Asphalt shingle roofing is basically of two types that is, fiberglass base and composition shingles. The core in a fiberglass base shingle have man made fiberglass matting and the core of composition shingles are of organic felt i.e. made from paper and wood fibers.
Both these types of shingles are saturated in asphalt, but the organic shingles are less fire resistant than the fiberglass base ones. Mineral granules are embedded on the surfaces of the asphalt shingles so that they offer protection against sun’s ultraviolet radiation and wear and tear. When the granules start to get washed away, it is a sign that the shingles have to be repaired or replaced. Asphalt shingles of four types are manufactured, which are, strip shingles, large individual shingles, interlocking shingles, and laminated shingles.
The strip shingles which are basically the conventional type of shingles are made in both metric and standard sizes. Mostly, they have a width of 12 inches and length of 36 inches and among these the most common ones are the ‘three tab’ shingles. These shingles have a cutout which distinguishes each tab, thus giving a look of an individual shingle of 12 inch width. Various patterns of light and shadow on the roofs can be created depending on the alignment of these tabs.
The large individual shingles do not have tabs and they tend to be either of rectangular or hexagonal shape. They are mostly used in specialty situations. The interlocking shingles are designed in a way that they fasten to each other easily and are best for areas with high wind. The laminated shingles are also known as 3 dimensional or architectural shingles. They vary in number, thickness, size and spacing of the tabs, and also their visual depth and character is more than the standard strip shingles.
As asphalt shingles are available in a wide range of colors, patterns, weights and textures, choosing from them can be a difficult task. Compared to the standard shingles of 230 pounds/square, most people prefer the premium weight shingles having a weight of 430 pounds/square or a roof area of 10 by 10 feet. Also, the premium weight shingles are more 3 dimensional and do a better job of imitating the real wood shingles’ texture.
