composite shingles are designed to provide a long-lasting and low-maintenance roofing option for homeowners and businesses.

Architectural shingles are practically built up from two layers of 3-tab shingles with the top layer cut out to create the dimensional tab design. These are more durable to higher winds and less likely to breakdown over the course of time if installed properly.
