Asphalt Shingles Asphalt shingles are categorized in different ways depending on their reinforcements and shapes. Asphalt shingles that use organic reinforcing mats are referred to as "organic-reinforced asphalt shingles," and those that use glass fiber reinforcing mats are referred to as "glass fiber-reinforced asphalt shingles. The shapes or styles of asphalt shingles are identified as follows:
Strip Shingles - These shingles are in a strip form and are the most common type of asphalt shingles produced. They generally are longer in width than in height. Common dimensions for standard shingles are 12 inches by 36 inches Products referred to as "3-tab", "4-tab", "random tab" and "no-cut out" shingles are all categorized as strip shingles. Most strip shingles are "self-sealing," that is, they contain adhesive seal strips that bond to overlying or underlying courses of shingles for increased wind resistance.
Laminated Strip Shingles - Sometimes called "dimensional" or "architectural" shingles, these shingles have additional material laminated to strips to create random thickness thereby giving the shingles a more dimensional look. Most laminated shingles are "self-sealing," that is, they contain adhesive seal strips that bond to overlying or underlying courses of shingles for increased wind resistance. Dimensions and weights can vary depending on the manufacturer, and some newer products are available in larger dimensions than traditional standard-or metric-sized asphalt strip shingles.
Individual Shingles- Individual shingles typically are smaller than strip shingles, and more pieces are required to cover the same roof area than with strip shingles. Particularly in the past, individual shingles were known for their unique visual patterns. Scalloped, fish scale, diagonal, diamond and octagon are a few of the patterns that can be achieved with individual shingles.
