Composite shingles, which are also known as composition shingles, asphalt shingles or composition asphalt shingles, are the most common type of residential roofing material used in the United States. They are manufactured by coating an inner core with asphalt and then pressing granules into the coating. Organic composition shingles have a core of paper or felt; fiberglass composition shingles have a core of fiberglass mat. Both types of shingles are available in three styles: three-tab, dimensional and architectural.
Three-tab shingles were one of the first asphalt shingles offered in pre-cut, standardized sizes. They give the roof a flat, one-dimensional appearance that is nevertheless attractive. In America, three-tabs are the most widely sold type of shingles, primarily because they are the least expensive. Three-tab shingles are produced in an extensive range of colors. Manufacturers’ warranties vary, but most are between 20 and 30 years.
Dimensional Composite Shingles
Dimensional composite shingles are a step up from three-tabs. During the manufacturing process, a second layer is laminated to the base shingle, and this second layer produces a three-dimensional look. Dimensional shingles are heavier than three-tabs. They normally have warranties of 30 to 40 years, but some are available with longer warranties. Due to their weight as well as their laminated construction, many dimensional shingles cannot be installed over existing shingles.
Architectural Composite Shingles
Architectural composite shingles are often referred to as premium shingles. They are the heaviest and most expensive of the three basic types of asphalt shingles. Like dimensional shingles, architectural shingles have a three-dimensional appearance, but premium shingles offer enhanced dimensionality through areas of contrast and shadow. Some styles of architectural shingles are virtually impossible to distinguish from wood shakes or slate when viewed from the ground. Warranties on architectural shingles typically start at 40 years, and some carry lifetime warranties.
Pros and Cons of Composite Shingles
Composite shingles are attractive and economical, and all styles are available in a variety of colors. Organic and fiberglass styles are highly resistant to water penetration and fire, but fiberglass composite shingles have a slight advantage over organic shingles in both areas. In a high wind or during wind damage, a roof may lose a few shingles, but replacement is fast and economical. If an area of the roof is heavily shaded, moss or mold may find a hospitable environment for growth; there are products that your roofer can install to solve the problem.
